CORROSION FATIGUE CRACK PROPAGATION TESTS ON STEELS FOR OFFSHORE STRUCTURES

The importance of research work on fatigue of deepwater offshore structures is discussed in the context of the special operating conditions for such structures. Problems in establishing realistic conditions for fatigue tests, and the possibilities afforded by the application of fracture mechanics are indicated. The need for more research in several areas is emphasized. Experimental investigations, in which the effect on crack growth of cathodic protection and narrow band random loading were studied, are described. The experimental conditions and an unconventional test specimen containing six cracks are discussed. Some early test results are given.
