Lastly, we focus on eco-friendly scour protection methods. Nature-inclusive design of scour protections is aimed at increasing the potential ecological value that wind farms add to marine environment, by providing shelter for target species or by contributing to restoration of previously booming reefs that degraded due to human pressure, like in the North Sea. In JIP HaSPro we build an ecological framework that accounts for the existing legislation and guidelines and provides a consolidated basis for the offshore wind industry to make choices concerning all phases of nature-inclusive design (design, construction & operation and decommissioning). Furthermore, we test the hydraulic stability and overall performance of scour protections that include ecological elements like shells and reefballs.

The deliverables of the JIP HaSPro include new design formulae, an online digital handbook of best practices and an engineering software tool for the considered scour protection methods during this research project. Moreover, a large database with model test results, containing 3D-data of scour protection layouts and deformation patterns, as well as a 3D-viewer to visualize these results are included in the deliverables of this Joint Industry Project.
Timeline
JIP HaSPro was initiated in on 1 -9-September 2016 and will be in progress until 1 -6-June 2020. Results will be confidential for a certain period which typically is 2 years after the end of the projectuntil 1 September 2021. JIP HaSPro is still open for new participants that want to join.
