Concept
Exxon Valdez oil spill
Summary
The Exxon Valdez oil spill occurred in the Prince William Sound, Alaska, on March 24, 1989. Exxon Valdez, an oil supertanker owned by Exxon Shipping Company bound for Long Beach, California struck Prince William Sound's Bligh Reef, west of Tatitlek, Alaska at 12:04 a.m. and spilled (or 37,000 tonnes) of crude oil over the next few days.
The Exxon Valdez spill is the second largest in U.S. waters, after the 2010 Deepwater Horizon oil spill, in terms of volume of oil released. Prince William Sound's remote location, accessible only by helicopter, plane, or boat, made government and industry response efforts difficult and made existing response plans especially hard to implement. The region is a habitat for salmon, sea otters, seals, and seabirds. The oil, extracted from the Prudhoe Bay Oil Field, eventually affected of coastline, of which were heavily or moderately oiled.
Exxon Valdez was carrying of oil, of which approximately were spilled into the Prince William Sound.
The ship docked at the Valdez Marine Terminal at 11:30 p.m. on March 22, 1989. Loading of crude oil was completed late in the day on the 23rd. The tanker left the terminal at 9:12 p.m., March 23, 1989 (the deck log shows that it was clear of the dock at 9:21 p.m.), loaded with 53,094,510 gallons (1,264,155 barrels) of crude oil. Captain Joseph Hazelwood retired to his cabin at 9:25 p.m. Harbor pilot William Murphy and Third Mate Gregory Cousins were accompanied by a single tug for the passage through the Valdez Narrows – a journey of about 7 miles. The pilot left the bridge shortly after the vessel left the narrows, at 11:24 p.m. At this point, the captain was called to the bridge. Cousins helped the pilot disembark from the vessel, leaving the captain as the only officer on the bridge. At 11:25 p.m. Exxon Valdez reported that the pilot had left. The third mate advised traffic control and decided to deviate from the predetermined traffic lane to avoid small icebergs; a common occurrence since the Columbia Glacier calved such icebergs nearby.
