STABILITY ANALYSIS FOR TRIMARAN PONTOON ARRAY IN WAVE ENERGY CONVERTER – PENDULUM SYSTEM (WEC - PS)

Ocean waves are a renewable energy source with abundant reserves in Indonesia. With the vast waters of Indonesia, development sea wave power plant needs to be developed. This research focuses on easy-operated and maintained ocean converter–pendulum system (OWC – PS). The numerical simulation experimental analysis were conducted obtain relation between motion response pontoon array its pendulum. used is trimaran type, which consists cylindrical as main hull two outriggers side. study analyses most stable arrangement that produces maximum pitching pendulum deviation. results show largest value 1, i.e., 27.91° for 1 38.92° 2, deviation 100 ° pendulums 56.2 2 over period 9 seconds. backward both configurations tends have greater than forward motion. different characteristics, represented by values pendulums. phenomenon does not occur since same (with only small discrepancy).
