Oil companies in the Arctic : A rig too far

Putting the Chukchi Sea on ice, again

From The Economist

Shell’s retreat from the frozen north shows the new realities of “big oil”

Oil companies have a proud history of digging holes in inaccessible places and producing gushers of money.
But in the Chukchi Sea, in the Alaskan Arctic, Shell has poured $7 billion into a single 6,800-foot exploratory well, making it possibly the most expensive hole yet drilled, only to admit this week that it had not found enough oil and gas to make further exploration worthwhile.

That was a big climbdown for a company that had spent seven years since acquiring the Chukchi licenses in 2008 in a highly public, drawn-out battle to drill in the Arctic.
The decision boiled down to costs, financial and reputational.
Most big oil firms face similar pressures.
Some will take a lesson from Shell and put their Arctic plans on hold, though Eni, a big Italian oil firm, is vowing to press ahead with its efforts to drill in the Norwegian Arctic.

As the oil price has fallen by more than half over the past year, the economics of drilling in deep and treacherous waters have worsened considerably.
Though Shell had sought to play down the dangers of its Chukchi conquest, observers long ago reckoned it had bitten off more than it could chew.
It suffered a slew of mishaps in 2012, culminating on December 31st of that year in a drilling rig breaking loose from its tow lines and running aground.

  New marine tracking data shows MSV Fennica, a Shell-contracted icebreaker may have crossed through shallow waters that offered little clearance between the vessel’s bottom and the ocean floor before a 3-foot hole was discovered in its hull.

After that episode, Ben van Beurden, installed as Shell’s chief executive in 2014, could have halted the ill-fated project.
But after a “personal journey”, he decided to go ahead.
Since then, Shell has portrayed Arctic drilling as somewhat of a mission, saying the prospective hydrocarbon reserves—ten times the total produced so far in the North Sea—are needed to provide energy for a global population expected to rise from 7 billion to 9 billion by 2050.

Analysts say it was more about shoring up Shell’s reserve base, at a time when oil and gas deposits are increasingly held either by national oil companies or by nimble American “frackers”.
Last year Shell replaced only 26% of the 1.2 billion barrels of oil equivalent (boe) that it produced.
It has told investors that the Arctic was the best long-term bet for filling that gap, expecting it to provide at least 500m boe after 15 years.
Now it will need new alternatives.
If its £47 billion ($70 billion) takeover of BG Group, a British firm, goes ahead, that is one: it will increase Shell’s oil and gas reserves by a quarter.


 Shell in Beaufort and Chukchi Seas

Reputation was another factor in Shell’s retreat.
A company that was among the first oil majors to acknowledge the risk of human-induced global warming in the 1990s—and one that has joined with other European oil firms to advocate carbon pricing ahead of the climate-change talks in Paris later this year—was embarrassed to be pilloried for its Arctic drilling by environmental groups and politicians.
Just as serious were the concerns of Shell’s own shareholders.
Many of these, including some big pension funds, questioned its climate-change credentials at its annual meeting in May.

The stockmarket is taking the news in its stride.
But internally, the abandonment of the Arctic project will lead to soul-searching.
Shell is staffed more by boffins than roughnecks, who pride themselves on their ability to overcome great challenges with technology.
It has been in this predicament before.
In the early 1990s it gave up an earlier attempt to explore in the Chukchi Sea after prices tumbled.
Its decision to do so again, and big cutbacks by rival oil firms, may help crude prices eventually to recover.
But if one day Arctic oil and gas look promising once more, don’t expect much enthusiasm from Shell.

Sailing just got simpler with Assisted Sail Trim (AST)

AST is a very special topic: Sails metrics and computer assisted sails Trim.
Jeanneau’s exclusive ASSISTED SAIL TRIM technology delivers peace of mind and ease of handling This Jeanneau innovation, co-developed in partnership with Harken, allows to trim the sails and remotely operate the winches directly from a screen at the helm station.
Designed to ensure comfortable and easy sailing, the ASSISTED SAIL TRIM system is ideal for short-handed cruising.
100% user-friendly and intuitive, it brings numerous features to cruising in the same way as the autopilot does. 

 From Jeanneau

Jeanneau and Harken are glad to announce the launch of their exclusive innovation making sailing easier.
Result of a close collaboration between Jeanneau, leading sailboat producer, and Harken, specialized manufacturer and distributor of innovative sailboat hardware and accessories, the AST “Assisted Sail Trim” reinvents cruising and shorthanded sailing.



This collaboration has produced an advanced system to make sailing easier for families, cruisers, shorthanded crews, solo sailors, and those with limited mobility.

The system, consisting of three OEM packages, offers sensor-guided, push-button sail control.
  1. The Auto Tacking base package adjusts the headsail for the new tack while you steer through the maneuver. Sensors detect wind speed and apparent wind for safety.
  2. Auto Trim is the perfect complement to Auto Tacking for easy cruising. Set the initial trim, press the button to engage Auto Trim, and then let the system handle sheeting. The system monitors apparent wind for perfect trim while you relax at the helm. An integrated heel control detects gusts and limits heel to your desired setting for maximum passenger comfort.
  3. The Sail Management package, which will debut in coming seasons, can hoist and douse the main or genoa. Load sensors detect jams and allow the halyard to be eased for safe operation.
All functions, as well as push-button control over each winch, are operated from a cockpit display.
Harken Rewind™ winches or Captive Reel winches allow the system to both trim and ease without manual intervention.
All packages feature full redundancy and manual backup in the event of power loss.

Jeanneau will debut the Auto Tacking and Auto Trim packages on its Sun Odyssey range under the name Assisted Sail Trim (AST).
The AST will be exclusive to Jeanneau Sun Odyssey during the 2015 season.

“It’s been a challenge to keep this project secret through years of development and on-the-water testing, but this finely-tuned system was definitely worth the wait,” says Davide Burrini, Harken International OEM Sales Manager.
“By centralizing controls, integrating wind and equipment sensors, and allowing skippers to control all sheeting from the helm, this project has the potential to revolutionize cruising and shorthanded sailing.”

Erik Stromberg, Sailboat Product Director Jeanneau said, “This project has been a very unique collaboration.It has at times been difficult to tell where our Harken partners ended and we at Jeanneau began.The result is quite an elegant system, with room to grow its capabilities built right in. Our AST will give Jeanneau owners more of the relaxation they love about sailing, with less of the sail handling and adjustments that can sometimes intrude.”

Image of the week : Great Exuma Island, Bahamas from space

Amazing shot of Great Exuma Island, Bahamas from Space.
Image was taken by an astronaut of the Expedition 44 crew
(acquired July 15, 2015)

From NASA

An astronaut aboard the International Space Station took this photograph of small island cays in the Bahamas and the prominent tidal channels cutting between them.
For astronauts, this is one of the most recognizable points on the planet.

The string of cays—stretching 14.24 kilometers (8.9 miles) in this image—extends west from Great Exuma Island (just outside the image to the right).
Exuma is known for being remote from the bigger islands of The Bahamas, and it is rich with privately owned cays and with real pirate history (including Captain Kidd).

Small tidal changes on the banks cause great quantities of water to flow daily through the narrow channels between the cays, first in one direction and then the other.
The darker blue sections are the deepest parts of the channels, where the water flow has cut through the rock ridge that makes the line of cays.
The surrounding water is shallow (less than 25 meters, or 80 feet) and appears light blue.
Thanks to the astronaut’s steady hands in controlling a long lens in weightlessness, this photograph is detailed enough to show a single aircraft and its twin condensation trails.
