Problems solved by technology

[0003] Different types of pipelines may need to pass through different compartments in the layout, and these perforation positions often cannot guarantee watertightness requirements
Once it is connected due to perforation, the damage stability will be reduced, and sometimes it cannot even meet the specification requirements

Embodiment Construction

[0021] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so as to better understand the purpose, features and advantages of the present invention. It should be understood that the embodiments shown in the drawings are not intended to limit the scope of the present invention, but only to illustrate the essence of the technical solutions of the present invention.

[0022] Such as figure 1 As shown, a watertight isolation structure for pipelines passing through a watertight bulkhead provided in this embodiment includes: a watertight isolation compartment body 1 with no upper and lower covers and a hollow interior, and the watertight isolation compartment body 1 is sleeved in the first watertight compartment. The exterior of the pipeline 4 between the cabin 2 and the second watertight cabin 3; the two ends of the watertight cofferdam body 1 are connected watertightly to the watertight bulkheads of the firs...

Abstract

The invention discloses a watertight isolation structure used for a pipeline to penetrating through watertight bulkheads. The watertight isolation structure is characterized in that the watertight isolation structure comprises a watertight isolation cabin with no cover up and down, the watertight isolation cabin is hollow inside, and the pipeline located between a first watertight compartment anda second watertight compartment is sleeved with the watertight isolation cabin; and the two ends of the watertight isolation cabin are in watertight connection with the watertight bulkheads of the first watertight compartment and the second watertight compartment. The problem that the bulkhead watertightness of the watertight compartments is destroyed when the pipeline penetrates through the watertight compartments is solved, watertight isolation between the different watertight compartments is guaranteed, and project investment is reduced.

Description

technical field [0001] The invention relates to a watertight isolation structure for a pipeline passing through a watertight bulkhead, belonging to the field of marine engineering. Background technique [0002] In recent years, as my country's development of offshore oil and gas fields gradually develops from shallow water to deep water, various forms of floating drilling and production platforms and production platforms have begun to be designed and used more and more. At present, many FPSO and semi-submersible drilling platforms have been put into use in the Bohai Sea and the South my country Sea. The internal structure design of various floating platforms often causes watertight isolation damage to the watertight bulkhead structure due to the crossing of pipelines with different functions such as discharge system pipelines or liquid cargo system pipelines. For example, when the discharge system shaft is arranged Holes need to be drilled in horizontal watertight bulkheads...
