Abstract

The invention relates to a method and a device for installing a typical underwater manifold in a swing mode. The device is characterized by comprising a No.1 installation ship and a No.2 installation ship, wherein the manifold is arranged on a deck of the No.1 installation ship; the top of the manifold is provided with four hydraulic release clamping rings; each hydraulic release clamping ring isconnected with a steel wire rope; the other ends of the four steel wire ropes are connected to the bottom of a triangular plate body with an isosceles triangular vertical section through the hydraulic release clamping rings; the top of the triangular plate body is connected with one corner of a quadrangular plate body with a quadrangular vertical section through the hydraulic release clamping rings; the other corner opposite to the corner is connected with an A-shaped crane on the No.1 installation ship through the hydraulic release clamping rings and cables; the other two corners of the quadrangular plate body are correspondingly with a hydraulic winch on the No.1 installation ship and an A-shaped crane on the No.2 installation ship through the hydraulic release clamping rings and the cables respectively; the No.1 installation ship and the No.2 installation ship are provided with an underwater robot respectively; and the underwater robots are arranged in an umbilical cable managementsystem.

Description

technical field [0001] The invention relates to an installation method and device for an underwater manifold, in particular to a swing installation method and device for a typical underwater manifold. Background technique [0002] In recent years, with the continuous development of the economy, the demand for oil and gas resources in countries around the world is increasing. In order to obtain more oil and gas resources, people have turned their attention to the deep sea. Subsea production system has been widely concerned and applied by major oil companies because of its significant technical advantages and considerable economic benefits. Installing a large subsea production system also faces some problems as the water depth increases. The traditional installation method is to use steel wire ropes to place the underwater production system underwater, but its disadvantage is that as the water depth increases, most of the tension of the steel wire ropes is consumed by its ow...
