SCOUR AROUND MARINE STRUCTURES
Dealing with scour related problems in water environments

This two-day, thematic course introduces you to the procedures of analysis related to assessing scour risk at marine structures. The focus is on offshore wind turbine foundations and how to protect against or mitigate the scour formation by applying scour protection systems of, for instance, rock dump or mattresses. After the course the participant will be able to identify and define scour issues, asses 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. Scour 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 affects the structure as a whole, including the foundation and the interaction between flow, structure and sea bed to ensure short– and long term stability. Evidently, the formation of scour around marine structures can pose a threat to the structural stability and the cables transporting electricity.

COURSE TOPICS  Flow and force processes in the presence of cylindrical structures  Hydroelastic (flow-induced) vibrations of slender structures such as marine pipelines and flexibly-mounted cylinders  Explain drag, inertia and lift forces in currents and waves  Scour around marine structures including offshore wind turbine foundations, gravity based structures (GBS), cables and pipelines  Scour related problems: depravation of the general sea bed level, migration of large bed forms, edge scour and sinking of scour protections.  Scour in complex soils  Scour protections systems (counter measures): types, rock dump, mats, installation and monitoring  Hands-on exercises including computer simulations in MIKE 21 TARGET GROUP AND PREREQUISITES Professionals in hydraulic or engineering and management working with design, installation and commissioning of marine structures.
