Loss of power supplies - emergency procedure for gas carriers

Loss of Power Supplies (including Emergency Power Supply)

Stop cargo operations. ESDS will be activated.

Inform the Master

Advise Terminal

Disconnect loading arms, if necessary. PERC. Consider - there are no means of controlling the moorings and, therefore, the vessel may move.

Monitor Tank pressure, consider - the possibility of venting

Evaluate situation (keeping in mind weather forecast for next few hours, proximity to shore) in order to determine the need for external assistance (Tugs).

Consider - leaving the berth

Consider - anchoring (inside port limits we will most probably be requested to have tug stand-by)

Hoist/exhibit signals: NUC (Not Under Command)

Use emergency radio to broadcast a warning to ships in the vicinity. Advise local Authorities (for example, VTIS if in Singapore strait)

Consider - emergency towing, make it ready

When Power has been Re-stored

Cancel warning to ships in the vicinity
Check gyro and steering device
Check navigation equipment
Check machinery
Check cargo equipment
Check all alarms
When power is restored, cancel the broadcast warning
Cancel external assistance if required (tugs)
Advise Terminal
Advise all parties concerned
