What Dwellop does

Dwellop Group AS is a Norwegian engineering and manufacturing company headquartered in Tananger that designs and builds bespoke topside handling equipment for offshore well intervention, workover, and plug and abandonment (P&A) operations. Its product portfolio spans wireline systems (Lynx Wire Line Mast, wireline A-frames, winches), coiled tubing equipment (reels, lift frames, jacking frames, hydraulic power units, yard spoolers, reel movers, turntables), modular cantilever and workover rigs, riserless light well intervention (RLWI) boat towers, and P&A-specific rig solutions. The equipment is engineered for harsh North Sea duty, holds NORSOK and DNV classifications, and is differentiated by self-erecting mast architectures, spindle-based injector handling, and skidding systems that reduce crane dependency, eliminate scaffolding, and cut rig-up and rig-down times. The business operates three revenue streams: equipment sales, equipment rental through wholly-owned subsidiary Robust Rental AS (established 2021), and aftermarket service, repair, upgrade, and modification work performed at the Stavanger facility, including on third-party JMC/ODIM/Rolls-Royce legacy equipment. Customers are major oil companies and service providers globally, with public references including Shell UK (Brent C platform, Lynx mast) and Gulf Marine Services (GMS Evolution cantilever system). The company traces its roots to JMC, founded in 1989, was acquired by ODIM in 2007, then Rolls-Royce in 2010, before a 2014 management buy-out established Dwellop; it acquired Phuel Oil Tools in 2023 to broaden its well intervention offering, is listed on the NOTC Oslo under ticker DWLOP, and maintains offices in Norway, Saudi Arabia, and Poland.
