Kongsberg Maritime (KM) is celebrating the signing of a brand new contract with the design, improvement, engineering and consulting firm Aker Arctic (Aker Arctic Know-how Inc.) which is able to see KM supplying propellers and shafts for 4 newbuild SQ2020 corvette ships. The method originated in September 2019 when FDFLOGCOM contracted Aker Arctic to design and ship full shaftline system to SQ2020 corvettes and the Rauma Marine Constructions (RMC) yard in Finland to construct the vessels. Kongsberg Maritime’s supply will encompass CPP controllable pitch propellers and shafts for the 4 vessels: every corvette will probably be geared up with two propellers, with the propeller blades, hubs and shafts.

“Kongsberg Maritime’s status for first-rate reliability, effectivity, construct high quality and cost-effectiveness swung the dialogue of their favour when it got here to sourcing CP-propeller programs for the brand new corvettes. We will stay up for the vessels rising from the RMC shipyard in full confidence, figuring out we’ve chosen the very best tools for us to do the job,” says Kari Laukia, Head of Tools Enterprise, Aker Arctic.


“We’re extraordinarily proud to be part of such an necessary undertaking,” provides Niclas Dia, Space Gross sales Supervisor, Kongsberg Maritime. “A lot will probably be demanded of the corvettes all through their operational life, so the belief that has been proven within the high-performing dependability of our CPP programs is an actual accolade.”

KM’s controllable pitch propellers can be found in ice-class, nozzle and open-water variants, with both 4 or 5 blades of excessive skew, average skew, nozzle or standard varieties. With a extremely environment friendly blade foot and blade bearing design calculated to keep away from peak pressures and mitigate publicity to cavitation, KONGSBERG’s Kamewa CP-A propeller system exemplifies the ideas which characterize the complete vary, offering a 20% enchancment within the power-to-weight ratio over its precursor. The brand new controllable pitch hub form cuts down on drag, with sizes to swimsuit energy outputs starting from roughly 500kW to 75MW.
