1st Edition, April 2014
The
American Petroleum Institute (API) recently published the first edition of
recommended practice (RP) 1172 for Construction Parallel to Existing
Underground Transmission Pipelines. This new RP is intended as a resource to
assist all parties to safely manage construction activities of new or modified
facilities parallel to existing underground transmission pipelines. Activity of
concern includes construction activity that could impact an existing facility,
such as excavation or movement of equipment across the pipeline or within the
easement that could affect the safe operation of the existing pipeline.
The primary emphasis of these guidelines is on the interaction between existing
transmission pipeline operators and those planning to construct in a parallel
fashion. Contractors working on behalf of the constructing party, including
environmental and survey professionals, design engineers, construction
contractors, and operators of excavation and earth moving equipment, are
encouraged to engage in work practices that are in conformance with these
guidelines. These guidelines have been developed such that they can be
incorporated into contract documents executed with contractors and
subcontractors by whichever party is involved in or responsible for construction
activities.
This RP is available online
at the API Publications Store: Product No. D11721.
