    Abstract

    This paper shows the results of an analytical calculation of newly designed hydrostatic bearing with pressurized oil supplied through the inner shaft, and that they are in good agreement with the experimental results in terms of oil film thickness, moment support capability and oil flow rate. This paper also presents the results of tests on a full-sized contra-rotating shafting and bearing simulator tester of 60 000 GT bulk carrier ship. Asynchronous contra-rotation was proven to assist CR bearing operation in partly fluid film lubrication region and to prevent severe seizure of it.
