Fast and Safe Operation. Voith Radial Propeller

Semisubmersible platform with Voith Radial Propellers. Voith Radial Propeller (VRP) for the Offshore Industry. The Voith Radial Propeller (VRP) is a 360° thruster specially designed for the requirements of large offshore vessels as semisubmersibles or monohull drill-ships. Special features include underwater-mounting, pressurized l ­ubrication system and bearings for DP requirements. Retraction systems are optionally available. Hydrodynamically the 8°-axis tilt by special gear t ­ echnology ensures more useful thrust by losses avoided due to interaction effects. Patented high lift nozzles...

2 Underwater-mounted VRP 3 lingelnberg gear-cutting machine. K Voith has decades of experience in designing and producing marine propulsion systems, such as propellers for commercial and military vessels. Examples are offshore supply vessels, tugs and ferries, which operate with Voith Schneider Propellers (VSP). Other typical marine products are shaftline components for ice going vessels. The first semisubmersible vessel was fitted with Voith Radial Propellers (VRP) in 1975. Voith can look back on decades of in-house operating and maintenance experience for thrusters. Voith Radial Propeller...

5 4 EM analysis for VRP. F 5 CFD analysis for thruster below U ­semisubmersible vessel. Capacity For producing very large water turbines Voith has various workshops for welding, casting, forging and machining. K ­ aplan turbines (similar to CPP) with diameters significantly above that of the thrusters are regularly produced. The backbone of the Voith thruster production is our own manufacturing capacity. All core components are produced in-house without the involvement of sub-suppliers. Voith operates one of the world’s largest Klingelnberg gearcutting machines in Heidenheim, Germany....
