Subsea pipelines have been used to carry oil or gas produced from fields that lie under the sea to shore. The girth welds in subsea pipelines are subjected to combined stresses in most of their service life. However, limited research was reported on fatigue crack growth for connections under such combined loads. This paper summarizes a recent study on fatigue of subsea pipelines under combined actions. It covers the prediction of natural frequency, stress analysis, fatigue testing, prediction and numerical simulation of fatigue life. Finally the carbon fibre reinforced polymer (CFRP) strengthening technique to improve the fatigue life of such connections is presented.
