FIELD: oil and gas industry.
SUBSTANCE: in a restoration method of projected height of a fixed support of an oil line, which consists in vertical movement of a pipeline axis relative to load-carrying structures of a fixed support, according to the invention, there installed are hydraulic jacks under axes of the support on racks. Then, stop screws are set to upper position; a free travel of jacks by means of which a support spool is lifted to the distance corresponding to the design position is chosen; height adjustment is performed in the range of -200 to +200 mm. After that, adjustment plates are installed on replaceable supports in the required amount; the support spool is lowered on adjustment plates with jacks; axes of the support are fixed with stop screws; jacks are removed.
EFFECT: providing adjustment of the support height during operation and improving convenience and safety of installation.
