The NTSB has published the results of its investigation into the sinking of the ITV Miss Roslyn. Following are the executive summary and probable cause as published on the NTSBs website. Below is a link to download the full report.
On October 9, 2018, at 1630 local time, the fleet towboat Miss Roslyn was traveling downbound at mile 142 on the Lower Mississippi River near Reserve, Louisiana, when it began to flood and list to starboard. The three crewmembers abandoned the towboat onto a moored fleet barge and a Good Samaritan vessel. The Miss Roslyn capsized and sank on its starboard side. No injuries were reported. There was a visible oil sheen; containment booms and absorbent pads were placed around the vessel. Damages from flooding were estimated at $1,130,000.
The National Transportation Safety Board determines that the probable cause of the capsizing of the Miss Roslyn was the company’s lack of effective hull inspection and maintenance program, which resulted in flooding into a steering void through multiple wastage holes in the hull.
