Gullfaks Gas Export Phase II 11″ X 12″ X 14″ Pig

The Gullfaks Satellites Phase II pig development was a fast track Multidiameter pig development for Statoil. This demanded that in order to short track the testing, the right components were required to be on site when testing begun so that the correct solution could be converged on. Pipeline Research Limited provided the design of the main 14″ sealing disks that were again design to buckle in the smaller lines and seal correctly in the 14″ line.

Additionally, modeling of the pig as a whole in the 14″ line allowed a stable pig to be developed. We have since learned that this pig has been used successfully in the pre-commissioning of this pipeline.
