    摘要: A sealing apparatus (10) suitable for use as a subsea repair clamp has a sealing membrane (12) with first and second portions (14,16) for engaging the outer surface of a pipe. Retaining members (18,20) are located in opposing relationship to each other about the sealing membrane (12) and are secured to each other by a closure member, the retaining members (18,20) retaining sealing engagement between the sealing membrane (12) and the pipe. In particular embodiments, each of the retaining members (18,20) comprises axially spaced plates (22,24) arranged generally transversely to the longitudinal axis of the sealing membrane (12).

    摘要: A pipe end-sealing tool comprises a body. A seal is mounted on the body and is adapted to apply a sealing pressure to an inner wall of a pipe end to be sealed. A lock is also mounted on the body and is adapted to engage an outer wall of the pipe end. Thus, a load applied to the pipe wall by the lock opposes the sealing pressure.

    摘要: A coupling device (10) provides a pre-tensioned coupling between a first member (12) and a second member (14). The members (12, 14) are arranged to define a sealed compartment. A piston (34) is housed within the compartment and is translated between the first member (12) and the second member (14). A first ratchet lock (68) is mounted within the second member (14) and on translation of the piston (34) the first ratchet lock (68) engages with the piston (34). A second ratchet (70) is mounted within the second member (14) and, on translation of the piston (34) into the second member (14), the piston (34) engages with the ratchet (70). The second ratchet (70) is mounted on a piston (74) and translation of the second ratchet (70) on the piston (74) applies a tensile force to the first piston (34) to tension or pre-tension the piston (34). As the ratchets (68, 70) substantially prevent reverse movement of the piston (34), the tensile force is retained.

    摘要: A method of isolating a section of pipe comprises locating a seal unit having two seal elements in a pipe via a penetration in the pipe, such as a branch or tee. The seal unit is then positioned in the pipe downstream of the penetration. The seal elements are activated using a primary activation mechanism to engage the pipe wall and then maintained in an activated condition using a secondary activation mechanism.

    摘要: An isolation tool (10) for isolating small bore pipe (P) has a spigot (12) having a proximal section (14) with diameter (D1) and a distal section (16) with smaller diameter (D2). A seal (18) is provided on the tool (10) around the smaller diameter section (16). In some embodiments, the isolation tool (10) is located through a hole (H1) in the wall of the pipe (P) and through a second hole (H2) in the opposite wall of the pipe (P), the tool (10) arranged so that when the tool is located through the second hole (H2) the seal (18) fills the bore (B) of the pipe (P) and isolates a section of the pipe (P). In other embodiments, the tool (10) may be located between severed pipe sections.
