Abstract

This theme was selected from many ideas talked at the free discussion and taken by the questionnaire for the purpose of finding the possibility of new shafting system.
In this paper, possibility of realization and effectiveness were checked by trial design and alignment calculation. And also, problems derived from aft support of propeller and measures for utilizing the merit were investigated.
On the trial design, 230 type tanker was taken up as the sample and the shafting system was so designed that the current parts of shafting were used without any modifications as far as possible. And the realization was finally confirmed.
From the results of alignment calculation on the trial design, it was confirmed that the bending moment of propeller shaft at supporting position of stern tube aft bearing as well as the bearing load intensity were in low level.
