Abstract
In this paper a lumped-mass method is adopted to develop a dynamic nonlinear model for an offshore pipeline installation. The influences of ocean currents and vessel speed are taken into account in the model. The accuracy of the model is validated by comparing the results obtained from the present model and these from a previous model and Offpipe software, respectively. A good agreement is obtained for various pipeline configurations. The effect of vessel speed on S-laying operation is then analyzed using the computational tool developed with the present dynamic model.
