Sinking of Offshore Supply Vessel Ricky B

Executive Summary

On May 30, 2013, at 0702 central daylight time, the offshore supply vessel Ricky B sank in the Gulf of Mexico about 24 nm south of Marsh Island, Louisiana, while being towed. The three crewmembers had abandoned the Ricky B earlier and boarded a good samaritan vessel, from which they were subsequently transferred to a nearby manned oil platform. No one was injured. The Ricky B was later refloated. Its damage was estimated to be $520,000.

Probable Cause

The National Transportation Safety Board determines that the probable cause of the sinking of the offshore supply vessel Ricky B was the crew's failure to adequately assess the severity of the flooding rate through the starboard shaft seal gland and take prudent action to mitigate the situation.
