Description
To examine structural integrity questions arising from the proposed use of high-strength steels in tension leg platforms tension members. Environmental cracking (stress- corrosion cracking and corrosion-fatigue crack growth) will be the major focus of the project. The results will provide engineering criteria relating threshold conditions for the onset of environmental cracking in sea water to design stresses, defect sizes, and cathodic protection parameters for specific classes of high-strength steels.
Latest progress update
Complete. Discussions will be conducted with the Naval Research Laboratory on the possibility of conducting additional tests for the ripple-load conditions.
