Subsea Winch (Underwater Winch)

Subsea winches for TMS, buoys and arrays
  • Rated to 5000 m — Titanium array / TMS winch for full deep-water operation; 500 m and 1500 m versions for buoys, subsurface moorings and TMS.
  • Constant tension with active pay-out — All configurations hold cable tension and feed cable actively during deployment and recovery.
  • Titanium, aluminum alloy or 316L — Body material selected for depth rating and corrosion resistance.
  • Configured for the payload — Array cable, non-metallic opto-electric cable or metal-armored opto-electric composite cable, sized per project.

Overview Technical Specifications Case Study Download

The Underwater Winch is an electric subsea winch that operates fully submerged. It deploys and recovers ROVs, ROV TMS units, acoustic array cables, buoys, subsurface buoys and sensors in deep water, with a maximum operating depth of 5000 m.

Four base configurations are available: a variable-diameter cable towing winch and a subsurface buoy winch, both rated to 500 m; a buoy / TMS winch rated to 1500 m; and an array / TMS winch rated to 5000 m. All four are electrically driven and combine constant-tension control with an active cable pay-out device.

The body is built in titanium alloy, aluminum alloy or 316L stainless steel according to the depth rating. Cable capacity is specified per configuration, from 350 m of 40 mm array cable to 1800 m of 17.3 mm metal-armored opto-electric composite cable. The winches are designed and supplied by OCEAN PHYSICS and are configured for the ROV, TMS or mooring they serve.
