First U.S. Flagged OSV Equipped with a Battery/Converter System

MBF member ABS was selected to class two Offshore Supply Vessels (OSV) being retrofitted with a battery/converter system by Harvey Gulf International Marine. MBF member, Wärtsilä, was contracted to supply the energy storage system, energy management system, transformer and drive.

The Harvey Energy will become the first ABS-classed dual-fuel (LNG/marine diesel) and battery vessel and the first U.S. flagged OSV equipped with a battery/converter system. ABS supported the integration of the lithium-ion battery into the hybrid power systems aboard the vessel, Harvey Energy.

The Wärtsilä 1450 kW battery hybrid solution, with the ABS class notation ESS-LiBATTERY, was installed. Reportedly, the installation enhanced efficiency and environmental performance, seeing in excess of 20 percent fuel savings, as well as major reductions in carbon emissions.
