Having to work over the side while underway cannot be avoided at times but is always dangerous. The Nautical Institute issues this warning in its latest Mars Report, in which a crew member fell overboard while rigging the pilot ladder.

The Nautical Institute gathers reports of maritime accidents and near-misses. It then publishes these so-called Mars Reports (anonymously) to prevent other accidents from happening. A summary of this incident:

A bulk carrier in ballast was making way at 7 knots in a traffic separation scheme (TSS). The pilot ladder was being prepared on the port (lee) side by the chief officer along with the bosun and three other crew. As the vessel exceeded the 9-metre height criterion, the pilot ladder had to be rigged in conjunction with the accommodation ladder, located abreast of cargo hold number 4. Since it was dark, the overside floodlight was switched on to permit the crew on deck to work safely.

The pilot ladder was lowered over the ship’s side and the accommodation ladder was swung out and rigged. The bosun went down the accommodation ladder to the lower platform to lash the pilot ladder to the ship’s hull. The vessel was experiencing rough seas with winds gusting at 50 knots and a wave height of between 2 and 3 metres. There was reportedly no rolling or pitching, but the bosun was not wearing a lifejacket nor was he secured by a safety line.

He then returned to the main deck, collected another rope and again descended the accommodation ladder to fasten the ladder platform to the pilot ladder. Soon after, a loud yell was heard from below. The bosun was seen in the water and the man overboard (MOB) alarm was raised. It was now 01.45.

A lifebuoy with a self-igniting light was thrown overboard immediately. A second lifebuoy with light was also released. Upon hearing the MOB alert, the OOW rushed to the port bridge wing and released the bridge wing lifebuoy. He then pressed the event key on the ECDIS as a reference point (MOB) on the chart. Meanwhile, the master reduced speed, informed local vessel traffic services (VTS) on the VHF and requested permission to turn the vessel back for rescue operations.

The general alarm was sounded and an MOB was announced through the public address system. Lookouts were posted on each side of the vessel and the rest of the crew members were mustered at the muster station. By 02.00, the vessel was on a reciprocal course of the TSS. Three lighted buoys were sighted, but the crew members could not find the victim.

After some searching, the master made a request to VTS to arrange for local search and rescue units on scene and their vessel to return to an anchorage area so as not to hamper navigation of other vessels in the TSS. At 03.15, the local Coast Guard began search and rescue operations at the site of the MOB position. However, despite the rescue efforts of the Coast Guard, the victim was not found.

Advice from The Nautical Institute

  • Going down the accommodation ladder with neither life vest nor safety line must have been based on similar, past, successful operations, which may have never been challenged on board. This ”slippage” in safety is a pernicious and common phenomenon.
  • Always use your common sense to question current work practices. Just because the task has always been done a certain way does not mean it is safe. Working over the side while underway is particularly fraught with danger. Yet, mariners have little choice when rigging the pilot combination ladder. This task needs safety barriers such as wearing a safety harness and a life vest.
  • When there is an MOB situation, nothing is more important than finding the victim quickly. Other traffic in the area must give way, slow down or otherwise assist in the search.

Mars Reports

This accident was covered in the Mars Reports, originally published as Mars 202130, that are part of Report Number 344. A selection of this Report will also be published in SWZ|Maritime’s July-August 2021 issue. The Nautical Institute compiles these reports to help prevent maritime accidents. That is why they are also published 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.
