What Delmar & Vryhof does

Delmar & Vryhof provides total mooring solutions to the global offshore energy industry, operating with a 40-year heritage in acoustic release technology under two commercial identities: Delmar Systems (sales and distribution) and Vryhof (engineering and product heritage). The company's offering integrates four revenue layers: equipment rental (anchors, connectors, installation equipment, swivels), mooring services (installation/retrieval, offshore crews, asset management, equipment procurement), engineering services (temporary and permanent mooring design, risk assessment and mitigation, geotechnical and structural engineering, engineering offshore support, project management), and proprietary hardware sales (RAR Plus mooring release, STEVSHARK REX and other anchors, STEVADJUSTER, STEVTENSIONER, MOORLINK swivels, Seafloor Safe Fiber Rope).

The core technology platform centers on RAR Plus, a next-generation acoustic mooring release technology that allows offshore rigs to disconnect from moorings without anchor-handling tug supply (AHTS) vessel assistance — a capability validated by more than 1,000 successful mooring line releases on over 100 rigs in the last four years and 500+ non-assisted releases. Supporting innovations include STEVADJUSTER, a subsea chain adjuster enabling tensioning and connection/disconnection operations entirely subsea without platform-mounted winches or heavy equipment, and DELTRACKER, a software component purpose-built to industrialize floating wind operations. The portfolio is protected by registered trademarks across the anchor family (OMNI Max, STEVIN, STEVMANTA, STEVPRIS MK5 and MK6, STEVSHARK and STEVSHARK REX) and the MOORLINK swivel family (anchor handling, ball, float, installation, mooring chain variants).

Commercially, Delmar & Vryhof runs an enterprise field sales GTM targeting two primary segments — offshore energy operators (oil & gas majors, LNG operators, floating wind developers) and offshore drilling contractors — with named engagements including WindFloat Atlantic (world's first 8.4 MW floating wind turbines), LNG FSU Malta (storm mooring for a floating LNG storage unit), and the TETRASPAR Demonstrator (floating wind industrialization). Pricing is quote-based across complex product-plus-service packages, typical of B2B industrial services, with revenue recognized through equipment rentals (usage-based), professional service fees, and hardware sales. The company is privately held with no public listing, no disclosed funding rounds, no disclosed headcount, and no parent company or M&A activity identified in the source data.
