New Orleans headquartered Harvey Gulf International Marine has selected Wärtsilä Energy Storage Systems (ESS) for the four further Harvey Energy class dual-fuel platform supply vessels it is to retrofit with batteries (see earlier story). A fifth vessel in this class was earlier fitted with a Wärtsilä ESS.
When the upgrade project is completed, all five vessels will be capable of full tri-fuel operation. The boats will be capable of closed bus dynamic positioning (DP) operation running only one engine augmented by the Wärtsilä Energy Storage System. When stationary in the field or in port, the boats will be able to operate on battery power only, thereby greatly reducing both fuel consumption and exhaust emissions.
“Wärtsilä is very pleased and proud to partner with Harvey Gulf in yet another ground-breaking project bringing technological advancement to the North American marine market. The combination of cutting edge technology, strong customer service, and Harvey Gulf’s market-leading business approach has resulted in a very successful partnership,” says Bill Amundsen, key account manager for Wärtsilä Marine Power.
“The conversion to tri-fuel technology is a tremendous addition to our already successful Harvey EnergY class PSV’s. Wärtsilä’s advanced technology and its unwavering commitment to service support were extremely important factors in our decision to select them for this project,” said Shane Guidry, Harvey Gulf president and CEO.
The four vessels, the Harvey Power, Harvey Liberty, Harvey Freedom, and Harvey America, will each be fitted with a Wärtsilä ESS comprising a closed bus-tie 1,360 kW drive with 746 kWh 1,100 VDC Batteries. The retrofitting project will be commenced in 2021 and will be completed in early 2022.
