Dynamic Positioning Drive
Since the development of satellite navigation, it is possible to keep drilling platforms and ships in position dynamically using their own drive units. The steering propeller units driven by electric motor are most often designed as vertical drives, meaning the electric motor, as well as the shaft line (telescopic shaft) are mounted in a vertical position. The flexible coupling required to tune the drive line in terms of torsional vibration (propeller excitation) must, in addition, also ensure the radial and axial guiding of the drive train.
The VULKAN RATO DG meets these requirements perfectly. In terms of construction, no significant modifications of the standard design are necessary, which makes this solution commercially very attractive.
