WELD DEFECT DISTRIBUTIONS IN OFFSHORE PLATFORMS AND THEIR RELEVANCE TO RELIABILITY STUDIES, QUALITY CONTROL AND IN-SERVICE INSPECTION

The paper presents analyses of NDT data from a total of more than 250 m of welding in node connections in tubulars in different structures. The weld defect information has been analysed in terms of type, size, position and distribution. A system for coding NDT information and storing it in a data bank has been devised. The analyses show that the distribution of defect size can be described by an exponential or a weibull distribution. It is concluded that it is possible to define the weld defect pattern in an offshore platform in a suitable way for reliability analysis.
