Kongsberg Maritime Propeller Systems for 5 Spanish Naval Frigates
Kongsberg Maritime has secured a contract worth NOK 200 million with Spanish shipbuilder Navantia to supply propeller systems for five F110 frigates, currently in construction for the Spanish Navy. These next-generation vessels are designed to follow on from Navantia’s successful F100 frigate, bringing together state-of-the-art technologies to create a ship for the 21st century.
Destined for Anti-Submarine Warfare operations, each vessel will be fitted with twin Kongsberg Kamewa Controllable Pitch Propeller systems, specifically developed for minimum noise and vibration throughout the system; from the propeller blades through the shaft-line to associated equipment such as the bearings and hydraulic power unit. Vessels engaged in ASW must meet exacting requirements on Underwater Radiated Noise, Cavitation Inception Speed, pressure pulses and efficiency in order to operate effectively, and Navantia’s selection process for the propellers for the F110 frigates included model scale tests at Marin in the Netherlands and at CEHIPAR in Spain to verify that the performance targets were met.
