China’s nuclear icebreaker marks a new phase in Arctic shipping strategy

From Federica Shipping Brief

China’s Arctic strategy is entering a new phase — one defined less by symbolic research presence and more by hard maritime capability.

In December, the state-run 708 Research Institute unveiled a conceptual design for a nuclear-powered, bull-nosed icebreaker capable of breaking through floes up to 2.5 metres thick.

Officially described as a “multirole” cargo and polar tourism vessel, the ship is intended to serve as a prototype for China’s emerging polar fleet.

While framed in commercial and research terms, the development is best understood within the broader context of shipping security, trade resilience and long-term commodity access.

The industrial base: dual-use capacity

The strategic signal lies not only in the ship itself, but in who is building it.

The yard responsible for China’s first indigenous icebreaker also delivered the aircraft carrier Fujian, now operated by the People’s Liberation Army Navy.

That yard falls under China State Shipbuilding Corporation (CSSC), one of the world’s largest shipbuilding conglomerates.

For maritime observers, this matters.

Icebreakers are not simply commercial assets.

They are sovereignty tools— enabling year-round access, hydrographic mapping, escort capability and sustained presence in contested or infrastructure-poor waters.

A nuclear-powered platform, in particular, signals endurance and strategic commitment rather than seasonal experimentation.

The trade logic: distance, diversification, and redundancy

Beijing’s 2018 Arctic policy introduced the concept of a “Polar Silk Road.”

The core argument is geographic: Arctic routes, particularly via Russia’s Northern Sea Route (NSR), can cut voyage distances between northern China and northern Europe by 30–40% compared to the Suez Canal corridor.

In September, the container vessel Istanbul Bridge sailed from Ningbo to Felixstowe via the NSR — described in Chinese state media as the opening of a “China-Europe Arctic Express.”

From a freight economics perspective, however, several realities remain:

• Seasonality limits predictable scheduling.
• Ice-class premiums and insurance costs erode distance savings.
• Search-and-rescue and port infrastructure remain underdeveloped.
• Sanctions exposure and geopolitical risk complicate Western-facing trade.

For southern Chinese exporters, Suez often remains operationally faster despite longer nautical miles.

In other words, the Arctic is not yet a Suez replacement.

It is a strategic hedge — a redundancy option in a fragmented global trade system increasingly shaped by chokepoint risk.

Commodities: energy, minerals and Arctic logistics

Where the Arctic becomes more structurally significant is in commodities.

China has expanded investments in Russia’s north, including coal developments near Murmansk and port infrastructure in Arkhangelsk.

State shipping giant COSCO Shipping is widely expected to anchor logistics activity through Arctic gateways.

The Arctic offers three strategic commodity levers:

• Hydrocarbons — LNG and offshore oil potential.
• Critical minerals and rare earths — increasingly central to energy transition supply chains.
• Alternative export corridors for Russian volumes, particularly as sanctions reshape global flows.

As Arctic ice coverage declines, extraction and shipping windows expand.

Over time, that shifts the economics of upstream investment and midstream transport.

Governance and geopolitical friction

China describes itself as a “near-Arctic state,” a classification rejected by several Arctic governments. The eight Arctic states have historically limited formal governance roles to themselves.

Meanwhile, Washington has earmarked $9bn for icebreakers and polar infrastructure to maintain US leadership in the region.

NATO-controlled territories — including Canada and Greenland — sit astride key North Atlantic access points.

Yet analysts note important nuance:

• Chinese naval patrols with Russia have increased near Alaska.
• There has not yet been a confirmed Chinese military vessel operating in the central Arctic Ocean.
• The Northern Sea Route’s narrow passages and short seasons limit military utility in a conflict scenario.

What this means for shipping and commodity markets

For maritime and commodity participants, the Arctic is no longer a theoretical trade lane. It is an emerging strategic variable.

Three implications stand out:

• Route optionality will become a core element of supply-chain resilience.
• China–Russia energy integration in the Arctic will deepen, particularly around LNG and minerals.
• Icebreaking capacity will increasingly define access, influence and commercial advantage in polar waters.

The Arctic will not displace Suez in the near term.

But with nuclear-powered icebreakers, port investments and state-backed shipping, Beijing is positioning for a long-term structural presence in northern trade routes.

For markets, the key question is not whether the Arctic will matter — but when its economics begin to align with its geopolitics.

Aleksander Doba kayaked solo across the Atlantic Ocean three times

Aleksander Doba kayaked solo across the Atlantic Ocean, covering roughly 5,400 kilometers under his own power, ns the only person to kayak the Atlantic solo three separate times, totaling over 18,000 miles, with his last crossing completed in 2017 at the age of 70.
In 2021, while climbing Mount Kilimanjaro, he successfully reached the summit.

After asking for a brief rest before taking a photo, he sat down on a rock and peacefully “fell asleep,” passing away at the top of Africa.

From Adventure Journal

On February 22, Aleksander Doba made the last few strides to the top of Kilimanjaro, a pleased 74-year-old man, waving to fellow climbers with his envy-inducing muscular arms, a smile beaming from behind the curls of a wild beard.
He shouted his happiness for achieving his goal of climbing this mountain with the enchanting name.
Doba took a look around, admiring the view from the world’s highest freestanding mountain, sat down on a nearby rock, and died.

While it’s perhaps not entirely surprising that a man of that age would die of HAPE (high altitude pulmonary edema) at such an altitude, it might surprise many who knew him that after all Doba had been through, hiking to the top of Kilimanjaro would kill him.
Some might have been surprised that anything could.

Late in life, Doba paddled solo across the Atlantic Ocean three times.
He was 64 years old his first time.
He was 70 during his final crossing in 2017.
He holds a bushel of world records for his almost unbelievable paddles.
He should hold more for his beard.

