Abstract
Access and connection for a buried pipeline, wherein a hole is dug to a buried pipeline, a riser pipe is disposed within the hole, and one or more powered tools are lowered into the hole and activated such that work is performed on the pipeline without the need for anyone to be lowered into the hole. Because no one needs to be physically present down in the hole at the pipeline, the hole, and thus the surface disturbance can be much smaller than conventional pipeline work methods.
