Recent work shows how an advanced mooring optimisation approach can explore complex designs and deliver cost-efficient solutions while meeting key structural and operational requirements.

Our WindCrete Spar concept was used in this study as a case application; the results highlight that the mooring system cost is strongly driven by line orientation, pretension levels, and the number of load-bearing lines. In Spar platforms, CAPEX is dominated by upwind and sidewind lines, with yaw and heave control requiring specialised mooring layouts and robust bottom components.

In this study, anchors and bottom chains are the main cost drivers, and combining frequency and time-domain analyses is essential, especially for yaw and fatigue in Spar platforms.

These findings position WindCrete as a robust and optimal solution for deep-water floating wind, supporting informed design decisions and cost-efficient project development.
