Monthly Safety Scenario (MSS)

The Monthly Safety Scenario (MSS) is a Loss Prevention initiative to assist members in their efforts to comply with international safety regulations and to follow best practices.

The Club is publishing, every month, a new Monthly Safety Scenario (MSS) to assist owners in their efforts to comply with the above regulations. Alternative scenarios will be uploaded in SCOL. It is easy to download the MSS and enter the written conclusions from the meeting and send feedback to the shore-based organisation.

MSS Case November: Main engine failure caused serious contact accident

Crew on handheld radioIt was night and the vessel was in ballast condition and heading to port. The pilot boarded and two tugs were connected: one on the bow and one on the stern. Prior to the pilot boarding, the engine had been tested and the prearrival checks had been completed. At the pilot brief the pilot was given the pilot card and he informed the Master that the plan was to berth on the starboard side. To be able to do this the vessel was required to carry out a 180° turn to port. The Master had lined up the vessel and started to turn when the main engine failed to respond. He ordered slow astern but there was no response. Several repeated orders, from slow astern to full astern, were commanded from the bridge telegraph but with no response.

The main engine was a medium speed four-stroke engine driving a fixed pitch propeller through a gearbox controlled via a Woodward governor and reversing effected by the main gearbox. Control was carried out via the electronic bridge control.

On this vessel, during manoeuvring the Chief Engineer was customarily on the bridge. He was operating the engine telegraph and attempted to transfer control to the engine control room. At the same time the pilot requested the two assisting tugs to attempt to turn the vessel away from danger. Just in front of the vessel were a tug and a moored barge, which the vessel hit at a speed of five knots.

Under the ISM requirement, owners are obliged to carry out monthly safety meetings or safety committee meetings onboard their vessels. This obligation stems from Chapter 5 of the ISM Code: “Master’s responsibility and authority” and furthermore from “5.1.2, motivating the crew in the observation of that policy”.

The obligation can also be derived from the Code of “Safe Working Practices for Merchant Seamen”, where it is stated that the safety committee should meet regularly: “3.13.2, The frequency of meetings will be determined by circumstances but as a general guideline, the committee should meet about every 4-6 weeks”.
