A Research of the Effect of Heeling and Trimming on a Specific Semi-Submersible Platform with Dynamic Positioning System

摘要

This paper starts from the hydrodynamic performance of dynamic positioning system propellers of the semi-submersible platform. According to the relevant standards, provided by the register of shipping, which have set the maximum allowable tilt angle of a semisubmersible platform, a research is taken about the effect on dynamic positioning system under a series of heeling and trimming angles by studying the changes of thruster-thruster interaction patterns. After numerical simulations, the time-domain curves of positioning accuracy and power consumption can come out. 1Finally, an analysis is made about the reasons of the results, besides; some applicable conclusions can be carried out.
