Abstract

See full text

A pipeline is assembled traversing steep terrain by digging a trench down an incline, assembling pipe joints together in proximity to the incline, and then using equipment to push and/or pull the assembled pipe joints down the incline and through the trench while the pipeline is suspended above the bottom of the trench. A series of connected sleds are used to partially carry the load of the assembled pipeline, keep it off the bottom of the trench until it is in place, and permit the installation of supports under it prior to backfilling.
