Description

The data from the traction winch on the NOAA ship Ronald H. Brown were recorded by the shipboard data acquisition system (SCS).

The traction winch was used off the fantail for the 1-m² MOCNESS and the 10-m²
MOCNESS.

Any questions should be directed to the CMarZ Data Management Office.

Instruments

Traction Winch

Supplied Description:

Instrument Type

Generic Name: Traction Winch

Generic Description:

The traction winch, as it pertains to marine deep water applications, is the primary component of a system designed to provide a significant tractive or load-bearing effort to subsea cable or umbilical. Conventional traction winch systems utilize two sheaves with multiple cable grooves to apply this tractive effort via elliptically reeving cable around the two sheaves. Advancements in sampling instrument packages and vehicles to perform more complex, intervention tasks at greater depths have placed greater demands on the cables and umbilicals linking them to the surface. The traction winch system was designed to address the challenges associated with increased wire or cable tension.