His wife’s homemade jams were possibly the secret to his success.
Each time he’d step out of his kayak on shaky feet after one of his mammoth crossings, fresh after facing giant waves, relentless sun, broken equipment, and a body rendered into jerky from salt air, with reporters standing by for a juicy quote about man against nature and the perils of the sea, Doba would hold up a jar of his wife’s jam and praise her efforts for that particular batch.
It was the performance booster that kept the man going.

As the ship lingered, the captain confused, Doba shouted Polish curses at the crew and they took a hint.

Doba was born in 1946 in Swarzędz, Poland, smack in the middle of the country.
Access to the sea was nonexistent, but he had rivers and he used them.
Doba loved whitewater kayaking as a youngster in Poland and took it seriously, competing in whitewater slalom events.
He was invited as a young man to join a kayaking club, enthusiastically accepted, and set about paddling all the way from the middle of the country to the Baltic Sea, an illegal act in the Communist country.
He feigned confusion when halted by soldiers, explaining he had no idea how far he’d paddled, he was just out for a river cruise.

In his 30s, he took an interest in big-water kayaking, eyeing Russia’s massive Lake Baikal, which he circumnavigated successfully.
In 1989, he kayaked the length of the Baltic Sea’s shoreline, spending 100 days on the water.
Later, he paddled more than 5,300 kilometers from rivers in Poland to the open sea and the Arctic Circle.
Once, on that trip, he was pitched overboard, and washed up on a beach; he awoke shocked to find himself lying alive on the sand, with no idea how he got there.

Still, Doba had no reason to plot a trip across the Atlantic, let alone three such trips.
After all, he had a pleasant life as a chemical engineer in Poland, and plenty of homemade jam to eat back at home.

In 2003, Doba was advising a fellow paddler about how to tackle the Baltic Sea.
The two men got to talking, and eventually, they’d decided, forget the Baltic, they were going to cross the entire Atlantic.

Ghana to Brazil.
Their plan was to take separate kayaks, but lash them together at night so they wouldn’t drift apart.
Some time later they headed out from the Ghanian coast, visions of glory illuminating their watery path.

They didn’t make it two days before they were washed up on a lonely beach, their plan in tatters.
But Doba was hooked on the idea and plotted his return, this time without a fellow paddler to consider.

“With my hand on my heart, it wasn’t my idea,” Mr.
Doba told the NYT Magazine in 2018.
“I was infected with a virus.”

That paddling virus compelled Doba to embark on his solo paddle in 2010 at the age of 64.

He’d spent ten years designing and testing his kayak, the Olo.
When it was ready, he transported it to Senegal, carefully packed the hold with jam, freeze dried goulash, and homemade wine, and shoved off, the bow pointed at Brazil.

99 days later, Doba arrived in South America.
His skin was flayed from the sun and the salt and the ever-present moisture from the steaming hot tropical ocean.
He had conjunctivitis.
His fingernails and toenails had long since rebelled from the torture he put them through and peeled off somewhere in the middle of the Atlantic.
So had his clothes, in fact.
The constant wetness was impossible to dry, so he paddled most of the way stark naked.

But, he survived, and immediately started plotting another trip, but at a slightly higher latitude.

Three years later, Doba was ready to cross the Atlantic again, this time preparing to depart Europe from Portugal, with a planned arrival in Florida.
His wife, unhappy with this obsession, refused to drive him to the airport so he could fly to Portugal to begin his trip.
She still gave him jam.

This trip was smooth paddling for the first few months until Doba noticed his satellite phone had konked out.
Unwilling to lose that precious line to the outside world, he signaled for help using the SOS function on his SPOT device.
A Greek tanker eventually tracked him down, and drew its massive bulk alongside to offer rescue.
Doba tried to communicate that he simply wanted assistance with his phone and communication, though there was a significant language barrier.
Doba rebuffed the ropes thrown over the side by the crew, and waved away the hulking tanker.
As the ship lingered, the captain confused, Doba shouted Polish curses at the crew and they took a hint.
Doba continued paddling west.

You may notice a theme here, one of irreverence, charm, of a man tickled to be alone, at sea, baffled at his own accomplishments, defiant of authority and those who would tell him “no.” Doba cherished the sights and experiences he enjoyed at sea.
He paddled with sea turtles, was astonished to have whales drift alongside his craft, wished upon shooting stars in impossibly starlit skies, far from any source of light.

His final crossing was in 2017, at 70 years old.
This time, he headed east, departing from New Jersey for France.
The trip took 110 days, and, an old hand at this now, Doba again paddled naked, dined on fresh fish he caught, and savored the attention when he arrived in Europe, a Polish national hero.

There are statues of Doba in his native country.
Selfies taken with Doba are treasured by his fellow Poles who encountered him near his home.
He was active giving lectures and eager to share his stories with adventure-seekers.
He was thrilled to be hiking Kilimanjaro, telling an interviewer: “Kayaks did not dissuade me from other forms of exploring the world.”

Doba would hold up a jar of his wife’s jam and praise her efforts for that particular batch.
It was the performance booster that kept the man going.

As Doba ascended the mountain on his last day on Earth, he passed a Polish climber, who was excited to come face to face with a national celebrity.
“I wished him luck in reaching the summit,” said Boguslaw Wawrzyniak.
“Then I asked the local guides with him, ‘Do you know who this man is?’ And they said: ‘Yes.
We know who this is. He is the king of the ocean.’”

“He said many times that he didn’t want to die in his bed,” said Doba’s son Czeslaw.
“From what we gather, he was euphoric to reach the summit. Then he sat down and fell asleep.”

To sit down happily atop Kilimanjaro, one of the seven summits, 20,000 feet into the sky, to rest your weary and battle-scarred 74-year-old bones, there to expire from effort, is, perhaps, not at all a bad way to pass from this world to whatever comes next.

5 facts about the Gulf war that make it an energy and shipping conflict

From The Shipping Brief by Federica Maiorano

The conflict unfolding around the Strait of Hormuz is rapidly evolving beyond a conventional military confrontation.

