The three 173,400 cubic metres capacity LNG carriers will be Knutsens first with electric propulsion. They will be fitted with Converteams system based on induction motors and PWM type MV7000 converters, a statement said. The company didnt say how much the contract was worth.
The vessels will be of twin-skeg design and will be driven by two 13.6MW 570 rpm high torque density induction motors each fed by two dual PWM type MV7000 converters associated with an advanced digital propulsion control system.
Converteam said it would also supply the generators and the main and cargo MV switchboard.
Converteam is proud and enthusiastic about working with DSME and Knutsen OAS Shipping AS on this challenging project, Jean-Charles Duriaud, Director of the Marine Division at Converteam in France.
The first DSME-built vessel (Hull no. 2267) will be delivered to Knutsen on April 15, 2010, and the two remaining ships will be delivered later that year.
