Product Specification

19–70 mm Electric Anchor Windlass & Mooring Winch | Single Gypsy, Single Drum & Warping End

Product Overview

This electric combined anchor windlass and mooring winch integrates a single anchor-chain cable lifter (gypsy), a single rope storage / mooring drum and a warping end on one deck-machinery foundation. The cable lifter handles the anchor chain, while the drum manages the specified mooring rope and the warping end provides auxiliary rope handling. The combined arrangement can reduce machinery footprint and simplify deck integration where one drive package is required to perform both anchoring and mooring functions.

The supplied series covers anchor-chain diameters from 19 to 70 mm, windlass working loads from 15.3 to 208.3 kN after correction of the 70 mm entry, drum mooring pulls from 20 to 150 kN, and rope capacities up to 32.5 mm x 200 m in the provided table. Final selection must confirm anchor-chain grade, anchoring depth, anchor mass, drum rope construction, brake and clutch arrangement, electrical supply, control philosophy, foundation reactions and class requirements. For a combined windlass / mooring winch, ISO 4568:2021 applies to the anchoring function and ISO 3730:2012 is additionally relevant to the mooring-winch function.

Quick Specifications

• Anchor chain range: 19–70 mm → gypsy pocket geometry must match the exact stud-link chain size and approved chain grade.

• Windlass working load: 15.3–208.3 kN → supplied series follows a Grade 2 / A2-type load progression; final duty depends on chain grade and anchoring depth.

• Anchor-chain speed: ≥9 m/min for most sizes, with ≥12 m/min shown for the smallest group → check the approved model and standard duty basis.

• Drum mooring pull: 20–150 kN → this is the rope-drum pull from the supplied configuration, not the mooring-line MBL, WLL, SWL or brake holding load.

• Mooring-rope speed: ≥12–15 m/min → selected together with pull, drum layer, rope diameter and operating duty.

• Rope capacity: 15 mm x 120 m to 32.5 mm x 200 m → capacity is rope diameter x stowage length, not drum diameter.

• Configuration: Single gypsy + single drum + single warping end → combines anchor handling, rope storage / mooring and auxiliary warping in one unit.

• Drive and control: Electric, local control with remote control available → voltage, frequency, motor duty, starting method, protection and emergency-stop logic require project confirmation.

Main Technical Parameters

Selection & Inquiry Guide

Step 1: Confirm anchor chain diameter, chain grade, stud-link standard, anchor mass, maximum anchoring depth and whether a chain stopper is fitted in the approved anchoring arrangement.

Step 2: Confirm required windlass working load, overload / short-term pull, cable-lifter speed, brake holding requirement, clutch arrangement and gypsy pocket details according to class and vessel design.

Step 3: Confirm mooring rope type, diameter, required drum pull, line speed, stowage length, drum layer basis, rope MBL / LDBF where applicable, and whether the drum is intended for storage, working or both.

Step 4: Confirm whether the single gypsy, drum and warping end require independent clutch / brake control, and provide the intended anchor and mooring operating sequence.

Step 5: Provide electrical supply, motor duty, local / remote control requirement, emergency stops, IP protection, ambient conditions, deck layout, line leads, maintenance clearance and foundation information.

Step 6: Confirm class society, FAT / load-test scope, documentation, coating system, quantity, delivery destination and delivery schedule; provide anchor-arrangement, mooring-arrangement and GA drawings if available.

Anchor Handling, Mooring Drum & Control Engineering

• The cable lifter must match the exact anchor-chain diameter, stud-link geometry and chain grade. A nominal chain diameter alone is insufficient for final gypsy manufacture.

• Windlass working load is not a universal fixed value for a given diameter: chain grade and anchoring depth affect the required anchoring duty. The supplied load table therefore needs to be checked against the project chain and depth.

• The gypsy brake, clutch and chain stopper have different functions. The chain stopper and anchoring arrangement should be coordinated so that long-term anchor-chain loads are not assigned to the windlass brake without an approved basis.

• The mooring drum should be selected by rope type, diameter, required pull, working layer and storage length. Pull at the drum is not the same as mooring-line MBL / LDBF or the brake holding capacity.

• The warping end is for auxiliary rope handling and should not be treated as a rope-storage drum. Its profile, diameter and safe line lead should be confirmed for the intended rope.

• Combined machinery can save deck space, but the foundation must transfer anchor-chain forces, drum rope pull, machine torque, brake reactions and dynamic loads into the deck structure. Foundation loads should come from the approved maker drawing.

• Local and remote controls should be arranged for clear visibility of chain and rope leads and should follow the vessel’s safe-mooring philosophy. Control interlocks should prevent incompatible simultaneous operations where required by the design.

• Factory acceptance testing can be specified for the assembled windlass / winch system. ISO 4857:2023 provides a current international reference for windlass and winch FAT procedures when adopted by the project.

Custom Attributes

• Product Type: Combined electric anchor windlass and mooring winch → integrates anchoring and rope-handling functions on one machinery foundation.
• Anchor Chain: 19–70 mm → exact grade, stud-link dimensions and gypsy pocket geometry to be confirmed.
• Windlass Working Load: 15.3–208.3 kN in the corrected supplied series → final requirement depends on chain grade and anchoring depth.
• Cable-Lifter Speed: ≥9–12 m/min → model-specific value to be verified against the selected standard and project requirement.
• Mooring Drum Pull: 20–150 kN → rope-drum operating pull, not line SWL or MBL.
• Rope Capacity: 15 x 120 to 32.5 x 200 mm x m → rope diameter x nominal stowage length from the supplied table.
• Configuration: Single gypsy + single drum + single warping end → clutch and brake arrangement subject to selected model.
• Drive: Electric → voltage, frequency, duty, starter / VFD arrangement, enclosure and space heater to be confirmed.
• Control: Local / remote → emergency stop, interlocks and control-station location according to the approved operating philosophy.
• Certificate Requirement: According to project requirement and subject to class approval → survey, certificate and FAT scope must be agreed before manufacture.

How It Works

Electric motor drives the reduction gearbox → Selected clutch connects the required working element → Cable lifter heaves or pays out the anchor chain / Drum handles and stores the specified mooring rope / Warping end provides auxiliary rope handling → Brake and chain stopper secure the system according to the approved operating procedure → Controls and interlocks manage safe operating modes

FAQ

Q1: How is the correct windlass working load selected for a given anchor-chain diameter?

A1: Chain diameter is only one input. The required windlass duty also depends on anchor-chain grade, anchoring depth, anchor mass and the applicable standard / class rule. The supplied series follows a Grade 2 / A2-type load progression and must be checked if the chain grade or anchoring depth changes.

Q2: Does the 20–150 kN mooring pull equal the mooring-line SWL or MBL?

A2: No. It is the drum operating pull stated for this machinery series. Mooring-line MBL / LDBF, line WLL, drum pull, brake holding capacity and the strength of mooring fittings are separate engineering values and must not be mixed.

Q3: What information is required before confirming a single-gypsy single-drum combined unit?

A3: Provide anchor chain size and grade, anchor mass and depth, required anchoring loads and brake basis, rope diameter / construction / length, drum pull and speed, warping-end duty, electrical supply, control philosophy, class society, deck arrangement and foundation constraints.
