Abstract

The problem that might occur in floating structures with mooring systems is clashing between mooring lines with subsea equipment, for example pipelines. Addition of subsea buoys on the mooring line can lift the mooring line so that it can avoid clashing. The addition of the subsea buoy can affect tension on the mooring line. This research discusses the effects of subsea buoy to the tension of mooring line with a variation position of subsea buoy. Variations on the position of one subsea buoy is arranged at the distance of 605 m, 577.5 m, 550 m, 522.5 m from anchor and two subsea buoys at the distance 605 m and 467.5 m from the anchor. The analysis was carried out on stand alone and offloading conditions with wave directions 0,̊ 45,̊ 90,̊ 135,̊ 180.̊ The results after the addition of subsea buoys it has a smaller tension on the mooring line. The result of the variation of subsea buoy position, the optimum position to get the smallest tension value is when the variation of two subsea buoys with a distance of 605 m and 467.5 m from the anchor. From the results of the analysis there is also no clashing between the mooring line and pipeline.
