3067 Defect assessment in offshore structures

Overview:

Provides an assessment methodology procedure for defects in offshore structures, to supplement the procedure given in BS 7910:1998, Guidance on methods for assessing the acceptability of flaws in fusion welded structures.

The procedure is a set of routines for establishing the structural integrity of welded joints in steel offshore structures, based on current research and best industry practice. It is offshore specific in that it deals with the special characteristics of such structures in terms of detailed design and the nature of the loading in such applications. Routines for assessment of individual joints are combined into system reliability assessments and an overall scheme for inspection and repair. The procedure is supported by a commentary that gives the background to sections of the methodology.