What is emerging instead is something more consequential for global markets: an energy and logistics crisis centered on the Gulf’s infrastructure and maritime chokepoints.

The region sits at the heart of the global hydrocarbon system, and the escalation we are now seeing reveals how fragile that system can be when geopolitics intersects with physical supply chains.

Below are five structural realities shaping the conflict and its implications for energy and shipping markets.

1. Energy infrastructure has become a primary battlefield

One of the clearest signals from the conflict so far is that energy infrastructure is no longer a secondary target — it is central to the strategy.

Facilities such as Saudi Arabia’s Ras Tanura Refinery and the massive LNG export complex at Ras Laffan Industrial City illustrate the scale of what is at stake.

These sites are not just industrial facilities; they are nodes in the global energy system.

The Gulf region accounts for roughly:

• ~20% of global oil supply
• ~20% of global LNG supply

Disrupting even a portion of this capacity can quickly ripple through energy markets.

What makes this phase of the conflict particularly striking is how inexpensive the tools of disruption have become.

Drone strikes and asymmetric attacks can threaten assets that took decades and hundreds of billions of dollars to build.

This creates a profound imbalance: cheap weapons targeting extremely expensive infrastructure.

2. Shipping activity has effectively collapsed

The second front in this conflict is maritime.

The Strait of Hormuz is one of the most critical shipping routes in the world. Roughly 20 million barrels of oil per daynormally transit this narrow waterway, alongside large volumes of LNG and other commodities.

But in recent days, commercial traffic has dropped sharply.

Some maritime intelligence reports suggest very few international vessels are crossing the Strait, apart from Iranian shipping.

This disruption extends far beyond hydrocarbons.

Several other commodity supply chains rely heavily on the Strait, including:

• aluminium exports from the Gulf
• fertiliser feedstocks such as urea and sulphur
• petrochemicals
• other bulk commodities

The consequences are already visible across the shipping market.

War risk insurance premiums have surged, freight risk has increased dramatically, and many shipowners are reassessing whether the route is commercially viable under current conditions.

Iranian officials have further escalated tensions by warning that “not a single litre of oil” would leave the Gulf while attacks against Iran continue.

If enforced, such a strategy would effectively weaponize one of the world’s most important maritime chokepoints.

 

3. Storage and logistics constraints are creating a cascading crisis

A less visible but equally important dimension of the crisis is logistics bottlenecks within the producing countries themselves.

If exports are blocked, oil producers eventually face a simple physical constraint: they run out of storage capacity.

Tank farms fill quickly when production continues but tankers cannot load.

Once storage reaches its limits, producers have no choice but to shut in production.

Countries such as Iraq are particularly vulnerable to this dynamic because their storage capacity is limited relative to production levels.

Even where alternative export routes exist, they offer only partial relief.

Saudi Arabia can divert some crude through the East–West Pipeline, which transports oil to terminals on the Red Sea.

The UAE has a similar bypass route through the Habshan–Fujairah Pipeline, allowing exports to reach the Gulf of Oman.

But these pipelines cannot replace the full capacity of the Strait.

At best, they allow a fraction of normal export volumesto continue moving.

The result is a cascading supply problem: once exports slow, production reductions often follow.

4. Kharg Island is the strategic wildcard

Amid all the escalation, one location remains conspicuously untouched: Kharg Island Oil Terminal.

Kharg Island in the GeoGarage platform (UKHO nautical raster chart)
 

This small island handles around 90% of Iran’s crude exports and is one of the most strategically sensitive pieces of energy infrastructure in the region.

So far, the United States and Israel appear to have deliberately avoided targeting it.

The reason is straightforward: striking Kharg would likely trigger a far broader escalation.

Such an attack could provoke:

• retaliatory strikes on Gulf energy infrastructure
• a severe disruption to regional oil exports
• a significant shock to global energy markets

In other words, Kharg Island represents a strategic red line.

As long as it remains untouched, there is still some containment in the conflict.

But if that line were crossed, the consequences for global energy markets could be profound.

5. The global energy system is structurally fragile

Taken together, these developments highlight a deeper structural reality.

The global energy system depends on a small number of highly concentrated infrastructure hubs and maritime chokepoints.

When those assets become exposed to geopolitical conflict, the system can be destabilized far more easily than many market participants assume.

Low-cost asymmetric warfare — whether drones, sabotage, or maritime disruption — now has the potential to:

• damage critical infrastructure
• halt shipping routes
• destabilize commodity flows
• move global prices

The Gulf conflict is therefore not just a regional war.

It is also a stress test for the architecture of the global energy and shipping system.

And the results so far suggest that architecture may be far more fragile than markets once believed.

GPS denied: time to upgrade

From Pulse by Mark Munsell, former Chief AI Officer of NGA

The Fragile Foundation of Modern Navigation

The Global Positioning System (GPS) is arguably the greatest dual-use technology ever developed.
It saves us trillions of dollars in wasted fuel and inefficient logistics.
However, our modern world is built on a system that is terrifyingly fragile, highly vulnerable to jamming, spoofing, and the existential threat of anti-satellite weapons.

Recent events prove this vulnerability.
On February 28, ships navigating the Strait of Hormuz started appearing on tracking screens in places they couldn't possibly be.
They appeared to be sitting on airport runways, parked on Iranian land, and clustered at nuclear power plants.
More than 1,100 commercial vessels had their navigation systems scrambled in a single day following US-Israeli airstrikes on Iran, bringing a waterway that handles a fifth of the world's oil exports to a halt.

A similar crisis unfolded months earlier in the Caribbean.
During a U.S. standoff with Venezuela, jammed signals caused commercial flights to experience severe GPS problems, resulting in a near-collision for a JetBlue pilot and forcing a cruise ship to navigate by charts and landmarks for three hours.

These are no longer isolated incidents.
Today, anyone can pull up independent tracking sites like gpsjam.org—which aggregates aircraft data to visualize daily GPS disruptions worldwide—and view a heat map of the globe bleeding red with active interference.

