GEAR | Kongsberg Maritime to supply propeller systems for five Spanish Navy frigates

Kongsberg Maritime has secured a contract worth NOK200 million (US$22.17 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 earlier F100 frigate and will be used in anti-submarine warfare (ASW) operations.

Each vessel will be fitted with twin Kongsberg Kamewa controllable-pitch propeller (CPP) systems, specifically developed for minimum noise and vibration throughout the system from the propeller blades through the shaftline to associated equipment such as the bearings and hydraulic power unit.

Navantia had selected the Kongsberg CPP systems after scale model tests showed that these delivered acceptable levels of underwater radiated noise (URN), cavitation inception speed (CIS), pressure pulses, and efficiency. All these factors are considered essential in surface ships engaged in ASW missions.
