What Vryhof does

Vryhof, operating commercially as Delmar Systems, designs, manufactures, and supplies drag anchors and a full range of mooring and anchoring equipment for large floating structures in the global offshore energy industry. The portfolio spans multiple product families — drag anchors (OMNI Max, STEVIN, STEVMANTA, STEVPRIS MK5/MK6, STEVSHARK/STEVSHARK REX), the STEVADJUSTER subsea chain adjuster, STEVTENSIONER installation equipment, the MOORLINK swivel suite (anchor handling, ball, float, installation, mooring chain variants), Seafloor Safe Fiber Rope, the proprietary RAR Plus acoustic quick-release technology, and DelTracker software. Together these cover the full mooring system lifecycle from anchor through connector, release, and digital monitoring.

The technology heritage is anchored in 40+ years of acoustic release know-how, with RAR Plus positioned as the only proven non-assisted release system used by rigs to disconnect from moorings without Anchor Handling Tug Supply (AHTS) vessel support — a critical capability for storm/iceberg evasion and rig-move efficiency. STEVADJUSTER performs chain adjustment and pre-tensioning subsea using only modest installation or maintenance vessels, materially reducing required bollard pull and platform-side risk.

Vryhof monetizes through four revenue streams: rental of mooring equipment (recurring), direct hardware sales of proprietary anchors/connectors/swivels/releases, professional services (installation/retrieval, offshore crews, asset management, equipment procurement), and engineering services (risk assessment, geotechnical and structural analysis, offshore personnel, project management). Go-to-market is direct enterprise sales to offshore drilling contractors, LNG terminal operators, and floating wind developers, supported by dedicated client portals (equipment tracking and document login) and case-study-led content. Pricing is quote-based for custom mooring solutions and is not publicly disclosed. The company is privately held and headquartered in Capelle aan den IJssel, Netherlands.
