What Wolfard & Wessels does

Wolfard & Wessels Werktuigbouw B.V. is a Dutch engineering contractor, founded in 1936 and headquartered in Hoogezand, Netherlands, specializing in turnkey piping projects for the maritime sector. The firm serves shipyards, luxury yacht builders (Feadship, Oceanco, Royal Huisman, Lürssen, De Vries Scheepsbouw), and commercial shipping operators across newbuild, refit, and engine room installation projects. Its product portfolio centers on Ballast Water Treatment Systems (UV and electrocatalysis, with 80+ D-2 standard vessel refits), scrubber installations for sulfur compliance, double-walled fuel systems approved by Lloyd's Register, and complete engine room piping installations. Underlying capabilities include a 4000 m2 in-house production facility with CNC pipe bending, T-Drilling, and tube end forming, plus a PipeCloud MES-based digital prefabrication workflow adopted in June 2026.

The business model is project-based, quote-driven turnkey delivery combining engineering services, prefabrication, on-site installation, and lifecycle service and maintenance. Customers engage Wolfard & Wessels via a co-makership model with a single point of contact from 3D scanning and engineering through commissioning. Revenue streams are diverse across newbuild piping, BWTS and scrubber retrofits, propulsion and engine installations, service and maintenance, HVAC (entered 2024), and resale of ELWA electric heating products (since November 2019). The firm is privately held within the SALOR-groep (Salor Spakenburg B.V.) holding structure, operates primarily in the Netherlands and Northern Europe with selective international reach, and holds Lloyd's Register and DNV class certifications that qualify it for regulated maritime piping work.
