Abstract

A series of fatigue tests were conducted on T-butt-welded specimens made from high strength (SE702) jack-up steel. Fatigue tests were conducted using a pseudo-random sequence (JOSH) designed to give typical jack-up loading at two levels of cathodic protection. The results are presented in terms of fatigue life and crack growth evolution. The results for the T-butt joints were compared to tubular joint fatigue test data obtained with conventional fixed platform steels (BS4360 GrSOD) and the same high strength steel (SE702). The study indicated that for high strength steel joints with relatively short fatigue lives the influence of the cathodic protection level is quite small and the fatigue resistance is slightly better than that of joints fabricated from conventional structural steels such as BS4360 50D.
