Bligh Reef Bligh Reef Bligh Reef, sometimes known as Bligh Island Reef, is a reef off the coast of Bligh Island in Prince William Sound, Alaska. This was the location of the 1989 "Exxon Valdez" oil spill. After the incident, US Code 33 § 2733 mandated the operation of an automated navigation light to prevent future collisions with the reef.

Bligh Reef is also where Alaska Steamship Company's Olympia ran aground in 1910. Bligh Reef serves as a fishing ground
Oil tanker but can be made from new-built hulls Shell España first used a tanker as an FPSO in August 1977. An example of a FSO that used to be an oil tanker is the "Knock Nevis". These units are usually moored to the seabed through a spread mooring system. A turret-style mooring system can be used in areas prone to severe weather. This turret system lets the unit rotate to minimize the effects of sea-swell and wind. Oil spills have devastating effects on the environment. Crude oil contains polycyclic aromatic hydrocarbons (PAHs) which are very difficult to clean up, and last
