What DCN Diving does

DCN Diving B.V. is a family-owned subsea service contractor headquartered in Bergen op Zoom, Netherlands, founded in 1957 by Wim Vriens Sr. and currently in its third generation of family leadership. The company operates as an integrated EPIC contractor (Engineering, Procurement, Contracting, Installation) with in-house engineering capabilities, executing projects end-to-end from concept design through installation and maintenance across three primary segments: offshore oil and gas and renewables, hydro power dams, and civil infrastructure and ports. Its service portfolio spans saturation diving, surface supplied diving, ROV support and survey, underwater concreting, vessel husbandry, dredging and excavation, hyperbaric and wet testing, and the creation of dry space using habitats, cofferdams, and bulkheads.

The company's underlying technology stack centers on a fleet of proprietary and contracted assets, including three ROV platforms (Tomahawk rated to 3000 m, Cougar rated to 1000 m, Falcon for compact missions), saturation diving systems, diving units, vessels (including the recently acquired DSV Picasso), and pontoons. Notable proprietary methods include the award-winning Micro Habitat System for permanent repair of subsea structures and a Self Propelled Sealing system for pipeline rehabilitation. DCN Diving operates from nine country offices spanning Europe, the Middle East, Africa, Latin America, and Southeast Asia, serving enterprise clients in oil and gas, energy, and construction.

DCN Diving's revenue model is project-based, professional services billing for diving and marine support engagements; pricing is not publicly disclosed and quotes are delivered per project. The go-to-market motion is sales-led and direct, relying on enterprise client relationships, project portfolio case studies, and industry event recognition. The customer base is composed of large operators and contractors such as Perusahaan Gas Negara, Allseas, CEPSA, Dana Petroleum, Gas Natural Fenosa, CLP, GDF Suez, and IMMONTEC, with projects often executed in partnership with major construction firms including DEME and Stadsbader Contractors.
