Collision of American Containership SS Sea-Land Venture and Danish Tanker M/T Nelly Maersk

Executive Summary


About 0340 c.d.t., on August 27, 1978, the American containership SS Sea-Land Venture collided with the Danish tankership M/T/ Nelly Maersk when the Sea-Land Venture attempted to overtake the Nelly Maersh in the Galveston-Houston Ship Channel. There were no injuries or deaths. Damage to the vessels was estimated at $1.4 million.

Probable Cause


The National Transportation Safety Board determines that the probable cause of the accident was the inaccurate evaluation of the closing rate and late initiation of the rudder order by the pilot of the Sea-Land Venture while attempting to overtake the Nelly Maersk at a bend in a narrow channel where the risk of collision was much greater than in a straight portion of the channel.​
