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.
