Periodic Reporting for period 2 - MAREWIND (MAterials solutions for cost Reduction and Extended service life on WIND off-shore facilities)
Période du rapport: 2022-06-01 au 2023-11-30
MAREWIND addresses the main aspects related to materials durability and maintenance in offshore structures which consequently imply failures, misfunctioning, loss of efficiency in energy generation and which have a major repercussion on O&M and CAPEX. With the combined forces of key-players in the current value chain of wind energy and offshore structures, MAREWIND covers a set of ambitious targets focused on: (a) increased durability of both functional and structural components, (b) smart materials and monitoring including predictive modelling (c) lightweight materials and (d) increase recyclability of materials and components. These five objectives will be developed considering three main pillars addressing all those aspects related to (1) Scalable manufacturing technologies and easy to repair solutions, (2) Safer-by-design materials avoiding environmental concerns and ocean impacts and (3) Standardisation aspects for effective European deployment of marketable and usable technologies.
The following specific objectives are set:
Objective 1: Increasing durability/anticorrosion of metallic materials for atmospheric and splash areas
Objective 2: Increasing durability of non-metallic materials for structural components
Objective 3: Long-term durability of antifouling coatings without biocides
Objective 4: Increasing stiffness and strength and reducing weight of larger blades
Objective 5: Leading-edge protection systems with increased erosion resistance
Objective 6: Monitoring and predicting structural health and corrosion for preventive maintenance
Objective 7: Implementing circular use of blade materials at prototype level
Objective 8: Demonstrating scalable manufacturing technologies
Objective 9: Standardisation and regulation
Objective 10: Assessing the economic viability, environmental and social impact of the proposed solutions
MAREWIND is divided in eight WPs. During first 18 Month of the project WP1 Definition of requirements and WP2 Fabrication and testing elements individually have been completed and Milestone 2 (M2- Selected formulation passing relevant laboratory standards and characterisation) was reached. WP3 Structural Health Monitoring (SHM) tools and predictive modelling for preventive maintenance of wind energy has drawn on 85% at Month 36 and Milestone 1 (M1- Initial data from the models previous to validation) was reached on Month 12.
WP4 Techcnologies Validation and Manufacturing started on Month 16 and fisnished on Month 36 on which Milestones 3 and 4 have been reached with validation of technologies and construction of prototypes to be tested in WP5. WP5 "Technologies demonstration in relevant environment" started on Month 30 and the testing on sites selected as relevant environment has started.
On WP6 Technical Validation of results LCC, LCCA & SLCA first results have been obtained on execution of the workpackage. Work of all the partners has been of main importance on WP7 Dissemination, exploitation and Stakeholder Engagement, covering all the value chain. WP8 day to day and overall project management has been carried out during Month 19 to Month 36 of the project, including also Data Management Plan (DMP).
MAREWIND project will work on different materials and technologies as costs associated with this are also important. The technology concepts of MAREWIND linked to previous research knowledge and activities within the consortium are based on: anticorrosion protection for metallic elements, increasing durability and corrosion resistance of non-metallic materials for structural components, antifouling coatings in steel componenets and polymeric elements, increasing mechanical performane of larger blades, recyclable by-design materials, supporting monitoring and modelling and in situ repair technologies.
