New international pipeline codes - Did they meet the expectations?

This paper sums up the background and motivation for developing international pipeline codes i.e. basically the new ISO 13623 and the DNV-OS-F101 Pipeline Standards. The recent developments that have taken place are focused. Basic aspects of pipeline code development are discussed on a general basis as are the various aspects of selecting the appropriate code in a specific case. The experiences made in international use of these codes are discussed on the basis of some major pipeline projects where these codes have been applied. The discussion aims at coming up with answers to questions like: Did the codes meet the expectations as to international acceptance? To what extent have they been taken into use? Is there an optimum code to be selected for a pipeline project? The impact by the new pipeline codes on pipeline integrity management is discussed on a general basis.
