Always double check that a valve is closed

UK MAIB report on Sea Breeze flooding and abandonment UK MAIB has issued accident report into the flooding and abandonment of general cargo ship Sea Breeze off Lizard Point, March 9th, 2014.The report reveals that a ballast pump in the vessel's engine room was being maintained when water began to enter the space. The crew were unable to stem the flow and the engine room was evacuated. The crew did not deal effectively with the emergency as they had not been trained.Salvors were able to bring the flooding under control and the vessel was initially anchored in St Austell bay at 2100 on 10 March before being moved to a berth in Fowey. The MAIB investigation identified a very poor standard of engineering being carried out on a ship in materially poor condition.The key safety issues identified:The master, who was the officer of watch at the time, was not aware that the work was taking place and no permit to work had been issued.A risk assessment had not been completed prior to work commencing, basic contingency preparations were not taken and good engineering practice was not applied.No on board training or drills had been completed, hampering the crew's ability to ...

Unsafe container removal results in crew fatality

Those involved in risky operations must ensure everyone stays alert The UK MAIB has issued itsSafety Digest including lessons learnt from maritime accidents. One case refers to a fatal accident during container removal.Containers were being discharged from inside the main vehicle deck of a ro-ro cargo ship. A crewman and a fork-lift truck driver were working together to move the containers from their storage positions onto trailers for transfer ashore. The crewman's job was twofold: to remove the twistlocks from the underside of containers before they were loaded onto trailers and also to remove twistlocks left behind on the deck to prevent them obstructing vehicles' tyres.Having lifted a 40 foot container from the top of another, the fork-lift driver moved his vehicle backwards and lowered the container. This improved the vehicle's stability but severely limited his visibility ahead. At the same time, the crewman moved forward to remove an underslung twistlock from the suspended container.Expecting the vehicle to continue its movement away from him, the crewman then turned round, facing away from the vehicle, and started removing redundant twistlocks from the deck. However, the fork-lift truck driver, who could not see the crewman, started to steer his vehicle to avoid ...

Lessons Learnt: Fresh water flooding large cargo ship

Lessons from UK MAIB's Marine Accident Reports The UK MAIB has issued the first issue of Safety Digest for this year including lessons learnt from maritime accidents. One case refers to poor planning and lack procedures which led to approximately 100 cubic metres of fresh water flooding accommodation and machinery compartments on board a large cargo ship.Due to the scheduled programme at the ships next port, a routine inspection of a fresh water storage tank was conducted on passage. The chief officer was responsible for the management of the fresh water and he delegated the task to the AB waterman. The waterman was told which tank to inspect and that the tank had been emptied. The waterman, who was familiar with the tank inspections on other ships, arranged for another crewman to assist. Neither crewman had inspected the water tanks on board.The two crewmen went to a compartment in the accommodation block where they thought that the tank lid was located. They then removed the lids securing nuts and one of the crewmen levered it out of position. As he did so, the tank lid was projected across thecompartment by the force of water coming from the tank below, narrowly ...

Keeping a high sided vessel alongside in strong winds

Lessons from UK MAIB's Marine Accident Reports The UK MAIB has issued its Safety Digest for this year including lessons learnt from maritime accidents.One case highlights the challenge of keeping a high sided vessel alongside in strong winds.The IncidentVessel 1:A large high sided ro-ro vessel was berthed alongside in strong winds at a busy European port. The master had decided to use four headlines, four stern lines, two forward spring lines and two aft spring lines to keep the vessel secure alongside during cargo operations, a decision he based on the weather forecast available at the time of arrival.The strong offshore winds were beam on to the vessel, causing significant loading on the vessels mooring lines. As cargo operations progressed the wind began to increase, and gust to 42 knots, which caused all four stern lines, the two aft spring lines and one forward spring line to part, and the stern to veer quickly off the berth. This caused damage to the stern ramp, and the vessel to swing across the river and ground on the opposite bank.The crew were able to close the stern ramp to prevent any further damage, and the main engine was started. Eventually, the vessel ...

Correct Tool is Key to Safe Maintenance

Lessons from UK MAIB's Marine Accident Reports The UK MAIB has issued its Safety Digest for this year including lessons learnt from maritime accidents. One case highlights how important is to always use the correct key for safe maintenance.The IncidentA ships engineer tested a spare fuel injector prior to use and found that the atomisation pressure regulating screw had been incorrectly set. The manufacturer had provided a clamping device to hold the injector, and a key to adjust the pressure regulating screw. To access the screw, it was necessary to remove a counter nut. The manufacturers tool for removing the counter nut was not held on board, therefore an ad hoc tool had been fabricated by ships staff.Despite his best efforts, the engineer was unable to loosen the counter nut with the ad hoc tool using the manufacturers clamping device. He then took the injector to the engine room workshop where he continued his efforts to release the counter nut with the injector secured in a vice. Again these efforts were unsuccessful as the tool constantly slipped out of the counter nut slot. After some consideration, the engineer thought he might be able to drill out the counter nut using ...
