What Schoenrock Hydraulik does
Schoenrock Hydraulik Marine Systems GmbH is a privately held German manufacturer of hydraulic and electric watertight door, shell door, hatch, and ventilation-closure systems for the global maritime industry, headquartered in Tornesch, Schleswig-Holstein. Founded in Hamburg in the early 1950s by Johann Schoenrock as a steel construction shop, the company pivoted to maritime hydraulic actuation by 1955 and was reorganized into its current legal form in 2003; it relocated to an 8,000 sqm facility with 3,800 sqm of production space in late 2018. The product portfolio centers on the SHIPTIGHT (hydraulic and electric, up to 60m water column), PRESSURETIGHT (up to 62m water column), SHOCKTIGHT (naval shock-tested per BV230/Stanag 4141/MIL-S-901D), and FLOODTIGHT door families, supplemented by hydraulic hatches, shell doors, ventilation duct closing systems, the FLEXIMOD operation panel, and a laser safety strip. Manufacturing is integrated in-house, including 5-axis CNC machining, proprietary hydraulic power-pack production, and pressure testing under an ISO 9001:2015 quality system.
The company sells custom-engineered, quote-priced equipment to enterprise naval and commercial shipbuilders worldwide, including Damen Schelde Naval Shipbuilding, Lürssen, Meyer Werft, ThyssenKrupp Blohm+Voss, Howaldtswerke-Deutsche Werft, Flensburger Schiffbaugesellschaft, Fincantieri, Navantia, Samsung, Hyundai, and Mitsubishi. Its largest recent contract is the German Navy F126 frigate program (Damen-led, four ships, double-digit-million-EUR value, deliveries from 2024). Distribution combines direct enterprise field sales with a global agent and service-center network (e.g., IKAD Engineering in Australia, GBI International in Korea), and lifecycle revenue is augmented by worldwide spare-parts delivery and third-party-compatible repair and maintenance services.
All major maritime classification societies — ABS, Bureau Veritas, CCS, DNV, Lloyd Register, RINA, Russian Maritime Register of Shipping, and Türk Loydu — have issued type approvals for Schoenrock products, and the company also holds EC MED Module D certification (valid until 2030) and welding workshop approval. The firm operates with approximately 60 employees under Managing Director Arno Haase-Camper (succeeding Dr. Volker Behrens), is privately held with no external institutional investors or subsidiaries disclosed, and serves shipyards across Europe, the Middle East, East Asia, Southeast Asia, and South America.
