Vaasa, Finland-based Danfoss<\/a> Drives is supplying variable-speed AC drives for the propulsion systems of the Finnish Navy\u2019s four Pohjanmaa-class multi-role corvettes. Part of the Finnish Defense Squadron 2020 project, these corvettes are under construction at Rauma Marine Constructions\u2019 (RMC) shipyard in Rauma, Finland. These AC drives are engineered to withstand the demanding naval environment and comply with stringent requirements for environmental resilience, shock resistance, electromagnetic compatibility, and national Navy\/NATO standards.\u00a0<\/p>\n

The multi-role corvette is a warship capable of effectively executing the Navy\u2019s missions at sea year-round. In terms of performance and features, these warships are designed for the varying conditions of the Baltic Sea and international operations. The Squadron 2020 project vessels are scheduled for completion by 2029.<\/p>\n

\u201cDelivering our megawatt-class, liquid-cooled AC drives from the Danfoss iC7 product series for Finland\u2019s new Squadron 2020 corvettes is a milestone for Danfoss Drives. These drives are engineered to meet the demanding needs of the marine industry,\u201d says Mika Kulju, President, Danfoss Drives.\u00a0<\/p>\n

\u201cThis project highlights the strong collaboration with our local partners WE Tech and VEO in Vaasa, Finland, as well as RENK in Germany, who facilitate delivery to the Rauma shipyard. We deeply value the trust placed in us by the Finnish Defense Forces and RMC’s Rauma shipyard,\u201d says Mika Kulju.<\/p>\n

Demonstrating their versatility, Danfoss\u2019 megawatt-class, liquid-cooled AC drives \u2013 identical to those being supplied to the Finnish Navy \u2013 are also deployed on Wasaline\u2019s Aurora Botnia ferry on the Vaasa-Ume\u00e5 route. For the past four years, the Aurora Botnia has utilized Danfoss AC drives to orchestrate a sophisticated hybrid propulsion system, seamlessly managing power distribution from the LNG main engine\u2019s generators to 2×6-megawatt propeller motors and a 2-megawatt-hour battery bank. This system, controlling a total of 35 megawatts, underscores Danfoss\u2019 expertise in advanced power management. The Aurora Botnia was also built at RMC\u2019s Rauma shipyard.<\/p>\n

\u201cThe fact that we have a versatile shipyard capable of meeting the Navy\u2019s demanding requirements reflects the strength of Finland\u2019s shipbuilding expertise, and one that places its trust in the reliability and performance of Finnish technology, especially the advanced drive solutions from Danfoss Drives, whenever possible,\u201d says Mika Kulju.<\/p>\n

What is a frequency converter?
\nA frequency converter controls an electric motor by varying the frequency and voltage of the power supply. This is often referred to as speed control, as it adjusts the motor\u2019s speed.<\/p>\n
