(Continued from issue 104(2006)9, pp 63-67) The high temperatures and high pressures associated with the 30-inch multiphase lines of the Ormen Lange project off Norway crossing very uneven seabed forced a reevaluation of standards addressing allowable pipeline free-span lengths. This second of two articles focuses on particular design parameters for free-spanning HTHP (high temperature-high pressure) pipelines such as Ormen Lange multiphase lines and illuminates a case study of Ormen Lange that can be applied to other HTHP pipelines. The first article examined 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 (Det Norske Veritas) free-span standards.
