Overview

A group of landscaping studies were carried out concurrently to help WES identify a number of research challenges that could be addressed in future funded projects. This study, along with one looking at Electrical Connections, helped to inform the Quick Connection Systems call in 2019.

This mooring and foundations landscaping study demonstrates that there are clear opportunities to make an impact on the cost of energy of wave power through further development and innovation in mooring components, foundations and associated subsystems. The study has been conducted in four main work packages which include:

  • State-of-the-Art desk study review of the current mooring and foundation landscape 
  • Voice of the Customer survey 
  • Moorings & Foundations Innovation through a TRIZ workshop
  • Mooring & Foundation Case Studies

The combined output of these work packages was then used to identify R&D opportunities which could have a positive impact on the cost of energy.

Project partners were University of Exeter and Black & Veatch.

Cost Reduction in Supporting Infrastructure - Moorings and Foundations

December 2018

A range of device scales, water depths and mooring footprint radii were studied which were compatible with the range of device scales and sites identified by the Voice of the Customer survey. It was not possible to consider every class of mooring system via the case study assessment, however, the VOC survey confirmed that spread type mooring systems, whether chain catenary or semi-taut synthetic-based systems are a popular choice within the sector. The four-strand approach also helped identify gaps in sector know-how while identifying contradictions for instance, sector requirements and technical viability and affordability.
