Remembering Titanic: the tragedy behind SOLAS


From Safety4Sea

Claiming the title of the most high-level shipwreck in history, Titanic is far more than a famous tragic story as it redefined the concept of maritime safety and led to the adoption of SOLAS Convention.

The 𝗧𝗶𝘁𝗮𝗻𝗶𝗰 sank on the night of April 14 to 15, 1912.
Here, the images of its launch, in 1911.
Which required 22 tons of tallow, oil, and soap to make it slide.
 
The incident


The British luxury passenger ship RMS Titanic began its maiden voyage from Southampton, England to New York, US, on 10 April 1912.
After calling at Cherbourg in France and Queenstown (now Cobh) in Ireland on the same day, the ship headed west to New York, where it was expected to arrive on the morning of 17 April.

When the ship was about 375 miles south of Newfoundland, on 14 April, 11:40 p.m., lookout Frederick Fleet spotted an iceberg immediately ahead of Titanic and alerted the bridge.
First Officer ordered the ship to be steered around the obstacle and the engines to be reversed, but it was too late; the starboard side of Titanic struck the iceberg, rupturing five of its 16 supposedly watertight compartments below the waterline, while the ship could only survive four flooding.

Titanic began sinking bow-first, with water spilling from compartment to compartment as its angle in the water became steeper.
Meanwhile, distress signals were sent and passengers and some crew members were evacuated in lifeboats, many of which were launched only partially loaded.

At 2:20 am, the ship broke apart and foundered with more than 1,000 people still aboard.
Just under two hours after Titanic sank, the Cunard liner RMS Carpathia arrived and brought aboard an estimated 705 survivors.

Titanic: A timeline of events
14 April, 11:35 PM: Lookout spots an iceberg, rings the bell three times and calls the bridge.
First officer orders the Titanic “hard-a-starboard” (to the left) and the engines reversed.
He also closes the doors to the watertight compartments.
14 April, 11:40 PM: The starboard side of the Titanic hits the iceberg, Captain Smith arrives on deck and is informed that at least five of the ship’s compartments are flooded.
Designer Thomas Andrews surveys the damage, predicting that the ship has only about one to two hours before sinking.
15 April, 12:00 AM: Lifeboats begin to be readied for launch.
15 April, 12:15 AM: Distress signals are sent but most ships that respond are too far away.
15 April, 12:20 AM: The Carpathia receives the signal and immediately changes course to aid the ship, but it will need more than three hours to arrive.
Passengers’ embarkation on lifeboats is underway.
15 April, 12:45 PM: The ship unsuccessfully fires the first of eight distress rockets.
The first lifeboat is launched well below capacity, partially because of the crewmen’s worry that the davits would be unable to hold a fully loaded lifeboat.
15 April, 2:00 AM: The only lifeboats that remain on the Titanic are three of the collapsible boats.
The Titanic’s bow has sunk low enough that the stern’s propellers are now clearly visible above the water.
Captain Smith releases the crew, saying that “it’s every man for himself.” The Captain is reportedly seen on the bridge for the last time.
His body will never be recovered.
15 April, 2:17 AM: Wireless radio operator Jack Phillips sends a final distress signal.
He reportedly makes it to the overturned collapsible lifeboat B but succumbs to exposure.
His body will not be found.
15 April, 2:18 AM: The lights on the Titanic go out.
The ship breaks in two between the third and fourth funnels.
15 April, 2:20 AM: The stern disappears below the water, and the Titanic is gone.
15 April, 3:30 AM: The Carpathia arrives in the area, firing rockets.
15 April, 4:10 AM: The Carpathia begins picking up survivors from lifeboats.
15 April, 8:30 AM: The Californian arrives, searches the area for several hours but fails to find any survivors.
15 April, 8:50 AM: The Carpathia, carrying the 705 Titanic survivors, heads to New York City, where it will arrive on April 18.

Fatalities

All people who did not manage to get on lifeboats immersed in lethally cold water with a temperature of −2 °C (28 °F) and almost all died of cardiac arrest or other bodily reactions to freezing water, within 15–30 minutes.
Only five of them were helped into the lifeboats, though the lifeboats had room for almost 500 more people.

As a result, more than 1,500 people lost their lives, and about 705 were rescued, although theories on the exact numbers vary due to confusion over the passenger list, which included some names of people who canceled their trip at the last minute and some who were double-counted on the casualty lists.

