During the drydock, a ship has to take shore power to ensure that al required electrical power will be met.
When the ship sits on the keel blocks in the drydock, Before the water reduce to sea water suction level the ship power should be transfer to shore power because the auxiliary engine-generators, which produce the electrical power, can no longer work due to non-supply of cooling water to the engine. To avoid overheating of moving parts of the engine, the auxiliary engine has to be switched off before the water is pumped out of the drydock.
The process of receiving shore supply is critical as unprotected connection may lead to accidents and wrong shore supply will hurt the efficiency and increase heat generation from onboard equipment.
Once all checks are performed by ship’s engineer and the ship is ready to take the shore power the change over can take place.
In this video we will show you the step by step process of changing over the electrical power from ship to shore while in Drydock.
