Electric Propulsion System
Green & Smart Ships
Electric Propulsion System
It is a system that supplies the main power source of a ship by operating electricity and batteries alone or in parallel.
It consists of Power Management System (PMS) that controls the power generated by the generator, Energy Management System (EMS) to monitor and control the generated power, a power inverter for hotel loads that supplies power to loads in ships, an inverter driver that supplies power to the propulsion motor and compact, high-performance Rim Driven thruster.
Currently, KTE is carrying out the 'development of electric propulsion driveways and mobile power supply system' and 'commercialization of LPG electric propulsion system for small and medium-sized ships'. Through these projects, we are conducting R&D to secure an 'Electric Propulsion System Package' solution that includes all thrusters in the future.
