System and method for elongate pipeline manufacturing in-situ

A mobile pipeline extrusion method, comprising:

• a. providing a first mobile vehicle having a first electromechanical drive system and a first active suspension configured to stabilize the first mobile vehicle relative to terrain over which it may be navigated, a second mobile vehicle removably coupleable to the first mobile vehicle and having a second electromechanical drive system and a second active suspension configured to stabilize the second mobile vehicle relative to terrain over which it may be navigated, a computing system operably coupled to the first and second mobile vehicles and configured to operate the first and second electromechanical drive systems and first and second active suspensions such that the first and second mobile vehicles may move together in an end-to-end coupling configuration as a unified operational platform, and a polymeric pipeline extrusion system operatively coupled to the unified operational platform and configured to receive input materials, heat the input materials, process the input materials through an extrusion die, and produce an output pipeline;
• and
• b. navigating the unified operational platform forward while outputting the output pipeline at a selectable output length.
