What North Star does

North Star is a UK-based offshore service vessel operator founded in 1886 and headquartered in Aberdeen. The company operates the largest UK-owned fleet serving the offshore industry — 48 dedicated offshore vessels crewed by approximately 1,500 personnel — and provides four core service lines: Offshore Wind Support (crewing and tailored support for wind farm operations), Emergency Response and Rescue (ERRV, 24/7 safety services), Platform Supply and Multi-Role Vessels (the world's largest MRV fleet combining ERRV and PSV capabilities), and Rescue Boat Services (Daughter Craft). North Star's technology stack includes walk-to-work gangway systems for safe personnel transfer, Dynamic Positioning (DP) systems, hybrid vessel drive technology with planned methanol conversion capability, and purpose-built vessel designs — integrated end-to-end from vessel design and crewing through maintenance and compliance.

The company serves three primary customer segments: offshore wind developers and operators (primary), oil and gas platform operators, and offshore marine contractors. Revenue is generated through long-term recurring charter contracts bundled with integrated crewing, maintenance, and compliance services, sold via direct enterprise sales to major energy companies. Recent strategic activity includes a mega ship deal with RWE (one of the world's largest offshore wind developers), a VARD contract for two hybrid service vessels for 2027-2028 delivery, a four-vessel fleet expansion, major North Sea ERRV contract wins, C-suite expansion for international growth, and approximately $287.8M raised in a 2024 funding round from infrastructure investors including IFM Investors, ABN AMRO, RBC Capital Markets, and the Scottish National Investment Bank. Capital intensity is high, with £1.5bn invested in offshore assets since 2001.

Others

• BOURBON:

Direct peers

• ESVAGT: Danish-based offshore service vessel operator and recognized global leader in ERRV/SOV services for the offshore wind and oil & gas sectors. Closely comparable to North Star on geography (North Sea), fleet composition (ERRVs and SOVs), and customer base (offshore wind developers and O&G operators).
• Vroon Offshore: Dutch offshore support vessel operator with significant SOV/subsea/PSV exposure serving the North Sea offshore wind market. Directly comparable on vessel types, North Sea geography, and blue-chip offshore wind customer base.
• Edda Wind: Norwegian pure-play offshore wind SOV operator with a fleet purpose-built for the European offshore wind market. Highly comparable to North Star's SOV/MRV offering and end-market focus on offshore wind developers.
• Siem Offshore: Norwegian OSV company with PSV, AHTS, and SOV vessels serving offshore oil & gas and offshore wind customers, including North Sea operators. Comparable on vessel mix and customer base; operates at larger global scale.

Broad incumbents

• DOF Group: Norwegian-headquartered global OSV owner-operator with a large AHTS/PSV/subsea fleet. Comparable on vessel categories (PSV/AHTS) and global OSV operations, but broader and more diversified than North Star's North Sea-centric ERRV/SOV focus.
• Solstad Offshore: Norwegian global OSV operator with large AHTS/PSV/subsea fleet. Comparable on vessel categories and North Sea presence, though diversified globally across subsea construction and traditional O&G support.
• Tidewater Inc. Largest global OSV owner-operator with deep PSV/AHTS fleet across regions. Comparable business model (offshore vessel chartering) but broader, globally diversified, and focused more on oil & gas than ERRV/wind.
• Edison Chouest Offshore: Privately held, US-headquartered global OSV operator with a large, diversified fleet of supply, crew transfer, and specialty vessels. Comparable on the integrated vessel-support model, though with a much wider geographic and end-market footprint than North Star.

Regional players

• Havila Shipping: Norwegian offshore PSV/AHTS operator serving the Norwegian and North Sea markets. Comparable on vessel types and North Sea customer base but smaller-scale and primarily O&G-tilted rather than ERRV/wind-led.
