Tarbit Shipping, Sweden

Tarbit Shipping wanted to optimize its cargo operations as well as achieve economical operations in sailing. In addition, the vessels aimed to have PTI Take Me Home mode and PTI Boost mode. WE Tech chose The Switch PM shaft generator, which is driven by the main engine, to handle the cargo operations of the advanced LNG fueled tankers. In this mode, the propeller shaft is disconnected and the gas fueled main engine drives the shaft generator in variable speed.

A secondary power source for cargo handling will be shore power wherever available. The auxiliary generators will be used in cargo handling only as a third option. As the shaft generator also feeds the vessel with electrical power during sailing, auxiliary generators are only used in maneuvering mode and when the ship is idle and with no shore power available.
