Description
The objective was to assess and characterize the fatigue properties of several new high strength structural steels under consideration for innovative offshore structures in conditions which are applicable to their use. The project was a Joint Industry Project (JIP) with six industry participants and support from the American Petroleum Institute (API).
Latest progress update
Completed. The project determined whether the proposed high strength steels are more susceptible to environmental degradation and to hydrogen damage than conventional structural steels used offshore, and developed near threshold fatigue crack growth rate data.
