Finland-based Steerprop has launched a CRP ECO LM propulsor featuring permanent magnet (PM) technology from The Switch to offer greater energy efficiency throughout its speed range.
The lightweight propulsor utilises a vertical PM motor, allowing it to sit inside a vessel hull. The motor is placed on top of the thruster, which aims to make the unit compact and increase efficiency without compromising on hydrodynamics.
Mika Koli, business development manager at The Switch, said: “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.
“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.”
The third generation CRP is constructed to suit easy installation and maintenance and low operational costs.
Designed for operation in harsh environments, it can cope with the demands of ice breaking. Other Steerprop propulsors have previously been used to power wind turbines in rough offshore conditions.
Hannu Jukola, senior sales manager at Finland-headquartered Steerprop, stressed: “This is a best in class solution that fully capitalizes on the potential of two energy-efficient innovations, in one simple, effective and powerful propulsion unit.”
