Passive mooring system enables floating PV to track water-level changes Researchers have developed a passive counterweight-and-pulley mooring system for floating PV that automatically tracks water-level changes while significantly improving platform stability. Laboratory-scale testing and numerical simulations showed reductions in surge and sway motions of up to 71.7% and 65.6%, respectively, while achieving a 75% water-level tracking efficiency.
