The plane frame version of a steel jacket platform is analysed by mode acceleration method. The local stresses in the joints of an offshore structure subjected to random wave/current load are derived from the nominal stress response of the structural members using the stress concentration factors.

Creep Damage and Creep-Fatigue Damage
2011A time-dependent deformation occurring in a material subject to load for a prolonged period of time is called creep. In a narrower sense, creep means a time-dependent deformation caused by a constant stress or a constant load. Materials undergoing creep for long time are often accompanied by time dependent internal deterioration.

A conceptual definition of fatigue damage is proposed to assist in the selection of measurement techniques and parameters for correlating damage with fatigue life. To illustrate the concept, a critical review of some typical damage parameters for composite materials is given.

Cumulative damage in fatigue is a problem which in recent years has become of interest to designers in almost all branches of structural engineering. To the aircraft designer however — especially under present-day conditions of operation — it is of paramount importance.

Relationships between the characterization and the nondestructive detection of fatigue damage are discussed and illustrated. Inspection methods presently used at overhaul facilities are reviewed, and examples of the equipment used and the results obtained are given. The advantages and limitations of currently used nondestructive methods are summarized.

Abstract This chapter addresses the cumulative effects of fatigue and how to determine its impact on component lifetime and performance. It begins by defining a loading history and its corresponding hysteresis loops that exposes the deficiencies of some of the theories discussed.

Neural networks on fatigue damage prediction
Proceedings of International Conference on Neural Networks (ICNN'97), 2002This paper introduces a new methodology for fatigue evaluation of tubular offshore structures. The accumulated fatigue damage on selected joints, caused by actual wave loading condition, is assessed through a data acquisition and processing system, based on a PC microcomputer, installed onboard. By measuring the upward jacket displacements and applying
