An underwater suspension cluster manifold system

Abstract

The invention relates to a submerged floating cluster manifold system which comprises a cluster manifold body, and is characterized by further comprising buoys, deep water functional modules, an underwater flexible cross-under pipe and a mooring system, wherein the plurality of buoys are arranged at the bottom of the cluster manifold body, so that the cluster manifold body is suspended underwater;the plurality of deep water functional modules are fixed at seabed; one end of the underwater flexible cross-under pipe is connected with a dry underwater Christmas tree in each deep water functionalmodules, and the other end of the underwater flexible cross-under pipe is connected with a production hub on the cluster manifold body so as to form a production loop; one end of the mooring system is fixed at the seabed, and the other end of the mooring system is connected with the cluster manifold body, so that the cluster manifold body is stably suspended in water. According to the submerged floating cluster manifold system disclosed by the invention, the problem that the traditional submerged cluster manifold is difficult in waste recovery and cannot be repeatedly utilized is solved, particularly use of a large underwater infrastructure is avoided, the cost of underwater foundation installation of the traditional manifold is greatly reduced, cost decreasing and benefit increasing effects are achieved, and the original concept of an 'easy to recover and recyclable' new-generation underwater gathering line is created.

Description

technical field [0001] The invention relates to an underwater production system equipment, in particular to a reusable underwater suspension cluster manifold system that does not need to install a large underwater infrastructure. Background technique [0002] The subsea production system has obvious advantages in the development of deep water oil and gas fields, and has been widely used in the field of deep water oil and gas development. As an important part of the underwater production system, the subsea manifold is a large metal structural equipment in the underwater production facility, mainly composed of pipelines and valves, and plays a key role in the development of deepwater oil and gas fields. Subsea manifolds mainly provide gathering points and distribution points for oil well output, water injection, gas injection, chemical injection, etc., which can greatly optimize the layout of subsea production facilities and reduce the number of pipelines used, thereby effecti...
