On January 15, 1978, the U.S. tankship SEALIFT CHINA SEA rammed amidships into the Italian vessel LORENZO D'AMICO which was moored. The CHINA SEA's engine control system was inoperative, and hand signals were being used to relay orders for the controllable-pitch propeller. The pilot's orders of half and full astern were mistakenly applied as half and full ahead, and the CHINA SEA rammed the LORENZO D'AMICO at a 90 degree angle at a speed of 3 to 4 kns. The CHINA SEA was slightly damaged, and the LORENZO D'AMICO was damaged beyond economical repair. No injuries or deaths resulted. The National Transportation Safety Board determines that the probable cause of this accident was the misinterpretation of the hand signals used to relay engine orders from the engine control room to the local control station for the controllable-pitch propeller, which resulted in wrong direction thrust. Contributing to the accident were the inadequate design of the engine control system, which failed to provide independent functioning of the propeller pitch direction indicators; the inadequate measures used to maintain, repair, and provide spare parts for the engine control system; the lack of an installed, reliable method to transmit engine orders to the local control station; and the inadequate telephone system between the engine control room and the local control station.
