Offshore Vessel Traffic Management Recommendations
Based on the West Coast Offshore Vessel Traffic Risk Management Project, which was co-sponsored 
by the Pacific States/British Columbia Oil Spill Task Force and U.S. Guard Pacific Area, it is 
recommended that, where no other traffic management areas exist such as Traffic Separation Schemes, 
Vessel Traffic Services, or recommended routes, vessels 300 gross tons or larger transiting along the 
coast anywhere between Cook Inlet and San Diego should voluntarily stay a minimum distance of 25 
nautical miles offshore. It is also recommended that tank ships laden with persistent petroleum products 
and transiting along the coast between Cook Inlet and San Diego should voluntarily stay a minimum 
distance of 50 nautical miles offshore. Vessels transiting short distances between adjacent ports should 
seek routing guidance as needed from the local Captain of the Port or VTS authority for that area. This 
recommendation is intended to reduce the potential for vessel groundings and resulting oil spills in the 
event of a vessel casualty.



WARNING
The prudent mariner will not rely soley on any single aid to navigation, particularly on
floating aids.  See U.S. Coast Guard Light List 
and U.S. Coast Pilot for details.
