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.International Energy Agency Wind Technology Collaboration Programme (IEA Wind) Task 49 on Integrated Design of Floating Wind Arrays is an international collaboration aiming to advance the development of large-scale floating wind farms by providing open-access resources to the research and development and planning communities. The work of Task 49 focuses on array-level challenges related to the colocation of many floating wind turbines; their layouts, mooring systems, and cabling systems; failure risks; logistical considerations; marine spatial planning needs; and future research needs and innovation directions. Task 49 is a 4-year effort that began in December 2021 and that includes representatives from project developers, technology providers, universities, consultancies, regulatory agencies, and research institutions from 12 countries. Its four work packages (WPs) have the following objectives:• WP1: Curate a set of site conditions representative of the global floating wind pipeline • WP2: Develop reference array designs for typical site conditions and technology types • WP3: Catalogue array-level failure risks, consequences, and mitigation strategies • WP4: Identify critical innovation opportunities and marine spatial planning requirements. This design basis report is the first major output from WP2, and it presents the approach for developing reference floating wind array designs. The contents of this design basis were developed from extensive discussions among WP2 participants, including five working groups focused on different areas during the first phase, and a group of three design teams that identified more specific challenges and approaches during the start of the design phase.Floating wind farm design involves many additional factors relative to individual floating wind turbines or fixed-bottom wind farms. Further, reference designs have different requirements than real projects. Therefore, this design basis contains important information and decisions to give definition to the reference floating wind array design effort. Reference Array Design ScopeThe main purpose of the reference designs is to support floating wind research and development at the array scale by serving as ready-made inputs for testing analysis methods, standardized designs upon which different innovations can be developed and evaluated, and baselines that different design variations can be compared against.The scope of the design effort was converged upon after extensive input and discussion. The reference designs will use existing reference floating wind turbine/platform designs and will focus on developing mooring systems, cabling, and array...

“…In the DTOcean+ project [8], open-source design tools were developed for selection, development and deployment of ocean energy systems, including offshore wind. The methods implemented contain a simplified procedure for optimising the infrastructure solutions where the costs of all options are calculated and the one found to be the most promising is selected [9].…”

For offshore wind farms, a move from a preventive and corrective maintenance regime to a predictive maintenance regime requires new methods for modelling approaches for maritime logistics planning. This paper presents an overview of the maritime logistics planning problem for a predictive maintenance regime and introduces the current state-of-the-art for operational research in the field of operation and maintenance at offshore wind farms. Findings are that a combination of the vessel resource scheduling problem for operation and maintenance at offshore wind farms with predictive analysis and digital twins is a promising future research step. A framework for a decision support tool is presented that will help bridge the gap, both with respect to the academic path, and the gap between academic research and industry.

“…Wave and tidal energy have low variability compared to wind, can be accurately forecast, and thus can be complementary to wind and solar energy, smoothing the otherwise peaking nature of renewables in the production mix [6], [7]. However, the ocean energy sector is still facing challenges related to performance, reliability, and survivability which ultimately translate into above gridparity costs [8]. Also, many of the animal populations that reside in the energy-rich areas of the ocean are already under considerable stress from other human activities including shipping, fishing, waste disposal, and shoreline development [9].…”

“…The collision risk relates to the moving components of devices (blades and rotors), as well as vessel traffic from and to deployed ocean energy sites. One way of helping the ocean energy sector to move forward is to develop forecasting tools that support developers in designing reliable ocean energy arrays with reduced costs ( [8], [10]) and tools to (i) predict the arrays' potential environmental impacts and (ii) prove their efficiency in reducing greenhouse gas emission.…”

Designing reliable ocean energy devices with reduced costs is crucial for the sector’s development. This development of renewable energies should also be implemented in a sustainable manner and not cause additional environmental stress and related damage. In order for the ocean energy sector to consider environmental impacts at the earliest stage of concept creation, the Environmental and Social Acceptance (ESA) module was developed and included in an integrative suite of design and assessment tools (namely DTOceanPlus) to support technology innovation processes. Several complementary features were developed in the ESA module which provides insight into impacts at different levels. At local scale, environmental impacts are assessed in relation to the different design choices using thirteen functions (i.e. Footprint of the array, Collision risk with devices, Collision risk with operating vessels, Energy modification, Reef effect, Reserve effect, Resting place, Chemical pollution, Turbidity, Temperature modification, Electrical fields, Magnetic fields and Underwater noise) that cover various potential pressures induced by the ocean energy array. Moreover, surveys and mitigation measures are provided regarding endangered species potentially present. At global scale, a life cycle assessment is conducted to evaluate the carbon footprint of a project in terms of its contribution to global warming and the cumulative energy demand. Two reference models were used to exemplify the use and relevancy of the different features. Overall the ESA module provides insight and support to the ocean energy sector to achieve sustainable development of marine renewable energies.
