Despite being inside a breakwater, the changing direction of a storm caused significant problems for a small general cargo vessel resulting in the vessel breaking in two. The Nautical Institute describes the incident in a new Mars Report.
The Nautical Institute gathers reports of maritime accidents and near-misses. It then publishes these so-called Mars (Mariners’ Alerting and Reporting Scheme) Reports (anonymously) to prevent other accidents from happening. This is one of these reports.
A small general cargo vessel with a crew of thirteen arrived in ballast at its loading port and was sent to anchor outside the breakwater to await an available berth. Five days later, and still at anchor outside the breakwater, weather conditions were deteriorating. Strong onshore winds were expected, accompanied by high waves.
Because of its construction and freeboard, the vessel was limited by its Load Line and Class Certificate to “20 nautical miles offshore in the Black Sea”, and to maximum wave heights of 3.5 metres. The vessel’s master requested permission to seek more protected anchorage inside the harbour breakwater, and this was granted by the port authorities.
Days later, with the vessel now at anchor inside the breakwater, the weather deteriorated yet again with winds at over 50 knots. Although the anchorage site inside the breakwater protected the vessel at first, the storm shifted to the southwest, which caused waves to come through the breakwater entrance. The vessel was now exposed to heavy weather and sea conditions. Even with the assistance of the main engine, the vessel could not hold at anchor, and began to drag.
The master called for tug assistance, but due to the dangerous weather, the tugs could not leave their berths. It was now too late for a plan B. With the shifting winds and waves, the vessel was exposed to gales and very large waves. Suddenly, with the hull stressed beyond its limits, the vessel broke in two and drifted ashore. Thankfully, all thirteen crew were rescued.

Advice from The Nautical Institute
- Even within the confines of port, weather-related wind and waves can affect your anchorage or berth.
- Keep one step ahead of events by having your Plan B ready. In this case, and in retrospect, the only option was to have berthed before the storm.

Mars Reports
This accident was covered in the Mars Reports, originally published as Mars 202619. A selection of the Mars Reports are also published in the SWZ|Maritime magazine. The Nautical Institute compiles these reports to help prevent maritime accidents. That is why they are also published (in full) on SWZ|Maritime’s website.
More reports are needed to keep the scheme interesting and informative. All reports are read only by the Mars coordinator and are treated in the strictest confidence. To submit a report, please use the Mars report form.
