Azimuth propulsion specialist Steerprop has unveiled its new CRP ECO LM propulsor featuring permanent magnet (PM) technology from The Switch.
The new Steerprop CRP ECO LM propulsor utilizes a vertical PM motor, allowing it to sit inside a vessel hull, which simplifies installatio[ds_preview]n and maintenance. When the motor is placed on top of the thruster, the unit size can be more compact, increasing efficiency without compromising on hydrodynamics and lowering operational costs. The PM machine, currently in serial production, has a solid track record of operating in the world’s largest wind turbines in rough offshore conditions.
»Steerprop’s contra-rotating propeller (CRP) units are well known for their excellent hydrodynamic efficiency, in some cases delivering up to 25% less fuel consumption than single propeller, traditional electric alternatives,« comments Mika Koli, Business Development Manager, The Switch. »By combining their unit with our PM motor, which gives optimal efficiency throughout the entire speed range, we can take vessel energy, emissions and cost savings to the next level.«
Steerprop’s CRP ECO LM propulsor is said to be especially suited to harsh environment operation and the demands of ice breaking, having received the highest ice classification. It is robust and, thanks to its lightly loaded CRPs, offers lower noise and vibrations, enhancing levels of comfort onboard.
The Switch entered the marine segment in 2013, acquiring Wärtsilä Drives in Norway in November last year. The ambitious business, part of the 3.3 bn € turnover Yaskawa Electric Corporation, is now targeting growth of 200% in the sector across the course of the next five years.
