Project Number 81
Date of Summary June 30, 1987
Subject Fatigue of Selected High Strength Steels in Sea Water
Performing Activity Florida Atlantic University
Principal Investigator Dr. William H. Hartt
Contracting Agency Minerals Management Service
Estimated Completion Complete
Description The objective was to characterize the fatigue properties of several high strength steels (yield stress in the range 60-130 ksi) which are being proposed for deep ocean oil and gas facilities. These materials were to be tested under conditions which are applicable to the service status of offshore structures. The materials were characterized according to the influence of environmental and load variables upon their engineering properties. This was a Joint Industry Project (JIP).
Progress Complete. The final report has been submitted and accepted.
