## Description

This project is a technology agnostic high-level study of the costs, risks and opportunities for different cable topology and cable connection methods \(including subsea wet mate connectors\) for offshore floating wind, in comparison to a more conventional topology in a daisy chain configuration between turbines\. This study is important as it aims to answer the following questions: • What topologies will potentially be used for future FOW sites \(e\.g\. daisy chain, fishbone, or star\)? • What type of connectors will be required and their current technology readiness level \(TRL\) in the subsea sector \(i\.e\. what is going to be available in 2025 to 2030\)? • What are the expected failure modes and reliability level of cable array topologies using subsea connectors versus conventional daisy chain arrangements? How does this influence the overall array-level system reliability and redundancy? • What are the installation characteristics of the comparative array topologies for installation and disconnection \(i\.e\. required vessels and equipment, time scales, any additional risks and uncertainties\)? • What are the comparative purchase, installation and O&amp;M costs for different connector and topology combinations?
