Harvey Gulf LNG powered offshore support vessel

North America's LNG offshore fleet

The first and only U.S. operator to own and operate offshore support vessels powered by liquefied natural gas — with integrated bunkering at Port Fourchon.

As the first and only company in North America to operate offshore support vessels powered by liquefied natural gas (LNG), we stand behind our commitment to sustainability. LNG as a marine fuel allows for a reduction of carbon dioxide emissions up to 26% over conventional fuels, and it eliminates up to 99% of nitrogen oxides, sulfur oxides and particulate matter — the three primary industry pollutants.

We're proud of our efforts to lead by example, but we know more work needs to be done to address our industry's impacts on the environment and the communities where we live and work. That's why in 2020 we launched the first tri-fuel platform support vessel, which operates on battery power backed by LNG and diesel. By the end of 2022, all our LNG vessels were battery powered.

ENVIRO+

Green Passport Certification by the ABS

In addition to being powered by cleaner burning natural gas, the vessels will achieve ENVIRO+ Green Passport Certification by the ABS. The requirements for this certification include, among others, that the vessels be continuously manned with a certified Environmental Officer, be completely constructed with certified environmentally friendly materials, and have advanced alarms for fuel tanks and containment systems.

Along with Harvey Gulf's other vessels under construction, they will be the first OSVs to achieve this certification, making them the most environmental friendly OSV's in the Gulf of America.

Harvey Gulf continues its commitment to environmental protection by becoming the first to build a U.S. flagged vessel that can run entirely on natural gas. These vessels will meet the highest emissions standards that exist today and even higher standards that haven't been created yet. Harvey Gulf recognizes the strong stance on environmental protection by the administration in the wake of the oil spill and are doing our part to respond to it and provide our customers support for their environmental commitments.

North America's first LNG marine fueling facility

In 2015, Harvey Gulf completed construction of the first LNG marine fueling facility in the North Americas, which is located at its dock facility in Port Fourchon, Louisiana. This technologically advanced, environmentally safe clean energy facility is a critical component to the growing LNG supply infrastructure, supporting key operations of the oil and gas industry's offshore vessel fleet. Expanding on its commitment to safety and security of vessel operations and port facilities, Harvey Gulf actively enlisted the expertise of the United States Coast Guard to participate at all levels of the development and construction of this facility.

The facility consists of 270,000 gallons of LNG storage capacity, encompassed within three stainless steel type C pressure vessels with vacuum insulation and carbon steel exteriors. The facility can transfer 550 gallons of LNG per minute and, aside from its primary role of supporting the offshore oil and gas industry, is capable of supporting over-the-road vehicles that operate on LNG. Over the last six years, Harvey Gulf has successfully completed more than 1,000 LNG transfers and/or bunkerings, transferring over 20 million gallons of LNG, and is widely considered the pioneer in North America regarding LNG bunkering.

Harvey Gulf is focused on remaining an industry leader in the nation's growth toward LNG and cleaner burning fuels. The Company's dual fuel LNG vessels exceed the highest emission standards in the industry today, and our LNG fueling facility further solidifies Harvey's commitment to develop and use the safest, most environmentally friendly vessels and fuel technology available today.
