MarTERA:AQUACULTURE OPERATIONS with RELIABLE FLEXIBLE SHIELDING TECHNOLOGIES for PREVENTION of INFESTATION in OFFSHORE AND COASTAL AREAS


Description:

As the aquaculture industry continues to expand, fish farm operators are looking to adopt new technologies to ensure that the quality of fish cultivation reaches the highest standards and production efficiency is maximised. The FlexAqua project will address the key knowledge gaps related to the growing use of new shielding solutions, to prevent parasites infestation. These shielding technologies are of two types: parasites-barrier skirt and snorkel cages. The project will generate knowledge to prevent breakdown of these new farming systems which could lead to fish escapees. Parameters like sea states (currents and waves) and effect of marine organisms will be investigated. A novel Fluid-Structure Interaction (FSI) analysis will be carry out on these flexible structures to predict hydrodynamic loading and structural behaviour under a range of sea states, which is of growing interest as aquaculture production extends to high-energy sites and so towards under severe environmental loading for structures. The effect of marine growth colonisation on the forces acting on these farming systems will be explored by using novel 3D imaging techniques and which will be used to develop more accurate and realistic FSI setups. New image processing techniques will be developed for detecting and monitoring damages such as corrosion, cracks and net defects. Finally, an adapted sensors deployment strategy will be devised for cost efficient structural health monitoring of these complex flexible marine infrastructures. Overall, this project will shed light on the long-term performance of these new shielding designs under various sea conditions and will develop effective monitoring strategies and damage detection techniques to help ensure structural integrity is maintained during the in-service life of these structures
