A message from Shane Guidry, CEO & Chairman of the Board

It was in 1955 when my grandfather started this business, and today it’s my utmost honor to carry the Harvey Gulf International Marine legacy forward while also focusing on our continued evolution and making sure we live out our dedicated sustainability mission.


That mission: We want to be at the forefront of ESG efforts for our entire industry, to be the most environmentally friendly offshore vessel operator so that others will follow. At our core, we want to provide our customers excellent marine service and value while causing no harm to people, assets, or the environment.


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 that 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.


We’ve also installed a monitoring system to measure our emissions in real time. We will compare the emissions when our vessels run on battery power, natural gas, and diesel fuel. Establishing benchmarks is the most significant step we can take toward reducing our industry’s environmental impact.


Within the first 90 days of operating our vessels with the new monitoring system, we will have tested all modes under which our ships are fueled. At the end of 2021, we will have established benchmarks that will advise our long-term fuel decisions.


From our Board of Directors to our Executive Leadership Team to our shore- and crew-based employees, we’re committed to protecting our people, environment and communities.


We’re digging into our operations to understand the impact we’re having, and we’ll make adjustments based on our findings. Our company has hired two third-party consulting firms to perform a materiality assessment and help us understand where we stand on our ESG progress. In addition, we’re actively seeking a director of sustainability to drive our strategy moving forward.


As you can see, our legacy has evolved and so has our commitment to doing the right thing for our employees, our communities and our environment. To continue working, we all must push the limits and focus on doing the best we can to make the change we need—the change already set in motion.


We are excited about what the future brings, and we are confident that our efforts are just the beginning of the significant impacts we can make together moving forward.


Thank you.
Shane Guidry

Mapping our ESG Progress


As a pioneer in using Liquefied Natural Gas (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 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.

  • Harvey Gulf owns and operates the first and only US offshore support vessels that operate exclusively on LNG. LNG reduces carbon dioxide emissions by up to 26% as compared with conventional fuels. When using LNG, nitrogen oxide, sulfur oxide emissions and particulate matter, the three primary pollutants of the shipping industry, are reduced by up to 99%.
  • The vessels were also the first to receive the Enviro+ Green Passport Certification by the American Bureau of Shipping (ABS). Enviro+ certification requires a life cycle analysis beginning with the vessel’s design phase. Ships must be built using ABS-certified environmentally friendly materials. They must be equipped with advanced alarms for fuel tanks and containment to prevent environmental harm during the vessel’s use phase.
  • In another first for the industry, Harvey Gulf has installed real-time emissions monitoring systems to benchmark emissions from battery power, LNG, and diesel fuel. Establishing benchmarks is the most significant step a company can take toward reducing the industry’s environmental impact.
  • Within the first 90 days of operating its vessels with the new monitoring system, Harvey Gulf will have tested all modes under which ships are fueled. And, by the end of 2021, we will have established benchmarks that will advise the company’s long-term fuel decisions.


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.

  • Harvey Gulf has built a culture of safety among shore- and crew-based employees. A 52-week safety training matrix ensures all shore and crew employees are armed with the knowledge they need to keep themselves and their coworkers safe on the job. The company is one of the first US Offshore Marine companies to obtain an ISO 9001:2015 Quality Management System that has been audited and certified by the ABS.
  • The company’s safety program is centered around a real-time, behavior-based safety management system—Taking Aim at Behavioral Safety, or TABS. Harvey Gulf employees remain its most important resource. Through the TABS Program, employees are afforded the opportunity to participate in a simple but effective behavior-based safety program.
  • Unlike most behavior-based programs, which use anonymous and unannounced observations, Harvey Gulf employees notify and ask permission from the person or persons being observed beforehand. This contributes to the accountability of everyone on board. And TABS is working. Harvey Gulf has gone more than six years without a recordable safety incident.
  • Every new Harvey Gulf employee is assigned a mentor to advise them for the first six months of employment. Employees up to the executive leadership serve as mentors to employees across many departments.


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.

  • During the recent industry-wide downturn, Harvey Gulf expanded into Nigeria, Guyana, Suriname, Mexico and Trinidad. This expansion allowed the company to keep its customer commitments and the majority of its employees working. Harvey Gulf increased is operational results by more than 30% when many of its competitors suffered significant declines.
  • When the COVID-19 pandemic struck in 2020, Harvey Gulf launched a multi-purpose vessel to isolate its crew and that of several customers. Under CDC guidelines, the company implemented protocols to eliminate contact between shore-based employees and crew to prevent virus spread. This quick action prevented pandemic-related shutdown for both Harvey Gulf and its customers.
  • The Harvey Gulf Board of Directors, specifically the Audit Committee, manages yearly independent audits with Deloitte. The Governance Committee oversees adherence to the company’s Code of Conduct, which applies to every director, officer, and employee, including contract employees while they are working for Harvey Gulf.
  • Third-party contractors, consultants and agents who work on behalf of Harvey Gulf must act consistently with the Code as a condition of doing business with the company


Harvey Gulf is the first and only U.S. Vessel operator to own and operate offshore support vessels that operate exclusively on liquefied natural gas.

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 OSV’s to achieve this certification, making them the most environmental friendly OSV’s in Gulf of Mexico. 

Harvey Gulf continues its commitment to environmental protection by becoming the first to build U.S.A. 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 America, 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 State Coast Guard 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 to remain an industry leader in the nation’s growth towards LNG and cleaner burning fuels. The Company’s dual fuel LNG vessels exceed the highest emission standards in the industry today, and LNG fueling facility further solidifies Harvey’s commitment to develop and utilize the safest, most environmentally-friendly vessels and fuel technology available today.
