Talking is not communication of the other person thinks you mean something other than what you do mean. Take this safety alert from Marine Safety Forum:
A PSV was carrying out a routine operation of loading fresh water at the quayside. During the bunkering process the duty AB reported that the water hose was showing signs of damage and was leaking heavily. The Officer on duty then stopped the water delivery, shut down the system and called the quayside requesting that the water men come and change out the hose.
After the hose was changed out and the duty AB tied up the hose in an effort to ensure that it would not get damaged against the ship’s hull. He then asked the waterman if ‘this is ok?’ meaning was the water man satisfied with how the hose was secured. The water man assumed that the AB meant that it was ‘ok’ to turn the water on again, which they did.
At the same time as the water men turned the water back on the AB called the bridge to inform the duty officer that the hose was connected and the water valves could be opened up again. Before the duty Officer had time to open the ships valves back pressure had built up in the hose on the quayside and caused the hose to part at the ’wire seizing’ collar connecting the hose to the camlock coupling between the hose joints on the quayside.
The hose parted with force causing the ‘ships end’ of the hose to whip on board and strike the AB on the chest area.
After the event the AB called the duty officer and advised him of his injury. The injury was assessed by the C.O. and the Captain; the AB was given pain killers and told to rest for a while. A further assessment would be carried out on his condition later in the day. The AB reported to the bridge a short time later and advised the Captain that he was feeling more pain. The Captain then arranged for the AB to be taken to hospital where he was assessed to have ‘one or possibly more’ broken ribs.
• The AB and C.O. on duty at the time of the incident were well experienced in PSV operations and considered bunkering of water to be a ‘routine task’.
• The water men who were on duty are also well experienced and had worked in their current positions for several years.
• There was no management of change, discussions / toolbox talks etc. undertaken between any parties on board or shoreside before or during the loading or while the hose change out operation was on-going.
• The crew were well experienced and considered shore side hose work to be a ‘routine task’ but a R/A should have been compiled and reviewed as and when required.
• The importance of management of change, discussions / toolbox talks / checklist completions etc. should be stressed to all involved. If in Doubt ’Stop the job’ and reassess.
• There should be a ’single point’ control for all bulking operation. (A common and proven practice on PSV’s is for the operation to be controlled from the bridge where the request is made via radio to the deck to open / close valves etc. The action is carried out and then confirmed back to the bridge before the next step is taken).
