FONDEOL2

Participants : Dominique Siegert, Ivan Guéguen.

• Type: Region

• Objectif: wind turbines SHM

• Duration: June 2011 to June 2014

• Coordinator: STX France

• Partners: IFSTTAR, Central School of Nantes and EGIS

• Inria contact: Ivan Guéguen

• Abstract: The project involves innovation supports and foundations for offshore wind around 5 lots representing the issues of the project:

  • Lot 1: The design methodology

  • Lot 2: Design, calculation, execution and control of offshore foundations

  • Lot 3: Structural supports remote monitoring of wind

  • Lot 4: Eco-design of supports and foundations for wind jacket and gravity

  • Lot 5: Integration of noise reduction during pile installation in foundation design jacket

  We are interested in the problem of Lot 3, structural monitoring of wind turbine supports. This lot covers an area of research in full expansion, commonly known as Structural Health Monitoring (SHM).

MAG2C-Pont Tabarly

Participant : Ivan Guéguen.

• Type: GIS

• Objectif: bridge instrumentation

• Duration: Since 2014

• Coordinator : LIRGEC

• Partners: IFSTTAR, CSTB, Nantes Métropole, Université de Nantes

• Inria contact: Ivan Guéguen

• Abstract: The project deals with the instrumentation of the Tabarly Bridge.

  The instrumentation auscultates globally the structure, a structural defect in a given location changes its modal parameters and thus the vibration behavior. Then it can be detected on any part of the structure with an accelerometer. These measures coupled with a wireless data transmission system type or wifi 3g will allow remote monitoring of the evolution of the structure. And where appropriate, to deploy when necessary, for maintenance. The different objectives are

  • Experimentation on a bridge

  • Equipment qualification in real conditions over the long term

  • Apply different vibration processing algorithms

  • Surveillance and Detection

  • Measurement database

  The instrument proposed is based on an accelerometer-based distributed network on the structure. This assembly is connected to a data acquisition system and a modem 3g for continuous measurements and remotely. The vibration will be collectable on the internet.
