NTSB: Marine Accident Brief of the Capsizing of the Towboat Miss Roslyn

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.

Executive Summary
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.

Probable Cause
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.

USCG: Marine Safety Alert 13-19 Hazards of Retractable Pilot Houses on Towboats

12/06/2019 the USCG issued Marine Safety Alert 13-19 “An Important Safety Consideration – Hazards of Retractable Pilot Houses on Towboats.” The USCG has issued recommendations for reducing the risk associated with the crush hazard presented by the lowering of the pilot house.

EXCERPT FROM THE MARINE SAFETY ALERT:

The Coast Guard strongly recommends that towing vessel owners and operators that utilize retractable pilothouses:

  • Ensure pilothouses are installed with mechanisms capable of returning the pilothouse to a fail-safe locked condition in case of a failure or malfunction;
  • Ensure the pilothouses are equipped to sound an audible and visual alarm during all modes of pilothouse hydraulic movement;
  • Instruct operators to confirm personnel are clear of the danger zone before moving the pilothouse;
  • Instruct all personnel to never position themselves under the retractable pilothouse, even temporarily;
  • Clearly mark and place physical barriers around the perimeter of the pilothouse danger zone and discourage unauthorized personnel movement under the pilothouse;
  • Incorporate into the Towing Safety Management System (TSMS) the company/vessel’s policy and procedures, information about the potential dangers, audible and visual alarms, and safety considerations regarding operation of the pilothouses; and,
  • Ensure new crewmembers receive proper training regarding the dangers and that all personnel receive annual refresher training.

USCG: Maritime Commons – Towing Vessel Under Charter? Don’t Let it Cause a Break in the Safety System

The Coast Guard published Marine Safety Alert 12-19 to educate the towing vessel community of the need to maintain clear communication with all parties involved in their Towing Safety Management System (TSMS).

Recently, an investigation of a towing vessel loss of propulsion revealed gaps in the implementation of the vessel’s TSMS that were causal to the incident and a direct result of a poor TSMS-to-TSMS transition during the chartering of the vessel.

The ownership and operational management of a ship can be complicated. The common use of charter relationships among inland towing vessel operators, coupled with a potentially large number of involved parties (Coast Guard, Third Party Organizations (TPO), auditors, surveyors, owners, operators, etc.) and myriad documentation requirements (Certificate of Inspection, TSMS, surveys, audit reports, work lists, maintenance schedules, logs, etc.) makes this especially challenging.

In this case, an inspected towing vessel was chartered (bareboat) to another operator with a different TSMS. During the handoff to the new operator, the vessel was added to the chartering company’s TSMS. However, the handoff did NOT adequately address how to bring a chartered vessel under the new TSMS, the receiving TPO did not adequately survey the vessel, and the receiving operator did not understand the existing deficiencies or pending repairs/maintenance. During subsequent operations by the charterer, the vessel experienced a loss of propulsion due to insufficient fuel in the day tank. Upon inspection, the fuel transfer pump and the tank’s low- level alarm were both found inoperative. Only one of these issues (the low-level alarm) was known prior to the incident and that fact was not communicated during the vessel’s handoff. The investigation also revealed that the crew had no knowledge of the charterer’s TSMS procedures, did not feel empowered to conduct any repairs on the vessel and were generally unfamiliar with the vessel’s configuration and arrangement.

The Coast Guard strongly recommends that parties involved in the chartering of towing vessels complete the following actions prior to offering or accepting a charter arrangement:

  • Ensure a vessel is in full compliance with all applicable regulatory requirements;
  • Establish clear procedures to transfer a vessel to a different TSMS;
  • Confirm that all parties understand their responsibilities for safety, repairs, and maintenance;
  • Outline the steps to transfer known Corrective Action Reports, deficiencies, and maintenance needs;
  • Ensure planned and unplanned maintenance continues under the charter arrangement;
  • Establish processes to provide indoctrination/on-boarding for new crew members; and
  • Notify the Coast Guard to ensure proper updates are made to the vessel’s Certificate of Inspection.

In summary, each party in the Subchapter M ecosystem has a responsibility to ensure that the transfer of a vessel in or out of a charter does NOT become a break in safety processes or safety culture.
