Abstract

Drilling riser is the key equipment that connects subsea wellhead to drilling platform. The security of drilling riser concerns whether the drilling operation can be completed successfully. Drilling riser suffers fatigue damage as a result of its vibration under environmental loads. This paper established nonlinear dynamic analysis method of drilling riser based on pipe-soil interaction in time domain. Rainflow counting method, S-N curve and Miner-Palmgren rule are used to establish fatigue damage model and corresponding computer program is developed. The effects of soil stiffness, wall thickness and welding eccentricity on fatigue damage of drilling riser are derived, which provide theory basis for the design and operation of drilling riser.
