GN2 was contracted to identify the root cause of bolt up stresses observed in some existing pipelines. GN2 developed multiple engineered piping solutions to mitigate the stress and produced construction packages to implement these engineered solutions in the pipelines of concern. This included the installation of bends with tight angular tolerances, installation of rubber hoses, modification of existing pipe supports, and the modification to secondary lines and takeoffs tied into the main pipelines. Civil modifications were completed to improve access for Maintenance Crews and to further mitigate risks with pipeline maintenance activities.
