Marine Safety Forum – Safety Flash 13-35
Subject: Water Hose Near Miss
party water service company was tasked with supplying 75 tonne of water to a vessel berthed
on the quayside. The water service company connected the hose and on approval from the vessel
AB, switched on the water supply. Periodic checks were made by the water service company
between working a different vessel berthed further down the quayside. Approximately an hour into
the task, the vessel AB noticed the tank was close to overflowing so attempted to close the valve
on the quayside at point (A). Due to the AB not knowing the position of the water shut off valve
(point B), the AB disconnected the hose from the connection (point A) which was under 3 bar of
pressure at the time. The pressurised hose parted from the connection causing the water meter to
disconnect into the harbour narrowly missing the vessel AB.
What went wrong?
Inadequate warning / safety devices – Pressurised water connections were easily
accessible to vessel AB.
Inadequate Information – Vessel AB was new to the job and was unaware of the position of
the quayside shut off valves.
Operating Equipment without Authority – The Vessel AB attempted to shut of valve
without the authority / supervision of the water service company.
Failure to Recognize Hazardous Conditions –Vessel AB failed to recognise hazards with
disconnecting a pressurised system. Water Service Company failed to recognise the
hazards of leaving the task unattended.
Inadequate Planning – Toolbox talk was not carried out between water Service Company
Planning Water Service Company to implement toolbox talk procedure with vessels prior to
work commencing which will indicate responsibilities during water call - off operations. All
parties to sign when responsibilities understood.
Planning / information - Vessel packs updated with location of shut of valves on the
Safety devices – Water shut-off valve to be relocated to beside the connection point.
Safety devices – Water connection housing to be locked during operations to prevent
unauthorised personnel from disconnecting the water hose. Water Service Company to
manage key control.
Loading – operation supervised by a Deck Officer.
