Static Calculation of Mooring Systems for Offshore Floating Structures

Abstract

The relevance of the study lies in the importance of ensuring the trouble-free operation of the mooring system of expensive floating structures. Under any external influences, the mooring system must ensure the continuation of the normal operation of the floating object. The purpose of the study is to consider the available approaches and methods for calculating the mooring of floating structures and obtaining the parameters of the system in a static formulation. The methodology used in this study is a combination of methods of complex analysis of complex static systems. It is shown that the static calculation of mooring systems is a simple but at the same time quite effective method. Analysis of the operation parameters of floating structures obtained as a result of the calculation (using the example of the floating project 81260 dock) showed that the complexity of the task of calculating mooring systems depends on the parameters of the structure itself, and at the stage of its operation -on the composition of its mooring system and the efforts arising in it. As a result, it was established that the values of static displacements of anchor chains depend on the angle of inclination of the anchor ties relative to the bottom plane and the values of the acting external loads.