Passengers traveling first class were significantly more likely to survive than other passengers, while women and children were more likely to survive than men, due to a “women and children first” protocol in lifeboats.
To put that into perspective, 387 of the 462 men in third class onboard perished in the disaster, and only 4 out of the 144 women in first class were lost.
Although unsurprisingly, third class suffered the greatest loss, subsequent claims that passengers in steerage were prevented from boarding lifeboats were largely dispelled.
The high death toll in third class was mostly attributed to the lack of a proper general alarm that did not permit passengers to realize the emergency until it was too late, while the difficulty of simply navigating the complex Titanic from the lower levels caused some to reach the top deck after most of the lifeboats had been launched, according to Britannica.

Probable causes

-Climate conditions: 
The immediate cause of the sinking was collision with an iceberg, which reminds us that, in every tragedy, there is human error along with bad luck.
In that time of that year, warmer-than-usual waters in the region made Atlantic waters a fruitful ground for corralling icebergs at the intersection of the Labrador Current and the Gulf Stream, while unusually high tides in January 1912 possibly dislodged icebergs of Labrador Sea sending them towards the Titanic route some months later.
In addition, the two lookouts onboard, Frederick Fleet and Reginald Lee, had a difficult job that night due to the fact that the ocean was unusually calm that night: As there would be little water breaking at its base, an iceberg would be more difficult to spot.
 
Neglecting warnings: 
Titanic received a series of warnings from other ships of drifting ice in the area of the Grand Banks of Newfoundland.
One of the ships to warn Titanic was the Atlantic Line’s Mesaba, a few hours before the tragedy, but the message was never relayed to the Titanic’s bridge.
Shortly after, the nearby Californian notified Titanic that it had stopped after becoming surrounded by ice, but wireless operator Phillips, who was handling passenger messages, scolded the Californian for interrupting him: “Shut up! Shut up! I am busy.”
 
Reversed engines: 
As soon as the bridge was notified of the iceberg, First Officer William Murdoch ordered a “hard-a-starboard”—a maneuver that would turn the ship to port (left)—and the engines reversed.
The Titanic began to turn, but it was too close to avoid a collision.
By reversing the engines, Murdoch actually caused the Titanic to turn slower than if it had been moving at its original speed.
Most experts believe the ship would have survived if it had hit the iceberg head-on, according to Britannica.
It has also been reported that, if the ship had stopped where it was hit, seawater would not have pushed into one interior compartment after another, and the ship might not have sunk as quickly.
 
Timekeeping:
Despite warnings on icebergs, the ship continued to steam at full speed, which was standard practice at the time.
Ice warnings were typically seen as advisories with reliance placed upon lookouts and it was generally believed that ice posed little danger to large vessels.
 
There were too few lifeboats: 
This did not cause the sinking but contributed to the high death toll.
The 20 lifeboats onboard were enough for 1,178 people—about half the number onboard, and one third of Titanic’s total capacity— which was still in excess of the 1,060-person capacity under the maritime safety regulations of those days.
Four of those boats were collapsible and proved hard to launch during the sinking.
Even worse, the lifeboats launched were eventually only about half-filled, because crewmen worried that the davits would not be able to support the weight of a fully loaded boat.
It is worth noting that the Captain had canceled the ship’s scheduled lifeboat drill earlier in the day of the sinking, and the crew was unaware that the davits had been tested in Belfast.
 
Poor practices onboard: 
Due to drill cancellation, the crew had not been trained adequately in carrying out an evacuation.
Those aboard Titanic were ill-prepared for such an emergency in accordance with accepted practices of the time, as ships were seen as largely unsinkable.
Furthermore, many passengers on the aftermath of the sinking testified to the general confusion on the ship: A general warning was never sounded, causing a number of passengers and even crew members to be unaware of the danger for some time.

The role of the SS Californian

The British steamship SS California has been scrutinized over its inaction as it was the closest ship near the accident area, received the distress signals but failed to respond to them in accordance with law.
After warning Titanic of the ice field, the wireless operator turned off his radio.
About an hour later, the crew of Californian see the rockets but fail to determine their source.
Following controversies, it was determined that the Californian could have saved many, if not all, of the lives that were lost.
However, as the true location of the Californian will likely never be conclusively known, some experts believe it was actually some 20 miles (37 km) away and would not have reached the Titanic before it sank.

Liabilities

More than 60 survivors in US and Britain joined forces to sue the White Star Line for $16,804,112 (about $419 million in 2018 USD), which was far in excess of what White Star argued it was responsible for as a limited liability company under American law.

The company petitioned the US Supreme Court in 1914, which ruled in its favor finding that the causes of the ship’s sinking were largely unforeseeable, rather than due to negligence.
This limited the scope of damages survivors and family members were entitled to, prompting them to reduce their claims to some $2.5 million.
Eventually, White Star only settled for $664,000 ( $16.56 million in 2018),

The settlement was agreed to by 44 of the claimants in December 1915, with $500,000 set aside for the American claimants, $50,000 for the British, and $114,000 to go towards interest and legal expenses.

