Underwater Winch

OUCO certifications

OUCO underwater winches are custom made to suit your specifications and operational requirements.

Underwater winches are useful for many mission-critical applications. They can be positioned in shallow water, mid-ocean water column, or on the seabed down to 10000 meters. Typical underwater winch features include various level-wind and slip-ring configurations, low-power/power-regeneration options, slack rope prevention, and more.

Additionally, you can request protective cages and skid mounts for safe deployment underwater.

OUCO underwater winches are perfect for scientific research and more.

Applications of Underwater Winches

It is mainly used for launching, recovering and towing underwater probes in the deep sea.

As the necessary equipment for marine scientific research, you can install it on Submersibles, Underwater Platforms or Submerged Buoy. After the communication buoy is out of the water, information and data are transmitted via satellite.

Our Underwater winch can also be used for seabed salvage, deployment of marine science instruments, ROV equipment assistance, and other deep sea operations.

Winch manufacturer process

What is an Underwater Winch?

Underwater winches are carrying out a variety of crucial deep-water responsibilities.

They are positioned on a groundwater platform and installed on the seafloor or within the aquatic environment.

Underwater Winch is applicable for industrial, military, marine, mining, and oilfield.

What are The Features and Capabilities That Every Underwater Winch Should Possess?

There are classifications of prerequisites for both standard and custom Underwater Winch including:

  • Compact
  • Simple Installation
  • Adjustment and Maintenance Simplicity
  • Low Complexity
  • Multiple Cable Layers
  • Surface Piercing Capability
  • Good at lowering load under power
  • Robust Drivetrains
  • Most Efficient
  • Light and Heavy Duty
  • Total Cable Management Systems


  • Stabilizing a remotely operated asset
  • Handling an ROV’s tether framework
  • Launching specialized marine equipment
  • Variety of coating options
  • Salt or freshwater capable
  • Near silent winch layout for submarine equipment
  • Customized keys and cable holder accessories
  • AC and DC hydraulic solutions
  • Depth capabilities
  • Subsea mooring winches
What are The Components of an Underwater Winch?

Underwater Winch will not be formed without its parts, namely the following:

  1. Winch Drum

This is where the rope or chain is wrapped.

  1. Mounting Interface

It serves as the position of screw holes that are located at the side of the underwater winch.

  1. Winch Cable or Winch Rope

These cables spool around the electric winches that are mounted at the back.

  1. Slip Ring Cable

It passes electrical signals and power across a rotating interface using sliding electrical contacts.

  1. Enclosed Drive

It is a barrier or a cover around the underwater winch that serves as protection or privacy.

  1. Cable Fairlead Assembly

This is a device to guide a line rope or cable around an object.

  1. Subsea Frame

It performs operations such as offshore and subsea load handling.

What are The Design Parameters of an Underwater Winch?

An underwater winch is never just an underwater winch, particularly when engineering for failproof subsea preparations.

So here are the parameters to be administered:

  • Line Pull
  • Line Speed
  • Minimum Bend Radius of Cable
  • Cable Diameter
  • Cable Length
  • Water Depth
  • Mounting
  • Length of Deployment
  • Remote Controls
  • Power Budgeting or Optimization (when using battery power)
  • Material Selection
What are The Power Options of an Underwater Winch?

The underwater winch has two power options including:

  1. Hand Powered

It is a manual take-up operation by using a rotating lever.

  1. Powered Motor

It has four types which include the following:

  • Electric Motors

They come with permanent magnets or a variety of wound motors.

  • Pneumatic Motors

It uses flow valves and air compressors to suppress winch speed by diverging airflow.

  • Hydraulic Motors

They are supercharged by controlled hydraulic fluid and alter rotational kinetic energy.

  • Gasoline Powered Motors

Engines are powered by fuel and are accessible for outboard applications.
