A hybrid retrofit installation, featuring an energy storage solution from the technology group Wärtsilä, will significantly enhance the efficiency and environmental performance of the ‘Harvey Energy’, a platform supply vessel (PSV). The vessel, which is owned by Louisiana-based Harvey Gulf International Marine, is the first LNG powered – and will be the first hybrid retrofitted – PSV in the Americas. The order was booked in April 2019. The Wärtsilä equipment is scheduled for delivery in December 2019.
The installation of a Wärtsilä 1450 kW battery hybrid solution will reduce the ship’s exhaust emissions, fuel consumption, and noise level. The overall fuel cost savings are expected to be in the range of 10 to 20%. 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.
“We chose Wärtsilä as our partner several years ago due to their significant experience in LNG and dual fuel engine technology, which fit very well with Harvey Gulf’s mission to have the most fuel efficient environmentally friendly fleet of platform supply vessels in the Americas,” said Shane Guidry, Chairman and CEO of Harvey Gulf. “In addition, Wärtsilä’s excellent knowledge of our business has resulted in very strong service support after the vessel delivery. This support has proven itself in zero unscheduled down time on the five LNG fueled PSVs in our fleet.”
Moreover, Wärtsilä’s integrated propulsion and cargo handling solution will deliver high efficiency for a new 30,000 cbm LNG vessel. The ship is being built at the Hyundai Mipo Dockyard (HMD) in South Korea on behalf of Norway based Knutsen OAS Shipping. The Wärtsilä solutions will ensure effective interfacing between the vessel’s propulsion, onboard auxiliary power generation, and cargo control processes. Such integration is essential in achieving full fuel-efficiency. The order with Wärtsilä was booked in January 2019, and the contract includes an option for an additional sister vessel.
