$25,000.00

1 unit available

Asset Class: Subsea Survey / ROV Handling Systems

​Professional Overview

​Manufacturer: Dynacon, Inc. (Bryan, Texas).

​Model: 421

​Drive Type: Hydraulic (Motor and gear drive configuration needs to be physically verified, as my previous assessment was looking at the ACE winch’s motor).

​Key Features: Integrated diamond-screw level-wind spooling mechanism; open-frame marine design.

​Application: Primary umbilical spooling and handling for work-class ROVs, deep-water towed arrays, or oceanographic instruments.

​Condition Notes (April 2026)

​The unit is palletized and stored indoors.

​Cosmetically, the blue marine coating shows standard offshore wear and light surface oxidation, but the structural frame and drum appear solid.

​The level-wind diamond screw is heavily greased and well-preserved.

​Operational Status: Sold “As-Is” and untested. Requires pairing with a compatible Hydraulic Power Unit (HPU) to verify motor and brake function.
