10-vessel order for Voith ‘intelligent’ propellers

Each of the 10 vessels will be fitted with two propellers.

The Contur F is described as “a ship’s propeller that can adjust its pitch without mechanical components”. The principle behind the so-called ‘intelligent’ propeller lies in its material structure and its design. The propeller consists of a metal hub, with blades made from flexible yet strong carbon fibre compounds. The Contur propeller is produced in diameters up to 3m, with a power hadling capability of up to 3,500 bhp, which Voith says makes it particularly suited to large yachts, passenger ships, military applications and authority vessels.

A claimed 35% weight saving is further backed up by quieter running, low vibrations, improved acceleration properties 10 % higher maximum speeds. Voith says that fuel savings of about 15 % are possible with the Contur F propeller. Furthermore, because the blades are individually made, damaged blades are easy to replace, lowering maintenance and service costs. The propeller blades can be supplied ex works with a growth-repellent surface coating to further reduce maintenance.
