What Kongsberg Ferrotech does
Kongsberg Ferrotech is a Norwegian subsea robotics company founded in 2014 and headquartered in Kongsberg, Norway. It develops and operates remotely operated robotic systems — Nautilus (horizontal tubular/flowline applications), Oktapous (vertical tubular/riser and conductor applications), Hullius (vessel hull and floating structure repair), and Exoskeleton — designed to perform inspection, repair, and maintenance (IRM) of underwater installations at depths up to 1,500 meters without ROVs, divers, or vessel-supported equipment. Core technology revolves around automated underwater habitats that create dry working environments on the seabed, enabling in-situ composite repairs, corrosion protection, and additive manufacturing (subsea 3D printing) developed through the SAMLE joint industry project with Equinor, Gassco, SINTEF, and Shell. DNV qualification for non-metallic subsea repair (a first in the industry), UK-granted patents for 3D printing and digital repair methods, and ADIPEC 2020 and OTC Asia 2022 industry awards validate the technology platform.
Kongsberg Ferrotech generates revenue through professional services contracts for robotic IRM work delivered directly to enterprise customers via field sales. Pricing is custom and not publicly disclosed, with multi-year contracts typical for the named enterprise clients. The customer base is concentrated in oil and gas operators (PTTEP, Shell, Equinor, Gassco) with active expansion into offshore wind, power cables, maritime/vessel hull repair, and dual-use defense applications. Geographic footprint spans Norway (HQ), Southeast Asia (Thailand, via PTTEP), and the United States (via the Hacking 4 Allies defense program). The company closed a €12M seed round in July 2025 co-led by NATO Innovation Fund and Investinor, with leadership under CEO Christopher Carlsen and CTO Torgeir Bræin.

- Kongsberg Maritime: Norwegian-headquartered provider of subsea robotics, AUVs, and marine systems (part of Kongsberg Gruppen, distinct corporate entity from Kongsberg Ferrotech but sharing the Kongsberg ecosystem). Comparable as a regional subsea robotics leader and potential acquirer/partner rather than direct competitor.
Direct peers
- Soil Machine Dynamics (SMD): UK-based manufacturer of subsea robotic vehicles, ROVs, and trenchers for offshore energy, telecom, and defense. Comparable as a peer subsea robotics OEM with overlapping target markets (pipelines, cables, offshore wind foundations) and similar hardware-centric business model.
- Saab Seaeye: One of the world's largest manufacturers of electric underwater robotic systems (ROVs) for inspection, intervention, and survey. Directly comparable as a provider of subsea robotic platforms serving oil and gas, defense, and hydrographic end markets, though focused on ROVs rather than habitat-based repair robots.
