Deliverable 3.2b Design Basis and Technology Gap Analysis Report is live on DTU Data
Deliverable 3.2b Design Basis and Technology Gap Analysis Report is now available on DTU Data: ESOMOOR project.
This report presents the design basis and identifies knowledge gaps related to shared mooring systems for FOWFs.
The design basis serves as a guiding framework outlining the approach, methods, and criteria for designing floating platforms and their mooring systems. It primarily covers:
- Standards, rules, and regulations
- Definition of coordinate systems
- Baseline floaters and mooring configurations
- Site and metocean conditions
- Design and analysis requirements, including safely philosophy, design life, and the partial safety factor method
- Limit states, such as Accidental Limit States (ALS), Fatigue Limit States (FLS), and Ultimate Limit States (ULS), and the corresponding load factors
- Floating stability.
The scope of this report is limited to the mooring system, while standardized and validated data are used for components above the free surface, such as wind turbine blades, towers, and nacelles.
Identified technology gaps in the shared mooring system include:
- Use of nonlinear materials in mooring ropes instead of the traditional steel chain
- System redundancy of a shared mooring system
- System dynamics of a shared mooring system
- Integration of the cable design and the overall mooring system
- High computational demands
- Limited availability of validation data
- Occurrence and modeling of snap loads.
