Lessons from UK MAIB's Marine Accident Reports The UK MAIB has recently issued the firstSafety Digest for this year which includes lessons learnt from maritime accidents. One case refers to over-speed damage and highlights how important planned maintenance schedules on critical equipment are.Over Speed DamageFollowing a main engine overhaul on board a dredger, the engine was started for a trial run. After the initial start, the engines speed gradually increased over its normal operating limit. None of the over-speed protection devices, or the operation of the mechanical emergency stop, stopped the engine, which was eventually shut down by covering its air intakes and starving the engine of air. No secondary damage was apparent but two defects, which could have contributed to the over speeding of the engine and the failure to shut down the engine, were rectified. The engine was then tested but the test run did not include the operation of the engines protection devices.A few weeks later, the dredger was stopped while on passage to enable a fractured high pressure fuel line on its main engine to be repaired. Once the repair had been completed, the engine was re-started, but its speed again quickly increased beyond normal operating ...

Lessons from UK MAIB's Marine Accident Reports The UK MAIB has recently issued the first Safety Digest for this year which includes lessons learnt from maritime accidents.One case draws the attention on checking the passage plan without rely only on ECDIS and ensuring that navigational equipment is effectiveThe AccidentOn a calm and clear night a modern, well equipped tanker was heading through a busy coastal traffic separation scheme. To the OOW and lookout, everything on the bridge seemed normal. The OOW was sitting in the bridge chair, where he could see the radar display and the ship's ECDIS. He was following the route shown on the ECDIS display and he adjusted the ship's heading whenever necessary to keep on track.Unexpectedly, the ship's speed reduced to zero and soon afterwards an engineering alarm sounded. Assessing that there was a problem with propulsion, the OOW phoned the second engineer and asked him to check the engines.The second engineer called the bridge back and confirmed that power was available on the starboard engine, so the OOW applied power using the starboard control lever. But the ship still did not move. The OOW also called the captain to explain that propulsion had failed in ...

Lessons from UK MAIB's Marine Accident Reports The UK MAIB has recently issued the firstSafety Digest for this year which includes lessons learnt from maritime accidents.One case refers to a lifeboat accident due to badly timed tackle.The master of a cargo vessel had instructed the chief officer to complete the 3-monthly routines on the ship's lifeboats and fast rescue craft. The routines included lowering the boats to the water and releasing them from the davit falls. A team of two officers and two seamen was assigned the task of launching the boats. The lifeboats were of the fully enclosed type and required a minimum of three people on the boat: the officer in charge (OIC) and the two seamen to conduct the drill.To launch the boat, the bowsing tackle needed to be released, which allowed the boat to hang free in the davit prior to being lowered. This particular boat had band type bowsing tackles; it was important that these were released simultaneously in order that the boat swung smoothly into the lowering position. The OIC confirmed that both seamen were confident in operating the bowsing tackles before ordering the tackles to be eased off. The after tackle began to ...
