scope:

This document specifies requirements for the design, construction, safety, performance and acceptance testing of dual traction/stowage winches for oceanographic research (hereafter referred as to "dual traction / stowage winches"), with hydraulic and electric drive. Dual traction/stowage winches are mainly used for fixed-point and towing marine survey, involving marine geological sampling, seawater water body parameter measurement and marine biological survey. This document is applicable to the design, manufacturing, and acceptance testing of dual traction/ stowage winch.
