The Production and Testing of MEIDP Line-Pipe for 3500m Application

This paper presents the basic wall thickness design requirements for the Middle East to India Deepwater Pipeline (MEIDP) and tracks the production and subsequent ring collapse testing of this linepipe suitable for 3500m water depth. The test program showed that the ring testing method was well suited to being performed on a production basis and was capable of achieving consistently repeatable collapse capacity results. The ring tests also clearly demonstrate the effect on the collapse capacity of heat soaking the pipeline at simulated 3-Layer coating temperatures. Detailed results of the ring collapse testing both before and after heat soaking will be presented..
