The UK Marine Accident Investigation Branch (MAIB) issued the report of its investigation of a product carrier making heavy contact with mooring structures at a refinery on the River Thames on Feb. 25, 2008. While unmooring the vessel, the bow spring line was unexpectedly cast off. The pilot attempted to recover control of the vessel by laying alongside the next jetty, but the master (who was assisting) thought a different maneuver was being undertaken.
