(In)accessible for maintenance “Layout of the ballast valves; some are placed in a very ridiculous spot that maintaining it would be next to impossible. There is not enough room to manoeuvre so you’ll have to resort to acrobatics. There was this problem on one ballast valves inside the duck keel. They planned the replacement of the valves and went inside. Upon seeing the location of where the valve is, they put chain blocks, lashings and levers just to move the valve from the tight spot while doing their acrobatics. One seafarer lost his handle on one pipe that supported his balance and suffered multiple hits. His head hit the other pipe, his knee hit the frame and his elbow hit the bulkhead. ” please Please insert your company logo on the logo master here slide Cy. Cla.

Similar Windlass and Steering motor switches A narrow miss – A new AB went to switch on the windlass. Instead of switching it on, he switched off the steering motor. The vessel suddenly lost power started to move to starboard while approaching a port. There were no alarms on the bridge or engine room. Shortly the power came back and it was learned that the Bosun had told the AB that there was no power and the AB had realised what he had done and switched on the steering motor. please Please insert your company logo on the logo master here slide Cy.

Narrow, unsuitable piping system: oil spill The operator from the port lost patience with the delay in draining the long arm, that he disconnected before all of the oil had been completely drained which resulted in an oil spill on the deck. Design angle: narrow and unsuitable piping system requiring constant switching of pumps. The design issue had been brought to the attention of the company who were delaying fixing it but after the oil spill incident, retrofitted three ships of the same class. please Please insert your company logo on the logo master here slide Cy.

Ballast pump damage During deballasting, sometimes some tanks are empty, and an operator forgot that, the ballast pump was a centrifugal pump and it keeps running so that it actually brings cavitation and breaks the pump. Design angle: There should be an auto-cut off to save the pump in case of low pressure. please Please insert your company logo on the logo master here slide Cy. Cla.

Lifeboat fatality During lowering of a free fall lifeboat, one clamp opened and the other didn’t, leading to a fatality due the impact.

(Un)fit for purpose “I have been a pilot for 26 years, so I saw different types of VHF, radar, autopilot etc. 2 -3 times per working day. In the past I have kept lists of what was particularly good and particularly bad on bridges, I am sorry that I don’t have these anymore. Examples: radar with 125 buttons, radar with important settings hidden far away in menu structures, VHF automatically switching to 16, VHF needing ‘enter’ without indicating in any way, radars and VHF not near one another. In all kind of equipment cryptic indications (e. g. to find received messages on an AIS you had to open the “send message” menu. What to think of a GPS Receiver where the dimmer button was also the on/off button (short push: dimmer, long push - off…). How many examples are needed to demonstrate that much of the equipment is not fit for purpose at all……? ” please Please insert your company logo on the logo master here slide Cy. Cla.