But conflict zones aren't the only risk.
In 2013, a truck driver with a $100 jammer accidentally knocked Newark Liberty International Airport's GPS offline just to hide from his employer's vehicle tracker.
This system is used by over 6 billion people, yet it could be blinded by cheap gadgets bought off of eBay (now illegal btw).

The Invisible Metronome

GPS was designed for military position, navigation, and timing in the 1960s and 70s.
Its signals travel 20,000 kilometers from space, arriving 100,000 times weaker than ambient noise.
This makes them easily overwhelmed by low-cost eBay jammers emitting stronger radio noise on the same frequency.

Crucially, GPS isn't just a map; it is the invisible metronome for the modern world.
The atomic clocks on GPS satellites synchronize cellular networks, timestamp billions of financial transactions, and regulate power grids.
Lose the timing signal, and our global digital infrastructure fundamentally breaks down.
We've wired the heartbeat of the global economy to a whispering radio signal from space.

Diverging Strategies: U.S. vs. China

The U.S. government has focused its response almost entirely on advancing military resilience measures like encrypted M-code signals and anti-jam antennas.
This does nothing for commercial pilots or global logistics networks navigating denied environments.
The U.S. defends GPS purely as a military asset.

Meanwhile, China has taken a radically different approach.
It has poured state investment into the BeiDou satellite system, which achieved full global coverage in 2020 and surpasses the U.S. network in size.
In parallel, China has built a deep bench of geospatial experts and backed BeiDou with a layered terrestrial architecture that includes a 20,000-kilometer fiber network and a national eLoran system.
By actively exporting BeiDou through the Belt and Road Initiative and achieving full-stack autonomy in domestic navigation chips, China is building an ecosystem with commercial and strategic leverage that will matter as GPS-denied environments become the norm.

Moving Beyond GPS 2.0

The private sector is beginning to field alternative positioning systems, but competing against “free” will require game-changing innovation, not just incremental improvement.
Inertial navigation systems are expensive and drift over time.
Satellite constellations that simply move GPS-like spacecraft closer to Earth carry many of the same vulnerabilities as the system they’re meant to replace.

Commercial alternatives must go beyond GPS 2.0 to address both resilience and new use cases that justify adoption on their own merits.
Remarkable new startups like EarthTraq aim to fill these gaps by providing new purpose-built constellations paired with low-cost, low-powered devices not dependent on any GPS constellations.
Other companies are actively using computer vision or radar to automatically determine positions with what I call "artificial intelligence dead reckoning." 

Powerhouse companies like Vantor and Niantic Spatial are going big on high fidelity photogrammetric digital models of the world for precision navigation in denied environments.
Other examples, Skyline Nav AI uses computer vision and deep learning to determine a vehicle's location in real time based solely on its surroundings.
Similarly, European startup Vydar uses onboard AI to match live camera feeds of the ground with offline maps, computing highly accurate coordinates even during a complete GPS blackout.
Daedalean AI is taking a complementary approach, building visual positioning systems that integrate seamlessly with radar and inertial sensors to operate in challenging conditions like fog or darkness.
All of these alternatives offer mission performance that GPS cannot and have great promise to supplement or replace it in a denied environment.

We’re all going to have to get used to a world without GPS.
The era of implicit trust in a single vulnerable satellite network is over.
If we want to safely operate autonomous systems and AI in the real world, we must develop higher-fidelity methods of positioning within the eternal reference frame that cannot be defeated by cheap eBay jammers.
It's time to make the system resilient, redundant, and reliable through alternate means to make autonomous AI-driven navigation a reality.

Shift in the Gulf Stream could signal ocean current collapse

The Gulf Stream ocean current carries warm water from the Gulf of Mexico up the US east coast

From New Scientist by Alec Luhn

 
Models show that as the Atlantic Meridional Overturning Circulation gets weaker, the Gulf Stream will drift northwards.
There are signs that this is already happening, and a more abrupt shift could warn of more severe climate impacts

A gradual northward shift in the Gulf Stream has provided more evidence that the system of currents that keeps Europe warm is weakening.
What’s more, modelling suggests that any abrupt shift in the Gulf Stream could signal an imminent, catastrophic collapse in the ocean current.

The Atlantic Meridional Overturning Circulation (AMOC) is the flow of warm, salty surface water from the tropics to north-western Europe, where it cools and sinks, returning south along the ocean floor.
The part of this circulation running from the Gulf of Mexico up the US east coast to North Carolina, where it veers east into the Atlantic, is called the Gulf Stream.

The AMOC is expected to lose strength as the melting of the Greenland ice sheet dumps fresh water into the north Atlantic, diluting the dense, salty AMOC water and slowing the rate at which it sinks and flows southward.
Some research suggests that this is already happening, but scientists don’t have direct proof.
Now, a modelling study by René van Westen and Henk Dijkstra, both at Utrecht University in the Netherlands, has shown that a weakening AMOC would shift the path of the Gulf Stream so it follows the US seaboard further north before it veers into the Atlantic.
Moreover, the study finds the Gulf Stream has already shifted northward by about 50 kilometres in 30 years, according to satellite data.
“This is something we can measure,” says van Westen.
“So it is very likely that this reflects that the AMOC is indeed weakening.”
Reconstructions that estimate the AMOC flow rate based on historic sea temperatures suggest it has weakened 15 per cent since 1950.
But its actual flow has only been monitored by moored instruments since 2004, not long enough to say whether observed changes are natural fluctuations or a trend.
“Therefore, we are trying to come up with some alternative approaches, such as the Gulf Stream path,” says van Westen.
The model in the study represents the world in 10-kilometre pixels rather than the typical 100-kilometre pixels, allowing the researchers to track the bulge where the Gulf Stream is carrying masses of water.
The path of the bulge changes because of the Deep Western Boundary Current, one of the arms of the AMOC carrying cold, salty water southward along the seafloor.
This current normally flows down the coast of North America under the Gulf Stream, tugging it to the south.
As the AMOC weakens, so does the Deep Western Boundary Current, and the curve of the Gulf Stream gradually shifts northward.
However, 392 years into the simulation’s future, the Gulf Stream jumps more than 200 kilometres to the north in just two years.
Twenty-five years after that, the AMOC collapses.
Previous research has shown that such a collapse would drastically cool Europe; London could see cold snaps of -20°C (-4°F) and Oslo, Norway, could reach -48°C (-54°F).

