摘要

THE Unity 36-in pipeline was surveyed with an intelligent pig in the Spring of 1998 and in the Spring of 2002. Data were obtained indicating volumetric wall loss of some 30% in localized areas of the import and export risers, which lie next to each other in 150m of seawater directly beneath the Unity platform in the North Sea, This paper describes the post-pigging, externally-applied, high-resolution ultrasonic examinations that were carried out by Veritec Ltd on the pipeline to allow a detailed fitness-for-service analysis and remaining-life assessment to be carried out by AEA Technology.
