What is a Mooring Winch? A mooring winch is a mechanical device used on ships, docks, and offshore platforms to secure a vessel to a fixed point, such as a dock or mooring buoy. It helps control the tension and release of ropes, cables, or chains to ensure the vessel remains steady and in position during berthing, docking, or while at anchor. We provide wide range of mooring winches to suit various mooring operation needs.

How to Choose the Right Mooring Winch for Ships?
Choosing the right mooring winch for ships is essential for safe and efficient marine operations. Key factors to consider include ship type, load capacity, power source, and environmental conditions. Let’s take a closer look at each factor now.
Ship Type and Size
Para small to mid-sized ships like fishing boats, ferries, and coastal cargo ships, electric single drum mooring winches are ideal. They are easy to install, energy-efficient, and require low maintenance.
Para grandes vasos such as tankers, container ships, and bulk carriers, hydraulic double drum or split drum mooring winches are better suited due to their high power and ability to handle multiple lines.
Capacidad de carga
Consider the load capacity: Electric winches work well for light to medium loads, while cabrestantes hidráulicos are necessary for heavy loads and continuous operation.
Fuente de alimentación
When selecting a power source, mooring electric winches are quieter, eco-friendly, and cost-effective, while hydraulic ones provide more torque and durability for demanding tasks.
Condiciones ambientales
Factor in the environmental conditions: For coastal or harbor use, electric mooring winches are preferred; for offshore and harsh environments, hydraulic winch machines are more robust. In eco-sensitive areas, tornos eléctricos help avoid the risk of hydraulic fluid leaks.
Mooring Winch Price
The price of a mooring winch can vary significantly based on factors such as type, load capacity, drum capacity, configuration, and additional features. Therefore, providing an exact cost without specific details can be difficult. Below is a reference price range for mooring winches:
| Tipo de cabrestante | Capacidad de carga | Precio |
|---|---|---|
| Torno de amarre eléctrico | 5 toneladas - 30 toneladas | $11400 - $48500 |
| Torno de amarre hidráulico | 5 toneladas - 50 toneladas | $15700 - $85700 |
Please keep in mind that these figures are rough estimates, and the actual mooring winch price may vary greatly depending on your specific requirements and winch specifications. For an accurate price, it’s best to contact fabricantes de cabrestantes or suppliers directly with your special needs.
Mooring Winch Parts and Functions
- Tambor: El tambor es el corazón del cabrestante. Es un carrete cilíndrico alrededor del cual se enrolla el cabo de amarre (normalmente una cuerda o cadena). El tamaño y la capacidad del tambor determinan la longitud y la resistencia de la línea que puede acomodar.
- Sistema de frenos: El sistema de frenado es crucial para controlar la tensión y la velocidad del cabo de amarre. Evita que el tambor gire demasiado, lo que garantiza que la línea se manipule de forma segura.
- Motor: El motor del cabrestante proporciona la potencia necesaria para accionar el cabrestante. En los cabrestantes más grandes y potentes se suelen utilizar motores hidráulicos o eléctricos.
- Caja de cambios: La caja de cambios se encarga de transmitir potencia desde el motor del cabrestante al tambor. Contiene un sistema de engranajes que ajustan la velocidad y el par del cabrestante para satisfacer los requisitos de carga.
- Marco/placa base: El marco o placa base proporciona el soporte estructural para todos los componentes del cabrestante. Está diseñado para soportar las fuerzas y cargas encontradas durante las operaciones de amarre.
- Sistema de control: The control system allows operators to control the speed, tension, and direction of the winch. It can be manual, semi-automatic, or fully automatic.
What Is the Purpose of Mooring Winch?
The purpose of mooring winch is to securely anchor and stabilize a vessel during docking, undocking, or while stationed offshore. We mainly explore its primary functions in this part.
Securing the Vessel
- Holds the vessel in position at docks, piers, or offshore platforms, preventing unwanted movement caused by wind, waves, and currents.
Adjusting Line Tension
- Allows for tightening or loosening mooring lines to adapt to changes in water levels, tide, or vessel load, maintaining stability and safety.
Assisting with Docking and Undocking
- Provides controlled line handling to guide the vessel smoothly into or out of port, reducing the risk of damage to the vessel or dock.
Mejorando la seguridad
- Prevents accidents by ensuring mooring lines are secure and under proper tension, reducing the risk of lines snapping or vessel drifting.
Supporting Offshore Operations
- Keeps vessels or floating platforms steady in dynamic environments like oil rigs, where stability is crucial for safe operations.
What Are the Common Mooring Methods?
Single Point Mooring (SPM)
A buoy or a single anchor point to which a ship connects.
Typically used for loading or unloading cargo in deep water away from shore.
Ideal for oil tankers and large cargo vessels.
Multi-Point Mooring
The vessel is secured to multiple fixed points (e.g., bollards on a pier).
Uses lines extending from the bow and stern to prevent movement.
Suitable for various vessel types in harbors or docks.
Mediterranean Mooring (Med Mooring)
The ship approaches the dock stern-first and secures the stern to the quay, while anchors hold the bow.
Common in crowded marinas or ports with limited space.
Alongside Mooring
The vessel is secured parallel to the dock using mooring lines from bow, stern, and midship.
Common for cargo ships, ferries, and passenger vessels.
Fore and Aft Mooring
The ship is secured by lines extending from both the bow and stern to fixed points on the dock or quay.
Used for smaller vessels or where limited berthing space is available.
Difference Between Aft Mooring Winch and Forward Mooring Winch
| Feature | Aft Mooring Winch | Forward Mooring Winch |
|---|---|---|
| Ubicación | Installed at the stern (rear) of the vessel | Installed at the bow (front) of the vessel |
| Función primaria | Secures the aft section of the vessel to the dock or mooring point | Secures the forward section of the vessel to the dock or mooring point |
| Role in Vessel Stability | Helps prevent rearward drift and maintains stern alignment | Helps prevent forward drift and maintains bow alignment |
| Aplicaciones típicas | Used on large ships, tankers, ferries, and vessels requiring rear stabilization | Used on all vessel types, including bulk carriers, cruise ships, and offshore vessels |
| Configuraciones comunes | Single Drum or Double Drum winches | Single Drum, Double Drum, or Split Drum winches |
| Line Handling | Handles lines securing the stern | Handles lines securing the bow |
| Mooring Process | Assists in rearward mooring and undocking | Assists in forward mooring and undocking |
Tips for Mooring Winch Maintenance
- Check drums, brakes, clutches, and motors for damage or wear. Inspect mooring lines for fraying or tension issues.
- Hydraulic Winches: Inspect hoses, fittings, and fluid levels. Electric Winches: Check wiring, connections, and motors.
- Ensure brakes, clutches, and emergency stops function properly.
- Remove salt and debris; apply anti-corrosion coatings. Use protective covers for weather resistance.
- Align drums and gears; calibrate sensors if applicable.
- Follow manufacturer maintenance schedules. Get periodic professional inspections.