The modelling is an idealised scenario that does not suggest the AMOC will collapse in 400 years.
But it does suggest an abrupt shift in the Gulf Stream could serve as an early warning of an impending AMOC shutdown, the only such prior indicator we know of.
While it may be too late at that point to avoid AMOC collapse, Europe could prepare by insulating houses and finding more southerly places to grow food.
“There is now a very proper early warning indicator that actually goes off,” says van Westen.
“You can measure this very easily.”
But it’s unclear in the real world how long after a Gulf Stream shift the AMOC could collapse.
And projections of when the AMOC might shut down range from decades to centuries.
Dan Seidov, an oceanographer retired from the US National Oceanic and Atmospheric Administration, cautions that fresh water from Greenland could “hose” the AMOC at a different rate and in a different place from what the model assumes.
“How, when and why it may or may not happen is the big question,” he says.
“If it happens as is prescribed in the model, then the Gulf Stream can be a precursor and provide a warning signal.”
While the link between the abrupt shift and AMOC collapse will need to be corroborated by other models, this study provides more evidence the AMOC is already slowing, says Stefan Rahmstorf at the University of Potsdam in Germany.
“This slowing is occurring earlier than in the global warming scenarios,” he says.
“Climate models appear to underestimate the problem and thus potentially how soon an AMOC tipping point will be reached.”

It is a study of wealth, patronage and money, in an England riven by religious disorder and toxic politics.

Greenvile Collins (1643–94) was a naval warrant officer who caught the attention of a King.

His seagoing career took him from Patagonia to the Arctic, into battles against Dutch men of war and Barbary corsairs, and to the slave markets and Silk Road ports of the Mediterranean.

A scientific navigator, his professional drive drew him to Shetland, the Scilly Isles and all points in between, as he undertook the most ambitious hydrographic survey of the British coastline yet attempted.

Then, even as he laboured to complete his monumental sea atlas, he was summoned yet again to the service of the Crown.

The Glorious Revolution was a campaign of crisis for a deeply conflicted Royal Navy, and a crucial test of loyalty for Greenvile Collins and his fellow officers.

Reviews

‘Fascinating and elegantly written, Master & Cartographer introduces a largely-forgotten naval hero of Stuart England’
N.A.M. Rodger, author of The Safeguard of the Sea, The Command of the Ocean and The Price of Victory

‘Greenvile Collins emerges as a sympathetic hero, who served three kings while compiling invaluable charts and navigational data for his fellow sailors. Not since Patrick O’Brian’s Aubrey-Maturin novels have I enjoyed such rollicking armchair adventures at sea’
Dava Sobel, author of Longitude

‘A triumph. Far more than just the man who charted Britain, Greenvile Collins developed faster survey techniques, commanded ships, fought in battle, and ended his career as the leading hydrographer of the Navy. Alan Harper’s major contribution places Collins in a critical series of events, linking charts and navigation with wars and the fast-paced transitions that occurred after 1688, adding a significant new dimension to the naval side of that tumultuous year’
Andrew Lambert, Laughton Professor of Naval History, Kings College, London

‘Very worthwhile – the author has an excellent grasp of his material, writes well, and his seagoing experience adds colour and interest to a compelling narrative’
Dr David Davies, author of Pepys’s Navy and Kings of the Sea, chair of the Society for Nautical Research

 

What is S-100 and how will it affect the future of electronic charts?

From January 2029, retrofits must also be S-100 compatible.

From Practical Boat Owner by Laura Hodgetts

“S-100 is indeed a great step forward. However, it does not promise any new chart data in the areas where leisure boaters frequent", says the Royal Institute of Navigation (RIN) Small Craft Group chairman Paul Bryans.

S-100 “is already the foundation for the next generation of navigation systems”, Emma Wise, director of cartography at Teledyne Maritime, has explained.
This framework for data standards has been developed by the International Hydrographic Organization (IHO) – an intergovernmental organisation that works to ensure all the world’s seas, oceans and navigable waters are surveyed and charted.

Wise told the RIN Small Craft Navigation in 2026 and beyond event: “Currently, many hydrographic organisations around the world are now changing their charting schemes to grids.”

Although there is no ‘universal’ gridding system – which refers to the scheming of charts, often unseen by mariners and small craft users – the worldwide move to grids should mean greater alignment as S-100 data becomes available.

Wise said S-100 will have a commercial-sector focus – it is primarily developed for commercial shipping and SOLAS – however small boat sailors can expect a benefit rollout of S-100 product groups offering ‘richer situational awareness; safer and more predictable nearshore operations; and better decision-making tools’.

The UK Hydrographic Office told PBO the S-100 framework extends across multiple systems, and users and organisations expected to benefit include ports, defence, hydrographic offices and marine users.

 

‘Layers of information’

Like Google maps shows users multiple layers from terrain, to traffic and local amenities, Wise said S-100 brings to life “layers of information like Lego.”

‘Premium’ versions will include high-resolution bathymetry, surface currents and navigational warnings.

She added: “It provides also a unique opportunity for autonomous and uncrewed vessel navigation.”

From 2027, new chart plotters and multifunction displays (MFDs) must adapt to S-100, and will need more computer power for multi-layer renderings.

Missing chart data

Paul Bryans, chairman of the RIN Small Craft Group, said: “S-100 is indeed a great step forward.

