OUR OFFER
Project management assistance for consultancy firms, farm and technology developers in the characterisation of biofouling and the deployment of measuring buoys on site
- Identification of system components sensitive to biofouling, definition of dedicated characterisation and monitoring protocols
- Dynamic design of buoy + anchor systems
- Proposal of biofouling sampling solutions, management of subcontracting for the construction and assembly of the devices, definition of adapted installation procedures and selection of service providers
- Follow-up of installations once deployed at sea
- Analysis of the data collected for translation into parameters that can be used for engineering purposes
OUR REFERENCES
Several R&D projects dealing with the characterisation of biofouling and/or requiring the deployment of buoys for measurement
- Development of biofouling characterisation protocols and analytical methods for engineering (ABIOP+ project)
- Characterisation of biofouling on the tidal site of Ria d’Etel (ELEMENT project)
- Constitution of a hydrodynamic database in the presence of full scale macrofouling (OMDYN2 project)
- Deployment of a special brand instrumented buoy and a wave recorder on the Mistral test site (MEMOFLOW observatory)
- Design of the mooring system and deployment of a measuring buoy on the site of the future floating wind pilot farm at Groix & Belle-île (APPEAL and ABIOP+ project)
- Validation with sea trials of tools for modelling the mechanical behaviour of nylon fibre lines (MONAMOOR project)
OUR RESOURCES
Teams with complementary and cross-disciplinary expertise: physical oceanography, structure calculation, offshore monitoring, marine biology and ecology
Dedicated instrumentation
- Stereo video cameras to film waves propagation in real time and in 3D in a 100 m square
- 4 measuring cages and instruments that can be attached to them: ADCP 5-beam, hydrophones, acoustic receivers, stereo video, camera, multi-parameter probes
- Video system with anti-fouling protection that can be deployed up to 200 m depth
- Structure for the deployment at sea of mooring line coupons
Digital tools
- DeepLinesTM licence
- Nylon anchor line behaviour module interfaced with DeepLinesTM
- NEMOH for the seakeeping of the floats
Databases
- Alderney Race: hydrosedimentary processes, high-resolution measurement of currents and turbulence
- Biofouling along the French coasts : protocols, measured data and data from the literature
- Hydrodynamic tests: loads in the presence of full scale macrofouling in current only and oscillating flow with and without current
