At 4 a.m. on March 15, 2019, the Dixie Vandal was pushing a partially loaded fuel barge upbound through the Houston Ship Channel when it veered off course and struck the moored barge Kirby and its 1,400-hp towboat Trinity. The cause? Fatigue. The pilot had been on watch for 10 hours of his 12-hour shift and did not recall making the course change before falling asleep. There were no injuries. Damages came to $630,230. The Dixie Vandal accident was recounted in the NTSB Safer Seas Digest 2020 along with two other fatigue-related accidents. Fatigue, which impact: decision-making, reaction time and comprehension, has been a longstanding issue in the commercial marine sector. The accident highlighted a potential weak spot in any vessel. It's the individual in the wheelhouse, charged with maintaining a constant situational awareness of the vessel and everything around it. Autonomous vessels, with integrated control systems and sensors, don't get fatigued and have long held the promise of more efficient and safer navigation and fewer accidents. |
