Over the years, many methods, techniques, and technologies have been used to implement oil & Gas pipelines. Most of these techniques and technologies have evolved significantly over the years thereby cutting the cost and easing the process of implementing them. The open cut laying method is still the most popular method for executing the oil & Gas pipelines. The open cut laying method is best suited to unpaved surfaces. It’s very easy to implement in an unpaved ground. This method is suitable for all pipe materials and is most familiar to almost all contractors undertaking some sort of excavation project. Traditional open cut laying is defined as the operation of excavating to the required pipe installation level and then backfilling.
This method is usually the least expensive method if the pipe is located under non?pavement areas such as a front or back yard. The open cut trench method involves excavating down to and exposing the existing pipe so that it can be repaired or replaced and then backfilled. If the open cut trench excavation is located in a non?pavement area the excavation can be backfilled with soil and surface vegetation. When the open cut trench excavation is located under pavement the existing pavement must be saw cut and removed, the excavation filled with granular backfill (compacted stone or sand to prevent settlement), and the pavement must be replaced and the end of the pipe repair or replacement.
