What Sebastian AS does

Sebastian AS is an independent Norwegian maritime and offshore consultancy founded in 1994 and headquartered in Ulsteinvik, Møre og Romsdal. The company delivers specialized Dynamic Positioning (DP) assurance and consultancy services, including DP FMEA/FMECA analysis, DP trials, DP operations manuals, GAP analysis, and ASOG/SRtP documentation for vessels, rigs, and offshore installations. Its second core line, Verification & Validation (V&V), provides third-party quality and functionality assessments across marine assurance, MODU assurance, newbuilds, rig intake, retrofit, eCMID inspections, and incident investigations. A third pillar covers the energy industry, spanning oil and gas, renewables, aquaculture, and energy-transition advisory including maritime decarbonization.

The company's technology foundation is rooted in domain expertise rather than proprietary software. Its main digital asset is the Sebastian DPP (Dynamic Positioning Portal), a proprietary platform that gives fleet and vessel managers an overview of DP-related documentation, test windows, testing status, and findings management across vessels and rigs. Underlying capability rests on a team of FMEA Auditors, Company DP Authorities, Master Mariners, DP Specialists, and accredited vessel inspectors, supported by long-standing memberships in IMCA (since 2005), MTS (since 2014), and NORWEA / Norwegian Offshore Wind Cluster (since 2022).

Sebastian AS operates a B2B professional services model with quote-based pricing and multi-year contracts, generating revenue through project-based engineering and assurance engagements rather than licensed products. Services are delivered to shipyards, rig owners, ship owners, oil companies, and offshore contractors worldwide, with global reach enabled by wholly-owned subsidiaries in Brazil (Sebastian do Brasil AS, Rio de Janeiro) and China (Shanghai Sebastian Marine Technology Co. Ltd), plus the Norwegian HQ. GTM motion is enterprise field sales, with staff traveling to client locations for surveys, FMEA tests, and project meetings. Headcount is approximately 21, and the company has remained privately held without disclosed external funding.

Broad incumbents

• DNV: Global classification society and one of the largest marine assurance and verification providers. Performs DP FMEA verification, marine V&V, newbuild assurance, and offshore inspections — directly overlapping Sebastian's core services, but at much larger scale and as part of a broader class and advisory portfolio.
• Lloyd's Register: International classification society providing marine verification, DP FMEA review, and offshore assurance services. Comparable to Sebastian in DP-related work but offers a much wider portfolio including statutory certification, asset management, and digital tools.
• Bureau Veritas Marine & Offshore: Global testing, inspection and certification company with marine and offshore division. Performs DP system verification, FMEA, and class/flag services — overlapping Sebastian's V&V and assurance offerings with significantly broader geographic reach.
• American Bureau of Shipping (ABS): Classification society offering marine and offshore verification, DP FMEA services, and engineering review. Competes with Sebastian on independent third-party DP assurance and verification engagements for offshore vessels and units.
• Kongsberg Maritime: Norwegian supplier of Dynamic Positioning systems, integrated bridge systems, and automation for offshore vessels. Adjacent rather than direct — Kongsberg designs the DP systems that Sebastian's FMEA and assurance work audits — making it a closely related ecosystem participant.
• Wood Group: Global engineering and consultancy firm with significant offshore, marine, and energy transition practices. Overlaps with Sebastian's Verification & Validation, offshore assurance, and energy transition services at much larger scale.
• RINA: Italian classification society offering marine certification, DP FMEA verification, and offshore engineering services. Closely comparable to Sebastian in independent DP and marine assurance work but bundled with class and broader industrial services.

Direct peers

• Cathie Group: Independent offshore geoscience and engineering consultancy with strong offshore wind and marine site assessment capabilities. Most directly comparable to Sebastian's emerging Energy Transition and offshore wind advisory services line.
• Aqualis Offshore: Independent offshore engineering consultancy providing marine warranty, design review, and offshore energy advisory services. Closely comparable to Sebastian as a mid-sized independent consultancy serving offshore, energy, and renewables markets.

Others

• IMCA (International Marine Contractors Association): Industry trade association representing offshore, marine, and diving contractors. Sebastian has been an IMCA member since 2005; IMCA shapes the DP FMEA, ASOG, and CAM guidelines that define the regulatory framework Sebastian operates in — making it an ecosystem enabler rather than a competitor.
