The Switch received a PM shaft generator order with an option of one more from the energy-efficient solution provider WE Tech for an LNG carrier owned by Saga LNG Shipping Pte. Ltd. Deliveries will commence in October 2016.
The Switch’s PM shaft generator operates over the full main engine speed range while generating electricity for the vessel’s electrical network with high efficiency. This feature is particularly advantageous in electrical part loads, which is the normal electrical load condition in any ship.
Along with The Switch PM shaft generator and WE Drive™, WE Tech will also deliver its efficient power distribution solution that provides the vessel’s electrical network with up to 1200 kW of electrical power in Power Take Out (PTO) mode. The delivery also features the Power Take In (PTI) mode for Take Me Home, whereby the WE Drive™ is used as an auxiliary propulsion drive when the main engine is not in operation. Furthermore, the solution utilizes the common DC-link in the WE Drive™ to enable energy-efficient DC power distribution for the bow thruster.
The high-speed PMM 500 marine shaft generator will be connected to the PTO shaft of the reduction gear in the propulsion line. The Switch offers PMM 500 shaft generators in various power ranges from 0.5 to 4 MW at speeds of up to 2,000 rpm to best adapt to various requirements.
