Abstract

See full text

System and method for decommissioning a pipeline. The system comprises mechanical and chemical assemblies. The mechanical assembly includes a main body and a contact assembly. When the mechanical assembly is provided in the pipeline, the contact assembly is configurable to contact with the interior wall of the pipeline. The chemical assembly is arranged serially in line with the mechanical assembly. The chemical assembly includes a front section having a cross-sectional portion and a rear section having a cross-sectional portion. The front and the rear section are arranged in such a way that the cross-sectional portions of the front and the rear section cooperate with the interior wall of the pipeline to form a chamber to house a removal medium. The system and method can effectively and efficiently remove most or all of such residual mercury and/or other toxic substance from the interior wall of the pipeline before abandonment.
