Underwater suspension cluster type manifold system with flexible jumper tubes inside

Abstract

The invention relates to an underwater suspension cluster type manifold system with flexible jumper tubes inside. The underwater suspension cluster type manifold system with the flexible jumper tubesinside comprises a cluster type manifold main body, a buoy, a plurality of I-shaped channels, the flexible jumper tubes and a mooring system; the buoy is arranged on the bottom of the cluster type manifold main body; the I-shaped channels are arranged in the buoy; manifold branch tubes on a production hub seat are separately connected with the I-shaped channels; the far ends of the flexible jumpertubes are separately connected with dry type underwater Christmas trees in a plurality of deep water functional cabins fixed on the seabed by first automatic connecting-tripping devices while the near ends of the flexible jumper tubes are separately connected with the manifold branch tubes on the production hub seat; and the far end of the mooring system is fixed on the seabed while the near endof the mooring system is connected with the cluster type manifold main body through a second automatic connecting-tripping device. The problem that a traditional underwater cluster type manifold is unlikely to discard and recycle, and cannot be reused is solved, particularly, a large underwater foundation structure is avoided, costs for mounting of an underwater foundation of a traditional manifold are greatly reduced, the costs are reduced and the efficiency is improved, and a new-generation underwater collecting and delivering original concept of 'easiness in recycling and reusability' is established.

Description

technical field [0001] The invention relates to an underwater production system, in particular to an underwater suspension cluster manifold system with built-in flexible jumper pipes that can be reused without installing a large underwater infrastructure. Background technique [0002] The subsea production system has become the first choice in the development of deep water and ultra-deep water due to its advantages of avoiding the harsh offshore environment, small initial investment, and convenience for later maintenance and marginal oilfield development. The layout of the subsea production system is a key issue in the wet wellhead development mode of deepwater oil and gas fields. It plays a key decisive role in the oil and gas production, economic investment, underwater control, and safety risks of the entire deepwater oil and gas field. [0003] There are four typical layout forms of the subsea production system, namely single well tie-back, daisy-chain tie-back, template...
