Abstract

This paper describes a set of experimental tests of subsea pipeline steel connections under combined forces: one set of force is fatigue load, which is the simulation of the variation caused by currents or waves flowing across pipelines; another set of force is hoop force, which is constant tension force introduced by internal and external pressures. The steel connections are made of two steel plates joined together by single-sided girth welds. One central notch is machined on the weld toe. The specimens under combined forces are compared with those subjected to fatigue loads alone. It is found that the hoop force could affect the fatigue life of subset pipeline steel connections and also reduce the initiation angle of the crack propagation. © 2011 Taylor & Francis Group, London.
