Life extension of offshore structures : A conceptual framework and fatigue damage models

PhD thesis in Offshore technology Many offshore structures worldwide are approaching or have already exceeded their original design life. It is important to use the existing infrastructure efficiently and to estimate remaining service life accurately. Fatigue and corrosion are identified as main age...
