Product Description

Mooring Winch from Henan Nucrane

1.Overview
Mooring winch is a key equipment used for mooring operations in ships and marine engineering, mainly used for retracting, tensioning, and fixing cables (such as steel cables, fiber cables, etc.), compensating for deviations caused by vibration through constant tension adjustment, to ensure stable mooring of ships, platforms, or other floating structures at docks, anchorages, or offshore operations, playing a role in drift, support, and positioning. The mooring winches designed and manufactured by our company are widely used in various types of navigation and engineering ships, with working loads ranging from tens of kilonewtons to thousands of kilonewtons.

2.Main Structure and Composition

(1)Drum
-Used for winding cables, usually made of high-strength steel, the surface may have anti slip patterns or coatings to increase friction.
-Divided into single drum, double drum, and multi drum designs, some winches are equipped with storage drums for storing spare cables.

(2)Drive system
-Electric drive: powered by an electric motor, suitable for small and medium-sized ships or scenarios with stable power supply.
-Hydraulic drive: using hydraulic motors, with high power and wide speed range, commonly found in large ships and offshore platforms.
-Diesel drive: used in situations without power supply, such as certain construction ships or remote sea operations.

 

(3)Braking system
-Mechanical brake: In emergency situations, manually or automatically lock the drum.
-Hydraulic brake: Smooth braking is achieved through hydraulic pressure control.
-Dynamic braking: Automatically adjust tension when the load changes.
(4)Tension control device
Real time monitoring of cable tension through sensors and control systems to prevent overload or slack and ensure mooring safety.
(5)Control system
-Local control: The control panel directly controls the operation of the winch.
-Remote control: integrated into the ship's central control system to achieve automated operations.
-Automation functions: such as automatic cable retraction, tension maintenance, collision protection, etc.

(6)Auxiliary components(Optional, customized according to customer needs)
-Fairlead: guides the cable to reduce wear and tear.
-Level Wind: Ensure that the cable is evenly wrapped around the drum.
-Safety devices: such as overload protection, emergency stop button, etc.
 

 

3.Working principle

(1)Cable collection: The drive system drives the drum to rotate, the cable wraps and tightens, and the tension is maintained through the braking system.
(2)Cable release: Control the brake to slowly release the cable, and the tension control system prevents free fall.
(3)Tension maintenance: dynamically adjust the length and tension of the cable according to the external environment (wind, waves, currents).

4.Classification and types of mooring winches in our company
(1)Classify by function and purpose
-Ordinary mooring winch: used for conventional dock mooring.
-Automatic tension adjustment winch: Automatically adjust cable tension according to tides and waves.
-Deep sea mooring winch: used for floating production storage and offloading units (FPSOs), drilling platforms, etc., capable of withstanding extreme environmental loads.
(2)Classify by driving method
-hydraulic mooring winch
-Electric mooring winch
-Diesel driven mooring winch
(3)Classified by installation method
Deck winch: fixed on the deck of the ship.
Embedded winch: integrated with deck structure, can save space.

5.Application scenarios
(1)Commercial vessels: such as container ships, oil tankers, bulk carriers, etc., dock at ports.
(2) Ocean engineering: FPSO, semi submersible platforms, offshore wind power installation ships, etc.
(3)Various fishing boats: Small tonnage, lightweight and diesel power are highly demanded.
(4)Special purposes: scientific research ships, rescue ships, etc.

6. Key parameters for selection
(1) Rated load: usually expressed in tons (T) or kilonewtons (kN), such as 50T, 500kN.
(2)Cable specifications: diameter, length, breaking strength (such as Φ 28mm steel wire rope).
(3)Working speed: Cable retraction speed (meters/minute).
(4)Rope capacity: The total length of cable that the drum can accommodate.
(5) Environmental adaptability: anti-corrosion level (such as IP56), wind and wave resistance.
(6)Various classification society certifications: Our company's products have obtained certifications from international mainstream classification societies such as ABS, CCS, BV, DNV, LR, etc.

7.Advantages

(1)Compact structure, small volume, light weight, and beautiful appearance;
(2) High degree of automation, remote control, and easy operation;
(3)Equipped with overload protection, the braking system is safe and reliable;
(4)Green and environmentally friendly: energy-saving drive system (such as variable frequency motor).
(5)Using high-strength and corrosion-resistant materials, it is sturdy and durable.
