LIQUID PRODUCT LONG-RANGE TRANSPORTATION SYSTEM Russian patent published in 2018 - IPC F17D1/14 

FIELD: transportation.

SUBSTANCE: invention relates to pipeline transport. Liquid product transporting system over long distances consists of a main pipeline, supply pipelines, pumping stations, a final point for receiving the pumped product from the main pipeline, line facilities of the main pipeline, includes sections of the main pipeline with a constantly increasing diameter for gas expansion directly in the pipeline. Pumping stations are installed on the main pipeline main facilities. Main pipeline offshore sections are made of polypropylene and placed in an aqueous medium by means of anchor devices equipped with a breaker. Near-shore and moorland main pipeline sections are arranged on pontoons provided with stabilizer. Intermediate pumping stations are located at geographical points, according to decrease in the difference in sea level altitudes between two geographical points, from the initial to the end point of the main pipeline section, at that, the diameter of the forming each cascade main pipeline decreases by 10 % of the main pipeline diameter located at the geographical point with the highest sea level. At the point of the main pipeline exit ashore, the main pipeline is placed into an inclined reinforced concrete shaft. Head pumping station reservoir is connected to a system of water collecting channels, made of clay or stone.

EFFECT: reduction of labor costs through simplification of the main pipeline construction.
