Middle scale test on dry coatings and connections

The report of deliverable 6.1 will be split into 2 parts:The first part will present the results of the performance tests on dry coating in realistic offshore conditions and on larger samples.After the coupon level evaluations performed un WP2, several larger scale tests will be conduct. The configurations to be tested will be selected according to the WP2 outputs. Samples with and without integrated sensors will be compared as well. Recommendations for improvement of the process for both adhesive paint film and in-mold paint film will be done in accordance with the results. For emerged composite parts, a natural outdoor exposure site will be used. This consists in an exposition in open air or under shelters in a tempered marine atmosphere site. Various exposure angles can be chosen (45° south, 5° south, 90° north) and all the conditions are properly monitored. For immersed composite parts, tests in natural seawater will be conduct. The water can be regulated in temperature, oxygen and biological content. This test is performed on land and is able to give representative data on the durability and biofouling behavior of the products. The second part of the deliverable will presents the results from the static and dynamic tests performed for selected adhesive connections. Then, the reduction factors, used for a complete fatigue calculation, will be determined and presented. And finally, in the case of reversible structural adhesive, results going from the comparison with traditional adhesives until the capacity to recycle them, evaluating the heat energy and the time needed to separate the bonded joint, will be presented.

Guidance notes for the production of large FPR OWTP

Description of the technologies and processes developed in the project for the production of the targeted OWTP platforms as well as manufacturing strategies for modular production. Furthermore, it will also contain a brief summary of the two open-door daysand workshops, which will be organized

Multifunctional materials for SHM diagnosis and structural performance assessment

This report will evaluate the structural health monitoring (SHM) methodology developed in the framework of FIBREGY to obtain the damage state of the fibre-based structural elements used in offshore platforms.The non-destructive vibration-based methodology deals with the variations of the key performance indicators (KPIs, e.g. overall vibration energy, damping, etc.) which are influenced by the presence of damage in the FRP materials. To assess the damage state of the multifunctional materials, a set of sensors and/or optical fibers will be interleaved in the interlaminar regions of the FRP-based materials used in the marine structures. Initially, the main scope of this report is to explore the selection of the most suitable sensors to manufacture the multifunctional materials. Subsequently, the mechanical performance of the multifunctional materials will be analyzed with the paramount purpose to evaluate the possible weakness of the material induced by the embedding of the sensor. Last, it will be considered the testing of different specimens of multifunctional materials and the preparation of the best strategy for the validation of the monitoring system in a real-case through one of the WP6 demonstrators (FRP-based towers).

Project guidelines and recommendations for using FRP in large OWTPs

This report will gather recommendations and procedures to be considered in the analysis of predictive maintenance in OWT platforms built in FRP materials, considering the different SHM strategies, instrumentation and a digital twin models developed in the context of FIBREGY.It should be noted that the diagnosis of the marine offshore structures will be based on the variations of various key performance indicators (KPIs), which will provide real-time information about the damage state and structural condition of the offshore platforms, including KPIs related to the onboard equipment and systems if needed.Special attention will be also paid to the optimum number and location of the sensors to be embedded in the offshore platforms.

Development of the CAE models

The report will summarize the work to be carried out in subtask 6.3.1, related to the generation of two complete 3D CAE models of the structure of the W2Power platform and TIDETEC turbine housing, based on the hydro-elasticity and degradation model developed in WP3. These models will be used in WP4 to perform a final strength and degradation assessment of the structure.

Fatigue performance of composites

The deliverable will present the results and conclusions of the different fatigue tests to be performed.An interim report will be delivered by month M24 describing the regular fatigue tests (O° and 90° lay-ups) and results. This data is the only one required by the numerical models for material calibration.The report will be completed by M29, including the advanced fatigue characterization performed on oblique (45°) lay-ups and also the connections.

Environmental protection of composites

The report of deliverable D2.3 includes all the results of the durability tests performed during the extensive experimental campaign.

The durability will be evaluated for the following configurations:- At least 2 paint references (from 2 suppliers or 2 different chemistries)- At least 2 composite substrates (1 thermoset and 1 thermoplastic)- Three types of application: adhesive paint film, in-mold application of paint film and stand ard liquid paint application- Three surfaces textures: flat surface and two fouling release textures- Unprotected composite samples as a comparison

Critical review of applicable standards and gaps identification in FRP offshore structures (T4.3.1)

The conclusions of an extensive review of the regulations and standards related to the use of conventional (steel and concrete) and unconventional materials (FRP materials and others) on marine structures will be included in this report, as well as the gaps that need to be filled in in the future by regulatory bodies to enable the rolling out of OWTP platforms in FRP materials. A two-tier strategy will be performed with the fundamental objective to carry out the critical review. Firstly, it will be carried out an analysis of the potential standards for the application of FRP materials in the design of offshore structures. Secondly, it will be identified the existing gaps for the application of FRP materials in the design of the W2Power and the TIDETEC’s turntable tidal turbine developed in FIBREGY. The findings of this report will be used as the background of the deliverable 4.7 focused on the development of project design guidelines and recommendations for using FRP in large OWTPs.
