The French designer and manufacturer of battery technlogy, Saft, has won a major contract from Rolls Royce Marine to supply[ds_preview] the specialized marine lithium-ion (Seanergy) battery system for an innovative hybrid multi-application vessel under construction in Denmark for Kystverket, the Norwegian Coastal Administration (NCA). The high energy battery system onboard the »Bøkfjord« will help Kystverket meet its ambitious climate and environmental targets, reduce maintenance and make fuel savings of 25%, Saft stated. The multi-purpose workboat is under construction at the Hvide shipyard in Denmark, where it will be fitted with a Rolls Royce hybrid power system that includes diesel gensets and a Saft Li-ion Super Phosphate (SLFP) battery system integrated into the vessel’s automation and Power Management System. »Not only will the battery enable the ship to operate using only one diesel engine, but by smoothing out the peaks and troughs in demand the engine will also operate at its peak efficiency point. This offers the possibility for fuel savings of up to 25 %together with further operational savings resulting from the reduced requirement for maintenance of the gensets«, Saft said. The air-cooled battery system will have an energy storage capacity of 857 kWh, a nominal voltage of 647 V and a maximum voltage of 745 V.
