Serial progress meetings

Real time for discussion on the progress made and essential project management tools, the progress meetings punctuated January. Four projects were concerned: BENTHOSCOPE2, CARAVELE, INDUSCOL et MHM-EMR.


This project aims to test the use of passive acoustic tools in the context of an impact study of an ORE project. At the same time, he is interested in the acoustic impacts of ORE on benthos. An instrumented measurement platform (acoustic, video, salinity, temperature...) has been developed to correlate the sounds emitted by benthic animals with their living conditions. To this end, an annual environmental monitoring is carried out at the Sainte-Anne du Portzic site, near Brest.
During the meeting, a large part of the exchanges concerned the experiments carried out last autumn. The goal: to determine acoustic indicators for different benthic habitats and "inhabitants".


The purpose of this project is to study the life span of structural composite bonding immersed in the ORE sector. As glue joints are thin, the integration of sensors to ensure this monitoring without altering the properties of the joint represents a technical challenge.
The monitoring experiments carried out at the glue/structure interface are very promising. They will soon be the subject of scientific publications.

Le 21/01 : CARAVELE

The objective of this project is to improve wind characterization in order to reduce uncertainties in resource assessment and wind turbine design. To this end, a joint exploitation of modelled wind fields, satellite images and in situ observations is currently being carried out.
During the meeting, the main topics discussed were the use of satellite images and work to improve the vertical variability of the offshore wind resource.

21/01: MHM-EMR

This project aims to define an in-service monitoring methodology using a hybrid monitoring/digital model approach for anchor lines of EMR systems falling into the category of "digital twin" models. The objectives: to anticipate risks, to reduce the uncertainty of estimating the lifetime of mooring components and thus to optimize the maintenance plan.
The meeting was an opportunity for intense discussions on the specificities of the different floating EMR technologies according to the float, their anchoring and the water depth. From a methodological point of view, key monitoring parameters are identified and long term identification strategies are implemented by integrating the constraints of indirect measurements but also the weather conditions that are experienced and not chosen. The work plan includes identifying the impact of the measurement quality on the model in order to define confidence indices.
