Claim 11:
12. A system, comprising:
an existing product pipeline having a first end, a second end, and a middle section, in which the middle section is below ground and the first and second ends are exposed to an above-ground environment; and
a pipe twisting device supported at the first end of the product pipeline and configured to apply a torsional force to the product pipeline such that at least a portion of the product pipeline is torsionally deformed;
in which an outer surface of the product pipeline has a longitudinal pipe axis; and in which the pipe twisting device is configured to torsionally deform the product pipeline such that at least a portion of the longitudinal pipe axis has a helical shape after torsional force is applied to the product pipeline.
