Studies have concluded that oil platforms in the North Sea attract fish, and that a rigs-to-reefs policy there would benefit fishermen. However, the highly publicized occupation of the Brent Spar North Sea oil platform by Greenpeace in 1995 has been highly influential in Europe. Despite scientific findings of the potential value of rigs-to-reefs in the North Sea, the Oslo-Paris Commission (OSPAR), which has jurisdiction over North Sea oil development, has blocked rigs-to-reefs.
