Abstract

Wave Energy Converters (WECs) is the type of Ocean energy need continual motion while operation for producing steady electricity. The mooring configuration as the answer for making sustainable WECs during operational life on the rough sea. The authors are researching trimaran pontoon of pendulum WECs type with anchors and four cables of mooring. The purpose of this research to determine the heave, pitch, and roll response from the pontoon. In this research, there are variations of wave height and wave periods. Experiment located at hydraulics laboratory in regular wave condition. The scale-up of the pontoon is (1: 10) compared to real dimension. IMU (Inertial Measurement Unit) sensor used in this experiment to detect pontoon motion. Pontoon has the optimum condition at wave periods at 0.6 s and height 0.4 m. Heave motion best displacement is 0.372 m, Roll motion value is 1.425 degree and Pitch is …
