The Steerprop retractable azimuth thrusters set the benchmark for Dynamic Position (DP) performance.
Why Steerprop Retractable Thrusters?
Steerprop’s retractable thrusters go beyond industry standards to deliver energy-efficient, reliable propulsion engineered to strict performance and quality criteria. Designed for easy operation and simplified maintenance, they enhance dynamic positioning (DP) capability and overall vessel performance.
Because sealing and locking mechanisms are often weak points in retractable designs, the retractable thruster series is engineered to minimize downtime, maintenance demands and onboard space requirements while maintaining high-performance propulsion and DP capability. A patent-pending seal design actively manages water ingress and enables low-maintenance servicing from inside the vessel during operation, while a floating housing maintains seal performance in demanding conditions and reduces marine growth.
A hydraulic locking and lifting mechanism further improves reliability while addressing deck space constraints. The compact, zero-clearance design fits below the main deck on most vessel types and supports flexible propeller sizing up to 3.2 m to match vessel requirements.

Steerprop Retractable Thrusters
Designed to maximize uptime and reduce maintenance, the fixed pitch propulsion system fits seamlessly into vessels requiring station keeping or dynamic positioning. Precise electric steering and a tilted lower gear design improve efficiency, reliability and integration in demanding conditions. Propeller diameter can be adjusted based on performance requirements and available space.
Steerprop’s patent-pending seal design actively manages water ingress and enables low-maintenance servicing from inside the vessel, addressing common industry challenges with sealing and locking mechanisms. A floating housing maintains seal contact in all conditions, while a scraping solution reduces marine growth and helps prevent seal damage, further improving reliability.
The Steerprop Retractable Thruter series is available in L-drive, permanent magnet, or induction motor configurations to suit a wide range of vessel power arrangements. Electric steering gear delivers the precision required for dynamic positioning, while power output and propeller sizing can be tailored to each application, across a range of 850 to 3,500 kW.
Every Steerprop Retractable thruster unit includes Steerprop Care condition monitoring as standard. Fully integrated into the propulsion system, it enables crews to monitor machinery trends and identify potential issues early, ensuring reliable performance and helping avoid unnecessary costs and dry docking.
Technical drawings of Steerprop propulsion systems, including weights and dimensions, are available in the Drawing Database to support efficient concept design.
