Aries Marine Corporation

What Aries Marine Corporation does

Aries Marine Corporation is a privately held Louisiana corporation founded in 1981 by Dwight S. "Bo" Ramsay that owns and operates a fleet of 11 offshore marine vessels, comprising six self-elevating liftboats (Class 130' to Class 200') and five supply vessels (Class 220' to 230' DP OSV/PSV plus a heavy deck carrier). The liftboats provide mobile work platforms with crane capacities from 10 to 120 tons and deck load capacities up to 800,000 lbs in water depths up to 160', while the supply vessels are equipped with DPS Class 1 and Class 2 Z-Drive thrusters for station keeping during offshore offloading. Specialized assets such as the MV RAM COMMANDER add ice-class heavy-lift capability with ballast water management, extending the company's reach to West Coast, Alaska, and Hawaii projects in addition to the Gulf of Mexico and East Coast Atlantic core.

The company serves offshore oil & gas producers (both majors and independents), offshore wind developers, U.S. government/defense customers including Military Sealift Command and the U.S. Navy, and geotechnical/industrial clients. Liftboats are used for platform maintenance, workover operations, pipeline repairs, well hook-ups, rig tending, and salvage operations, while supply vessels transport liquid and dry bulk cargo, drilling mud, water, and fuel. Aries Marine maintains industry association memberships with NOIA, OMSA, the Business Network for Offshore Wind, ISN World, and DISA, and is operated under family leadership with Court B. Ramsay serving as President, CEO, and Chairman of the Board, Richard Andrus as COO, and Avis Bourg as Director of Sales.

Revenue is generated primarily through direct, quote-based charter contracts with enterprise customers, structured around two operating divisions — Liftboat and Supply Boat — each with dedicated sales contacts. Recent operating context includes 2026 reports of Trump administration stop-work orders on U.S. offshore wind projects idling liftboats and triggering layoffs, and a February 2026 Fifth Circuit ruling denying Aries Marine contractual indemnity and additional insurance recovery from United Fire and Safety under a nonmaritime contract determination. The company is not publicly traded and discloses no revenue or headcount beyond a 101-250 employee range.

Expansion highlights5 records

Direct peers

• Hornbeck Offshore Services: Privately-held U.S. OSV operator historically focused on new-build, U.S.-flagged liftboats and supply vessels serving deepwater oil & gas in the Gulf of Mexico — the closest direct comp to Aries' liftboat + PSV model.
• SEACOR Marine Holdings: NYSE-listed OSV operator with a global fleet of platform supply vessels, crew boats, and specialty vessels serving offshore oil, gas, and wind — directly comparable customer mix and vessel classes to Aries.
• Tidewater Inc. Largest pure-play OSV company globally, operating a fleet of platform supply vessels and other offshore support craft. Direct competitor in the same charter-driven offshore services market Aries serves.
• Edison Chouest Offshore: Privately-held, diversified U.S. offshore vessel operator with a large fleet of PSVs, crew boats, and specialty vessels serving Gulf of Mexico, international, and increasingly offshore wind markets — directly comparable to Aries' charter model and customer base.
• Harvey Gulf International Marine: U.S.-based OSV operator specializing in dual-fuel (LNG) and conventional platform supply vessels serving the Gulf of Mexico. Direct competitor in the U.S.-flagged PSV charter market for offshore oil & gas.

Broad incumbents

• Vantage Drilling International: Offshore drilling contractor (jack-ups and ultra-deepwater drillships) that historically also operated OSVs. Overlaps with Aries in the Gulf of Mexico oil & gas customer base, though focused on drilling rather than vessel support.

Regional players

• Bourbon Corporation: French-headquartered OSV operator with a large fleet of PSVs and crew boats primarily serving West African and international deepwater markets. Comparable vessel classes and offshore oil & gas charter model, but with limited U.S. Gulf of Mexico presence.

Emerging players

• Bristow Group: Leading global helicopter operator serving offshore oil & gas and increasingly offshore wind (via the 2024-Air的业务). Adjacent to Aries in offshore wind logistics support, though it transports people rather than cargo and works offshore platforms.
