Abstract
Following the successful installation of the world’s first GATE RUDDER® system on a 400 TEU container ship (see Figure 1), superior fuel saving and manoeuvring performances have been recorded with this vessel over her sister ship fitted with a conventional rudder. Also, noticeable reductions in the aft end vibrations and noise have been reported by the captains and crew of these vessels in service. This paper describes and discusses the results on the recent Cavitation tunnel tests conducted in the Emerson Cavitation Tunnel with the same geometry of the full-scale rudders and propellers for the above-mentioned vessels except for the same wake distribution due to the current limitation of the test facility used. The results presented in the paper may help to shed a light on the full-scale Cavitation and noise performances of the two sister ships currently operating between the North and South of Japan by following the same route.
