Resumen de: US2025050978A1
Techniques are disclosed herein for minimizing movement of a fixed marine structure. Using the technologies described, a wind turbine may be mounted on a fixed marine platform (e.g., a fully restrained platform (FRP)) that is secured by mooring lines that may be maintained at a tension to restrain movement of the platform due to environmental loads (e.g., wind, waves, etc.). The mooring lines may be attached to the platform with assemblies that include a stopper attached to the mooring line and engaged with a mooring porch. The stopper may be positioned and/or repositioned to adjust the tension on the connected mooring line and secured in the adjusted position using the various systems and techniques described herein.

The plurality of energy harvesters are positioned on and move adjacent to an upper surface of a body of water, and the locations of the energy harvesters can be monitored and controlled.