Lessons learned

The extended media coverage and the subsequent worldwide shock, due to the huge death toll, led to major improvements in maritime safety.
The most prevalent one was the establishment of the International Convention for the Safety of Life at Sea (SOLAS) in 1914, which still governs maritime safety.

The 1914 version was superseded by SOLAS 1929, SOLAS 1948, SOLAS 1960 (the first adopted under the auspices of the IMO) and SOLAS 1974.
SOLAS 1974 is still in force today, but it has been amended and updated many times.

The first International Conference for Safety of Life at Sea was called in London in 1913, drawing up rules requiring that every ship have lifeboat space for each person embarked; that lifeboat drills be held for each voyage; and, because the Californian had not heard the distress signals of the Titanic, that ships maintain a 24-hour radio watch.
In addition, the International Ice Patrol was established to warn ships of icebergs in the North Atlantic shipping lanes and to break up the ice.

Did you know?
Titanic is the second largest ocean liner wreck in the world, only being surpassed by its sister ship HMHS Britannic, but is the largest sunk while in service as a liner, because Britannic was serving as a hospital ship at the time of its sinking.
Titanic sinking was the deadliest peacetime sinking of a superliner or cruise ship to date.
Two special survivors were the stewardess Violet Jessop and the stoker Arthur John Priest, who survived the sinkings of both Titanic and HMHS Britannic and were aboard RMS Olympic when she was rammed in 1911.
As passengers waited to enter lifeboats, they were entertained by the Titanic’s musicians, until shortly before the ship sank.
None of them survived the sinking.

China publishes maps detailing minerals on the ocean floor

From NY Times by  Sachi Kitajima Mulkey

The new deep-sea atlas underscores Beijing’s interest in ocean mining, its military ambitions and its claims to disputed waters.


A research arm of the Chinese government said it had published an atlas of deep-sea mineral deposits, highlighting Beijing’s ambitions to mine the ocean floor and underscoring its disputed claims to waters that neighboring nations consider theirs.

Experts say the maps, in addition to pinpointing mineral deposits found in the deep ocean, give China’s military a thorough understanding of the seafloor in strategically important waters, providing an advantage if submarine warfare were to break out.

The announcement this month by the China Geological Survey puts pressure on other countries that have been ramping up their own seabed mining efforts, in part to reduce their dependence on China for critical minerals and rare earth elements.
Ocean sediments are rich in valuable resources including cobalt, nickel, and manganese.

“China is pouring enormous resources in an effort to emerge as a world-leading oceanographic power,” said Bruce Jones, a naval affairs and foreign policy expert at the Brookings Institution.
The United States historically dominated in ocean-science fields, he said.
Now, China is closing the gap, increasing China’s military capabilities and equipping it with the knowledge needed to fight underwater, Dr. Jones said.

With mapping of this nature, “you can use it for science, and you can use it for warfare,” Dr. Jones said.
“It’s a rare-earth play, it’s a scientific play, and it’s a strategic play all at once,” he said.

The atlas, according to materials published on the China Geological Survey website, maps the locations and concentrations of dozens of resources, drawing from two decades of research and samplings at more than 10,000 locations.
The China Geological Survey said the atlas included the East China Sea and the Yellow Sea, where China claims territory that neighboring nations consider theirs.

China controls most of the world’s supply of key critical metals and rare earths, which are essential ingredients in modern weapons and technologies, and the Chinese government recently approved a five-year plan that lists the development of deep-sea minerals a priority.
China has used its dominance to political ends, for example by restricting exports to the United States and Japan during disputes with those countries.

Japan is developing its own seabed mining program, in part to reduce its reliance on Chinese supplies.
In February, the government said it had successfully retrieved mud rich in rare earths from depths of more than 6,000 meters, an achievement that Japan’s prime minister, Sanae Takaichi, hailed as a “world’s first.” Japan and the United States have made commitments to support each others’ seabed mining projects.

The Trump administration has made seabed mining a priority.
It hopes to issue mining leases near Pacific Ocean territories like American Samoa.
It is also plans to permit commercial miningoutside of U.S. territorial waters without international approval.
China’s mining atlas has strategic importance in bolstering its claim for disputed waters, according to Yun Sun, who leads a Chinese foreign policy program at the Stimson Center, a foreign affairs research organization in Washington.
There are a number of international law customs that determine national boundaries.
Consistently occupying and managing a territory can strengthen a country’s claim to it.
That means nonmilitary actions, like science and conservation, can be used to exert authority over an area, Dr.
Sun said.
Publicly announcing the atlas could be interpreted as China making a statement that it commands this maritime domain.

