(Continued from issue 103(2005)43, pp. 66-70) Statoil has extensive experience in both dual-diameter pigging of subsea pipelines and the environmental ramifications of pipeline commissioning. This second article in a two-part series discusses pig design for dual-diameter systems and the environmental aspects of commissioning operations, presenting relevant field experience. This concluding article also elaborates on Statoil's commissioning concept for the 1,200-km Langeled project from Norway to the UK, scheduled for commissioning in 2006 to 2007. The first part of this series (OGJ, November 21, 2005, p.66) discussed commissioning concepts for single and multidiameter pipelines; air drying of internally coated, export-gas-quality pipelines; and dewatering of pipelines with hydrocarbon gas.
