    Assessment of baseline configurations
    (LiftWEC Project, 2022-08-08) Devoy McAuliffe, Fiona; Horizon 2020
    The purpose of this deliverable is to take a closer look at the potential energy production, installation and OPEX costs for each configuration. The deliverable uses an installation (module of the EU FP7 LEANWIND Financial model) and O&M model (ORE Logistics tool) developed in UCC and further adapted for the LiftWEC project where needed. Programmed in Matlab using Excel input and output files, these operate running Monte Carlo simulations of a scenario against a time series of Metocean data. The models average results, determining the impact of uncertain weather conditions and failure rates on the installation and OPEX costs; installation time; and device power production.

    The IEA Wind Task 49 - Reference floating wind array design basis
    (National Renewable Energy Laboratory, 2024-06) Hall, Matthew; Lozon, Ericka; Devoy McAuliffe, Fiona; Baudino Bessone, Matteo; Bayati, Ilmas; Bowie, Malcolm; Bozonnet, Pauline; Castagné, Michel; Feng, Ju; Housner, Stein; Janocha, Marek; Jiang, Zhiyu; Kim, Yong; Ko, Donghee; Kölle, Konstanze; Lee, Chern; Reddy Lekkala, Malakonda; Liang, Guodong; Mahfouz, Mohammad; Mohan, Madhan; O'Connell, Daniel; Ong, Muk; Prieur, Julien; Rajasree, Vishnu; Schnepf, Anja; Snedker, Thor; Thurston-Keller, Jean; Wright, Chris; Norges Forskningsråd; Sustainable Energy Authority of Ireland; Korean Energy Technology Evaluation and Planning; Ministry of Trade, Industry and Energy; Korea Institute of Energy Technology Evaluation and Planning; Horizon 2020; Equinor; CoreMarine AS; Energistyrelsen; Agence de l'Environnement et de la Maîtrise de l'Energie
    This report provides a general design basis for the development of reference floating wind farm designs. These reference array designs will extend the scope of existing reference floating wind turbine designs to facilitate research on array-level floating wind technology challenges and innovations. The design basis promotes coordination and consistency in developing the reference array designs.

    Model recommendation for optimized commercial scale wave and tidal energy projects
    (Selkie Project, 2023-03-27) Devoy McAuliffe, Fiona; Kamidelivand, Mitra; Interreg Vlaanderen-Nederland; European Regional Development Fund
    This report details the work of D8.5 within WP8 of the SELKIE project. It is linked to the three previous reports of WP8: D8.2, D8.3 and D8.4. The SELKIE project has developed an open access Logistics and O&M tool for tidal and wave energy. A detailed description of the tool as well as methods and model logics are provided in D8.2. In D8.3 and D8.4, the O&M tool was employed to create scenarios of pilot, first array and first commercial scale projects for wave energy case studies based on an oscillating water column wave energy converter (described in D8.3) and for tidal energy case studies based on the Sabella D15 turbine (described in D8.4) in Wales and Ireland. This report provides the description of the sensitivity and scenario analyses of the first commercial scale wave and tidal energy projects studied in D8.3 and D8.4. The report aims to identify key areas in cost reduction and farm availability improvement. It considers different scenarios analyses, for example, the implementation of the weather restrictions for vessel operations, changes in failure rates, adapting a preventive maintenance strategy and the effect of mean time to repair. For each scenario, the impacts on OPEX, availability and energy production are discussed, and the results of optimal wave and tidal commercial case studies in Wales and Ireland are presented.

    Tidal Pilot – Model recommendations for commercial stage
    (Selkie Project, 2023-04) Kamidelivand, Mitra; Devoy McAuliffe, Fiona; Interreg Vlaanderen-Nederland; European Regional Development Fund
    Europe plans to retain its first place as the leader in the ocean energy sector. In the Offshore Renewable Energy (ORE) strategy released in November 2020, the European Commission set a goal of 60GW offshore wind energy capacity and 1GW of ocean (wave and tidal) capacity by 2030. This increases to 300GW and 40GW respectively by 2050 [1]. The ORE target capacity is ambitious, but its implementation remains a challenge. Recent statistics published by Ocean Energy Europe [2] show that cumulative wave energy installation in 2021 reached to 12.7 MW, but only 1.4 MW is currently in the water. The installation capacity of tidal stream energy reached to 30.2 MW, and 11.5 MW is currently in the water. With several tidal stream arrays in operation, tidal energy is approaching widespread deployment [3], however, projects need to reach to operational stage much more quickly.The SELKIE project aims to aid the wave and tidal energy industry in accelerating the deployment and commercialisation of its technology, specifically in the Irish and Welsh regions. The project activity will establish a cross-border network of developers and supply chain companies in Ireland and Wales and create a set of multi-use technology, engineering and operation tools, templates, standards and models for use across this sector. Selkie will test and validate the technology tools on two pilot demonstration technologies, one wave and one tidal. Project resources will be used to undertake meaningful technology transfer of these tools and they will be made open access post-project. This suite of tools includes the SELKIE O&M and Logistics tool, which will allow users to model operations across a project lifecycle to determine energy production and costs as well as running scenarios to optimise the logistics required for the installation and O&M phase.

    Wave Pilot – Model recommendations for commercial stage
    (Selkie Project, 2023-07) Devoy McAuliffe, Fiona; Kamidelivand, Mitra; Interreg Vlaanderen-Nederland; European Regional Development Fund
    This report examines the estimated energy production, installation and OPEX costs for a Wave Energy Converter (WEC) pilot farm based on a generic oscillating water column device. The scenario uses the OE Buoy device matrix. It then looks at a second stage deployment and a full-scale commercial deployment, highlighting advantages of scaling up as well as potential challenges and bottlenecks, ultimately providing recommendations and advice for developers.