Chinese deep-sea exploration ships have been spotted in the territorial waters of other countries, such as near the Aleutian Islands in Alaska.
China has also reportedly tested seabed mining equipment in waters that Taiwan and the Philippines claim.

Detailed mapping also helps countries claim additional seafloor, said Larry Mayer, director of the Center for Coastal and Ocean Mapping at the University of New Hampshire.
The United Nations Convention on the Law of the Sea sets a boundary of 200 nautical miles from a nation’s coastline as an “exclusive economic zone” where it has special rights over resources, but a country can claim more seabed if it can prove that its continental shelf extends beyond this zone.
This has been a significant driver of ocean exploration efforts, Dr.
Mayer said.
In 2023, the United States made public detailed maps made over the previous decade claiming about 380,000 square miles of expanded continental shelf, including in the Arctic, the Gulf of Mexico, and the Atlantic and Pacific Oceans.
China has also presented proposals to the United Nations to extend its claim to the continental shelf, based on geological map evidence, drawing borders that Japan disputes as overlapping with its exclusive economic zone.

In the South China Sea (which the atlas does not cover), China has redrawn boundaries in waters also claimed by Taiwan, Vietnam and the Philippines and has taken other steps, including building artificial islands, to support its claims.
Seabed mining is controversial.
Critics say not enough is known about deep-sea environments to safely mine them.
Research shows that mining would reduce the abundance of deep-sea animals and that ecosystems are slow to recover.
Numerous countries as well as environmental organizations have called for moratoriums or an industry ban.

Korea-Japan 'East Sea' dispute enters new phase as IHO adopts Digital Standard Society

From Seoul Economic Daily by Kim Do-yeon
 
The International Hydrographic Organization (IHO) has adopted a digital standard that identifies seas by unique numerical codes rather than names, a move expected to weaken Japan's long-standing claim to the sole use of "Sea of Japan."

According to the Ministry of Oceans and Fisheries on Wednesday, the IHO officially adopted the digital nautical chart dataset "S-130" at its Fourth Assembly held in Monaco from November 19 to 23.
The decision follows the organization's 2020 resolution at its Second Assembly to develop S-130 as a revised version of the existing nautical chart collection "Limits of Oceans and Seas (S-23)."

S-130 is a new digital nautical chart standard that identifies sea areas by unique identification numbers instead of names.
The key change is a shift from a name-based system to a numerical system suited for electronic navigation and geographic information systems (GIS).
Each sea area will be assigned a unique number combining the latitude and longitude of its center point, meaning seas will be managed under what amounts to an "identification number system."

"This is currently in its early stage, and after the IHO lays the groundwork, the system will be gradually refined to become operational," a Ministry of Oceans and Fisheries official said.
As a result, the existing standard nautical chart collection S-23 will remain only as a reference material from before the digital transition.
A map uploaded on the Voluntary Agency Network of Korea (VANK) website shows the body of water between Korea and Japan labeled as the East Sea.

The adoption of the new standard is also the result of the Korean government's continuous efforts to raise the issue and engage in diplomatic outreach in response to the sole designation of "Sea of Japan" in S-23.
Korea and Japan have long been in conflict over the naming of the sea area east of the Korean Peninsula.
When the IHO compiled S-23 in 1929, Japan registered the sea area as the "Sea of Japan," but Korea, then under Japanese colonial rule, was unable to participate in the naming process.

Since then, discussions have continued based on the principle of dual naming in the absence of agreement between the parties, but no consensus has been reached due to differences between the two countries.
However, with the introduction of S-130, sea names themselves will no longer be used in the future digital standard system, bringing the long-standing "East Sea dual naming" debate into a new phase.

Experts say the nature of the competition is fundamentally changing.
Under the previous S-23 system, the key question was which name to display.
Going forward, how a particular name is presented within the data structure has become the more important issue.

"The goal should now be to design a structure in which the East Sea is continuously exposed," said Park Chang-gun, a professor of Japanese Studies at the School of East Asian International Studies at Kookmin University.
"Rather than focusing on dual naming through diplomatic persuasion, the key task is to ensure that the East Sea naturally appears through data structures and standardization rules."

"We need to strengthen our capacity to participate in international standard governance in order to secure a position that can influence decision-making and design," Park added.
"Since the actual impact of place-name designation is determined on platforms such as Google Maps and marine information systems, cooperation with global platforms is also essential."

