Abstract

A process and system for applying a liner to an inner surface of a pipeline uses an 'inversion' technique to apply the liner. This involves arranging the liner into everted and non-everted portions and driving the non-everted portion through the pipeline such that it everts and is applied to the inner surface of the pipeline. At least first and second pipeline vehicles are used to drive the non-everted portion of the liner through the pipeline.
