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 will be battery powered.

2021 ESG Report Cover


When we started down this course at Harvey Gulf, we weren’t following anyone else or picking a sustainable direction because it was a popular choice — it was simply a sound business decision. But after we saw the impact of our efforts, both economically and environmentally, we have fully embraced sustainability. We are setting the course for our company and industry on an ESG journey, maintaining excellence for our customers, our people and the environment. We are a vessel for change.

Mapping Our ESG Progress





As a pioneer in using LNG, we’re committed to reducing our environmental impacts. We’re proud to be the first company to receive the Enviro+ Green Passport Certification from the American Bureau of Shipping and to launch a tri-fueled vessel, which runs on battery, LNG and diesel. Now we’re taking steps to better understand our footprint and how we can lead our industry toward impact reduction.


Our employees are our most important resource, and that’s why we strive for zero safety incidents through our unique Behavior-Based Safety Management system. We’ve succeeded in achieving more than six years without a recordable safety incident. We credit our ongoing training and a culture of safety and accountability for keeping our employees safe and healthy.


Our success now and in the future is built on the core values that guide our business decisions: Safety, Sustainability, Integrity, Respect, Excellence and Value. The Harvey Gulf Code of Conduct is an integral part of upholding our company values and applies to every employee, contractor, consultant and agent who works on behalf of Harvey Gulf.


Harvey Gulf is the first and only U.S. vessel operator to own and operate offshore support vessels that operate exclusively on LNG.


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 Mexico.


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.


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.
