What Harvey Gulf does

Harvey Gulf International Marine, LLC is a privately held, family-owned marine transportation company founded in 1955 in Louisiana and now headquartered in New Orleans. The company operates a 26-vessel fleet (21 US-flagged and 5 Mexican-flagged) of Offshore Supply Vessels (OSVs), Fast Supply Vessels (FSVs), and Multi-Purpose Support Vessels (MPSVs), all DP-2 certified and serving deepwater and ultra-deepwater oil and gas operations in the U.S. Gulf of America and select international markets. Harvey Gulf is the first and only company in North America to operate offshore support vessels powered completely by LNG, with a tri-fuel propulsion architecture combining LNG, battery, and diesel power; the entire LNG fleet completed battery-hybrid integration by end of 2022.

The company's core technology platform centers on LNG-powered marine propulsion, integrated with battery hybridization and ABS-certified environmental and quality systems (ISO 9001:2015, ENVIRO+ Green Passport, ACCU). At Port Fourchon, Louisiana, Harvey Gulf owns and operates North America's first LNG marine fueling facility (270,000-gallon storage, 550 GPM transfer rate, 1,000+ successful LNG transfers and 20+ million gallons bunkered since 2015), alongside 1,600 linear feet of waterfront dockage supporting shore-side maintenance, fuel services, and crew training. The wholly-owned Quality Tank Cleaning LLC subsidiary extends the operating base into industrial tank cleaning. Together, these capabilities create an integrated Gulf of America hub for offshore support services.

Harvey Gulf generates revenue primarily through contract-based vessel charter services to major and supermajor oil and gas companies and drilling contractors, characterized as subscription/recurring in nature. Transaction-fee revenue streams include Port Fourchon dock and fuel services, LNG bunkering for third-party vessels, and Quality Tank Cleaning services. The go-to-market is direct enterprise field sales led by a President of Sales and Marketing, with operations supported by dedicated supply chain and logistics leadership. Customer concentration is high by the nature of the deepwater E&P buyer set, but a six-year-plus recordable-incident-free safety record, first-in-class regulatory certifications, and recognized operational performance (e.g., M/V Harvey America's 2025 customer safety recognition) reinforce commercial stickiness within the enterprise oilfield services buyer base.

Emerging players

• Vantage Drilling International: Vantage Drilling is an offshore drilling contractor with overlapping Gulf of America operations and customer base (major and supermajor oil companies). While primarily a drilling company, it competes for the same offshore E&P wallet and benefits from similar basin dynamics.
• DOF Subsea: DOF Subsea is an international OSV and subsea construction operator with MPSVs supporting IMR and ROV operations. It overlaps with Harvey Gulf's MPSV/subsea support offering and serves similar IOC customers, though concentrated in the North Sea and Brazil.

• Vallianz Holdings: Vallianz is an OSV-focused operator serving Middle East and Asia-Pacific offshore markets. It is comparable in business model and vessel offering to Harvey Gulf but serves a different geography.

Regional players

• Solstad Offshore: Solstad Offshore is a Norwegian-based global OSV operator with a large AHTS and PSV fleet. It is comparable in vessel type and customer segment but operates primarily in the North Sea and does not directly compete in the Gulf of America.

Others
