Collision Between Offshore Supply Vessel Cheramie Bo-Truc No. 33 and US Coast Guard Cutter Harry Claiborne

What Happened

​On October 11, 2020, at 1544 local time, the offshore supply vessel Cheramie Bo Truc No. 33 was traveling with a crew of five outbound for sea in Sabine Pass when it collided with the US Coast Guard cutter Harry Claiborne, which was servicing a buoy near Texas Point, Texas. The Cheramie Bo-Truc No. 33 subsequently ran aground. The crew attempted to refloat the vessel, and as it broke free, the current set the offshore supply vessel into the stationary cutter, resulting in a second collision. Three of the 24 crewmembers aboard the Harry Claiborne suffered minor injuries; none of the Cheramie Bo Truc No. 33 crewmembers were injured. No pollution was reported. Total damage was estimated at $505,951 for the Cheramie Bo Truc No. 33 ($65,072) and the Harry Claiborne ($440,879).

What We Found

​The National Transportation Safety Board determines that the probable cause of the initial collision between the offshore supply vessel Cheramie Bo Truc No. 33 and the US Coast Guard cutter Harry Claiborne was the offshore supply vessel captain’s assumption of the stationary cutter’s position, which led to his decision to pass the vessel outside the channel, resulting in a late maneuver toward the Harry Claiborne to avoid running aground. Contributing to the collision was the cutter crew not questioning the passing arrangement proposed by the offshore supply vessel captain. Causing a second collision was the lack of coordination and communication between the two vessel operators when the offshore supply vessel crew refloated their vessel.​​​​
