Louisiana-based Harvey Gulf International Marine has chosen Wärtsilä to supply an energy storage solution for the first platform supply vessel (PSV) hybrid retrofit in the Americas. The installation of a Wärtsilä 1,450kW battery hybrid solution will reduce the Harvey Energys exhaust emissions, fuel consumption and noise level. The overall fuel cost savings are expected to be in the range of 10-20%. The battery capacity will be sufficient to sail in and out of harbor on electric power. It will also provide hotel load electricity when docked, which will reduce noise and pollution levels in the harbor area. Furthermore, the ability to operate on battery power will improve maneuverability during critical dynamic positioning (DP) operations at offshore platforms. Included in the solution are the energy storage system, the energy management system, the transformer and drive, all mounted within a single container. The project will also include integration with the existing Wärtsilä power distribution, power management and integrated automation systems. The equipment is scheduled for delivery in December 2019.
