ABSTRACT:
A method for repairing the outer layer of a submarine flexible pipe involves applying a resin mantle which is curable on contact with water to a damaged region of the outer layer of the flexible pipe. In order to do this, a sleeve of flexible material is provided having a resin mantle applied to an inner surface thereof. The sleeve is provided with a longitudinal slit and external slots on opposite sides of the slit. A tool is provided having hydraulically operated arms with claws at the ends thereof which engage in the external slots of the sleeve to move the sleeve to an open position. The sleeve is then applied in the open condition over the flexible pipe with the resin mantle in contact with the damaged region of the outer layer of the flexible pipe. Upon operating the tool, the sleeve is closed, thereby pressing the resin mantle against the damaged region of the outer layer of the flexible pipe. After the resin mantle has reached a gel point, the tool may be operated to remove the tool from the sleeve.
