Издание на английском языке
This book is about the fundamental issues relevant to ageing of offshore structures and the necessary considerations for life extension. The aim of the book is to investigate and understand how these structures change with age and how these changes can be managed and mitigated.
The literature on structures is largely aimed at structural design despite the fact that particularly in UK and Norwegian waters over 50% of offshore structures are now in a life extension phase and are experiencing ageing.
