NIPPON PUSNES

What NIPPON PUSNES does

NIPPON PUSNES CO., LTD. (日本プスネス株式会社) is a privately held Japanese manufacturer of marine deck machinery, headquartered in Shimonoseki, Yamaguchi Prefecture, with 124 employees and an operating history tracing back to 1937 through its predecessor Setouchi Iron Works (瀬戸内鉄工所), with the current joint-venture company established in 1976 in partnership with Norway-based Pusnes AS. The company designs and manufactures custom-engineered windlasses, mooring winches, and a portfolio of ancillary winches (ramp, hatch cover, capstan, dredging, crane ship, offshore structure mooring) for commercial shipping, shipbuilding, offshore energy, and specialized work vessel customers worldwide, with approximately 3,500 vessels equipped over its history and a self-described 50% domestic market share in deck machinery for vessels of 50,000+ DWT and above. Core technology encompasses high-pressure hydraulic deck machinery and inverter-driven electric deck machinery, with proprietary features including auto-tension control via constant pressure, high-capacity brake systems exceeding 100-ton holding force, automated robot welding, and 5-sided machining centers capable of handling 30-ton components. All products are custom-built per customer specifications.

Revenue is generated primarily through direct B2B sales of new equipment to shipyards and shipping companies (hardware sales) plus recurring aftermarket services including inspection, repair, maintenance, and spare parts supply through a global service network spanning more than 30 countries, supported by three dedicated service partners in China, Japan/Dubai, and Singapore plus company technicians. Pricing is quote-based per vessel, not publicly disclosed. Distribution is direct enterprise field sales from design consultation through delivery, with global after-sales technical service provided at ports worldwide. The April 2024 merger consolidated the company with its manufacturing subsidiary, integrating the long-standing two-pillar structure into a single entity under the NIPPON PUSNES name. Certification posture includes ISO 9001 (quality, 2000), ISO 14001 (environmental, 2015), and ClassNK welding qualification. The company is led by President and Representative Director Masato Hori (堀 雅人).

Product overview

NIPPON PUSNES is Japan's leading manufacturer of marine deck machinery, producing windlasses and mooring winches as its core products. The company operates a two-pillar structure combining manufacturing expertise from Setozaki Iron Works (est. 1937) and global sales from Nippon Pusnes (est. 1976). The product portfolio centers on two main categories: Windlasses for anchor handling and Mooring Winches for vessel mooring operations, each available in both hydraulic and electric drive systems. Supporting products include ramp winches, hatch cover winches, capstans, and specialized winches for dredging vessels and crane ships. Additional offerings include pump stations as hydraulic power sources and custom machinery such as road surface durability testing devices. All products are custom-manufactured per customer specifications, with approximately 3,500 vessels served and 50% market share for deck machinery on ships over 50,000 DWT.

Products and services

• Windlass (ウインドラス) Marine windlass used for raising and lowering anchors on ships; typically installed in pairs at the bow of vessels. Maximum lifting capacity reaches approximately 82 tons for standard commercial vessels, with chain brake holding force reaching about 520 tons. Units can exceed 3 meters in height and weigh up to 30 tons. Available in both hydraulic and electric drive systems.
• Mooring Winch (ムアリングウインチ) Marine mooring winch for paying out, hauling in, and holding mooring ropes when vessels are docked at quays. Maximum pulling capacity is about 35 tons with rope diameter up to 8cm. Brake holding force can exceed 100 tons per rope. Available in both hydraulic and electric drive systems.
• Ramp Winch (ランプウインチ) Winch for raising and lowering bridge-type ramps on car carriers and RORO ships, enabling vehicles to drive from quay into vessel holds. Equipped with special safety devices for safe ramp holding.
• Hatch Cover Opening/Closing Winch (ハッチカバー開閉ウインチ) Winch used as driving device for side-rolling type hatch covers that slide left and right to open/close cargo holds on bulk carriers transporting coal, iron ore, and other bulk cargo.
• Capstan (キャプスタン) Vertical winch originally used for anchor operations, now primarily used for auxiliary rope handling by crew. Features barrel-shaped drum design allowing continuous use as rope naturally winds to smaller diameter center. Ranges from under 1 ton to over 10 ton pulling capacity, available in both hydraulic and electric drive.
• Dredging Vessel Maneuvering Winch (浚渫船向け操船ウインチ) Winch used on dredging vessels for positioning by extending and retracting wires from forward and diagonal aft positions. Custom designs available based on customer requirements.
• Crane Ship Various Winches (クレーン船向け各種ウインチ) Winches for marine crane vessels including main hoist winches for raising/lowering hooks and luffing winches for crane jib movement. Multiple winch types supplied for crane ship applications.
• Ocean Structure Mooring Devices (海洋構造物向け係留装置) Mooring devices for offshore structures including floating oil development facilities. Units with hundreds of tons of lifting capacity are common, featuring advanced safety devices for harsh marine environments.
• Pump Station (ポンプステーション) Hydraulic power source for the company's hydraulic deck machinery, enabling simultaneous and efficient operation of multiple winches. Can also serve as hydraulic power source for other hydraulic equipment.
• Road Surface Durability Testing Device (路面耐久試験装置) Custom non-marine machinery applying the company's expertise in hydraulic and electrical control systems for large machinery. Manufactured based on customer requirements.
