Attached is the full NTSB report. Here’s what happened:
- In May 2024, the Baylor J. Tregre tugboat was towing a platform on the barge MARMAC 27 to Brazos Block 538 in the Gulf of America.
- The tug capsized in stormy conditions.
- The 4 crew members were rescued by the Coast Guard.
- The NTSB determined that the probable cause of the capsizing was “the mate’s inability to maneuver the tow into the wind due to the overwhelming towline force generated by the towed barge during the sudden onset of severe weather, resulting in unrecoverable heeling.”
Comments:
- Who knew? When a tugboat capsizes while towing a platform on a barge, endangering the crew, that’s a very serious incident. Yet there was no public announcement by the companies involved or the Coast Guard, and there was no media coverage following the incident (May 2024). The NTSB docket includes only the final investigation report.
- The NTSB report says a production platform was being towed, but it was actually a gas transmission platform owned by Transco Gas Pipe Line Co. There is no production in Brazos Area Block 538, an unleased block.
- Here and here are bits of information on the Transco’s Brazos Area 538 Platform modification project.
- Per a 2007 article, Williams’ Seahawk gathering system, which collects deepwater gas production, connects at Brazos Block 538 with a pipeline that transports gas to the Transco processing plant in Markham, TX (see map below).
- The NTSB report lacks context needed to understand the planning process, organizational factors, and timing/urgency of the project.
- The NTSB report attributes the failure to the mate’s inability to respond to the weather conditions, but provides no information on the safety management system, risk assessment, job safety job planning process, crew training, and other project management factors.
- Two of the crew members are suing Trinity Tugs alleging that they suffered personal injuries resulting from the negligence of Trinity and the unseaworthiness of the M/V BAYLOR J. TREGRE.
