A major testing campaign and research program conducted around the Ormen Lange project off Norway sought to develop subsea long free-span design procedures in compliance with Det Norske Veritas standard DNV-RP-F105 design philospphy in an affort to minimize free-span intervention costs. This first of two articles examines the shortfalls of existing standards as applied to Ormen Lange, as well as the testing and analysis that ultimately not only helped determine the route of the Ormen Lange export pipeline but also led to an update of DNV free-span standards. The second article will focus on particular design parameters for free-spanning HTHP (high temperature-high pressure) pipelines such as Ormen Lange and illuminate a case study of Ormen Lange that can be applied to other HTHP pipelines.
