Synopsis of the incident:
Vessel arrived at Merak, Indonesia on End Dec 2010 at
1148 lt and berthed Dover terminal at 14:36LT on the
same day to discharge the charterer’s cargo.
Subsequently the weather has deteriorated and vessel
encountered gusty winds with heavy swell. The attempt
to un berth the vessel was unsuccessful in rough
weather condition. Eventually two forward mooring ropes
were parted as vessel was surging against the shore
fenders. One shore fender was damaged and vessel

Damage to Ship:

Causal factors:
• Terminal design less than adequate. No break water to
protect the ships from seasonal rough weather.
• Port logistics was less than adequate (In adequate
supply of powerful tugs upon request).
• Compliance to port information and guidance provided
to ship by the company was less than adequate

Lessons Learned:
• Obtain weather forecast prior berthing and closely
monitor while alongside. Un berth if necessary in
advance rather than waiting for last minute.
• Keep additional mooring ropes standby. Double up
moorings if vessel require to stay alongside during bad
weather & in case unable to un berth in time.
• Liaise with agent, vessel’s operator effectively to
ensure prompt assistance, support from shore.
• Master shall request operator to supply additional
stand by tug when deemed necessary.
