EVALUATION OF FATIGUE CONSIDERATIONS IN THE DESIGN OF FRAMED OFFSHORE STRUCTURES

Fatigue is an important consideration for deep water platforms in hostile environments such as the North Sea and the Tasman Sea. This paper evaluates the implications of the fatigue criteria on platform design using recent experiences with the Maui Platform A, offshore New Zealand. It underlines the importance of realistic fatigue criteria and examines various methods for analysis. The need for estimating appropriate stress concentration factors is illustrated. The impact of fatigue on the weight and cost of the platform is discussed.
