Lighthouse Ship Management has seen one of its managed general cargo vessels enjoy a 33% reduction in fuel costs through a Berg Propulsion retrofit project.

The vessel, Terneskjaer, an 81-metre, 2,900 dwt general cargo ship owned by Bio Feeder AS, underwent a comprehensive upgrade to enhance energy efficiency. The Torangsvåg-based fleet manager evaluated various options for optimising energy consumption aboard Terneskjaer, which was built in 2008. The aim was to reduce fuel costs, lower emissions, and provide the vessel with a competitive edge in the marketplace.

After a consultative process, Lighthouse selected a retrofit package from Berg Propulsion to convert Terneskjaer to a more efficient diesel-electric propulsion system. The upgrade included the installation of a new gearbox, two permanent magnet motors, and the incorporation of Berg’s MPC800 control technology. Additionally, the existing Berg propeller blades were optimised to meet the vessel’s new operational requirements, with the addition of a nozzle designed to improve thrust, particularly at lower speeds.
