​Marine Accident Brief: Fire on Board Saturation Diving Support Vessel Ocean Patriot

Executive Summary

A fire that broke out in the forward machinery space of the saturation diving support vessel Ocean Patriot while under way in the Gulf of Mexico on the evening of November 28, 2013, was brought under control by the vessel's fixed fire suppression system without serious injury, and no pollution resulted from the accident. Damage to the Ocean Patriot was estimated to be $9.8 million.

Probable Cause

The National Transportation Safety Board determines that the probable cause of the fire on board the Ocean Patriot was damage to electrical cables due to the tightly installed metal securing bands in a cable tray chafing the protective layers of the cables and creating an ignition point. Contributing to the extensive damage was the combustible material stored immediately below the cable tray area, fueling the fire.
