16–150 kN Diesel Engine Driven Marine Winch | Single Drum Wire Rope Deck Winch

16–150 kN Diesel Engine Driven Marine Winch | Single Drum Wire Rope Deck Winch

Product Overview

This diesel engine driven marine winch is a single-drum wire-rope deck machinery unit for controlled hauling, paying out, and holding duties on workboats, barges, utility vessels, dredging support craft, and other marine service vessels. The diesel prime mover allows the winch to operate independently of the vessel’s main electrical supply, which is useful where electrical capacity is limited or where a self-contained deck machinery power package is required.

The updated product range is described by rated line pull from 16 to 150 kN, reference rope speed from 9 to 16 m/min, rope capacity from 120 to 200 m, and reference wire-rope diameter from 12.5 to 32 mm. Selection should not be made from line pull alone: rope construction and minimum breaking load, first-layer drum pull, drum storage geometry, brake holding requirement, duty cycle, vessel arrangement, foundation strength, and classification requirements should be confirmed before the final design is released.

Quick Specifications

• Rated line pull: 16–150 kN → upgraded range for marine wire-rope deck winch selection; final rating should be stated at the defined drum layer.

• Rated rope speed: 9–16 m/min → model-dependent hauling speed; required speed should be checked together with line pull and duty cycle.

• Reference rope capacity: 120–200 m → storage capacity depends on rope diameter, drum dimensions, usable flange height, and permitted spooling layers.

• Reference wire-rope diameter: 12.5–32 mm → rope construction, grade, termination, and minimum breaking load must be confirmed for the project.

• Drive: diesel engine → independent prime mover; final engine rating, gearbox ratio, clutch arrangement, cooling, exhaust, and fuel system are project-specific.

• Configuration: single drum with optional single warping end → compact arrangement for wire-rope storage/hauling with auxiliary rope handling where specified.

• Control: local control as base configuration → remote control, instrumentation, or load/length/speed indication should be specified only when required.

• Construction and coating: fabricated mild-steel winch structure with Sa 2.5 blast preparation and project-specified marine epoxy coating system.

Main Technical Parameters

Selection & Inquiry Guide

Step 1: Define the marine winch duty: anchoring support, utility pulling, deck-handling task, expected line load, operating depth/route, and whether the duty is intermittent or frequent.

Step 2: Confirm rated line pull, required hauling speed, wire-rope construction, rope diameter, rope MBL, total rope length, and required drum storage layers.

Step 3: Confirm diesel drive package: engine make/model if specified, rated output, gearbox/reduction ratio, clutch arrangement, cooling method, exhaust routing, and fuel supply.

Step 4: Confirm brake and operating requirements: brake holding load, controlled payout requirement, local/remote control, emergency stop, instrumentation, and any load/length/speed monitoring.

Step 5: Confirm deck installation: available footprint, drum orientation, rope lead direction, foundation drawing, deck reinforcement, access for maintenance, and shipyard welding/bolting interface.

Step 6: State vessel type, classification society, certificate/inspection scope, coating system, quantity, delivery destination, required delivery date, and provide GA drawing or reference photos when available.

Drive, Transmission & Power Package

• The diesel engine is the prime mover and avoids dependence on the vessel’s main electrical supply during normal winch operation.

• The final reduction system must match required drum torque and rope speed; gearbox ratio and drive arrangement should be based on the selected line pull and drum core diameter.

• Engine output should include transmission losses and the required operating margin. It should not be inferred directly from electric-motor data copied from another winch series.

• Cooling air/water arrangement, exhaust discharge, fuel supply, guarding, hot-surface protection, and maintenance access must suit the vessel installation.

• If a diesel-hydraulic transmission is selected instead of direct mechanical drive, hydraulic pump, motor, relief setting, piping, oil cooling, and emergency functions should be confirmed separately.

Drum, Wire Rope & Warping End

• Single drum configuration provides one dedicated wire-rope storage and hauling drum, reducing deck footprint compared with multi-drum arrangements.

• Rated line pull should be defined at a stated drum layer because effective drum radius increases as rope builds up on the drum and available line pull changes accordingly.

• Rope capacity must be checked from actual drum barrel diameter, flange diameter, rope diameter, fleet angle, and allowable number of layers rather than nominal length alone.

• Wire-rope MBL, construction, grade, termination, and connection to the working arrangement should be confirmed as part of the complete deck machinery package.

• The warping end may be used for auxiliary rope handling only within its designed duty; its capacity should not be assumed to equal the main drum line pull without confirmation.

Brake, Control & Safety Considerations

• The brake should be selected from the required holding load and payout duty, with brake capacity confirmed by calculation and project/class requirements.

• Controls should provide clear haul / stop / pay-out functions and an accessible emergency stop. Control philosophy must match the approved drive arrangement.

• Rotating shafts, couplings, gears, hot engine surfaces, and other hazardous moving or hot parts should be guarded where personnel can access them.

• Foundation bolts or welded seating, base-frame stiffness, deck reinforcement, and rope lead reaction forces should be checked by the vessel designer or shipyard.

• Load monitoring, rope-length indication, rope-speed indication, spooling devices, remote control, and additional interlocks can be considered when required by the project, but are not stated as standard supply without confirmation.

Custom Attributes

Rated Rope Speed: 9–16 m/min → model-dependent speed under the specified operating condition.

Rope Capacity: 120–200 m reference range → final capacity depends on rope and drum geometry.

Wire Rope: 12.5–32 mm reference diameter → construction, grade, MBL, termination, and length required for final selection.

Drive Type: Diesel engine → engine rating and transmission arrangement to be confirmed by drive calculation.

Drum Type: Single drum → one wire-rope storage / hauling drum.

Warping End: Optional single warping end → auxiliary rope-handling function subject to confirmed design capacity.

Control: Local as base reference → remote control and monitoring available only according to project requirement.

Material: Mild-steel fabricated structure → material grades and traceability according to approved design and project requirements.

Surface Treatment: Sa 2.5 blast preparation + marine epoxy coating system → coating build-up and DFT to be confirmed by project specification.

How It Works

Diesel engine starts and supplies mechanical power → transmission reduces speed and increases drum torque → single drum hauls or pays out the wire rope → brake controls and holds the drum when required → optional warping end provides auxiliary rope handling within its approved duty → the wire-rope system is secured according to the vessel’s operating procedure.

Applications

Workboats | Barges | Utility vessels | Dredging support craft | Small and medium service vessels | Project-specific wire-rope deck handling | Vessels with limited electrical power availability

FAQ

Q1: Is this winch the same as an offshore anchor-handling winch used on an AHTS vessel?

A1: Not automatically. This page covers a diesel-driven marine wire-rope winch. Offshore anchor-handling winches used to deploy, recover, or reposition subsea anchors and mooring lines are subject to a different operational and regulatory scope. If that duty is required, it must be stated at inquiry stage and the winch design and certification scope must be reviewed accordingly.

Q2: How should the correct 16–150 kN model be selected?

A2: Start with the required first-layer line pull and operating duty, then confirm wire-rope MBL and diameter, rope length, hauling speed, drum storage geometry, brake holding load, diesel engine package, and deck installation. The listed line-pull range is not sufficient by itself for final selection.

Q3: Can the diesel engine power be copied from a generic winch webpage?

A3: No. Diesel engine power should be checked from required line pull, rope speed, drum radius, transmission efficiency, service duty, and gearbox arrangement. The table in this page uses a consistent calculation basis only for preliminary selection.
