What GMC does
GMC Holding AS is a family-owned Norwegian industrial conglomerate founded in 1973 in Stavanger, operating through eight wholly-owned subsidiaries that collectively deliver maritime and offshore services across the Norwegian west coast. Its core service platform spans ship repair and maintenance (GMC Maritime), drydocking at one of Norway's largest dry docks at 279x42 meters (GMC Yard), electrical and automation systems (GMC Power and Automation), HVAC and cooling (GMC HVAC), lifting and mooring equipment sales, rental and certification (GMC Lifting Solutions), and base services plus marine operations including logistics, crew change and offshore project support (GMC Marine Partner). The group also operates a naval defense services line (Sjøforsvarstjenester) and a real estate development business (GMC Eiendom) anchored by the BREEAM-NOR Excellent certified Byfjordparken project in Stavanger.
The business is fundamentally infrastructure- and certification-intensive. GMC operates approximately 35,000 m² of outdoor and 5,000 m² of indoor workspace at Mekjarvik, two dry docks plus a 290-meter deepwater quay at Buøy, and additional bases at Hinna (50,000 m² storage), Aksdal/Gismarvik and the newly opened Hilleren base in Bergen. Its technology stack centers on heavy mechanical and welding capabilities (ISO 3834-2), domain-specialized lifting equipment (Sakkyndig Virksomhet S2 certifications), electrical and automation installation, and HVAC engineering, supplemented by agency partnerships with Cathelco, Novenco, Panasia/Samkun and Mooreast for antifouling, ventilation, green technology and mooring solutions respectively.
GMC generates revenue primarily through project-based B2B services contracts, multi-year framework agreements and equipment rental/sales, with no public pricing. Major customers include Equinor (700-800M NOK framework), the Norwegian Armed Forces (600M NOK framework for KNM Maud), Saipem (homeport services for the Saipem 7000), Aker BP (Hugin A platform), AKOFS (15-year vessel classification), Aurora Offshore, Rem Offshore, Fjord1 and Norled, plus recurring rental income from GMC Eiendom.
