Cavitation tunnel testing

The KHRC test facility


  • For over 80 years Kongsberg Maritime has developed world class products and capabilities for marine propulsion in Kristinehamn. Here propellers, thrusters and waterjets have been developed for some of the world’s largest and most prestigious vessels. Millions of cubic meters of fuel have been saved in the form of more efficient propulsion systems.
  • Unlike other propulsor suppliers, Kongsberg Maritime has its own marine propulsion laboratory in Kristinehamn, Sweden, equipped with two cavitation tunnels, one free-surface and one conventional tunnel.
  • Since the first propeller laboratory opened in 1942, about 1.600 models of propellers and waterjet pumps have been tested.

History of KHRC

The new marine laboratory, opened in 1971, is today called Kongsberg Hydrodynamic Research Centre (KHRC) and serves as a hydrodynamic centre of excellence supporting any customer or business unit across Kongsberg Maritime.
