Our innovative TFI Marine SeaSpring technology is proving to be a game-changer for mooring systems in Floating Offshore Wind Turbine (FOWT) applications. Extensive case studies demonstrate the significant advantages of SeaSpring across various floating platform types and mooring systems.
Key Findings from Our Comprehensive Analysis:
- Significant Load Reduction: SeaSpring effectively reduces peak mooring loads by 50% or more, depending on the platform type and mooring system.
- Enabling Taut Mooring Systems: SeaSpring facilitates the use of taut mooring systems in shallow to mid-range water depths.
- Smaller Footprint Design: Implementing SeaSpring allows for mooring designs with a smaller environmental footprint.
- Improved Line Dynamics: While the primary focus is on ultimate strength, SeaSpring also stabilizes line dynamics, reducing erratic movements and improving fatigue behavior. Future studies will further explore these fatigue benefits.
Case Studies at Utsira Nord, Norway:
Our Whitepaper presents five initial case studies, analyzing various combinations of mooring systems and floating platform types at the Utsira Nord site offshore Norway. Each study includes a base case mooring configuration and an alternative configuration utilizing SeaSpring components.
Methodology and Guidelines:
- Dynamic Analysis Procedures: The correct SeaSpring parameters are identified through comprehensive dynamic analysis using fully verified tools. Our outlined procedures serve as a guideline for incorporating SeaSpring into mooring designs.
- Design Load Cases: Analyses are based on Ultimate Limit State (ULS) design load cases and the MetOcean design basis for the operational location.
