What Leirvik does

Leirvik AS is a Norwegian engineering, procurement, and construction (EPC) contractor founded in 1946 and headquartered in Stord, Norway, specialising in aluminium construction for the offshore energy industry. The company designs, fabricates, and delivers aluminium living quarters, helidecks, technical modules, and large structural modules for oil and gas platforms, offshore wind installations, and infrastructure projects. Its core technology stack rests on five decades of aluminium-specific welding, fabrication, and assembly know-how executed at the company's Aslaksvik yard, with modern production equipment including plasma cutters, water cutters, welding robots, and automated module lines. Leirvik also offers 'Connected LQ,' a smart monitoring add-on for energy and water consumption in offshore accommodation, and is developing 'OptiRAS,' a proprietary land-based recirculating aquaculture system co-developed with SeaRAS that claims one-third the energy use of traditional RAS facilities.

The business is organised into four verticals: Living Quarters & Large Modules, Modifications & Modules (lifetime extensions and maintenance), Aquaculture, and Infrastructure (aluminium bridges and civil structures). Revenue is generated through project-based fixed-price EPC contracts won via formal tendering with major oil and gas operators, supplemented by maintenance and modification services on aging platforms. The customer base is concentrated among European and international offshore majors — Equinor, ExxonMobil, Shell, Vår Energi, and Kværner — alongside government clients such as Møre og Romsdal Fylkeskommune and Statens vegvesen for the newer infrastructure work. Leirvik holds a comprehensive set of oil & gas and welding certifications (ISO 9001, ISO 14001, ISO 3834-2, OHSAS 18001, Achilles JQS, Achilles FPAL) and operates internationally, including a Singapore joint venture (Apply Leirvik International) for Asian and Australian markets. The company has been under employee ownership since a September 2021 management buyout and currently employs roughly 330 people.

Broad incumbents

• Saipem: Global offshore EPC contractor with extensive offshore platform and wind experience. Competes for large integrated offshore scopes and could pre-empt Leirvik on offshore wind accommodation mega-tenders internationally.
• Aker Solutions: Largest Norwegian offshore EPC incumbent providing integrated topsides, subsea and maintenance services to oil & gas and offshore wind operators. Competes with Leirvik on integrated platform scopes and offers living-quarter capabilities as part of a much broader portfolio.
• Aibel: Major Norwegian offshore EPC contractor with deep NCS relationships (Equinor, etc.) providing platform modifications, maintenance and new-build modules. Directly competes for the same modification and life-extension contracts that form a key part of Leirvik's revenue.

Others

• Hydro (Norsk Hydro): Global aluminium supplier partnered with Leirvik on Grøttabrua to provide low-carbon, high-recycled-content aluminium. Not a direct competitor but a critical supplier and ecosystem enabler for Leirvik's aluminium value proposition and sustainability positioning.
• Nexans: Global offshore cable and infrastructure supplier serving the offshore wind market. Not a direct competitor but a relevant adjacent player in the offshore wind supply chain that Leirvik participates in through its offshore wind business area.

Emerging players

• SeaRAS: Bergen-based technology partner co-developing OptiRAS, a next-generation land-based recirculating aquaculture system with substantially lower energy consumption. Direct peer and partner in the aquaculture business area Leirvik is building.
• Dr.Techn. Olav Olsen: Norwegian structural engineering firm specializing in aluminium and steel bridges and offshore structures; partner with Leirvik on the Grøttabrua R&D bridge. Comparable in that it brings engineering depth to aluminium infrastructure, a market Leirvik is also entering.

Direct peers

• Apply Emtunga: Former sister company within Apply Group, Apply Emtunga fabricates offshore living quarters and modules. Was the productivity benchmark (15 hours/sqm) for Leirvik's 42-15 efficiency program and is the most directly comparable EPC peer in offshore aluminium modules.
• Aluminium Offshore: Singapore-based aluminium constructor specializing in helidecks and offshore modules, and Leirvik's 50/50 JV partner in Apply Leirvik International (ALIP) for Asia-Pacific markets. Direct peer in aluminium offshore fabrication serving the same oil & gas and offshore wind customer base.

Regional players

• Multiconsult: Leading Norwegian engineering consultancy active in infrastructure (road, bridge, rail) and energy markets, including framework agreements with Møre og Romsdal Fylkeskommune alongside Leirvik. Competes for engineering scope on Norwegian public-sector bridge projects where Leirvik supplies fabrication.
