One exemplary embodiment of a high pressure tank and a method thereof includes providing a liner of the high pressure tank. Electronic starter and steering locking device. The generally non-stretchable strap restricts longitudinal over-expansion during positioning and inflation of the liner assembly within a pipeline. , such as less than 5 mW, or to a level defined as safe for the detected approach distance. Where incremental movement of points results in coming within acceptable proximity before acceptable yield is reached, the point is flagged for further consideration. The recovery regeneration control is carried out at exhaust gas temperature lower than that of the non-operation regeneration control while taking time longer than that of the non-operation regeneration control.
