Seabed scour by currents near platforms
The gravity platforms in the North Sea, sitting directly on granular seabeds, may be undercut by scour and need scour protection. Conventional methods of protections are developed for structures 1or 2 orders of magnitude smaller and seem unnecessarily conservative when scaled to these larger sizes....
