What Linjebygg does
Linjebygg AS is a Norwegian industrial services company founded in 1933 and headquartered in Molde, providing specialized inspection, maintenance, modification and access solutions to oil and gas operators on the Norwegian Continental Shelf and at Norwegian onshore processing facilities. The company offers eleven service lines including insulation, scaffolding, surface treatment, concrete rehabilitation, rigging, rope access, cutting and removal, flare tip replacement, wind turbine maintenance, advanced NDT inspection (VT, PT, MT, UT, PAUT, RT, PMI, Eddy Current), and ATEX/IECEx-certified habitat enclosures that allow hot work in explosive zones without production shutdown. It also operates differentiated proprietary equipment such as custom-designed diamond wire cutting systems capable of subsea cuts to 20m+ depth without ROV support.
The company earns revenue primarily through long-term frame agreements (rammeavtaler) with major energy operators including Equinor, ConocoPhillips, Shell, Eni and Aker BP, delivering services across 35 offshore facilities and land plants at Tjeldbergodden, Mongstad, Nyhamna, Øygarden and Verdal. Pricing is project-specific B2B quotations rather than published rates. Distribution is direct enterprise field sales through six Norwegian offices in Molde, Trondheim, Stavanger/Sandnes, Bergen/Sandsli, Skien and Østfold, supplemented by the global footprint of parent Altrad Group (50+ countries, roughly 60,000 employees, approximately NOK 40 billion in operating revenues). Linjebygg holds a 50.8% stake in MainTech AS, an asset integrity management subsidiary.
Following Altrad Group's acquisition of Beerenberg in autumn 2024, Linjebygg and Beerenberg established joint management on March 31, 2025, forming the largest ISO collaboration in Norway with combined revenue of NOK 4.4 billion and 2,500 employees, while the two entities remain legally separate. Linjebygg's standalone 2024 revenue was NOK 1,371 million, up from NOK 1,307 million in 2023, with 700-780 employees in Norway. The company is ISO 9001, 14001 and 45001 certified.
