Offshore structures have been built in steel or concrete. With steel, new design concepts are necessary as the water depths increase. The so called hybrid design of tubular joints with cast steel inserts moves the fatigue critical welds away from a highly stressed region. The object of the present research project was an investigation of this design concept for higher strength steels and reduced wall thickness under offshore-typical corrosive and fatigue loading. Compared to previous investigations with StE 355 for the tubulars and GS - 8 Mn 7 for the cast insert (wall thickness 38 mm)m, this investigation employed the high-strength steel StE 500 for the tubulars and the new cast steel GS -12 MnMo 7 4 (wall thickness 28 mm).
