ARCO King Salmon Platform; MacArthur River Field, Alaska

MacArthur River Field, Alaska | 1992-Apr-25

Initial Notification: A release of Cook Inlet crude occurred from the ARCO King Salmon Platform about 0845 on April 25, 1992. Apparently, the King Salmon Platform was draining its production separator and failed to equalize pressure, causing a skimmer tank to fill too quickly, thus resulting in a tank overflow of 8 to 10 barrels of crude oil. The overflow created a black slick approximately 400 by 100 feet. At the time of the incident, the weather was clear, the seas calm, and the winds light to nonexistent. Within an hour the Cook Inlet Spill Prevention and Response Inc. (CISPRI) was on the scene. The response ended on the evening of April 27. USCG district 17. Keyword: skimmers, sorbent boom.
