| Abstract: | Mooring forces of different chain posture are obtained from catenary equations. Relationships of mooring forces and displacements of the attachment point are closed in upon multinomial. The rigid coefficients of the restoring mooring forces are obtained from the relationships. The nonlinear extent of the symmetrically collocated mooring systems is analyzed. The feasibility and the method of the linearization for symmetrically collocated mooring system are studied. The linear matrix of rigidity of the symmetrically collocated mooring system is presented. The method presented in the paper can be used in the dynamic analysis of the floating structures restricted by the symmetrically collocated mooring system. |
