Poor bridge resource management and a charting error led to a bulk carrier striking an oil and gas production platform in the Gulf of Mexico, the National Transportation Safety Board said in Marine Investigation Report 22/18 released Tuesday.
The 24-person crew of the Ocean Princess was drifting overnight in the Gulf of Mexico before going to New Orleans to load a cargo of grain. The master planned to drift throughout the night with the engine on 15-minute standby, keeping clear of traffic and platforms.
