AF Offshore Decom

What AF Offshore Decom does

AF Offshore Decom is a specialized business unit within AF Gruppen ASA, a publicly listed Norwegian construction and engineering group (Oslo Stock Exchange: AFG), focused on the safe removal, transport, dismantling, and recycling of end-of-life offshore oil and gas installations. Its core capability centers on AF Environmental Base Vats, one of Europe's most modern reception facilities for decommissioned offshore installations, located on Norway's west coast. The site features a 200-metre custom skid track levelled with ±5mm precision to handle structures up to ~12,000 metric tonnes in a single lift, with patented lifting point installation methods developed for extreme-weather North Sea removals (notably the H7 platform). Recent flagship projects include the Eider Alpha topside disposal for TAQA UK, the Andrew Platform decommissioning for BP in partnership with Heerema Marine Contractors (HMC), and the Huldra A Disposal, which achieved over 98% steel recycling. AF reports target materials recovery of 97%+ and partners with a hydropower-powered electric arc furnace recycler whose process emits 85% less CO₂ than ore-based steel production (a 1.9-tonne CO₂ reduction per tonne of recycled metal).

The unit operates a project-based professional services model, generating revenue through multi-year, quote-driven contracts awarded via competitive tendering by offshore operators and marine contractors, with disclosed contract values described as ranging from multi-million to multi-hundred-million NOK. Customers include TAQA UK, BP, Heerema Marine Contractors, and Allseas. In April 2026, AF Gruppen acquired Claxton Engineering Services for ~NOK 800 million, adding proprietary surface and subsea riser equipment, approximately 400 employees, and international hubs in the UK, USA, Singapore, Australia, and UAE. The Claxton acquisition positions AF Offshore Decom for geographic expansion beyond the North Sea and entry into offshore wind installation and life-extension services, broadening its addressable market from oil & gas decommissioning into adjacent offshore energy infrastructure.

Revenue is recognized on a per-project basis as offshore removal, transport, dismantling, and recycling services are delivered; ancillary environmental services (Environmental and Reuse Assessments, Nature Restoration, Environmental Centres for contaminated bulk material) provide an integrated recovery and remediation layer supporting ESG outcomes. Within the AF Gruppen group, the Offshore business area grew 24% YoY in Q1 2026 with revenue reported at the consolidated group level (NOK 7,978 million in Q1 2026), and an order backlog of NOK 44,486 million at quarter-end.

Revenue model

1. Offshore Decommissioning Services: AF Offshore Decom generates revenue through project-based contracts for the removal, transport, dismantling, and recycling of offshore oil and gas installations. Revenue is recognized on a per-project basis as services are delivered. Contract values range from multi-million NOK for individual projects to multi-hundred-million NOK for large campaigns. AF Gruppen also reports Offshore as a business area with revenues growing 24% year-over-year in Q1 2026, though AF Offshore Decom specifically delivered weak results in that quarter.
2. Environmental Base Operations: AF Environmental Base Vats serves as the onshore reception and processing facility for decommissioned offshore installations. Revenue is generated as part of the overall decommissioning service, processing materials for recycling including steel, marine growth (composted into topsoil), and hazardous waste treatment.
