METHOD AND DEVICE FOR INTERCONNECTION OF TWO PIPES ON A SEABED

摘要

A method for connection of a first, stationary pipe (21) with a second, movable pipe on a seabed (20). The first pipe (21) is initially enclosed with clearance by a first sleeve (6) of a rigid frame (1). The second pipe is pulled into the frame (1) and enclosed by a second sleeve (7) of the frame (1). From each sleeve (6, 7) there protrudes a pipe connection. The pipe connections are interconnected via an interconnecting pipe. Between each sleeve inside the pipe connections and the pipes (21) connected thereto, a gasket is mounted. The gasket is clamped between the sleeves and the pipes by means of jacks. A perforating device finally provides holes through each sleeve (6, 7) and the wall of the associated pipe (21), whereby a communication is obtained between the pipes via the pipe connections and the interconnecting pipe. A device for implementing the method and a device for sealing connection of a sleeve with a pipe.
