Multimetaal

What Multimetaal does

Multimetaal is a privately held, family-owned Dutch industrial services company founded in 1973 and headquartered at Scheepmakersweg 23, Den Helder — three minutes from Den Helder Airport and six minutes from the seaport, a location purpose-built to support rapid deployment by helicopter or ship to North Sea offshore installations. The company employs 60+ specialists and delivers an integrated portfolio of piping, valve, and metal-construction services for the energy and maritime sectors, spanning custom fabrication, periodic and preventive maintenance, 24/7 emergency repair, pressure safety valve (PSV) testing and certification, inline valve inspection, and decommissioning support for offshore platforms.

The underlying technology stack combines conventional metal-working processes (TIG, MIG, electrode, and 6GR/6GU-position welding; fabrication in (super) duplex, cunnifer, stainless steel, and carbon steel) with newer service capabilities including on-site 3D scanning of offshore connection points, low-heat laser cladding of seal pockets using Inconel 625, and adoption of the Valve Sense acoustic-emission inspection system (Senseven software on i.safe MOBILE explosion-safe smartphones). The business is qualified to ISO 9001, ISO 14001, ISO 3834-2, EN 1090-1, VCA**, Lloyd's T0103/PRD3.2, and is an FPAL-verified supplier — a certification portfolio that gates access to regulated offshore and pressure-safety work.

Commercially, Multimetaal operates a project- and contract-based enterprise services model with no publicly disclosed pricing. Revenue is generated through customer-specific service and maintenance contracts, project-based custom fabrication, 24/7 emergency repair, in-house and on-site valve overhaul, warehousing and stock management of PSVs and spare parts, a Sealweld premium dealership (lubricants, sealants, tools, pumps, and training), and decommissioning services. Distribution is direct enterprise field sales targeting oil & gas operators (Wintershall, TAQA, Neptune Energy, NAM, TotalEnergies, Petrogas, etc.), gas infrastructure owners (Gasunie, Noordgastransport, Fluxys), the Dutch Royal Navy (Koninklijke Marine), and the renewable energy segment (Vattenfall, Energinet.dk on Kriegers Flak). The company is a co-founder of the COP (Cooperating Offshore Partners) one-stop-shop cooperative alongside three other specialist firms, enabling bundled multi-discipline offshore project delivery.
