Who’s Driving That Tanker? New Polar Code For Sailing Emerges

Publication: NBC News   Date: August 23, 2014   View Article

A quarter-century after a drunk captain and his fatigued crew ran the Exxon Valdez onto a reef where it spilled 10.8 million gallons of crude oil into Alaska’s Prince William Sound, new rules are taking shape to prevent a similar disaster in the rapidly opening Arctic Ocean.

There, melting sea ice is opening a new frontier for cruise and cargo ships as well as prospectors for oil, gas, and hard rock minerals.

A key goal of the new rules is to ensure people skilled in navigating ice-strewn seas are aboard every vessel in Arctic and Antarctic waters, according to Lawson Brigham, a distinguished professor of geography and Arctic policy at the University of Alaska, Fairbanks, who has participated in the development of the so-called Polar Code for more than 20 years.

Giant Waves Pose New Risk for Ships in Ice-Diminished Arctic

Monster waves should be added to the list of hazards faced by ship captains as they plot a course through the waters of the Arctic Ocean, according to a new study that reports observations of house-sized swells in seas that until recently were covered in ice year-round.

“Waves always pose a risk to working at sea,” study author Jim Thomson, an oceanographer at the University of Washington in Seattle, said via email to NBC News from off the coast of northern Alaska. “The unique thing about the Arctic is that it is changing so rapidly that we cannot apply past measurements to understand future risk.”

Arctic Ship Traffic and Oil Spill Worries Rise as Ice Recedes

Ships packed with frozen mackerel and herring will sail in convoy behind a Russian nuclear-powered icebreaker from Norway to Asia this summer along the Northern Sea Route through the Arctic Ocean — a trial run as companies rush to capitalize on the world’s hunger for fish and to extract minerals from the top of the world.

Dozens of ships now transit the Arctic each year amid decreasing summer ice — in 2013,71 vessels plied the Northern Sea Route, including the first container ship. In another first, a bulk carrier transited coal through the famed Northwest Passage on a voyage from Vancouver, British Columbia, Canada, to Finland. And that traffic is only likelier to get busier.

Hundreds more ships “go up to the Arctic and perform some activity and then they come out,” Lawson Brigham, a professor of geography and Arctic policy at the University of Alaska, Fairbanks, explained to NBC News. Most of these ships transport equipment to mines and other industrial sites and leave with commodities such as oil, gas, copper, nickel, and iron ore.

Pacific Northwest’s Salish Sea Eyed as Fossil Fuel Gateway

Publication: National Geographic News   Date: May 9, 2014   View Article

Trains loaded with crude oil from North Dakota’s Bakken shale formation rumble past the outfield bleachers of the Seattle Mariners’ baseball stadium several times a week. From there, the trains head north, their cargo destined for multiple refineries in Washington State.

The traffic is new: Just three years ago, no oil trains were coming to Washington. Bakken crude is filling a void created by dwindling shipments from aging oil fields on Alaska’s North Slope, and the petroleum industry wants to bring in more. But the push to build more rail and shipping capacity in the Pacific Northwest is spurring debate over how that oil flow will affect the region—and where it should ultimately go.

The Next Exxon Valdez? Remote Alaskan Waters, Experts Fear

Publication: NBC News   Date: March 24, 2014   View Article

A quarter-century after 10.8 million gallons of crude oil gushed from the Exxon Valdez and scarred Alaska’s Prince William Sound, oil spill responders fear that another disaster looms in more remote Alaskan waters where ship traffic is on the rise, due in part to the North American energy boom.

The largest concern centers on the Arctic, where oil exploration and development is progressing in fits and starts, and Unimak Pass in the Aleutian Islands, a choke point on a major shipping route between North America and Asia. Both regions are expected to see increased traffic as summer sea ice disappears and producers of North American crude oil and coal look to export fossil fuels to Asia.

Global warming to open ‘crazy’ shipping routes across Arctic

By the middle of this century, thanks to climate change, anyone with a light icebreaker can spend their Septembers going anywhere they want in the Arctic Ocean, including straight over the North Pole, according to a new study.

Ordinary vessels, which account for more than 99 percent of shipping traffic, could easily navigate the Northern Sea Route along the Russian coastline and, in some years, even find a route through the fabled Northwest Passage.

“That’s kind of crazy and, frankly, a little bit worrisome,” Laurence C. Smith, a geographer and sea ice expert at the University of California, Los Angeles, told NBC News. “It is not like these will be open blue seas and safe or open year round.”

Blowing bubbles to make ships more fuel efficient

Publication: msnbc.com   Date: January 19, 2012   View Article

Blowing a lot of bubbles under cargo ships turns out to be a good way to cut down on fuel costs, according to ongoing research on so-called air lubrication technology.

“The basic idea is that if you could somehow have air close to the hull, it would help the hull slip through the water better by reducing the skin friction,” Steven Ceccio, a professor of naval architecture and mechanical engineering at the University of Michigan, explained to me Wednesday.
