Abstract

Jack-up rigs have traditionally been used for short term drilling and maintenance operations. However, they are now being used increasingly as production platforms for marginal field development. The deployment of jack-up platforms for extended periods increases the risk of long term problems such as fatigue due to the reduced frequency of dry dock inspections and the enhanced susceptibility to fatigue crack initiation and propagation. Furthermore, there is less data available on high strength steels used in the fabrication of jack-ups when compared with conventional offshore structural steels such as BS 4360 and BS 7191 and there is no existing fatigue guidance: current fatigue guidance is limited to steels with yield strengths up to 500 MPa. There is need to establish the fatigue behavior of high strength steels used in jack-up construction and this paper presents results from a major large scale fatigue testing program on the fatigue performance of a typical high strength jack-up steel, SE 702, which investigated (a) the effects of cathodic protection on the corrosion fatigue behavior of large-scale high strength welded tubular joints tested under constant amplitude loading, and (b) the corrosion fatigue behavior of the same steel under simulated service loading and environmental conditions. The effects of cathodic protection and variable amplitude loading on the fatigue performance of SE 702 high strength steel are assessed and compared with results from conventional offshore structural steels.
