Alyeska Pipeline spends over $60 million annually for oil spill prevention and response in Prince William Sound, and has dedicated over 300 personnel to this effort, mostly through its Ship Escort/Response Vessel System (SERVS).
Created in July 1989, SERVS is considered one of the best oil spill prevention and response forces in the world. The SERVS mission is three fold: prevention, preparation, and response. Each laden tanker is escorted through Prince William Sound to the Gulf of Alaska by response vessels capable of assisting a distressed tanker. Oil spill response equipment has been pre-stationed throughout the Sound for rapid response.
