Marine Electric Combined Windlass

Optimize your deck operations with our marine electric combined windlass, an essential piece of deck machinery designed to handle both anchor chain handling and mooring operations in a single, integrated unit. This dual-function system streamlines vessel operations, saves valuable deck space, and provides reliable performance for professional marine applications worldwide.

This electric anchor windlass is engineered to meet the demanding requirements of a wide range of vessels, including:

• Commercial vessels (cargo ships, container ships, bulk carriers)

• Tankers (oil, chemical, and LNG carriers)

• Offshore support boats (OSVs, PSVs, supply vessels)

• Large yachts & naval ships

Our horizontal combined windlass features a robust configuration with one or two anchor chain wheels (gypsies) and one or two mooring drums (or split drums), along with optional warping heads. This versatile ship anchor winch is designed for the safe and efficient deployment and retrieval of anchors, as well as the secure handling of mooring lines when docking.

Driven by a powerful hydraulic drive system (electric drive also available upon request), the unit delivers smooth, controlled power. It is equipped with failsafe manual or hydraulic brakes and manual or hydraulically operated clutches for reliable control. Operation is flexible with both local and remote control options, ensuring crew safety and precise maneuvering.

Key Features & Benefits

• Dual-Function Capability: Combines anchor windlass and mooring winch functions in a single, space-saving unit, reducing deck congestion and equipment costs.

• Versatile Configuration: Available with one or two anchor chain wheels, one or two mooring drums (or split drums), and optional warping heads to suit specific vessel layouts and operational needs.

• Robust Hydraulic Drive: Features a reliable hydraulic drive system for smooth, controllable power with excellent low-speed torque for precise anchor handling.

• High-Strength Materials: Constructed from heavy-duty materials to withstand the extreme loads and corrosive conditions of marine deck machinery.

• Reliable Braking System: Equipped with failsafe manual or hydraulic brakes to ensure secure holding of the anchor and mooring loads at all times, even during power loss.

• Flexible Control Options: Offers both local controls on the unit and remote control capabilities (from the bridge or deckhouse) for safe and convenient operation.

• Comprehensive Range: Available in models DMA-17.5 through DMA-50 to accommodate anchor chain diameters from 17.5mm to 50mm (AM2 and AM3 grades).

Frequently Asked Questions (FAQ)

1. What is the difference between a windlass and a combined windlass?
A standard windlass is designed primarily for handling the anchor chain (gypsy wheel). A combined windlass, like our DMA series, integrates both an anchor windlass and one or more mooring drums onto a single base. This allows the same unit to handle both anchoring duties and the mooring lines used for docking, providing a more efficient and space-saving deck machinery solution.

2. What does “horizontal combined windlass” mean?
“Horizontal” refers to the orientation of the shaft. In a horizontal combined windlass, the main shaft is mounted horizontally, with the anchor chain gypsy and mooring drums mounted side-by-side on this shaft. This configuration is common on larger commercial vessels and provides a stable, powerful, and easily serviceable arrangement for handling heavy loads.

3. What are AM2 and AM3 anchor chain grades?
AM2 and AM3 refer to grades of anchor chain as defined by classification societies. AM2 is a high-strength steel grade commonly used for general-purpose anchoring. AM3 is an even higher strength grade, offering greater tensile strength for the same diameter. Our windlasses are designed to handle both grades, with working load and overload capacities specified for each in the technical table.

4. What control options are available for this windlass?
We offer flexible control solutions to suit different vessel bridge and deck layouts:

• Local Control: A control panel mounted directly on or adjacent to the windlass for hands-on operation during maintenance or emergency use.

• Remote Control: Allows the windlass to be operated from a remote location, such as the wheelhouse or a deck control station, providing better visibility and crew safety during anchoring and mooring operations.

5. How do I select the correct DMA model for my vessel?
The primary selection factor is the size (diameter) and grade of your vessel’s anchor chain. Choose the DMA model that matches your chain diameter (e.g., DMA-30 for 30mm chain). You must also ensure that the unit’s working load (for both AM2 and AM3 grades) exceeds the maximum expected load during anchor retrieval. The drum capacity and mooring line load should also be checked against your mooring line specifications.
