ALAMEDA (CBS SF) – Revelations that Osama bin Laden considered hijacking and blowing up U.S. oil tankers in order to provoke an “extreme economic crisis” came as no surprise to the Coast Guard in the Bay Area.

“This is something that security planners have obviously thought of and planned for since 9/11 and frankly before 9/11,” said Dan Dewell, spokesman for the 11th Coast Guard District based in Alameda.

Nevertheless the FBI and Department of Homeland Security issued a confidential warning to police and the energy industry the same day. Dewell said the Coast Guard would make no changes in the San Francisco Bay because of the newly disclosed intelligence.

Oil tankers regularly pass through the Golden Gate because of the ConocoPhillips, Shell and Tesoro refineries in Contra Costa County. Dewell said the Coast Guard regularly educates industry about improvements to protect ships.
