Steerprop CRP and CRP ECO

Steerprop contra-rotating propellers (CRP) in a push-pull configuration are specifically designed to meet the toughest customer needs. We combine the outstanding manoeuvrability of azimuth propulsors with the excellent efficiency of our CRP technology.

CRP technology allows vessels to operate under demanding conditions where high fuel efficiency is a critical factor. The design has been tested and verified in action worldwide for decades.

Steerprop CRP and CRP ECO Propulsion Units


  • Dual-end push-pull contra-rotating propellers
  • Power range for CRP from 900 to 3,500 kW and for CRP ECO from 5,000 to 15,000 kW
  • Z-drive or integrated permanent magnet motor drive
  • Applications: vessels with demand for high comfort class, good fuel economy with or without ice
    class and icebreakers
  • SP CRP is ideal for ferries, offshore vessels and merchant vessels
  • SP CRP ECO is also ideal for cruise vessels, as well as icebreakers and high ice class vessels

Main benefits

  • High manoeuvrability
  • Light load on propellers, resulting in:
    • Good cavitation performance
    • Low noise and vibration levels
    • High efficiency
  • Low emissions due to good fuel economy
  • Higher bollard pull / DP-thrust compared to single open propeller
  • Effective ice milling with pulling propeller
  • Best ice management with propeller wash
