DISCONNECTION METHOD OF DEVICE FOR TRANSFER OF FLUID MEDIUM BETWEEN BOTTOM OF WATER SPACE AND SURFACE, AND CORRESPONDING TRANSFER DEVICE Russian patent published in 2014 - IPC E21B43/01 E21B17/02 E21B19/22 

Abstract RU 2510453 C2

FIELD: oil and gas industry.

SUBSTANCE: device includes pipeline (24) for transfer of fluid medium, tower (16), floating barge (18) installed so that it can be turned around tower (16) about rotation axis (A-A'). Pipeline (24) includes section (150) of a hose, which is wound about rotation axis (A-A') and retained with intermediate structure (20) installed between tower (16) and barge (18) between a configuration of joint rotation together with barge (18) about the rotation axis and a configuration of retention with tower (16) during rotation about rotation axis (A-A'). At the stage of connection of pipeline (24) intermediate structure (20) is installed into one of the configuration of rotation or retention; with that, the disconnection stage of pipeline (24) includes a transition piece of intermediate structure (20) to the other configuration of either rotation or retention.

EFFECT: quick and reliable disconnection so that quick repeated connection of a transfer pipeline is provided.
