What Ovun does

Ovun AS, headquartered in Åndalsnes, Norway, designs and manufactures polyurethane and rotationally moulded buoyancy, protection, and electronics-integrated products for over-and-under-water applications. Founded in 1990 (branded as an AIS brand from 2018 and fully acquired by AIS Group in 2025), the company serves seven verticals — Seismic, Offshore Oil and Gas, Renewables, Aquaculture, Hydropower Safety, Marine Navigation and Security, and Customer Solutions — with products spanning surface to 3,000-metre depth ratings, including buoys, floats, cable protection systems, distributed buoyancy modules, and safety barriers. Core manufacturing capabilities comprise rotational moulding using MDPE/HDPE in one of Europe's largest rock & roll ovens, PU moulding qualified to API17L1, in-house electronics development (DTAC remote-control device, PP UW120 underwater generator, AIS/GPS navigation lights), 3D scanning and patterns/moulds, full engineering and design, and a plastic recycling service operated with Nordic Plastics Recycling.

The product architecture is built around two proprietary differentiators: the granted SmartTop steel-free buoyancy armature (PU + Dyneema, NORSOK R002 certified, 20-year service life) and the patent-pending XCS Distributed Buoyancy System for floating wind, which replaces internal clamps with external Dyneema-tethered clamps to materially reduce installation cost and time. Syntactic foam technology and a free end-of-life recycling programme further distinguish Ovun from pure plastics moulders, while sub-brands (Activa for aquaculture, Aqua-Guardian for hydropower safety) carry distinct go-to-market positions.

Commercially, Ovun operates a direct enterprise field-sales model with dedicated vertical sales contacts and downloadable product catalogues; revenue is primarily one-time product sales supplemented by service, repair, and custom engineering contracts under multi-year frameworks with named customers including PGS, Equinor, Subsea7, Nexans, NKT, Statkraft, Vattenfall, the Norwegian Coastal Administration (Kystverket), Kongsberg, Fugro, and Framo. In 2025 AIS Group — a Gloucester-based operator across 14 countries with approximately 800 staff — acquired Ovun, and in March 2026 the group acquired Imenco Aqua and integrated it into the AIS Marine division managed through Ovun in Norway; Advanced Innergy Holdings, AIS Group's ASX-listed parent (ticker AIH), completed a $150M IPO at a $422M market capitalization in October 2025.
