Two-way slidable anti-settling plate foundation structure of submarine manifold system

Abstract

The invention discloses a two-way slidable anti-settling plate foundation structure of a submarine manifold system. The two-way slidable anti-settling plate foundation structure comprises an anti-settling plate foundation and a two-way sliding structure; the two-way sliding structure is composed of lower-layer rails, upper-layer rails and sliding shoes; the lower-layer rails and the upper-layer rails are fixed on the anti-setting plate foundation, and the sliding shoes are connected with the lower-layer rails and the upper-layer rails; the upper-layer rails installed on the lower-layer rails can slide along the lower-layer rails; the sliding shoes of the upper-layer rails are arranged on upper flanges of I-shaped structures of the two upper-layer rails in a clamped and sleeved mode through clamping grooves formed in the front sides and the rear sides of the sliding shoes of the upper-layer rails respectively; a manifold system is installed on the top walls of the sliding shoes of the upper-layer rails; and a submarine pipeline is mounted on the manifold system. Through the structure, the manifold can freely slide in two directions under the horizontal acting force, and horizontal thrust caused by thermal expansion and cold contraction deformation of a pipeline is eliminated.

Description

technical field [0001] The invention relates to an anti-sinking plate foundation structure, in particular to a two-way slidable anti-sinking plate foundation structure of a submarine manifold system. Background technique [0002] The subsea anti-settling plate foundation is used to support various underwater production systems, such as underwater wellheads, manifold nodes, manifold terminals, etc., and is the preferred foundation form for deep-sea resource development. The traditional subsea manifold terminal is fixed on the foundation of the subsea anti-sinking plate, and the manifold terminal is connected to the oil pipeline. Because the oil transportation temperature is 90°C, the working temperature of the oil pipeline when transporting oil is 90°C. When the oil pipeline is shut down, the temperature of the oil pipeline will drop to about 4°C. , so the foundation of the anti-settling plate will be subject to enormous horizontal force and bending moment force. In order to...
