Maritime Global Services

What Maritime Global Services does

Maritime Global Services (MGS) is a Glasgow-headquartered marine quality assurance provider that delivers 24/7 inspection, validation, and consulting services exclusively to a single energy major client, identified by its proprietary MESQAC framework as ExxonMobil. Its core service portfolio spans marine quality assurance, vessel inspections (oil/chemical tankers, gas carriers, OSVs, FPSO/FSUs, semi-submersibles, drilling vessels), marine terminal inspections, marine security, marine consulting, offshore marine assurance, and dynamic positioning assurance. The underlying methodology combines extensive multi-source data analysis with full validation of vessel operators' TMSA (Tanker Management and Self-Assessment) and OVMSA (Offshore Vessel Management and Operations Self-Assessment) submissions, supported by two publicly distributed document standards: MESQAC (gatekeeping criteria for ExxonMobil affiliate service eligibility across coastal, inland barge, and unrestricted vessel categories) and CLIP (Collective Learning for Incident Prevention bulletins addressing emerging industry incident trends).

The company operates as a sales-led, direct enterprise model under bespoke contractual arrangements with one counterparty, with no public pricing disclosed and no alternative enterprise customers served directly. All new marine quality assurance enquiries are redirected to its sister company International Marine Assurance Services (IMAS), established in 2024 to serve the broader non-exclusive market. MGS is a subsidiary of Northern Marine Group Ltd (registered company SC474118), itself part of the Stena Group, with 11-50 employees, GDPR-compliant data handling, and global operational reach despite its UK domicile. The company holds no disclosed patents, AI/ML capabilities, external funding, or public valuation signals, and its revenue mechanics are entirely subscription/recurring in nature given the exclusive long-term service contract structure.

Broad incumbents

• DNV Maritime: DNV is a major classification society and maritime advisory firm offering vessel inspection, fleet QA, and incident investigation services. Comparable in inspection and QA scope though it spans classification, statutory certification, and broader advisory beyond energy-major QA.
• Bureau Veritas Marine & Offshore: One of the major classification societies offering vessel inspection, certification, and marine QA services globally. Comparable through its vessel vetting, terminal audits, and marine consultancy offerings, though it operates across a much wider portfolio including classification, certification, and statutory services.
• RINA Services: RINA is an Italian classification society offering marine certification, vessel inspection, and offshore QA services. Comparable to MGS in vessel vetting and marine assurance scope, with overlap in tanker, gas carrier, and offshore vessel categories.
• American Bureau of Shipping (ABS): ABS is a classification society providing vessel inspection, marine QA, and offshore assurance services with strong presence in energy and offshore markets. Comparable to MGS in serving energy majors with vessel vetting and offshore marine assurance.
• Lloyd's Register: Lloyd's Register is a global classification society providing vessel inspection, marine assurance, and consulting services to ship operators and energy clients. Comparable to MGS through marine QA and offshore assurance offerings, though it operates at much larger scale across full classification services.

Others

• Intertanko: International Association of Independent Tanker Owners is an industry association whose members are subject to vessel vetting and TMSA processes that MGS assesses. Relevant ecosystem participant as the customer-side counterpart to MGS's QA services.
• OCIMF: Oil Companies International Marine Forum is the industry body that owns the SIRE vessel inspection programme and TMSA framework that MGS validates against. It is not a competitor but is highly relevant as the standards-setting counterpart to MGS's QA validation services.

Direct peers

• RightShip: RightShip is a leading vessel vetting and maritime ESG/risk ratings provider serving charterers, operators, and energy majors. Directly comparable as it assesses vessel operators and provides ship inspection/quality data services to the same enterprise maritime customer base that MGS serves.
• SQE Marine: SQE Marine is a specialist vessel inspection and marine QA company serving tanker and gas carrier operators, including SIRE/CDI inspections and TMSA-related services. Closely comparable to MGS's TMSA/OVMSA validation and vessel inspection work.
• International Marine Assurance Services (IMAS): IMAS is MGS's sister company established in 2024 to deliver the same top-tier marine quality assurance services to the broader market. It offers the identical service catalogue (vessel inspections, terminal inspections, marine security, consulting, offshore marine assurance, dynamic positioning assurance) but serves non-ExxonMobil clients. Most directly comparable peer given shared DNA, methodology, and operational model.
