Abstract
In this article, the role of moorings in the heave and pitch movements of the semi-submersible platform is investigated due to the increasing use of these platforms in deep waters. Improper movements of the platforms can cause instability of the structure and disrupt its performance. In order to analyze the movements of the platform, taking into account the role of moorings, the numerical simulation of Amir-kabir platform with different mooring modes has been performed as a nonlinear analysis in the time domain using Orca-flex software. By examining 52 different mooring compound models in three stages, 5 mooring compound models have been introduced in terms of the motion response of the semi-submersible platform in the heave and pitch. The results show that the independent combination of catenary and tensile moorings, in addition to the overall reduction of the length of the moorings, causes optimal behavior in the heave and pitch movements of the semi-submersible platform.
