Okeanus Science and Technology, LLC (Okeanus) acquired a custom DT Marine 125-hp electric-hydraulic Slip-Ring Tow Winch, model DT-3125. The custom-designed winch is spooled with over 6,000 m (20,000 ft) of 0.68” UNOLS coax cable. The system is configured to support a wide variety of oceanographic, survey, and scientific equipment and is ideally suited for various deepwater tow sled operations.

The winch’s bare drum line pull is over 20,000 lbs at 0 to 150 ft/min. The drive system consists of a 125-HP, 480 VAC, 3-phase, 650-HZ, totally enclosed, fan-cooled electric motor driving a hydraulic pump that, in turn, drives a hydraulic motor connected in open loop configuration. The hydraulic motor is coupled to the drum through a planetary gear reducer that is attached directly to the winch drum. A multiple disc, fail-safe brake is incorporated into the final drive and located between the hydraulic motor and the gear reducer. The hydraulic reservoir is supplied with a sight level gauge and drain plug contained in the base of the winch such that, except for having to be supplied with outside electric power, the unit is self-contained. The DT-3125 is controlled by a self-centering, single lever, four-way control valve, with metering spool that affords variable speed in both directions, and is located on a sloping panel on the drive component housing. The winch is also equipped with a remote output that allows for the winch to be controlled from any point on the vessel.
