This two-day course, jointly organised by BM SUMER Consultancy & Research and The Academy by DHI introduces you to the physics of scour and procedures of analyses related to assessing scour risk at marine structures. The focus is on scour processes in various flow environments with structures such as pipelines, piles, pile groups, breakwaters, etc.. There is particular emphasis on offshore wind turbine foundations, including on how to protect against or mitigate the scour formation by applying scour protection systems of, for instance, rock dump or mattresses. Upon completion of course the participant will be able to identify and define scour issues, assess the risk of scour and possible mitigation solutions for various types of marine structures, and obtain the recent knowledge gained over the last decade from significant development and research within the field of marine scour.
Scour is a well-known issue for hydraulic and marine engineering, which occurs when structures are placed on erodible beds and exposed to current and waves. The foundations of e.g. offshore wind turbines are often erected in harsh hydrodynamic environments, exposed to tidal currents and large waves individually or in combination. Therefore, it is essential to have a detailed understanding of how these hydrodynamic environments affect the structure as a whole, including the foundation and the interaction between flow, structure and sea bed to ensure short– and long–term stability. This course essentially addresses these issues.
- Basic concepts
- Scour under pipelines: piles/bridge piers, including large piles; pile groups/complex structures; and breakwater and seawalls
- Numerical modelling of scour, using advanced CFD models; recent advances
- Transience in scour due to environmental forcing including long term changes, effect of migrating bed forms and seabed lowering
- Scour protection measures; static and dynamic designs of rock dump
- Dynamic responses of scour protections: (1) cover stones stability, (2) winnowing failure, and (3) Edge scour and falling apron behaviours
- Time-integrated design of scour and scour protections
- Scour assessment in MIKE21
- Various case studies
- Monitoring of scour
