GE said that its electric propulsion technology was ‘selected for its low noise signature, high level of reliability and commonality with the Joint Support Ship (HNLMS Karel Doorman)’.
‘One of the customer’s key concerns is underwater radiated noise, meaning strict noise and vibration levels are imposed on the propulsion systems,’ said GE. ‘Pulse Width Modulation (PWM) voltage source inverters feed robust, high-torque density induction motors, allowing high-performance through the modern and optimised propulsion system.’
GE’s scope of supply includes the main switchboards for the ship distribution system, with two shore connection cubicles, the main electric propulsion system with two shaft lines of 7.9 MW each, as well as the associated power management and remote-control systems. The ship’s Energy Management System, which controls power generation and distribution systems, also supplied by GE, will ensure availability of electrical power in the ship network.
GE and DSNS aim to deliver the ship in June 2024. The CSS will be built by Damen in Romania, after which the ship’s combat management system will be installed in Den Helder, Netherlands.
