abstract

The HotPipe Project is a Joint Industry Research and Development Project, whose overall objective is to prepare a DNV Recommended Practice, to be used in the verification and design of high temperature/high pressure pipelines. The design guideline will cover most practical cases where pipelines are subjected to high internal pressure and high temperature i.e. exposed pipeline laid in a flat or uneven seabottom and buried pipes. The design criteria are based on the application of reliability methods to calibrate the partial safety factors involved. In this paper, the analysis methodology, the design procedures and relevant design criteria/functional checks for pipeline laid on uneven seabed, developed in the HotPipe Joint Industry Project, are discussed.