“However, it does not promise any new chart data in the areas where leisure boaters frequent.

“That was highlighted in the Pleasure Vessel Navigation Systems Working Group (PVNSWG) report ‘gap analysis’ and remains our main concern.

 

 

“S-100 is aimed at the 3,000GT-plus shipping market but there will be spin-off benefits for other user groups, like improved tidal data presentation.

“However, proposed new chart standards for vessels below that size should allow the ‘leisure’ chart publishers to continue to provide enhanced solutions for the small craft market.”

In the latest Electronic Navigation Systems – Guidance for safe use on leisure vessels free booklet, under a section called ‘Shortfalls of electronic navigational charts (ENCs) for leisure use, it states:

“Official ENCs, which are displayed on electronic chart display and information systems (ECDIS) and small vessel – electronic chart systems (UK MCA performance standard) (SV-ECS), were designed primarily for the shipping sector (greater than 500GT).

“Features significant to smaller vessels used to be depicted on paper charts, including features that had been shown on older withdrawn charts, but many of these were omitted when ENCs were first created.

“With a focus on the needs of larger vessels, these omissions helped to reduce screen clutter.

“New surveys commissioned by hydrographic offices for ENCs also tend to focus primarily on commercial shipping routes, commercial ports and deeper waters.

“Few new surveys are commissioned for shallower inshore waters used only by leisure vessels.

“Consequently, ENCs currently do not display all the data needed by less than 24m vessels, which frequently navigate in areas inaccessible to vessels greater than 500GT.

“Over the years, this gap has been filled by the leisure chart providers in one form or another.

“ENCs are purchased on subscription for individual chart cells and are very expensive as there is only one pricing plan for all vessels.”

At a Glance

• Commercial traffic through the Strait of Hormuz remains extremely limited, with only three outbound crossings recorded on March 15 and no inbound transits.
• Maritime security risk across the Gulf remains high, with 20 confirmed incidents involving commercial vessels and offshore infrastructure recorded since the start of the Iran war.
• Kharg Island remains operational despite recent strikes, with multiple tankers still present near the terminal even as export volumes remain well below pre-war levels.
• Route redistribution remains active, with Bab el-Mandeb traffic sharply reduced, Suez Canal volumes rebounding, and Cape of Good Hope diversion traffic staying elevated.
• Regional logistics strain is increasing outside the Gulf, particularly at Salalah and Karachi, while Saudi Arabia continues expanding its Red Sea crude export workaround.
• Maritime security pressure is also widening beyond the Gulf, with a tanker strike in the Black Sea and unusual Russian tanker activity near a damaged Arctic gas platform.

 

Operational Overview

Maritime activity across the Gulf and adjacent shipping systems remained heavily disrupted on March 15 as the conflict continued to distort commercial traffic patterns, energy flows, and maritime security conditions.

Transit through the Strait of Hormuz remained near paralysis, with only three outbound vessels recorded and no inbound crossings.
While that marks a slight increase from the previous day’s full visible halt, activity remains far below normal commercial levels and underscores the continued reluctance of operators to enter the corridor.

The broader security picture remains severe.
Since the start of the Iran war, 20 confirmed maritime security incidents involving commercial vessels and offshore infrastructure have been recorded across the Northern Arabian Gulf, the Strait of Hormuz, and the Gulf of Oman.
Cargo vessels account for the overwhelming majority of affected ships, indicating that the threat environment remains centered on mainstream commercial traffic rather than niche vessel categories.

Beyond the Gulf, global shipping routes continue adjusting.
Bab el-Mandeb traffic remains sharply reduced, Suez Canal volumes partially rebounded, and Cape of Good Hope diversions remained elevated.
At the same time, pressure is growing on alternative logistics hubs outside the Gulf, while Saudi Arabia continues shifting crude exports toward Red Sea infrastructure.

The conflict is also increasingly influencing maritime security beyond the immediate Gulf theater.
A Greek-flagged tanker strike near Novorossiysk in the Black Sea, together with unusual Russian tanker behavior near the damaged Arctic Metagaz platform, suggests that geopolitical maritime risk is spreading across multiple regions at once. 

Strait of Hormuz Traffic

Transit activity through the Strait of Hormuz remained extremely limited on March 15.

Windward recorded three outbound crossings and no inbound transits, marking the first visible movement through the Strait since March 13.
While this represents a 300% increase compared with March 14, when no crossings were recorded, activity remains only marginally above the 7-day moving average of 2.29 crossings and still far below normal commercial levels.

The vessels included one bulk carrier and two vessels classified as other or unknown.
Flag distribution included one Liberian-flagged vessel and one Guyana-flagged vessel.

One of the transiting ships was the sanctioned VLCC NORA (IMO 9237539), which loaded approximately 2.01 million barrels of crude oil at Kharg Island and departed the terminal on March 7.
The vessel is currently en route to Ningbo, China, reinforcing that limited Iranian export flows continue despite the wider disruption.

Maritime Security Incidents

Maritime security monitoring indicates a sustained pattern of attacks against commercial shipping and offshore infrastructure across Gulf waters.
Since the start of the Iran war, 20 confirmed maritime security incidents have been recorded across the Northern Arabian Gulf, the Strait of Hormuz, and the Gulf of Oman.

Map of vessel attacks since the start of the Iran War.
Source: Windward.

Cargo vessels account for the overwhelming majority of affected ships, representing 90% of all attacks.
The breakdown includes eight bulk carriers (40%), six tankers (30%), four container vessels (20%), and two service or support vessels (10%).

Ownership and flag analysis indicate that several affected vessels had Western or Gulf-state linkages.
Three vessels had a U.S.
nexus, three had a UAE nexus, and three had a UK nexus based on ownership or flag state connections.

Geographically, the Northern Arabian Gulf has been the most affected area, accounting for 45% of incidents (9 vessels), followed by the Strait of Hormuz at 30% (6 vessels) and the Gulf of Oman at 25% (5 vessels).

