About Us

USA Mainline Construction Services, Inc., a subsidiary of EMS Group I, was conceived to and is being developed into an organization that will be able to construct and/or install infrastructure that is required to transport natural gas, crude oil, petroleum products or any other energy related product needed to fuel the vast energy driven industry in the USA and other countries of the world.

This infrastructure includes; larger diameter/longer pipelines, compressors and pumping facilities, and interconnects to marketing mediums.  The “mainline” is the segment of the system that connects the energy/petroleum gathering pipelines for transportation of product to markets.  Gathering systems originate, generally, from oil/gas wells, usually many miles from the ultimate market.  The “mainline” can also originate from refiners, oil/product storage (tanks and underground) facilities, LNG regasification plants, natural gas liquefaction facilities and other similar facilities. 

During the initial phases of design of a pipeline system, the diameter of the pipe combined with the proper wall thickness and grade of steel is determined in order to provide a safe operating environment to transport the product in such a volume that will be required for it to function in a cost effective/profitable basis.  Either in the initial phase or as additions after initial operations begin, compressors and/or pumping facilities are normally added to maintain or/and increase volumes of product.

The construction of a pipeline involves a number of operations, which combined comprise the “spread” to build the pipeline.  The operations include, clearing and grading of the right-of-way, hauling and stringing of the pipe, bending of the pipe, ditching, pipe laying/welding, coating field joints, lowering-in of pipe and backfilling, tie-in of sections, hydrostatic testing of the pipe and cleanup of the right-of-way.  In addition, other operations include road, canal, stream and river crossings, fabrication of launchers and receivers, mainline valves, and interconnects.  All of these phases move from start to finish, like a moving assembly line.

Upon completion of the “mainline” it goes into operation.  At that point, the pipeline owner will begin operations.  Continued monitoring of the system is required to maintain its integrity so that it can function for many years on profitable basis.
