Oil-drilling rig getting prepared for job in Arctic

Resurgence in exploration has Seattle shipyard busy

— During the past year, some 400 workers at a shipyard on Seattle’s Harbor Island have been installing new diesel engines, welding bulkheads, painting and tackling other tasks to prepare the Kulluk, a Shell Oil rig, for drilling holes this summer in the sea bottom off Alaska’s North Slope.

The refurbishing of Kulluk and other work being done in the Pacific Northwest by Shell has pumped some $200 million into the local economy, according to company officials. It could mark the start of a decade of exploration and development of offshore oil fields in Arctic waters.

“It’s the first new maritime-associated industry to start to emerge in Puget Sound in decades, and we’re just thrilled about it,” said John Lockwood, a senior adviser at Vigor Shipyards, which landed the oil-rig work at Harbor Island.

The push into the Arctic comes amid a resurgence of a U.S. oil industry that once appeared stuck in long-term decline. New technologies exploiting oil fields in North Dakota, Texas and other states have contributed to a 15 percent rise in U.S. production since 2008.

Producing oil in the offshore Arctic could provide another significant boost.

Federal estimates of the oil reserves in the Beaufort and Chukchi seas off Alaska’s North Slope indicate as many as 25 billion barrels, an amount greater than the crude produced at the Prudhoe Bay onshore field during the past 30 years.

But Shell’s initiative is stirring up an old fight over oil drilling in the Arctic.

Environmental organizations have repeatedly opposed Shell in court. Greenpeace has conducted a series of protests, and this summer is sending one of its protest ships, Esperanza, to monitor drilling.

Shell’s plans also have caused concern among the Inupiat Eskimos of Alaska’s North Slope, who have benefited from onshore oil development, but turn to the sea to hunt bow-head whales and other marine mammals.

Some residents are backing offshore exploration as a way to create jobs and a tax base to sustain the North Slope economy. Others oppose Shell.

“We are opposed to offshore development because the ocean is like our garden up here in the Arctic for our subsistence way of life,” said Tommy Olemaun, executive director of the Native Village of Barrow, Alaska, a tribal organization that is separate from the Barrow municipal government.

“The bow-head whale is the major food that we live off, and then there is the walrus, bearded seal and beluga.”

Shell first drilled in Arc-tic waters back in the 1980s, before abandoning its test holes during a period of low oil prices.

If the company embarks on a new round of development, Shell officials say production from the fields wouldn’t begin until 2023 at the earliest.

Shell’s preparations could include a 400-mile pipeline to carry Chukchi Sea oil across the North Slope to the trans-Alaska pipeline.

“We are not touting any kind of grand energy independence. This is all about energy choice,” said Pete Slaiby, a Shell Alaska vice president. He said offshore Arctic oil could help replace crude from regimes that the United States does not want to support.

The Kulluk and a second rig, the Noble Discoverer, are to leave Seattle later this month for the slow journey north. The rigs would begin drilling in July, when unusually heavy pack ice recedes enough to allow for summer work to begin.

Earlier this month, Slaiby gave a tour of the Kulluk to two enthusiastic boosters - Alaska’s Gov. Sean Parnell and U.S. Sen. Lisa Murkowski, both Republicans - who are eager for new sources of oil to help keep the trans-Alaska pipeline from being shut down because of a decline in production from onshore fields.

“We have a lot of potential on state lands. But in terms of what is happening right now, with actual dollars being invested in new exploration plays, this is it,” Parnell said.

Offshore exploration in remote Arctic waters has long been a contentious proposition.

The 2010 BP blowout and oil spill in the Gulf of Mexico undermined confidence in the oil industry’s ability to handle a big drilling disaster.

There also are increasing concerns in the scientific community about the impact of global warming - particularly in the Arctic - related to a buildup of greenhouse gases.

The Esperanza will monitor the Shell exploration and carry submarines to explore the sea bottom. Greenpeace has been ordered by an Alaska judge to stay at least five-eighths of a mile away from the Shell drilling rigs.

Environmentalists, pointing to the unsuccessful attempts to contain the 2010 spill in the Gulf of Mexico, say such a cleanup would be far more difficult in the harsh Arctic environment.

“Big Oil’s dismal spill record belies their continued assurance of safety,” said Michael Brune, executive director ofthe Sierra Club, in a statement earlier this year objecting to the Obama administration’s approval of Shell’s oil-spill response plan.

During the tour, Shell officials said drilling in the offshore Arctic area will be at much shallower water depths than in the Gulf of Mexico. Shell said Arctic drilling will be done at about 150 feet deep, compared with 5,000 feet deep in the spot where BP’s well blew out in the Gulf.

The wells also will tap into reservoirs that are under less pressure, reducing the risk of a major blowout, the company said.

Shell outfitted the Kulluk’s blowout preventer with a second set of shear rams that could shut down the well if the first preventer fails to do the job. Shell also engineered a backup cap-and-containment system similar to the one used to stop the BP blowout.

Should those systems fail, Shell will have oil-spill response vessels and other equipment stationed in the Arctic that, they say, could begin a cleanup.

To support the drilling effort, Shell will send nearly 20 vessels this summer to the Arctic in addition to the Kulluk and the Noble Discoverer.

The circular Kulluk, with a derrick that towers some 230 feet above the ocean’s surface, was built in the early 1980s. It drilled wells in the Canadian Beaufort Sea before being stored for years in shoreside ice. The refurbished Kulluk has new diesel engines and will house 108 crew members. The crew will work 12-hour shifts for three weeks running through the drilling season.

Shell’s work on the Kulluk and other preparations in the Pacific Northwest have created hundreds of shipyard jobs. Annual wages for such jobs at Vigor typically range from about $40,000 to $100,000 a year.

If Shell moves forward with development, the company would also have a need for production rigs and other equipment that Vigor might bid for, Lockwood said.

The Puget Sound region would also receive a boost as a transportation hub for pipeline and other supplies that would be shipped north to support the offshore oil fields. Other oil companies are expected to join Shell in drilling offshore wells.

Slaiby, however, says that a new maritime support industry for the offshore Arctic would not look anything like the sprawling facilities built in an earlier era to help sustain Gulf of Mexico drilling.

“There will be a smaller number of operators and a smaller footprint,” Slaiby said.
