What Glomar Offshore does

Glomar Offshore B.V. is a family-owned, family-equity offshore support vessel (OSV) operator founded in 2006 and headquartered in Den Helder, Netherlands, with additional offices in Aberdeen, UK and Gdynia, Poland. The company operates a diversified fleet of 21 purpose-built vessels across ERRV, Safety Standby, Guard & Chase, Multi-purpose, Survey, and Chartered categories, serving offshore oil & gas operators (notably as a leading Safety Standby Vessel provider to the Dutch sector and ERRV provider in the UK sector), offshore wind developers (geophysical, geotechnical, and environmental surveys plus walk-to-work accommodation), subsea and decommissioning contractors, and marine research institutions. Core technical capabilities include dynamic positioning systems for automated station-keeping, DISCOM emission reduction systems delivering NOx below IMO Tier III limits, and a fleet-wide HVO40 biofuel transition supported by a partnership with FincoEnergies/GoodFuels, with the company certified at CO2 Performance Ladder Level 3 since August 2024 and targeting an 82% CO2 reduction by 2031.

The group is organized under parent Glomar Holding B.V. and comprises wholly-owned operating subsidiaries including Glomar Offshore Windsupport BV, Glomar Shipmanagement BV, Glomar Subsea BV, Northsea Offshore Services BV, Mairan Shipping BV, and the Seaspan brand entities. Vessel design and construction are anchored at the company's own shipyard, Globaltic Marine in Gdynia, Poland, which provides a vertically integrated capability uncommon for European OSV operators. Revenue is generated through bespoke, quote-based time charters sold via direct enterprise sales and industry tender processes, with multi-year contracts typical for major operator clients; pricing is not publicly disclosed and the company reports no public revenue figure.

Glomar markets a comprehensive compliance and safety posture (ISO 9001/14001/45001/50001, ISM, ISPS, MLC, Safety Culture Ladder Level 3, IMCA and ERRVA memberships) and reports 5+ years without accidents. Distribution is direct B2B via website, email, and 24/7 phone, supplemented by a LinkedIn presence, newsletter/availability list, and participation in European sustainability initiatives; stated geographic focus is Europe (North Sea and Mediterranean) with intent toward North/West Africa.
