Geometric analysis of pontoon and mooring line towards hydrodynamic response

Abstract

Floating Photovoltaics (FPV) are renewable energy producing technological breaktroughs whic are suitable to circumtances of lakes across Indonesia. The core of this technology is the function of working transformers installed on the pontoons. An FPV with 145 Mwac capacity is designed to run on Cirata weir by utilizing pontoons with the length of 16.5 meters. The hydrodynamic response in the form of plane and rotation movements due to surrounding loads (including but not limited to wave, wind and sea depth data) calculated by using Response Amplitude Operator (RAO) concept. The wave period measured in meter from 0 to 180 ° incoming degree, the biggest translational response comes from pontoon i.e 0.986 (m/m) in sway direction, spread mooring is used to limit the pontoon’s movement. Using weighing concept, in operating condition Tension Mooring Line is obtained at the value of 1.67 for pontoon. While in extreme condition the obtained value is 2.5.
