Developing a suitable pipe line pig for the Zeepipe gas transportation system required extensive research and testing. Initial concern focused on the need for an adequate seal to prevent gas by-passing into the dewatering train during commissioning of the 506-mi phase one section between the Sleipner platform and onshore terminal at Zeebrugge, Belgium. Based on extensive test results, it was concluded that pigging and start-up on single pipe line sections of more than 620 mi was feasible, providing the line is internally coated, and sufficient precautions are taken during construction to avoid excessive amounts of debris being retained in the line. Zeepipe is being developed to deliver gas from various fields in the North Sea to continental Europe. Fully extended, it is the world's largest offshore transportation system, consisting of more than 1,244 mi of 40-in. subsea pipe. The system is being built by Statoil on behalf of the Zeepipe joint venture. The first development phase includes the 506-mi section from the Sleipner field to Zeebrugge.
