In the increasingly competitive and green-leaning passenger vessel market, maximizing propulsive efficiency is crucial. That’s why our CRP technology is designed for lifelong economy, with reduced energy consumption and emissions. Superb hydrodynamic design with minimal propulsor cavitation enables low noise and vibrations levels, both on board and underwater. CRP propulsors also offer excellent reliability and serviceability, with extended intervals between overhauls.

SP CRP

Innovative design

Unsurpassed efficiency

  • Power range 800–3,500 kW
  • Z-drive and L-drive configuration
  • LM-drive available (integrated vertical permanent magnet (PM) motor)
  • Modern electrical azimuthing
  • Electric motor prime mover or direct diesel drive (with certain limitations)
  • Steerprop technology: dual-end push-pull contra-rotating propellers

Steerprop dual-end CRP offers several benefits:

  • Unsurpassed efficiency due to hydrodynamic qualities of underwater body
  • Low vibration and cavitation
  • Increase fuel savings and lower emissions
  • Low pressure pulses and noise levels
  • Optimized for a wide array of operational profiles without compromising efficiency

Steerprop dual-end CRP evolves CRP technology past the limitations of the pushing-only CRP solution. It combines the outstanding maneuverability of azimuth propulsors with the excellent efficiency of our CRP technology. The design has been tested and verified in action worldwide in over decades.

SP CRP ECO

Innovative evolution

Speed and efficiency

  • Power range 4,500–20,000 kW
  • Z-drive and L-drive configuration
  • LM-drive available (integrated vertical permanent magnet (PM) motor)
  • Modern electrical azimuthing
  • Electric motor prime mover
  • Steerprop technology: push-pull contra-rotating propellers
  • Available with classification in any ice class
  • Modern, pollution-free air shaft seal technology
  • High mechanical efficiency from pressurized lubrication

Steerprop CRP ECO offers several benefits:

  • Unsurpassed efficiency due to hydrodynamic qualities of underwater body – especially at higher speeds of 20 knots
  • Low vibration and cavitation
  • Increase fuel savings and lower emissions
  • Low pressure pulses & noise levels
  • Optimize for a wide array of operational profiles without compromising efficiency

Steerprop CRP ECO combines the advanced hydrodynamic qualities that make our Steerprop CRP propulsors uniquely efficient, with the same fail-safe levels of redundancy that make all our Steerprop ARC propulsors durable and reliable. The end result is a supremely efficient, reliable high-power propulsor for applications requiring high power and high reliability.

The eco-efficient Steerprop CRP ECO product line has been expanded with the new, compact and cost-effective Steerprop CRP ECO LM propulsor with an integrated vertical permanent magnet (PM) motor.

Steerprop CRP ECO LM, with reduced lifetime costs, improved fuel efficiency and low vibration and underwater noise levels, offers benefits to shipowners, builders and designers, and to the environment as well. The compact construction facilitates installation and maintenance, and maximizes onboard comfort.
