Electric mooring winch

electric mooring winch is a piece of the marine machine employed in mooring operations to footing a boat in place at a pier or similar fixture. Such winches can also be able to control anchors for mooring when port devices are not available. They may operate in a number of ways and are fixed in place on the deck of a ship in key positions. The mooring winch has many functions in drifting, supporting and positoning when loading or unloading the materials.

How to Select The Right Mooring Winch?

1. The working load of winch drum

2. Holding load

3. Rope diameter

4. Nominal speed

5. Rope capacity

6. Operating voltage and structural requirements

7. Do you require a rope guide?

8. Do you need an automatic mooring winch?

9. How is the working condition?

10. Do you need a warping end?

11. Do you need a classification society certification?

Technical Requirements of Electric Mooring Winch：

Rope drum

Generally, the safety factor of the cable is 6~8. If no special requirements are specified, the safety factor will be 6. The rope is available in many different types, such as synthetic fiber and wire rope. When using the wire rope, the diameter of the drum is not less than 16 times the designed rope diameter.

Automatic control brake

The electric mooring winch will be equipped with automatic control brake. When the handle is at the brake or the winch is unpowered, this device should automatically brake.

Rope guide

According to the customer’s requirements, rope guide can be fitted on the electric marine winch.

Drum brake

Each winch should be equipped with drum brake for a safe winching operation

The working principle of an electric mooring winch is to convert electrical energy into mechanical energy through a motor, that is, the rotor of the motor rotates and drives the drum to rotate after the V-belt, shaft and gear decelerate.

It uses an electric motor as power, drives the drum through an elastic coupling, a three-stage closed gear reducer, and a gear coupling, and uses an electromagnetic system.

  1. Check the critical components of winch machine prior mooring to make sure they are in good working conditions. For instance, check all controls, rope and drum.
  2. Conduct regular greasing of rotating parts of mooring winch, such as rollers, drum and fairleads.
  3. Conduct visual inspection periodically for damages.
  4. Clear walkway to ensure the deck is completely free of obstructions and oil residues.
  5. Maintain the wire rope regularly to improve its performance as well as extend its life.
  6. Mark and label the winch properly to ensure a safe and effective operation. Specifically speaking, the rotating direction of the drum should be clearly marked; the fairleads and rollers should be marked with their safe working limits; braking capacity shall be marked.

Single-buoy or single-point mooring system:

Generally, larger vessels that cannot approach ports and wharves are moored at port boundaries or shelters, and cargo transshipment is carried out through single-point or single-buoy mooring.

The basic principle of the buoy is to keep the position of the ship stable relative to the buoy, while allowing the ship to swing in the wind.

Conventional buoy or multi-buoy mooring:

In this method, the bow of the ship is fixed with two anchors, while the stern is fixed on the buoy.

Mediterranean mooring:

For this type of mooring, engine motion is used to determine and approximate a pre-calculated position. The bow was initially tilted towards the berth, and the starboard anchor was released at this position.

After that, the engine runs backwards and releases the port anchor at the designated location. The boat leaned back and swung to starboard. Therefore, the ship is secured by two anchors when approaching the dock. Then pass the stern line, keeping the mooring tight by using anchor cables.
