Has information been exchanged between ship and shore on maximum/minimum temperatures/pressures of the cargo to be handled?
Before operations commence, information should be exchanged between ship and shore representatives on cargo temperature/pressure requirements.
This information should be agreed in writing.
Are cargo tanks protected against inadvertent overfilling at all times while any cargo operations are in progress?
Automatic shut-down systems are normally designed to shut the liquid valves and, if discharging, to trip the cargo pumps, should the liquid level in any tank rise above the maximum permitted level. This level must be accurately set and the operation of the device tested at regular intervals.
If ship and shore shut-down systems are to be inter-connected, then, their operation must be checked before cargo transfer begins.
Is the compressor room properly ventilated, the electrical motor room properly pressurised and is the alarm system working?
Fans should be run for at least 10 minutes before cargo operations commence and then continuously during cargo operations.
Audible and visual alarms, provided at airlocks associated with compressor/motor rooms, should be regularly tested.
Are cargo tank relief valves set correctly and actual relief valve settings clearly and visibly displayed?
In cases where cargo tanks are permitted to have more than one relief valve setting, it should be verified that the relief valve is set as required by the cargo to be handled and that the actual setting of the relief valve is clearly and visibly displayed on board the ship. Relief valve settings should be recorded on the check list.
Furthermore, the high pressure alarms should be set according to the relief valve setting.

Port:............................................................
Dear Sir,
Responsibility for the safe conduct of operations whilst your ship is at this terminal rests jointly with you, as master of the ship, and with the responsible terminal representative. We wish, therefore, before operations start, to seek your full cooperation and understanding on the safety requirements set out in the Ship/Shore Safety Check List which are based on safe practices widely accepted by the gas industry and by the gas carrier owners.
|
|
|
We expect you, and all under your command, to adhere strictly to these requirements throughout your stay alongside this terminal and we, for our part, will ensure that our personnel do likewise, and co-operate fully with you in the mutual interest of safe and efficient operations.
Before the start of operations, and from time to time thereafter, for our mutual safety, a member of the terminal staff, where appropriate together with a responsible officer, will make a routine inspection of your ship to ensure that the questions on the Ship/ Shore Safety Check List can be answered in the affirmative. Where corrective action is needed we will not agree to operations commencing or, should they have been started, will require them to be stopped.
Similarly, if you consider safety is endangered by any action on the part of our staff or by any equipment under our control you should demand immediate cessation of operations .
THERE CAN BE NO COMPROMISE WITH SAFETY.
Please acknowledge receipt of this letter by countersigning and returning the attached copy.
