Wärtsilä Integrated LNG Propulsion System for Harvey Gulf PSV

Wärtsilä contracted for a complete (LNG) package, including propulsion, auxiliaries & controls, for a new OSV designed by STX Marine.

The ship has been ordered by Harvey Gulf International Marine as a part of the company’s ‘Going Green’ initiative. The vessel will operate in the Gulf of Mexico’s offshore oilfields.

Wärtsilä will supply the steerable thrusters, an Integrated Automation System, the Power Management System, a complete Low Loss Concept for the electrical distribution and drive architecture.  The vessel will be powered by 6-cylinder Wärtsilä 34DF dual-fuel generating sets capable of running on either LNG or conventional liquid fuels. The switch between fuels can be made seamlessly without loss of either power or speed. Wärtsilä will also supply the LNGPac , LNG bunkering , storage and supply system.

The switch to LNG propulsion is part of Harvey Gulf’s ‘Going Green’ initiative, aimed at reducing the environmental impact of the company’s vessels and operations. “These PSVs will be the cleanest burning vessels operating in the Gulf of Mexico,” says Chad Verret, Senior Vice President, Harvey Gulf International Marine. “Many permits for the eastern Gulf of Mexico already demand that operators use the best available capture technology with regard to particulates. In my opinion, the best available particulate matter capture technology is not to have any to start with, and that’s what burning LNG gives you,” he says.