Recent port call analysis also suggests elevated exposure after entering the regional threat environment.
Approximately 45% of targeted vessels had recently called at UAE ports, while 20% had recent Iraqi port calls.
At the same time, the affected vessels also included ships arriving from Thailand, Vietnam, and Brazil, indicating that the risk extends well beyond regionally linked trade alone.

Taken together, the pattern suggests broad targeting of dense commercial shipping lanes rather than a narrow focus on one nationality or operator class.

Bab el-Mandeb and Suez Canal Traffic

 
Bab el-Mandeb

Transit activity through Bab el-Mandeb remained sharply reduced on March 15.

Windward recorded 10 total crossings, consisting of five inbound and five outbound vessels.
That represents a 52.4% decrease from the previous day and remains well below the 7-day average of 20.71 crossings.

The most common vessel subclasses included two bulk carriers, two oil and chemical tankers, and two oil products tankers.
Flag distribution was led by Liberia with four vessels, followed by Singapore and China with one vessel each.

The continued decline reflects persistent operator concern over missile and drone threats to commercial shipping in the Red Sea corridor.

Suez Canal

Traffic through the Suez Canal partially rebounded on March 15.

Windward recorded 39 total crossings, including 17 inbound vessels and 22 outbound vessels.
That represents a 69.57% increase compared with the previous day and places activity above the 7-day average of 34 crossings.

The traffic mix included 11 bulk carriers, six crude oil tankers, and six container vessels.
Liberia led flag distribution with 11 vessels, followed by Panama with five and Sierra Leone with three.

The rebound suggests that some operators are still willing to test Red Sea-linked routing despite the ongoing regional threat picture.

Cape of Good Hope Diversion

Diversion traffic around the Cape of Good Hope remained elevated on March 15.

Windward recorded 82 total vessel transits, including 35 eastbound and 47 westbound crossings.
That represents an 18.84% increase compared with March 14 and remains broadly consistent with the 7-day moving average of 81.57 crossings.

The traffic mix was led by 26 bulk carriers, 21 container vessels, and eight crude oil tankers.
Liberia led the flag distribution with 21 vessels, followed by Singapore with 14 and the Marshall Islands with 10.

These sustained volumes confirm that long-haul diversions around Africa remain a core alternative for operators avoiding Gulf and Red Sea risk corridors.
The result continues to be longer voyage times, higher freight costs, and increased strain on Asia-Europe trade lanes.

Port Operations Disruptions

Operational congestion is increasing across regional ports as vessels adjust routing and transshipment strategies in response to the Gulf conflict.

Inside the Gulf, Jebel Ali recorded 4 transshipment rollovers, up 100% from the previous day,though still 31.71% below the 7-day average, alongside 6 transshipment delay cases, up 200% day-on-day but still 34.37% below the 7-day average.

Outside the Gulf, Karachi recorded 8 transshipment rollovers, up 33.33% from the previous dayand 300% above the 7-day average.
Salalah recorded 26 transshipment rollovers, down 18.75% day-on-day but still 18.18% above the 7-day average, alongside 72 transshipment delay cases, up 100% from the previous day and 168.09% above the 7-day average.

The surge in delays at Salalah highlights its growing role as an alternative logistics hub outside the Gulf conflict zone.

Saudi Arabia’s Red Sea Export Pivot

Saudi Arabia continues accelerating its crude export rerouting through the East-West Pipeline, or Petroline, to reduce dependence on Gulf shipping routes.

Windward data shows weekly tanker port calls at Saudi Red Sea ports increasing from roughly 58 in late December 2025 to more than 90 by early March 2026.

This shift has contributed to a visible buildup of VLCCs near Yanbu, where vessels are waiting to load crude transported across the Arabian Peninsula.
The accumulation underscores the scale of Saudi Arabia’s effort to sustain exports while bypassing Hormuz-related risk.

Black Sea Incident

On March 14, 2026, the Greek-flagged tanker MARAN HOMER, owned by the Angelicoussis Shipping Group and operating under a U.S.
commercial manager, was struck by a suspected drone or small missile while operating in the Black Sea.

The vessel was unladen and waiting approximately 14 nautical miles off the Russian port of Novorossiysk to load crude oil when it sustained minor damage on its starboard side.
All 24 crew members were unharmed, and the vessel was able to depart the strike area under its own power.

Greek Maritime Affairs officials have indicated that the attack may represent a secondary geopolitical consequence of the broader conflict involving Iran, assessing the strike as a possible pressure tactic linked to the recent U.S.
decision to temporarily ease sanctions on Russian oil in order to stabilize global energy markets disrupted by the Gulf conflict.

The incident highlights the expanding geographic scope of maritime security risks, suggesting that commercial shipping may increasingly face asymmetric threats across multiple maritime theaters simultaneously.

Arctic Activity

Unusual Russian vessel behavior has also been observed in the Arctic.

A Russian tanker, assumed to be carrying Wagner-linked or military personnel, has been loitering near the Arctic Metagaz platform since March 9.
The platform experienced an explosion on March 3 that has been widely suspected to be linked to Ukrainian sabotage.

The vessel’s prolonged presence suggests a damage assessment, security, or support mission rather than normal commercial activity.

Emerging Iranian Logistics Activity

Satellite and AIS data indicate renewed movement involving IRISL vessels departing Gaolan Port in Zhuhai, China.

Four Iranian-flagged container ships are currently returning toward Iran.
These voyages follow the earlier departures of Shabdis and Barzin, which reportedly carried sodium perchlorate, a key component in solid-propellant missile fuel.

These movements suggest that Iran-linked logistical and industrial supply chains remain active despite sustained pressure on Gulf shipping.
 

Outlook

The March 16 operating picture points to a maritime system that remains disrupted rather than frozen.
Visible traffic through Hormuz remains extremely limited, reflecting continued operator reluctance to transit the corridor under current security conditions.

