Newthex

What Newthex does

Newthex (Newthex Ned BV) is a privately held Dutch manufacturer specializing in custom-engineered maritime access solutions, headquartered in Kolham, Groningen. The company designs, fabricates, and assembles watertight doors, weathertight hatches, hull and shell doors, helicopter lifting platforms, Ro-Ro ramps, and elevator systems for three primary customer segments: superyacht builders (Benetti, Oceanco, Turquoise Yachts, Heesen, Hakvoort, Baltic Yachts, Conrad, Golden Yachts, Tankoa), naval and defense programs (Royal Netherlands Navy, Indian Navy, Belgian Navy via Damen Naval), and commercial/offshore operators (Damen Shipyards, Van Oord, AirBus A380 logistics). Products are built in steel, aluminium, and composite materials, engineered using SolidWorks 3D design and Cosmos Works structural analysis, and certified by Lloyd's Register, RINA, DNV, and other classification societies to be watertight up to 7m water column.

The business operates on a project-based hardware sales model with custom unit pricing tied to specifications, materials, and certification requirements, supplemented by professional services revenue streams covering engineering/design, after-sales maintenance, spare parts, refits, and crew training. Manufacturing and assembly are consolidated in a single Kolham facility with in-house milling for aluminium and stainless steel components, complemented by Ukrainian engineering partners for capacity scaling. Distribution combines direct enterprise sales with a four-country agent network covering Italy, Turkey, India, and Spain, and customer acquisition is heavily event-driven (Metstrade, Monaco Yacht Show, Superyacht Technology Show, Navy Tech, Seatec, CNR Eurasia, Defense & Security Bangkok). The company holds ISO 9001:2015 and ISO 14001:2015 certifications audited by DNV and owns the patented NEXT single-handle watertight door closing system plus proprietary invisible sliding-tilt hinge technology.

With 14 employees, Newthex is a small but globally active specialist competing in niche maritime access equipment, leveraging patented mechanical IP, classification-society certifications, and shipyard relationships to win contracts on premium superyacht and naval programs across Europe, Turkey, India, and Asia. The company is independently owned with no disclosed institutional investment, no parent company, and no public revenue disclosure.

Scale indicators4 records

Recent moves8 records

Expansion highlights6 records

Broad incumbents

• Wärtsilä: Large Finnish marine systems integrator covering propulsion, decks, and integrated ship solutions. A broad incumbent whose portfolio sits upstream of Newthex and could expand into or absorb specialized access equipment subcategories.
• Viking Life-Saving Equipment: Major marine safety equipment supplier covering lifeboats, davits, and evacuation systems. Not a direct door/hatch competitor, but operates in an adjacent marine safety niche and serves overlapping naval and commercial shipyard customers.
• Survitec Group: Global marine safety and survival equipment incumbent including lifeboats, davits, and firefighting systems. Broader portfolio but overlaps with Newthex in safety-critical access and egress equipment supplied to navies and commercial shipyards.
• KONE Marine Elevators: Global elevator and escalator manufacturer with a marine and offshore elevator line. Overlaps with Newthex's elevator door and cargo elevator business for naval and yacht vessels as a much larger incumbent.

Direct peers

• Bohamet: Polish manufacturer of marine doors, hatches, and windows for naval and commercial vessels. Directly comparable to Newthex in producing custom-engineered metal access solutions and supplying navies and shipyards across Europe.
• Beclawat Manufacturing: UK-based manufacturer of marine doors, hatches, and windows serving commercial and naval shipyards. Competes head-to-head with Newthex in fulfilling specification-driven access equipment orders for shipbuilders.
• Rondal: Dutch supplier of custom superyacht components including mast, rigging, and deck hardware. Comparable as a Netherlands-based, design-led component supplier serving the same superyacht shipyard customers with project-based, high-specification products.
• Bolz Apparatebau: German stainless steel specialist with marine door and hatch products for shipyards. Overlaps with Newthex in custom-engineered marine access hardware, particularly in the European shipbuilding supply chain.

Emerging players

• RH Marine: Dutch system integrator delivering electrical and automation systems for naval and superyacht markets. They are a peer in the Dutch maritime supplier ecosystem serving Damen and similar customers, though not a direct door/hatch competitor.

Others

• HyDAC (Bosch Rexroth Marine Hydraulics): Supplier of hydraulic drive and motion control components used in marine doors, hatches, and ramps. Newthex integrates their hydraulics into products like the helicopter lifting platform, making them an enabling technology supplier rather than a direct competitor.
