On 20th and 21st November 2023, the MAREWIND consortium met in the headquarters of
Institute of Science and Innovation in Mechanical and Industrial Engineering (INEGI) in Porto (Portugal) to discuss the status of the project.
During the last months
Koshkil,
Lurederra and
Tecnan have been working on the repair and maintenance activities. As a result, they identified novel implementation strategies that have been successfully implemented on larger samples. For more than 8 months,
the treated sample was exposed to outdoor conditions without exhibiting any signs of alteration. In contrast, the untreated sample displayed corrosion damage within the first week of exposure.
Lurederra has also been carrying out the drying and curing evaluation under different conditions of anticorrosion coating, in order to validate its application in different scenarios of humidity and temperature. Consequently, the coatings presented a great performance with
more than 4,200 hours of corrosion resistance. Furthermore, Tecnan has confirmed the antifouling coating properties on real samples, demonstrating repellent effect, accomplished the challenge of upscaling the production of both anticorrosion and antifouling nanocoatings reaching 100L batches. Similarly,
TWI successfully manufactured 100 litres of antierosion/superhydrophobic paint, validating its scalability and completing the 3 coating prototypes envisaged.
Following the validation of the prototype design, manufacturability, survival, and monitoring system with Fiber Optic (FO) sensors,
CETMA proceeded to create two sensorised reinforcement meshes. These meshes had distinct configurations – one for the UHPC floating foundation prototypes and another for the AAC deep foundation prototype. During this period,
ACCIONA has focused on UHPC prototypes design and manufacturing for its final goals:
FO sensors response monitoring and UHPC durability performance in real environment, envisaged to be tested at Gijón Port.
The MAREWIND project is reaching its concluding phase in November 2024. Therefore, full-scale tests are being implemented.
EnerOcean has already conducted multiple real exposure experiments of anticorrosion coatings,
demonstrating that samples coated by TECNAN outperform both uncoated and commercial ones, even with reduced thickness, as indicated by the results. The post-exposure tests indicate a robust corrosion resistance, displaying comparable results in both splash and atmospheric zones. Additionally, there are outstanding outcomes regarding the hardness and adherence of samples, both before and after exposure.
Today,
EireComposites is working on the
validation testing of blade components and manufacture of prototypes. In this context, the full blade prototype production will be soon delivered including is corresponding coated fastening elements (TSF-TECNAN).
