Planning Oil Spill Response Tactics for Offshore Production Islands

Abstract

ABSTRACT In anticipation of the Beaufort Sea's first two offshore production islands, Alaska's North Slope oil producers recently expanded their oil spill recovery tactical plans and equipment. To seek regulatory approval for offshore oil production, industry responders joined agency regulators and made plans to clean up as much as 225,000 barrels of oil from potential blowouts over 15 days. Response technicians are configuring new and existing skimmers, vessels, and barges on the North Slope to implement those planning standards. This paper outlines the oil spill tactical plans and equipment that Alaska's North Slope oil industry recently assembled in seeking regulatory approval for the first offshore production islands in the Arctic. The operators of North America's largest oil fields are beginning the first production from oil wells separated from roads and most spill response vessels. For example, the new Badami production pad lies on the Arctic coast more than 25 miles from the Prudhoe Bay facilities, across river courses and roadless tundra. Eight miles of ice-infested sea will separate the proposed Northstar and Liberty production islands from response vessel berths. The new fields regularly experience waves, cold, and ice invasions that constrain oil recovery efforts. Yet regulatory approval to begin oil production requires that the industry have plans and equipment to clean up all the oil that may enter open water, even from the largest spills, within 72 hours.
