Harvey Gulf LNG-powered supply vessels to undergo Wärtsilä Energy Storage retrofit

20 Oct 2020

Maritime technology group Wärtsilä on Monday (19 October) said it will supply its advanced Energy Storage System (ESS) for retrofitting on board four Harvey Energy class LNG-fuelled Platform Supply Vessels (PSVs).

The retrofitting project will commence in 2021 and will be completed in early 2022.

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 1360Kw Drive with 746 kWh 1100 VDC Batteries.  

When the upgrade project is completed, all five vessels will be capable of full tri-fuel operation, thus providing Harvey Gulf with the most flexible, fuel efficient class of PSVs in the Gulf of Mexico. 

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,” said Bill Amundsen, Key Account Manager for Wärtsilä Marine Power.

“The combination of cutting-edge technology, strong customer service, and Harvey Gulf’s market-leading business approach has resulted in a very successful partnership.”

“The conversion to tri-fuel technology is a tremendous addition to our already successful Harvey Energy class PSV’s,” added Shane Guidry, Harvey Gulf President and CEO.

“Wärtsilä’s advanced technology and its unwavering commitment to service support were extremely important factors in our decision to select them for this project.”
