PRODUCT INTRODUCTION

The Marine Mooring Winch is a deck machinery solution purpose-built for managing, holding, and storing mooring ropes on a single drum during vessel berthing, docking, and station-keeping operations. By winding steel wire rope or synthetic lines onto the drum to generate pulling force, the winch functions in manoeuvring, holding, and storing modes to ensure a vessel remains safely secured to quays, platforms, or buoys. Mooring winches are available in electric, hydraulic, and steam-driven configurations, and can be classified as automatic (with built-in tension control to compensate for tidal variations, wind, and cargo-induced load changes) or non-automatic. The rated line pull typically ranges from 5 kN to over 3,000 kN, with drum capacity and line speed tailored to specific vessel types and operational requirements. As a critical part of the ship’s deck equipment, the winch is designed and manufactured in full compliance with international standards such as ISO 3730, ISO 9089, GB\/T 4446-2025, and certified by major classification societies including CCS, ABS, BV, and DNV.

FEATURES

Manoeuvring & Mooring — Pays out and hauls in mooring lines to secure the vessel alongside a quay, buoy, or platform. Rated pull ranges from 5 kN to over 3,000 kN for all vessel types.

Holding & Station-Keeping — Static brake holding capacity ≥1.25× rated pull, maintaining position during loading/unloading and preventing drift due to wind, waves, or currents.

Constant Tensioning — Automatic winches with built-in tension feedback automatically heave or pay out rope to compensate for tide, wind, and draft variations, preventing slack or overload. Particularly suited for high tidal variation ports and offshore installations.

Warping — Moves or adjusts the vessel alongside a quay using an integrated or separate warping head for precise position adjustment during berthing operations.

Safety Protection — Fail-safe brakes, overload relief, and emergency release ensure safe operation under extreme loads or emergency conditions.

Remote Control & Unattended Operation — Supports local control, remote control, and integrated bridge control, with advanced models capable of unattended automatic operation.