He also said, "We need to develop a strategy for taking the lead in standards and structures amid the low-intensity competition with Japan."

Strongest El Niño in a century? What this rare phenomenon could bring.

From WP by Ben Noll

This year’s potential super El Niño is looking increasingly likely to have wide-reaching climate impacts that last into 2027.

 The chances for a planet-warming super El Niño this year are rising, according to an updated model forecast issued Sunday.
The latest ECMWF outlook indicates there’s a high chance for a supercharged version of the climate pattern that affects regional-to-global weather patterns this summer or fall, doubling down on a super El Niño prediction from last month.

During a typical El Niño, a warming patch of water in the equatorial Pacific Ocean influences what regions experience droughts, floods, extreme heat, hurricanes and declining sea ice. During relatively rare super El Niño events, happening once every 10 to 15 years on average, the effects may be stronger, more persistent and more widespread.

That’s because sea temperatures in that key region of the Pacific Ocean warm more than 2 degrees Celsius (3.6 degrees Fahrenheit) above average, leading to a strong atmospheric response — typically peaking in December or January.

For example, the Western United States, parts of Africa, Europe and India could face a hotter-than-average summer, some tropical countries, such as those in the Caribbean and Indonesia could face worse drought and extreme heat, while more tropical cyclones could develop in the Pacific, with fewer in the Atlantic.
This possible super El Niño could also push global temperatures to record levels, particularly in 2027, and have agricultural impacts as weather patterns change.
“Real potential for the strongest El Niño event in 140 years,” wrote Paul Roundy, a professor of atmospheric science at the State University of New York at Albany.

Global impacts from a super El Niño
 
 SST anomalies

This year’s potential super El Niño seems increasingly likely to have wide-reaching climate impacts that last into 2027.

It could break the record for El Niño intensity set in December 2015, when sea temperatures in the central equatorial Pacific reached 2.8 degrees Celsius (5.04 degrees Fahrenheit) above average.
Still, even as some signs point to a potent event, including a rare triplet-cyclone pattern brewing in the Pacific, uncertainty remains as to how strong this year’s El Niño will become. Furthermore, no two El Niño events are alike — especially as the climate warms — but past experiences can be used to help plan and prepare.
Here are some of the weather impacts predicted to unfold through at least October, according to the newest model outlook.

 
El Niño will influence areas of drought and downpours across the planet later this year.
(Ben Noll/The Washington Post; data source: ECMWF)
  • Reduced hurricane activity in the Atlantic Ocean and possible drought in the Caribbean islands. Increased hurricane and typhoon risk in the Pacific Ocean, including Hawaii, Guam and much of eastern Asia.
  • Potential drought in central and northern India, suppressing rainfall from that region’s monsoon season, which could impact agricultural production.
  • Above-average summer temperatures and humidity in the Western United States, possibly coming with unusual downpours, which may reach into the Plains and extend severe thunderstorm season.
  • Developing droughts in portions of Central Africa, Australia, Indonesia, the Philippines, some South Pacific islands, Central America and northern Brazil, particularly later in the year. Flooding downpours in Peru and Ecuador, parts of northern and eastern Africa, the Middle East and near the equator in the Pacific.
  • Higher frequency of heat waves across large parts of South America, the southern United States, Africa, Europe, parts of the Middle East, India and eventually Australia.
  • New global temperature records — especially in 2027 — probably breaking records set in 2024.

(Ben Noll/The Washington Post; data source: ECMWF)

The strongest El Niño events almost always cause a record-warm year. That’s because heat comes out of the ocean during El Niño, overspreads the tropics in the Pacific, then gets redistributed across the planet by changes in the jet streams.
This could contribute to milder winter temperatures in the United States — and big storms along the West Coast — as the impacts of El Niño reach a peak from the end of the year into early 2027.

As the planet warms, El Niño behaves differently

Strong El Niño periods often appear as an upward stairstep in long-term plots of global temperatures.
“Due to the increasing concentration of greenhouse gases, the climate system cannot effectively exhaust the heat released in a major El Niño event before the next El Niño comes along and pushes the baseline upward again,” Defense Department meteorologist Eric Webb said.
Therefore, a super El Niño in 2026-27 would disperse more heat than other events in 1982-83, 1997-98 and 2015-16.

(Ben Noll/The Washington Post; data source: NOAA/OISST)

Not only would a super El Niño spread unusual heat and humidity far and wide, but it may also spark record atmospheric moisture flows-, which drive downpours that raise the risk for floods. That’s because a warmer atmosphere has a higher moisture-carrying capacity.
