Sealing device for a tubing arrangement

A method of sealing a tubing arrangement having a cable or an inner tube arranged in an interior part thereof, comprising:

• providing a sealing device having a substantially rigid housing having a continuous side wall and a pair of opposed annular end walls, said side wall and said pair of opposed annular end walls defining said housing as being substantially cylindrical, and said housing comprising at least two detachable housing parts and having an interior part that communicates with the tubing arrangement to define a substantially cylindrical enclosed space between an inner surface of said side wall of the housing and an outer surface of the cable or inner tube and between inner surfaces of said opposed annular end walls of said housing, and the sealing device further having a flexible plug part arranged in and contained within said space and having at least two detachable plug portions, the detachable housing parts and the detachable plug portions detachable from each other in a manner which allows removal of the flexible plug part,
• mounting the sealing device on the tubing arrangement, and
• supplying grout material to the flexible plug part of the sealing device such that the flexible plug part expands within the space to create a first seal between said inner surface of said side wall of said housing and the flexible plug part for the length of said first seal, and a second seal between the flexible plug part and the outer surface of the cable or inner tube for the length of said second seal, wherein said cable or inner tube is stationary relative to said flexible plug part.

A method of repairing or replacing a tubing arrangement including a cable or inner tube, the tubing arrangement further including a substantially rigid housing having a continuous side wall and a pair of opposed annular end walls, said side wall and said pair of opposed annular end walls defining said housing as being substantially cylindrical, and said housing comprising at least two detachable housing parts, the housing and the cable or inner tube defining a substantially cylindrical enclosed space between an inner surface of the side wall of the housing and an outer surface of the cable or inner tube and between inner surfaces of the opposed annular end walls of the housing, and the tubing arrangement further including a flexible plug part arranged in and contained within the space and having at least two detachable plug portions, the method comprising:

• detaching at least two housing parts of the housing of the tubing arrangement;
• removing at least one of the at least two housing parts from the tubing arrangement;
• detaching at least two plug portions of the flexible plug part;
• removing the flexible plug part from the housing;
• inserting another flexible plug part into the housing, the another flexible plug part having at least two plug portions;
• replacing the at least one of the at least two housing parts previously removed from the housing;
• and
• filling the another flexible plug part with grout material to create a first seal between the inner surface of said side wall of the housing and the flexible plug part for the length of the first seal, and a second seal between the flexible plug part and the outer surface of the cable or inner tube for the length of the second seal;
• wherein said cable or inner tube is stationary relative to said flexible plug part.
