American Offshore Services

What American Offshore Services does

American Offshore Services LLC (A-O-S) is a U.S.-based, Jones Act-compliant operator of crew transfer vessels (CTVs) serving the American offshore wind sector. Founded in 2020 and structured as a joint venture between European CTV operator Northern Offshore Services (N-O-S) and SEA.O.G Offshore (part of Crosby Tugs), the company is headquartered in North Kingstown, Rhode Island, with commercial, technical, and chartering functions co-located near its vessel builder, Blount Boats. A-O-S charters 30-meter G-Class aluminum hull vessels — currently M/V Gripper, M/V Generater, M/V Guarder, and M/V Gamekeeper — powered by four Volvo Penta D13-700 engines paired with Volvo Penta IPS900 steerable pod drives, and equipped with the patented N-O-G high-grip fender system developed by parent N-O-S.

The company's core service is the year-round (365-day) transport of technicians and cargo (up to 24 seats and 20 tons per vessel) to offshore wind farms and other offshore installations, with a forward deck crane (Palfinger PK12000MC), 114 m² forward and 40 m² aft deck areas, and onboard satellite communications. Fleet operations are managed through an ISO 45001 / ISO 9001 / ISO 14001-certified safety, quality, and environmental management system audited by ABS, and monitored via a Reygar BAREfleet vessel monitoring system. Revenue is generated primarily through vessel chartering contracts with offshore wind farm operators on a quote-based, project-driven basis, with chartering enquiries handled by a dedicated commercial team.

A-O-S is financially backed by Orion Infrastructure Capital (OIC), an infrastructure investor with approximately $4.5 billion in AUM, which provided construction financing for the G-Class series in February 2022. The company benefits from technical, operational, and proprietary technology transfer (notably the N-O-G fender IP) from N-O-S, which operates more than 60 vessels across Europe. Pricing is not publicly disclosed, the company is privately held with 11-50 employees, and the GTM motion is direct and relationship-driven, targeting a narrow set of U.S. offshore wind developers via corporate website, MyNewsDesk newsroom, Vimeo-hosted vessel media, and direct chartering outreach.

Direct peers

• Northern Offshore Services (N-O-S): Parent company and Europe's leading CTV operator with 60+ vessels. Operates an essentially identical G-Class platform with N-O-G fenders in European offshore wind, making it the closest direct peer and operating partner of A-O-S.
• Edda Wind: Norwegian-listed pure-play CTV operator serving European offshore wind with purpose-built vessels. Directly comparable business model, customer base, and asset class to A-O-S, though operating in European waters.
• Windcat Workboats: UK/Dutch CTV operator with a large fleet dedicated to offshore wind crew transfer. Same target market, same vessel category, and same customer base (wind developers) as A-O-S, though operating in European waters.
• ESVAGT: Danish offshore service vessel operator providing crew transfer and SOV services to European offshore wind. Comparable in customer base, vessel class, and offshore-wind focus, though ESVAGT operates larger SOVs in addition to CTVs.
• Tidal Transit: UK-based CTV operator serving European offshore wind. Comparable vessel type, customer base, and operational profile to A-O-S, though focused on European wind farms.

Broad incumbents

• Crowley Maritime: Large U.S. maritime operator with significant offshore wind CTV operations on the U.S. East Coast (e.g., WindServe Providence joint venture). Directly competes with A-O-S for U.S. wind charters and shares the Jones Act compliance framework.
• Bourbon (BOURBON Wind): Global offshore marine services provider with a dedicated offshore wind crew transfer business (Boka Atlantis vessels). Comparable in vessel type and customer base, though operating primarily in European and African wind markets.
• SEACOR Marine: U.S.-listed offshore support vessel operator with OSV fleet used for offshore energy support. Comparable in vessel operations and U.S. flag status, though SEACOR's fleet is more diversified across oil and gas and wind.
• Hornbeck Offshore Services: U.S.-based offshore vessel operator with Jones Act-compliant fleet serving Gulf of Mexico and other U.S. waters. Comparable in U.S. flag status and vessel operations, though traditionally focused on oil and gas OSV services.

Others

• Orion Infrastructure Capital (OIC): Financial partner of A-O-S with ~$4.5B AUM investing in renewable and infrastructure assets. Not a direct operating peer but a key capital partner and a useful comparable for understanding the infrastructure-financed vessel business model.
