Sea Shipping AS

What Sea Shipping AS does

Sea Shipping Group AS is a privately-held Norwegian maritime services company headquartered in Ulsteinvik, Norway, that operates a growing fleet of seven Ocean Energy Support Vessels (OESVs) for offshore energy customers. The fleet — comprising MS Patriot, MS Provider, MS Scotia, MS Atlantic, MS Trym, MS Saturn, and MS Server — is configured for subsea operations including ROV (Remotely Operated Vehicle) work, IMR (Inspection, Maintenance, and Repair), survey, boulder clearance, and multirole subsea support. Vessels are DPII-class (Dynamic Positioning II) fitted with Active Heave Compensated (AHC) cranes of 20-25 tonne capacity and accommodate 45-50 persons onboard. The company also converts legacy tonnage (e.g., AHTS to OESV) to extend asset life and improve energy efficiency, and holds ISM Code, ISO 9001, ISO 14001, and ISO 45001 certifications covering safety, quality, environmental, and occupational health management.

The company serves offshore energy operators — primarily oil and gas — across the North Sea, Baltic Sea, and Norwegian waters, with operating geographies also extending to the United Kingdom. Revenue is generated through time-charter contracts for vessels with crew (vessel chartering services) and through end-to-end commercial and technical management covering crewing, chartering, HSEQ, and operations. Pricing is quote-based per inquiry, determined by vessel specification, contract duration, and operational requirements; billing is structured around multi-year contracts.

Sea Shipping pursues a direct B2B enterprise go-to-market: vessels are chartered through a dedicated chartering function ([email protected]) with no public pricing or platforms, and the business is supported by a corporate LinkedIn presence, a fleet catalog on the company website, and a careers pipeline. The operating model is intentionally vertically integrated — commercial management, technical management, crewing, and HSEQ are bundled in-house — which the company positions as a means to deliver safe, efficient services at competitive economic and environmental terms while supporting field development, construction, production, and decommissioning of offshore energy structures.
