Abstract
By placement of a structure on the seabottom, the freefield current pattern is changed. The size and geometrical shape of the structure influence the resulting current pattern. This paper deals with observations of scour around gravity structures, piled structures, and pipelines as well as the experience gained with various scour protection methods. Basic considerations required for estimation of scour potential are included for completeness. The observations show that significant scour occurs mainly in shallow waters, especially in areas with active sand waves where some of the piled structures and pipelines included in this study were located. All the major gravity platforms were in deeper waters which explains the moderate scour observed around these structures. The only exception was a square shaped based which experienced significant scour at the corners. Keywords: offshore structure, erosion, protection, case history, field performance data.
