Single Point Mooring (SPM) are floating Structures that are deployed in deep water which their duties are vessel mooring and transferring oil and gas productions by pipelines from shore to petroleum tankers and conversely. One of the most important components of SPM is mooring system. Which bears not only environmental loads but also petroleum tanker loads which conducted by two thick ropes. Mooring system of SPM regarding the important responsibility it has, has been pay attention to a lot. Proper mooring system leads to efficiency improvement in different environmental conditions and mooring system life increase.
In this research SPM with four mooring lines are simulated by ANSYS AQWA Software and forces on the SPM calculated diffraction theorem and Boundary Element and mooring lines are calculated by Morrison theorem.
