Apparatus for repairing an underwater pipe

A pipe clamp for repairing an underwater pipe comprising:

• a plurality of part-cylindrical clamp portions each having a pair of longitudinal edges and a pair of end rims, said clamp portions being coupled together by hinges along adjacent pairs of said longitudinal edges, two of said longitudinal edges of said clamp portions being free longitudinal edges;
• a fastening arrangement for holding said free longitudinal edges of said clamp portions together;
• and
• projections extending transversely from respective end rims of ones of said clamp portions having said free longitudinal edges and being disposed generally adjacent said free longitudinal edges, said clamp portions being movable about said hinges towards and away from one another between an open position in which said free longitudinal edges are spaced-apart to allow placement of said pipe clamp around a pipe, and a closed position in which said free longitudinal edges are brought together around a pipe by an actuator which clasps said projections, the fastening arrangement is fastened, and said pipe clamp is held to a pipe.

A pipe clamp for repairing an underwater pipe comprising:

• first, second and third clamp portions each having a pair of spaced-apart and generally arcuate end edges and a pair of spaced-apart longitudinal edges extending transversely between the respective end edges, one of said longitudinal edges of each of said first and second clamp portions being pivotably connected to one of said longitudinal edges of said third clamp portion, and the other said longitudinal edge of each of said first and second clamp portions being a free longitudinal edge, said free longitudinal edges being movable towards one another to define a closed position of said pipe clamp wherein said pipe clamp has a cylindrical configuration for disposal about a pipe, and movable away from one another to define an open position of said pipe clamp;
• and
• a latch arrangement disposed to interconnect said free longitudinal edges of said first and second clamp portions to place said pipe clamp in said closed position, said latch arrangement including a plurality of latch members disposed adjacent one of said free longitudinal edges and a plurality of latch-engaging surfaces disposed adjacent the other of said free longitudinal edges, and a coupling which couples said plurality of latches together for movement in unison with one another, said latch members being biased in a direction towards a central axis defined by said pipe clamp to cause automatic locking engagement of said latch member with said latch-engaging surfaces when said pipe clamp is moved into said closed position.

A pipe clamp for repairing an underwater pipe comprising:

• first, second and third part-cylindrical clamp portions each having a pair of longitudinal edges and a pair of end rims oriented transversely to said longitudinal edges, each said longitudinal edges of said first claim portion being connected to an adjacent said longitudinal edge of each of said second and third clamp portions by a hinge, said longitudinal edges of said second and third clamp portions remote from first clamp portion defining respective free longitudinal edges of said second and third clamp portions, said second and third portions each including a projection extending transversely from one said end rim thereof;
• a resilient and compressible seal arrangement disposed on an inner surface of said pipe clamp;
• and
• a fastening arrangement for holding said free longitudinal edges together, said fastening arrangement including at least one latch disposed on at least one of said clamp portion and at least one latch-engaging surface disposed on another of said clamp portions, wherein said clamp portions are moveable about the respective said hinges towards and away from one another between an open position in which said free longitudinal edges are spaced-apart from one another to allow placement of said pipe clamp around a pipe, and a closed position in which said free longitudinal edges are brougth together around a pipe causing said latch to fasten to said latch-engaging surface and said pipe claim to be held to a pipe, said projections being configured for being clasped by an actuator to bring said free longitudinal edges into a closed position.
