The second-largest oil spillage in Norwegian petroleum history occurred on 12 December 2007 when the Statfjord A offloading system ruptured. Results of numerical simulations of pressure transients in the offloading system are presented. Of particular interest is the influence of acoustic properties of pipeline sections on propagation of pressure transients. The damaged-offloading-system geometry and characteristics, as well as the acoustic properties, are described. The paper describes numerical simulations of pressure transients in the offloading pipeline. The paper shows how detailed modeling and accurate estimation of acoustic velocities influence local maximum increases in pressure in an offloading system.
