Abstract:
The present invention relates to devices for repairing hoses of umbilicals. In this context, the present invention provides a device for repairing a hose (3) of an umbilical, comprising a tubular repair body (1) and a fusible element (2) adapted to obstruct the passage of fluid through the inside of the repair body (1), wherein the repair body (1) comprises an outside diameter that matches the internal diameter of the hose (3) to be repaired. In addition, the invention further provides a method for repairing a hose (3) of an umbilical comprising the steps of: blocking a first end (31) of a hose (3) of an umbilical; inserting a device for repairing a hose (3) of an umbilical into a second end (32) of the hose (3); injecting a polymer sealant into the second end (32) of the hose (3); using upstream pressure to move the repair device as far as the region of the leak, until the repair body (1) completely covers the opening/leak site (4); flushing the polymer sealant between the internal wall of the hose (3) and the external wall of the device as far as the opening/leak site (4) in the house (3); solidifying the polymer sealant, thereby attaching the tubular repair body (1) inside the hose (3); releasing the first end (31) of the hose (3) of the umbilical; and flushing the fusible element (2) through the inside of the hose (3).
