What Ocean Group does

Ocean Group is a Kaohsiung, Taiwan-based manufacturer of custom yachting equipment and marine hardware, founded in 2003 by Dutch executive Martyn (Martijn) Castelein. The company serves luxury yacht builders, shipyards, mega yacht owners, and — to a lesser extent — commercial marine operators (tankers, offshore construction vessels). Its portfolio spans electro-hydraulic systems, doors and hatches, stainless steel hardware, pre-built deck units, DNV-certified LED signage, and marine glass, all custom-designed per client specification and project requirements.

The company's core technology combines marine-grade 316L stainless steel and aluminum fabrication with electro-hydraulic system integration and classification-society-certified engineering. Proprietary products include the Z-Lift transom lift system, the Transporter System for tender handling (300 kg to 2-ton capacities), and turn-key plug-and-play shell doors with integrated hydraulic and electrical systems. Materials innovation is demonstrated by super-strength film laminated glass — claimed 100x stiffer than conventional lamination films — enabling weight reductions from 15T to 10T. All hardware is built to DNV and other classification-society standards, positioning certification as a primary deliverable alongside the physical product.

Ocean Group runs a project-based enterprise sales model: quotes are issued per build, there are no public price tiers, and the company sells directly to yards and owners through a dedicated sales team (Sales & Marketing lead Celina Lin, Far East Sales lead Marc Chung). Go-to-market centers on direct enterprise engagement supplemented by participation at Metstrade in Amsterdam (2024 and 2025). The customer base is concentrated in the global luxury and superyacht segment, with active market coverage in Europe, Asia, and the Middle East. A dedicated sub-brand, Z-motion, commercializes the hydraulic lifting product line independently.

Direct peers

• Besenzoni: Italian maker of luxury yacht equipment such as passerelles, boarding ladders, and helm seats, serving the same mega-yacht refit and new-build channels. Highly comparable in product mix, customer base, and emphasis on bespoke finishes.
• Opacmare: Italian manufacturer of hydraulic yacht equipment including transom lifts, passerelles, and side-opening balconies. Directly competes with Ocean Group's Z-Lift, Transporter, balconies, and passerelle product lines for the same superyacht builders.
• Rondal: Netherlands-based superyacht hardware and rig component specialist serving the same Oceanco/Heesen-class new-build segment. Comparable as a custom outfitter focused on high-spec superyacht hardware and finishing.
• MarQuip: Marine crane and lifting specialist supplying tender-handling and deck cranes to commercial and high-end yacht vessels. Directly comparable to Ocean Group's crane and pre-built units product range.
• Pollard Engineering: UK-based custom stainless steel and aluminum fabrication specialist for yacht doors, hatches, and architectural hardware. Comparable manufacturer of bespoke marine hardware with similar finishing and certification requirements.
• Cramm Yachting Systems: Dutch manufacturer of custom hydraulic tender-handling systems and deck cranes for superyachts. Competes head-to-head with Ocean Group's cranes, Z-Lift, and Transporter offering, and shares the Netherlands marine-engineering heritage.
• Tijssen Elektro: Dutch marine electrical and systems integration supplier to superyacht builders. Adjacent competitor on the electro-hydraulic and turn-key systems integration side of Ocean Group's portfolio.

Broad incumbents

• Heesen Yachts: Major Dutch superyacht new-build shipyard and former employer of Ocean Group's founder. While primarily a buyer (customer) of Ocean Group's hardware rather than a competitor, it is a closely related incumbent shaping design, classification, and supplier standards in the segment.

Emerging players

• VeKa Works: Netherlands-based custom stainless and aluminum marine fabricator serving yacht builders. Overlaps with Ocean Group's hull component and door/hatch fabrication work, though at a smaller scale.
• Alumarine: Australia-based marine aluminum fabrication and outfitting supplier to superyacht and commercial vessels. Comparable on aluminum hull structures, hatch, and door fabrication but more regionally focused than Ocean Group's European/Asian footprint.
