Draftec is specialized in the design and construction of customer-specified high-end winches, designed for easy vessel integration.

Draftec has supplied winches for a wide range of applications with safety devices for overload protection such as AOPS or MOPs in combination with passive heave compensation or active heave compensation (AHC), constant voltage (CT) and manriding functionality.

The specifications of offshore winches are the following:

  • Safe working load 1 to 100 mT
  • Holding force up to 200 mT
  • Nominal speedup to 100 m/min
  • Control functions:
    • Active heave control
    • Constant tension
    • Load limitation (rendering)
    • Overload protection systems (MOPS & AOPS)
    • Manriding
    • According to Class (e,g, DNV, BV)

The design of a high-end winch of Draftec is compact and modular. The components are standardized and exchangeable. The power requirements are optimized and the limited deck space is required. Moreover, the offshore winch is electric or hydraulic driven and the control with an integrated control system.
