What Prosafe does

Prosafe SE is a Norwegian publicly listed company (OSE: PRS) and one of the world's largest owners and operators of semi-submersible offshore accommodation vessels. The company operates a fleet of five Accommodation, Safety and Support Vessels (ASVs) — Safe Boreas, Safe Zephyrus, Safe Notos, Safe Eurus, and Safe Caledonia — plus one Tender Support Vessel (TSV). These vessels provide hotel-quality accommodation for up to 500 people each, alongside welfare and catering facilities, storage, workshops, offices, medical services, deck cranes, and lifesaving/firefighting equipment, and they are deployed across offshore oil and gas regions including Brazil, the UK North Sea, and Australia.

The company's underlying technology centers on its semi-submersible hull design and station-keeping systems. Four vessels are dynamically positioned (DP2 and DP3) and one uses passive position mooring (POSMOOR), enabling stable operations in harsh offshore environments such as the Norwegian and UK Continental Shelves. Safe Boreas and Safe Zephyrus hold Acknowledgments of Compliance from the Norwegian Petroleum Safety Authority (PSA), and Prosafe maintains ISO 9001, 14001, 45001, and 50001 certifications across its management systems. This regulatory compliance, combined with three decades of operational track record and over 184 contracts executed, is the technical and reputational backbone of the company's value proposition to oil and gas operators.

Prosafe generates revenue primarily through day-rate vessel charters under multi-year contracts with national oil companies, super majors, majors, and large independent operators. The company sells exclusively through direct enterprise field sales and formal tender processes, with Bid Committee oversight for contracts above USD 10 million and senior executive involvement in major bids. Backlog stands at USD 403 million including options, providing revenue visibility into 2027. Recent operating data shows a clear inflection: fleet utilization rose from 57% in 2025 to 79% in May 2026 (with 100% utilization reported in Q4 2025), Q1 2026 EBITDA tripled to USD 14.8 million from USD 4.6 million year-over-year, and full-year 2026 EBITDA is guided at USD 45–55 million. Customer relationships are anchored by long-running charters with Petrobras in Brazil and Ithaca Energy in the UK.

Direct peers

• Vroon: Dutch offshore service vessel operator with a fleet that includes accommodation/support vessels serving oil & gas and offshore wind operators across NW Europe and globally. Directly comparable to Prosafe in vessel type (ASVs/PSVs), customer base (oil & gas majors and NOCs), and day-rate chartering model.
• ESVAGT: Danish operator of offshore service vessels including accommodation walk-to-work and SOV platforms for the oil & gas and offshore wind sectors in the North Sea. Comparable in providing high-spec offshore accommodation to upstream operators with similar regulatory requirements (UKCS, Danish, Norwegian sector).
• North Star Renewables: UK-based operator of offshore service vessels with growing exposure to accommodation, SOVs, and PSVs serving the North Sea oil & gas and offshore wind markets. Similar business model of long-term charter contracts to majors and NOCs in harsh-environment geographies overlapping Prosafe.

Broad incumbents

• BW Offshore: Singapore/Oslo-listed owner/operator of FPSOs serving global deepwater oil & gas operators including Petrobras in Brazil. Comparable as a Norwegian-listed offshore services peer with deep overlap in the Brazil pre-salt customer base, though the FPSO product differs from Prosafe's accommodation vessels.
• Bourbon Corporation: French global owner of a large fleet of offshore support vessels (PSVs, AHTS, crew boats) serving the international oil & gas industry. Comparable as a broad offshore marine services incumbent, though Bourbon's portfolio is significantly broader than Prosafe's accommodation focus.
• Seacor Marine Holdings: US-based provider of offshore marine services including PSVs, AHTSs, and accommodation/utility vessels for the oil & gas industry. Comparable in vessel operations and customer overlap, though Seacor's geographic and product focus skews toward the Gulf of Mexico and Americas.
• Tidewater Inc. US-listed global owner of one of the largest OSV fleets (200+ vessels) serving offshore oil & gas operators worldwide. Comparable as a broad incumbent in the same offshore marine services space, with overlap in customer base (major IOCs and NOCs) and day-rate chartering model.

Emerging players

• Vallianz Holdings: Singapore-based offshore support vessel operator focused on the Middle East and Asia-Pacific markets, with a fleet serving national oil companies. Comparable as a smaller OSV operator competing for similar tender opportunities, though smaller scale and focused on different geographies than Prosafe.

Regional players

• DOF Group: Norwegian OSV operator with AHTS, PSV, and subsea construction vessels serving the same North Sea, Brazil, and Australasia oil & gas customers as Prosafe. Comparable in customer overlap and Norwegian-listing/regulatory context, but product mix is broader than Prosafe's accommodation focus.
• Solstad Offshore: Norwegian owner/operator of offshore support vessels (AHTS, PSVs, subsea construction) serving global oil & gas operators. Directly comparable as a Norwegian-listed OSV peer competing for similar tenders and capital, though Prosafe's pure-play ASV focus is a narrower specialisation.
