The work undertaken in this project encompassed four topics. The first concerned stress corrosion cracking of offshore steels. An experimental programme designed to compare several test procedures commonly used to evaluate stress corrosion cracking properties was performed on a pipeline and a casing steel suitable for offshore applications. Further experimentation on steels containing various levels of nickel was also performed. In the area of threshold fatigue behaviour under variable amplitude loading, fatigue crack growth threshold values were measured for a BS4360 Grade 50DD steel under both constant and variable amplitude loading. A number of variables were studied - the loading frequency, environment, R-ratio and for the variable amplitude loading, the effect of block length. 150mm thick welded cruciform joints were tested in air under constant amplitude loading, to provide data concerning the effect of section size upon the fatigue behaviour of thick section welded joints. The fatigue properties of welded joints between rolled and higher strength steels and both cast and forged steels were tested under constant amplitude fatigue loading.
