Northern Marine Group

What Northern Marine Group does

Northern Marine Group is a UK-headquartered, privately held ship management and marine services provider, operating as a wholly-owned subsidiary of the Swedish Stena shipping conglomerate. The company is organised around two service pillars: Ship Management (technical management of gas carriers, oil and chemical tankers, offshore assets and passenger ships, plus end-to-end crew management) and Marine Services, which spans marine engineering, training, crew travel management, quality assurance, offshore catering, and marine projects and ship agency. These service lines are delivered through wholly-owned operating subsidiaries including Tritec Marine, Clyde Marine Training, Clyde Travel Management, International Marine Assurance Services (IMAS), Francois Offshore Catering, and Austen Maritime Services, supported by a shore-based workforce of 101–250 staff across Aberdeen, Glasgow (Clydebank headquarters), Houston, Mumbai and Singapore.

Revenue is generated through long-term enterprise contracts with global ship owners, energy majors and financial institutions, predominantly on a managed-services basis for core ship management and on a professional-services basis for marine engineering, QA and training work; pricing is not publicly disclosed and is structured per-vessel and per-scope. The company has built a differentiated position in energy-transition vessel operations, with active experience across LNG, FSRU, LPG and methanol-fuelled tonnage — including three years of methanol operations and a recent expansion of dual-fuel tanker management (Largo Aurora, Largo Aries).

Technology infrastructure centres on the proprietary Aurora platform for predictive and condition-based maintenance, the Consort digital travel platform, and an in-progress fleet-wide rollout of Low Earth Orbit (LEO) satellite internet that enables real-time energy monitoring, regulatory compliance reporting (CII, EEXI, EU ETS, FuelEU), and condition-based interventions. The company operates a horizontal segmentation strategy targeting Ship Owners and Energy Companies as primary segments, with Offshore/Marine Contractors and external training clients as secondary segments, and pursues growth through direct enterprise field sales led by a dedicated Head of Business Development rather than channel partners.
