Title:
METHOD FOR REDUCING HULL PRESSURE FLUCTUATIONS BY CONTROLLING ANGLES OF ROTATION OF PROPELLERS OF TWIN-SCREW VESSEL
Document Type and Number:
WIPO Patent Application WO/2018/117355
Kind Code:
A1
Abstract:
The present invention relates to a method for reducing the overall pressure fluctuations by controlling the phase difference of pressure fluctuation time series of the two propellers of a twin-screw vessel, wherein with respect to controlling the phase difference of the pressure fluctuation time series, the optimal relative angles of rotation of the two propellers are calculated, and the results are then stored and referenced to maintain the rotational state of the propellers at the optimal state. The present invention can effectively and in real-time reduce, in accordance with sailing conditions of the vessel, pressure fluctuations induced on the hull surface due to propeller cavitation.