At the same time, the broader commercial response still reflects extreme caution.
Vessel accumulation in the Gulf of Oman, reduced Bab el-Mandeb traffic, elevated Cape diversions, and mounting congestion at alternative hubs indicate that many operators continue to avoid direct exposure to the Gulf threat environment.
Maritime security risks are expanding beyond the Gulf theater, illustrated by the strike on the MARAN HOMER in the Black Sea and Russian activity near the damaged Arctic Metagaz platform.

In the near term, maritime activity is likely to remain defined by restricted transit through Hormuz, continued route redistribution across global corridors, and growing pressure on alternative export and transshipment infrastructure.
As the conflict enters its third week, the operational consequences are no longer limited to Gulf shipping alone but are increasingly shaping wider maritime security and trade patterns across multiple regions.

Chinese Intelligence Ship “Liaowang-1” is supposed to be spotted near Oman

But according VesselFinder, the ship is anchored in China

From GreyDynamics

The People’s Republic of China (PRC) deployed the Liaowang-1, its newest maritime space tracking and intelligence vessel.
It marks both a technological leap forward for the People’s Liberation Army Navy’s (PLAN) naval capabilities as well as a strategic assertion of Chinese interests in space and naval domains.
The Liaowang-1 is designed to monitor military satellites, track missile launches, and function as a mobile command and control (C2) centre for space and naval operations.
This new class of tracking ships will replace the Yuan Wang-class ships, which have been in service since 1977.
[source]

In recent years, Beijing has been actively investing in its fleet and now constitutes the world’s largest Navy in terms of total ship count.
The deployment of the Liaowang-1 happens amid US efforts to enhance their space capabilities by deploying 160 satellites into space by the end of 2025.

1 History of the Project

The Liaowang-1 is a component of China’s larger space and military development goals.
Beijing is gradually replacing the outdated Yuan Wang-class ships–in service since the late 1970s–with the new ships.
Liaowang-1, is constructed by the China State Shipbuilding Corporation (CSSC), and is the result of decades of advancements in space tracking and maritime surveillance technologies.
Amid rising international tensions and China’s growing emphasis on fusing the space and marine domains for strategic benefit, the ship was officially launched in 2023.
Its advanced capabilities embody the trend towards a tighter integration of space operations with naval activities.
[source, source]
 

1.1 What is a Tracking Ship?

A tracking ship is an intelligence collection vessel that is equipped with antennas and electronic systems to track missile launches (including intercontinental ballistic missiles (ICBMs)), rockets, and satellites.
As missiles and satellites often cross vast oceanic areas, tracking ships extend the reach of land-based radar by overcoming geographic and curvature limitations.
Equipped with sophisticated sensors, these ships collect telemetry data, monitor trajectories, and provide real-time C2 support for military operations.
They can also enhance electronic intelligence (ELINT) and signals intelligence (SIGINT) capabilities by gathering information on adversary communications and radar emissions.
[source]
 

2 Technical Data

Many of the technical parameters of the Liaowang-1 are unknown to the public, however, available information suggest the following characteristics: Displacement: 30,000 tons
Length: 224 meters
Beam: 32 meters
Equipment: At least five (visible) radar domes with high and low-range radars, high-gain antennas, signal processing systems; likely other sensors, telemetry receivers, and ELINT/SIGINT systems on board.
[source, source]

The ship’s scale and enlarged hull reportedly allow it to host more systems and be more resilient against threats.
Its helipad can support medium-lift helicopters, allowing for better logistics, surveillance, and potential search and rescue capabilities.
With its large displacement, the Liaowang-1 is one of the largest non-combatant ships in the Chinese Navy.
[source]

That said, the specific data about the technology used remains classified.
It is thus difficult to assess how well the ship would perform in a real combat scenario.

3 Mission

As a tracking ship, the Liaowang-1’s mission scenario will likely involve the provision of a mobile, sea-based platform to track satellites, missiles, ICBMs, and other space assets in real-time.
Given the geopolitical tensions between the PRC and the US in the South China Sea and the Pacific, this vessel can be a counterbalance to Washington’s increasing space assets and its upcoming Golden Dome missile defense project.
[source]

The ship’s sophisticated sensors will allow it to enhance PLAN’s situational awareness and surveillance in international waters, beyond the coverage of its mainland stations.
By acting as a C2 node for Beijing’s military, it can facilitate electronic warfare and anti-satellite (ASAT) operations and potentially collect acoustic and electromagnetic data.
[source, source]

Equally important, this forward-deployed intelligence asset serves as a dominant tool for strategic power projection and Beijing’s determination to contest its adversaries far beyond its own borders.

3.1 Role in China’s Maritime Strategy

China’s current maritime strategy is transitioning away from its previously near-coastal focus to a more assertive posture.
This allows the PLAN to operate further away from its territorial waters to defend its global interests, access to resources, and foreign markets.
Beijing seeks to build a blue-water navy to operate far from its borders for economic and geopolitical advantages.
[source]

The Liaowang-1 can support this strategy by enhancing PLAN’s capabilities to protect critical infrastructure and secure key chokepoints.
Its Command, Control, Communications, Computers, Intelligence, Surveillance, Reconnaissance (C4ISR) capabilities allow the PRC to build out its integrated anti-access/area denial (A2/AD) area and challenge US dominance, particularly around Taiwan and in the wider region of the South China Sea.

 

 

Emblem of the PLAN.

4 Conclusion

The Liaowang-1 signals Beijing’s intent to be a key player in maritime and space domains, further enhancing its growing intelligence capabilities.
As a mobile space surveillance platform, it can help monitor US satellites and missile launches, providing a strategic edge in a potential conflict.

The ship is part of China’s broader maritime strategy to project power globally and integrate space and naval assets into its defense components.
Additionally, it portrays the growing importance of multi-domain warfare, where domains such as space and sea grow more intertwined and complex.
