Fatigue damage in offshore structures---causes, detection and repair. A. Stacey and J.V. Sharp. Paper. BOSS '97, Vol. 3, pages 77--91. (See abstract 393 for complete reference).
Consideration is given to the types of fatigue cracking that have occurred offshore to date. The regulatory framework is outlined, and in-service fatigue to offshore structures is discussed. The principal causes of fatigue damage to fixed steel platforms in the UK sector of the North Sea being fabrication defects, including weld root defects, followed by fatigue; environmental fatigue loading; and damage from pile driving followed by fatigue. Inspection and maintenance are also discussed. 23 refs.
