121537 - Design Analysis of Shared Mooring for Floating Offshore Wind Farm 

The development of wind energy in deeper waters offers advantages, but floating offshore wind turbine (FOWT) faces challenges due to their higher levelized cost of energy (LCOE) compared to onshore and fixed offshore turbines. An intriguing concept, the shared mooring system, aims to reduce costs but has not been practically applied or validated in real-world engineering projects. As a result, the design methodology, specialized analytical tools, and industrial rules for the design and analysis of shared mooring remain unavailable. The entire shared mooring system consists of several FOWTs, anchor lines, shared lines, and other mooring ancillaries, forming a highly intricate multibody system with uncertain structural topology, nonlinear dynamics, and unknown failure mode. Authors are going to summarize the latest research works related to construction of methodology for design analysis of shared mooring system. Details related to different levels of dynamic models are presented including the spring-mass model, quasi-dynamic model, fully coupled sub-model. A dedicated module for shared mooring analysis is developed within the in-house software KraKen. The design constraints and considerations, modal characteristics, global performance, transient effect due to sudden line loss, adaptability of various mooring line models, structural redundancy of the entire system are discussed based on numerical simulations and survey of present rules.
