Marine Power Drives, K-Power Drives

K-Power Drives are designed to provide customers in the marine segment with fully integrated compact, reliable and cost effective drives solutions. Our cabinet built water cooled systems are designed to meet the specific requirements and harsh environment of merchant marine and offshore vessels.

We design and build marine low voltage drives, providing complete electrical engineering, commissioning and service worldwide. Our switchboards are widely adaptable for all types of merchant marine and offshore related vessels, qualified to apply for approval by all major classification societies worldwide.

The K-Power Drive is modularized and easy to configure to any customer requirement. We have prepared a range of pre-configured single drives for AC-hybrid, main propulsion and thruster applications. Based on the same standard modules, the DC CLEAN multidrive offers integrated solutions for hybrid and drilling applications. The K-Power Drive has all essential functions built in as standard to reduce the time for engineering, installation and commissioning.

The control principles have traditionally limited the actual possibilities for an intelligent and dynamic energy control system. By taking control of the whole power production process and introducing new components, Kongsberg Maritime has utilized all information available in the system and used it for creating a fully integrated dynamic energy management system.

The K-Power Drive is an essential part of this new generation energy management and is fully integrated into the KONGSBERG automation environment. Based on standardized control sections, the The K-Power Drive offers full integration of K-Thrust, PMS and EMS systems into the drive lineup. The result is a compact, cost-effective and reliable system with all essential functions co-tested in the factory.

Our drives use internationally recognized name brands of components, which ensures stable quality and simple maintenance during the lifetime of the vessel. Our switchboards are carefully assembled, inspected and tested to ensure customer satisfaction.
