U.S. offshore support vessel company Harvey Gulf International has ordered Wärtsilä's energy storage system for four of its platform supply vessels.
The upgrade included a Wärtsilä battery-power system on the PSV which was already a dual-fuel vessel capable of fully operating on LNG or diesel.
Now, the company will have five offshore vessels capable of full tri-fuel operation, providing Harvey Gulf with flexible and fuel-efficient PSVs for Gulf of Mexico operations.
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. The retrofitting project will start in 2021 and will be completed in early 2022.
