This report will evaluate the structural health monitoring SHM methodology developed in the framework of FIBREGY to obtain the damage state of the fibrebased structural elements used in offshore platformsThe nondestructive vibrationbased methodology deals with the variations of the key performance indicators KPIs eg 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 andor optical fibers will be interleaved in the interlaminar regions of the FRPbased 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 realcase through one of the WP6 demonstrators FRPbased towers
Connections in offshore structuresReport containing a benchmark of the connection technologies in OWTP structures their respective evaluation and selection The report will also include the redesign andoptimization of the most promising connections supported by a detailed description of the experimental testing campaign
Development of the CAE modelsThe report will summarize the work to be carried out in subtask 631 related to the generation of two complete 3D CAE models of the structure of the W2Power platform and TIDETEC turbine housing based on the hydroelasticity and degradation model developed in WP3 These models will be used in WP4 to perform a final strength and degradation assessment of the structure
Environmental protection of compositesThe report of deliverable D23 includes all the results of the durability tests performed during the extensive experimental campaign The most relevant laboratory tests to evaluate the environmental performance of the various solutions are listed below Alternate and continuous immersion in salt solution ISO 11130 ISO 2812 High Humidity Test ISO 6270 500 hours at 40 C and 98 HR QUV accelerated weathering test ISO 11507 1000 hours with cycles of 4 hours UV light 4 hours of high humidity Climatic chamber with thermal cycles 20C 80C Adhesion tests Cross Cut ISO 2409 and Pull Off ISO 4624 before and after each ageing test Gloss ISO 2813 and Colorimetry ISO 7724 measurements before and after each ageing test Observation of visual defects before and after each ageing test The effect on the texture on biofouling will be evaluated at coupon level in natural sea water basin A dedicated Design of Experiments DOE will be built to optimize the number of samples to be tested 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 inmold 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 twotier 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 TIDETECs turntable tidal turbine developed in FIBREGY The findings of this report will be used as the background of the deliverable 47 focused on the development of project design guidelines and recommendations for using FRP in large OWTPs
After 6 months the first information day will be the first joint meeting of the entire project consortium A presence event is currently assumed Should the situation CovidPandemic make it necessary for the event to be held virtually the agenda will be adjusted if necessary 1 to 1 12 days are estimated for this information day The meeting will take place at one of the project partners It starts at noon on the first day The first day ends with a consortiumdinner The meeting will continue on the second dayIn terms of content the focus will be on the following points Presentation of the project objectives of the project progress and the expected results During the meeting the first results of the ongoing and possibly completed WPs should be presented There is also a workshop with the Standardization Committee D73 planned In addition to the purely professional exchange the meeting also allows you to get to know the project partners personally
