US 2025/0050978 A1 · MOORING SYSTEMS FOR FIXED MARINE STRUCTURES

Abstract

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.

Dependent claims

A system, comprising:

a fixed marine platform to host a wind turbine;
a mooring porch coupled to the fixed marine platform;
a stopper configured to engage with the mooring porch;
an anchor attached to a seafloor;
a mooring line comprising a first end coupled to the anchor and a second end coupled to the stopper and extending through the mooring porch;
a hydraulic power unit;
one or more hydraulic cylinders connected to the hydraulic power unit and configured between the stopper and the mooring porch, wherein the one or more hydraulic cylinders are configured to expand under control of the hydraulic power unit to increase a distance between the stopper and the mooring porch;
and
one or more stopper retention components configured to secure the stopper in a position relative to the mooring porch.
