PIPELINE BALLASTING METHOD Russian patent published in 2018 - IPC F16L1/06 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the oil and gas pipeline transport, and can be used for the constructed or repaired underground pipelines ballasting, including under the trench flooding conditions. Pipeline ballasting method includes the ballasting weights placement on equipped with load-bearing belts pipeline. Load-bearing belts are equipped with turning assemblies and connecting assemblies. Lowering the ballasting weight from above on the load-bearing belt, fixing on the load-bearing belt by means of connecting assembly, moving the ballasting weight around the pipeline axis to the position below the pipeline by means of the turning assembly.

EFFECT: increase in the pipeline reliability as a result of reduction of the ballasting weights propensity to overturn due to the low center of gravity, and also in the ballasting weights installation technology simplification.
