During the reconstruction of the gas pipelines or the connection of a new branch of the gas pipeline to the existing system, gas from the existing or reconstructed section of the pipeline, when pressure falls in the system, must be discharged into the atmosphere, as there is currently no other way of removing gas from the system. Emissions into the atmosphere cause irreparable damage to the environment. The transmission system operator incurs costs each year as the loss of natural gas needs to be re-acquired and there is a risk of heavy fines for methane emissions in the future. In order to ensure the safe and reliable operation of the natural gas transmission system and to reduce emissions into the environment, in the public interest and for the benefit of consumers, it is necessary to purchase natural gas pumping equipment. One of the most reliable and advanced means of pumping gas from one section of the pipeline to another is a mobile gas compressor. A mobile natural gas compressor would effectively operate the gas transmission system, create flexibility to manage gas flows and reduce emissions into the atmosphere.
