Abstract
In the 1st and 2nd reports, it was shown that a newly developed hydrostatic bearing with pressurized oil supplied through an inner shaft is suitable as a stern bearing for a contra-rotating propeller system. This paper presents a theoretical analysis of coupled shaft alignment and bearing performance for a CRP system, taking account of propeller forces, and measurement results of bearing performance of a full-scale ship, which is the world's first merchant ship to be equipped with contra-rotating propellers. It is confirmed that measured results of oil film thickness and inclination angle between inner shaft and stern bearing agree well with predicted ones.
