The mooring operation plays an important role in the operation of ships, and offshore operations need to be equipped with sturdy and reliable mooring winches. Mooring winch will work effectively when the ship is berthed or docked, and has many functions such as drift, support and positioning during loading and unloading, and at the same time, it can adjust and compensate for the deviation caused by vibration with a constant tension.
Common Mooring Methods Used for Ships
There are several common mooring methods used for ships to secure them to a dock or anchor them in place.
- Single Point Mooring: In this method, a single mooring line is used to secure the ship to a mooring buoy or a fixed point on the dock. The line is attached to a bollard or cleat on the ship and then connected to the mooring point. Single point mooring winch is commonly used for smaller vessels or in calm conditions.
- Double Point Mooring: Double point mooring involves using two mooring lines to secure the ship. Each line is attached to a separate bollard or cleat on the ship and then connected to two different mooring points on the dock or buoys. This method provides increased stability and prevents the ship from swinging or rotating.
- Four Point Mooring: Four point mooring system utilizes four mooring lines, with two lines attached to the bow (front) of the ship and two lines attached to the stern (rear) of the ship. The lines are connected to separate mooring points on the dock or buoys, forming a square or rectangular configuration. Four point mooring winch system provides greater stability and control, especially in adverse weather conditions.
- Multi-Point Mooring: Multi-point mooring involves using multiple mooring lines attached to various points on the ship and connected to multiple mooring points on the dock or buoys, such as 6 point mooring, 8 point mooring, 12 point mooring and more. The multi-point mooring winch system is commonly used for larger vessels or in areas with strong currents or high winds. It provides enhanced stability and control over the ship’s position.
These are some of the common mooring methods used for ships. The selection of the appropriate mooring method depends on various factors such as the size and type of the ship, environmental conditions, available infrastructure, and specific operational requirements.

Features And Options Of Aicrane Ship Mooring Equipment
In addition to the main components of a mooring winch system, there are several optional features and components available that can enhance its functionality and versatility. Let’s explore these in more detail:
- Electric and Hydraulic Drive: Our mooring winches can be equipped with either an electric or hydraulic drive system. Electric drives are commonly used and offer precise control, ease of operation, and lower maintenance requirements. Hydraulic drives, on the other hand, provide high power and torque, making them suitable for heavy-duty applications.
- Manual or Hydraulic Clutch: The clutch is responsible for engaging and disengaging the winch drum. Mooring winches for ships can come with a manual or hydraulic clutch option. Manual clutches require manual intervention to engage or disengage the drum, while hydraulic clutches offer smoother and more convenient operation.
- Single Drum and Double Drum: Mooring winches for ships can have a single drum or double drum configuration. Single drum winches are suitable for simple mooring operations, while double drum mooring winches allow for more complex tasks such as simultaneous mooring and towing operations.
