What Delmar Systems does

Delmar Systems, operating commercially as Vryhof, is a privately held offshore engineering and equipment company providing total mooring solutions to the global offshore energy industry. Founded in 1968 and headquartered in Houston with primary operating entity Delmar Systems AS in Norway, the company designs, manufactures, rents, and installs proprietary anchoring and mooring systems, including drag-embedment anchors (STEVPRIS Mk5/Mk6, STEVSHARK REX, STEVMANTA), chain adjusters and tensioners (STEVADJUSTER, STEVTENSIONER), quick-release systems (RAR Plus), and supporting software (DELTRACKER). It delivers turnkey services spanning FEED engineering, equipment procurement, offshore installation and retrieval, asset management, and marine supervision to drilling contractors, oil and gas operators, floating wind developers, dredging contractors, and aquaculture operators.

The company's revenue model combines equipment rental (anchors, chains, fiber ropes, connectors, buoyancy), project-based installation and engineering services, and asset management subscriptions. Pricing is project-specific and quote-based. Customer concentration is enterprise-only, with multi-year framework agreements (e.g., Diamond Offshore's 10-year partnership for mooring equipment and co-development of its Mooring Integrity Management System) and named engagements with majors including Lundin Energy, OMV, Woodside, Maersk Drilling, Saipem, and Perenco.

The business operates across offshore oil and gas drilling and production (primary verticals), with growing exposure to marine renewables (floating wind, tidal), dredging, and aquaculture. Geographic coverage spans North America, Europe (notably Norway and the Netherlands), Asia Pacific (Australia, Singapore, Malaysia, Indonesia), Africa (Nigeria, Congo, South Africa), the Caribbean, and the Middle East. The September 2024 acquisition of IKM Mooring Services and a 2019 Singapore manufacturing partnership with Franklin Offshore/CFE Engineers indicate an active inorganic and geographic expansion strategy.

Products and services

• RAR Plus Releasable Mooring System Next-generation mooring release technology that lets MODUs disconnect from moorings without AHTS vessel assistance. Features independent mechanical backup release for 100% redundancy, 907 tonnes minimum break load certified by DNVGL and ABS, and over 1,000 successful mooring line releases on 100+ rigs in the last 4 years.
• STEVSHARK REX Anchor Revolutionary drag-embedment anchor with radical new fluke and shank geometries that delivers up to 47% more holding power than previous anchors in hard soil conditions such as limestone, calcarenite and very dense sands. Available in 3 to 60 metric ton versions for oil & gas, dredging, offshore construction and marine renewables.
• STEVPRIS Mk6 Anchor Industry standard drag anchor with over 8,000 units employed over three decades. Combines fluke design from STEVMANTA and robustness of STEVPRIS Mk5 to deliver well over 30% more holding power than other drag anchors, used for drilling rigs, FPSOs, SPM buoys, dredging, and floating wind turbines.
• STEVPRIS Mk5 Anchor Drag anchor introduced in 1993 that became the most used drag anchor for larger mobile and permanent moorings, generating up to 50 times its own weight in holding capacity, with over 2,200 anchors still in operation worldwide.
• STEVMANTA Vertical Load Anchor Vertical Load Anchor (VLA) for taut leg mooring systems that provides 3.5x holding power versus pull-in load, transitions from installation drag mode to vertical mode automatically, and is designed for ultra-deepwater applications as the lightest and smallest deep water anchor available.
• STEVIN Anchor Original Vryhof anchor design that outperformed all existing anchors at its inception, originally designed for the dredging industry and serving numerous applications, still available though replaced by later designs.
• STEVSHARK Anchor Adapted version of STEVPRIS Mk5 for hard soils such as limestone, calcarenite, very dense sands and coral, with stronger construction, shark teeth, sharp fluke edges and tips and an optional hollow fluke that can be ballasted for initial penetration.
• STEVADJUSTER Subsea Chain Adjuster Innovative cost- and time-saving subsea solution for chain adjustment, pre-tensioning of moorings and easy connection or disconnection of anchor lines. Entire operation takes place subsea without requiring winches or heavy equipment on the platform, with significant safety benefits by performing tensioning away from the floater.
• STEVTENSIONER Chain Shortening Clutch Chain shortening clutch for subsea tensioning that reduces required load by up to 60%, used for proof loading of permanent mooring systems for CALM buoys and FPSOs, handles loads up to 1,250 tons and accommodates chain sizes of 76-152mm, available on rental basis with engineering and supervision.

Direct peers

• InterMoor: InterMoor (an Acteon company) is one of the largest dedicated offshore mooring and subsea installation services providers, offering rig mooring, FPSO mooring, and mooring inspection services - directly competing with Delmar Systems/Vryhof in MODU and permanent mooring scopes globally.
• SOFAR (formerly Single Buoy Moorings-related suppliers): SOFAR Ocean develops ocean data platforms using drifting buoys and moored autonomous vehicles; adjacent mooring and positioning technology provider overlapping in oceanographic/instrument mooring use cases relevant to Delmar's positioning systems.
• Balko Technologies / Bridon-Bekaert: Bridon-Bekaert (a combined entity of Bridon and Bekaert's ropes business) supplies mooring chains, wire ropes, and synthetic fiber rope systems used in offshore mooring applications - directly complementary and partially competing with Delmar's MOORLINK swivels and Seafloor Safe fiber rope products.

Broad incumbents

• Bourbon (offshore support vessels): Bourbon operates a global fleet of offshore support vessels (AHTS, PSVs, crew boats) serving the same drilling contractor and operator customer base. While Delmar's RAR Plus specifically eliminates AHTS dependency for unmooring, Bourbon and similar vessel operators represent both customers and competitive pressure on project execution.
• Subsea 7: Subsea 7 is a tier-1 subsea contractor delivering SURF and IRM solutions to offshore oil and gas operators. As a primary contractor on many EPCI scopes that bundle mooring installation, Subsea 7 is both a potential partner and a competitive threat to niche mooring specialists like Delmar.
• Oceaneering International: Oceaneering provides mooring, intervention, and subsea hardware solutions including chain and wire rope systems. Competes with Delmar/Vryhof in permanent and temporary mooring scopes and has broader umbilicals, ROV, and tooling offerings.
• Acteon Group: Acteon Group is the parent of InterMoor and a broader offshore services group. As a portfolio operator in mooring, foundation, and subsea services, Acteon competes directly via InterMoor and is a relevant comparable for Delmar's multi-service mooring model.
• SBM Offshore: SBM Offshore designs and operates FPSO, FLNG, and FSO vessels with proprietary turret mooring systems. As a buyer/integrator of permanent mooring anchors and chains, SBM is both a major customer for and adjacent competitor to Delmar's FPSO mooring scope.
• DOF Subsea: DOF Subsea provides offshore vessel-based subsea installation, IMR, and mooring services globally. Overlaps with Delmar's offshore crew and installation/retrieval services and competes for similar drilling contractor and FPSO operator clients.

Emerging players

• Miros Group (mooring monitoring): Miros supplies mooring line monitoring and motion measurement systems for offshore assets. Overlaps with Delmar's DELTRACKER and ADAPS positioning technology and competes in the digital monitoring slice of mooring integrity management.
