FIELD: oil and gas industry.
SUBSTANCE: group of inventions refers to oil and gas industry, particularly to installation of technological assemblies on the sea bottom. The method consists in lowering the technological assembly, in introducing its first end into a receiving device, when a lower end is temporary formed out of the said first end, in maintaining the first end in the receiving device, and in lowering the second end of the technological assembly bringing the end into a horizontal position from a vertical on the sea bottom or on a module foundation. The first end of the assembly is left supported with the receiving device; a rotation axis is formed for the first end. The group of inventions also includes the method of retrieval of the assembly from the sea bottom and the receiving device for assembly handling and its implementation.
EFFECT: increased efficiency of installation-retrieval operation and of process of blow-out and cleaning of technological assembly.
