In Indonesia, one of the regions that have good potential for Floating Offshore Wind Turbine (FOWT) installations is the Natuna Sea which has a fairly good average wind speed in the range of 10.0 - 15.0 m/s. In addition, the Natuna Sea has a water depth of around 50-250 m with relatively mild wave height. This condition is a suitable environment for the installation of the FOWT. Therefore, it is necessary to investigate the appropriate mooring system configuration due to the motion of the structure. This paper examined the analysis of mooring system of the SPAR type FOWT structure due to its global motion through numerical modelling by using open source software FAST. The analysis was carried out for operation condition, by varying three configurations of the mooring system for the direction of environmental loads (waves and winds), namely 0 degrees (perpendicular in front of the turbine), 45 degrees, and 90 degrees (the turbine side direction) and wind speed. With the scope of such analysis, it could be properly examined the mooring system due to the global motion of heave, roll and pitch of the Spar.
