Project Title: Scour potential evaluation of the Western Irish Sea Mud Belt (SCOPE)
Project Description: Ireland can potentially exploit its offshore wind resource as a sustainable source of clean energy.
However, reliable designs must be provided that minimise the environmental impact. Scour is the process of seabed erosion due to the imposed shear stress generated by seabed current and/or waves and has been identified as a key geological feature of the Irish Sea that could have a constraint on engineering activities (Mellet et al., 2015). The presence of seabed obstructions, such as wind turbine foundations, typically result in localised increases in current velocities and induce scour. Local scour can have a significant impact on foundation design and may impact on habitat conditions. Therefore, it represents a significant geological hazard from an environmental and engineering perspective. The SCOPE project will conduct a scour assessment for the Western Irish Sea Mud Belt; an area that has been identified for offshore wind development and which supports Nephrops fisheries. A significant amount of data that has been gathered for the region will be analysed to identify the potential for scour occurrence. The aim is to establish a geological baseline applicable for future engineering and environmental studies. Guidelines and recommendations for future scour assessments will support sustainable offshore wind development
