Abstract

The invention relates to an installation auxiliary device for a deep-sea fixed functional cabin, which includes an upper auxiliary module and a lower auxiliary module arranged oppositely, the upper auxiliary module is installed above the lower auxiliary module through a plurality of counterweight struts, and includes a horizontal arrangement The ring bracket is installed under the upper auxiliary module through the dry root bracket brace. In the present invention, by setting the upper auxiliary module and the lower auxiliary module, the fixed deep-water working cabin is subjected to negative buoyancy and sinks, and can withstand the deep-water high-pressure environment without deformation and crushing. It has a certain installation flexibility, and different supporting plate structures are set on the ring bracket for different pressure shells to meet the tight limit requirements of various pressure shells; all hydraulic pushing mechanisms are connected to the same accumulator, which can Fast synchronous control is realized, and a return spring is installed to prevent the ring bracket from interfering with the process of detaching from the fixed deep-sea functional cabin of the present invention.

Description

technical field [0001] The invention relates to the technical field of functional cabin installation equipment, in particular to an installation auxiliary device for deep-sea fixed functional cabins. Background technique [0002] The fixed deep-water functional cabin is a pressure-resistant structure used in seawater environments with a depth of more than 1,000 meters, and is equipped with underwater production equipment such as underwater wellhead devices, blowout preventers, and oil-water separators. When the fixed deep-water functional cabin is in use, the outside is a high-pressure seawater environment, and the inside is a normal-pressure dry environment. The main structure of the fixed deep-water functional cabin has two characteristics: one is resistant to deep-sea high pressure, and maintains structural integrity in the deep-sea environment without yielding or crushing; the other is to isolate the external seawater from the internal equipment and provide normal pressu...
