FATIGUE DESIGN AND ANALYSIS FOR WELDED TUBULAR JOINTS: RESULTS FROM THE API OFFSHORE TUBULAR JOINTS RESEARCH CENTRE

The fatigue performance of tubular connections can limit the life of offshore constructions. Fatigue research for the American Petroleum Institute (API) Offshore Tubular Joints Research Centre focused in its first three projects on fatigue design. An examination of design rules in API RP2A and equivalent standards as well as the basic data has defined several areas where API RP2A can be updated to include new design curves and explicit means of determining hot spot stresses. In addition, several suggestions have been made that would introduce new provisions, such as inclusion of other weld improvements besides grinding and a different method of including the effects of cathodic protection in seawater.
