Direct peers

• Siem Offshore: Norwegian-based offshore support vessel owner-operator serving oil & gas and renewable energy clients with PSVs, AHTS, and offshore service vessels. Compares closely on NCS presence, fleet configuration (DP vessels, ROV, subsea), and customer overlap with Atlantic Offshore's North Sea oil & gas clients.
• Solstad Offshore: Large Norwegian-based offshore support vessel owner with AHTS, PSV, and subsea construction vessels serving the Norwegian Continental Shelf and global OSV markets. Directly comparable as a North Sea-focused OSV operator with overlapping fleet capabilities (emergency response, supply, ROV, subsea services).
• Vroon Offshore: Dutch-based offshore services operator with PSV, AHTS, and subsea vessels active in the North Sea. Comparable as a regional OSV operator serving oil & gas clients with emergency response, supply, and subsea inspection capabilities overlapping Atlantic Offshore's service mix.
• DOF Group: Norwegian-headquartered OSV and subsea services operator with PSV, AHTS, and subsea construction vessels active in the North Sea and globally. Comparable business model offering vessel charter, emergency response, and subsea services to oil & gas operators with significant NCS footprint.
• Østensjø Rederi: Norwegian family-owned offshore service vessel operator with PSVs, AHTS, and offshore wind vessels active in the North Sea. Comparable as a regional Norwegian-headquartered private operator with overlapping fleet and customer profile in the offshore support segment.

Broad incumbents

• Tidewater: Largest global OSV operator with broad geographic and vessel-type coverage including PSVs in the North Sea. While Atlantic Offshore is regionally focused on the NCS, Tidewater's global scale and North Sea PSV fleet make it a relevant incumbent benchmark for vessel type, customer category, and tender competition.
• Maersk Supply Service: Denmark-headquartered global OSV operator with anchor-handling, tow, and supply vessels serving the North Sea oil & gas market. Operates at greater scale than Atlantic Offshore but directly comparable on geographic market, vessel type (PSV/AHTS), and oil & gas client base on the NCS.
• Bourbon Offshore: French-headquartered OSV operator with global fleet of PSVs and AHTS vessels, including North Sea activity. Operates at significantly larger scale than Atlantic Offshore and is a relevant incumbent benchmark for vessel charter and oil & gas support services on the NCS.

Emerging players

• ESVAGT: Danish-headquartered operator of offshore service vessels (SOVs, ERRVs) for the European offshore wind and oil & gas markets. Comparable on Emergency Response and Rescue Vessel (ERRV) capability and North Sea geographic focus, but ESVAGT has a stronger pivot into offshore wind, illustrating an adjacent strategic path for Atlantic Offshore.

Regional players

• Edda Accommodation: Norwegian-based offshore service vessel operator providing accommodation, ERRV, and support services primarily in the North Sea. Comparable regional positioning and emergency-response/standby service capability overlap, though positioned more toward accommodation and renewable offshore wind service vessels.
