Mooring systems for wave energy converters: A review of design issues and choices
TL;DR: An overview of generic types of wave energy converter (WEC) is presented and their mooring requirements discussed in this paper, where the authors argue that not only station keeping but also the overall performance characteristics of the WEC moorings should be considered in the design.
Journal ArticleDOI
Sensitivity analysis of offshore wind farm operation and maintenance cost and availability
TL;DR: In this paper, an initial qualitative screening sensitivity analysis was conducted to identify the most important factors of O&M affecting operating cost and availability in Offshore Wind Farm (OWF) project lifecycle expenditure.
Journal ArticleDOI
Measurements of static and dynamic mooring line damping and their importance for floating WEC devices
TL;DR: In this article, the design and operation of a chain mooring for a wave energy converter (WEC) is considered, and the experimental results support the conclusion that dynamic moorings line motion will be an important variable, needing to be considered carefully within the design.
Journal ArticleDOI
Review and application of Rainflow residue processing techniques for accurate fatigue damage estimation
Gabriel Marsh,Colin Wignall,Philipp R. Thies,Nigel Barltrop,Nigel Barltrop,Atilla Incecik,Vengatesan Venugopal,Lars Johanning +7 more
TL;DR: In this article, the impact of residue processing on fatigue calculations is demonstrated through the application and comparison of the different techniques in two case studies using long term, high resolution data sets, and an analytical proof of the method presented by Amzallag et al.
Journal ArticleDOI
Mooring design approach for wave energy converters
TL;DR: In this paper, a preliminary design procedure to identify suitable mooring arrangements for floating wave energy converter devices (WECs) is presented. But, since the wave energy industry has little practical long-term experience with deployed WEC systems, there is no historical experience upon which to base the formulation of appropriate station-keeping arrangements.
