Abstract
A method of delivering a concentrated quantity of sealing elements to a leak site in a vessel (1) comprises the steps of deploying a flexible body of material (4) and at least one sealing element (3) into fluid (2) flowing within the vessel upstream of the leak site whereby the body of material transports the sealing elements through the vessel to the leak site where the body of material is drawn to the leak by fluid flow created by a pressure differential at the leak site, and wherein the sealing element(s) are constrained by the body of material at the leak site such that the sealing element(s) become(s) entrained within the leak.
Claims50
A method of delivering a concentrated quantity of sealing elements to a leak site in a vessel, the method comprising:
- deploying a flexible body of material and at least one sealing element into fluid flowing within the vessel upstream of the leak site;
- the body of material transporting the sealing elements through the vessel to the leak site where the body of material is drawn to the leak by fluid flow created by a pressure differential at the leak site;
- and
- wherein the sealing element(s) are constrained by the body of material at the leak site such that the sealing element(s) become(s) entrained within the leak.
(canceled)
A sealing composition comprising a flexible body of material and at least one sealing element, the body of material being adapted to transport the sealing element(s) in a controllable and targeted manner to a leak site within a vessel and to constrain the sealing element(s) at the leak site.
