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 dynamicrnpositioning system propellers of the semi-submersible platform.rnAccording to the relevant standards, provided by the register ofrnshipping, which have set the maximum allowable tilt angle of a semisubmersiblernplatform, a research is taken about the effect on dynamicrnpositioning system under a series of heeling and trimming angles byrnstudying the changes of thruster-thruster interaction patterns. Afterrnnumerical simulations, the time-domain curves of positioning accuracyrnand power consumption can come out. 1Finally, an analysis is madernabout the reasons of the results, besides; some applicable conclusionsrncan be carried out.
