Abstract
A system for reducing buildup of solids in pipes used in underwater oil operations is disclosed. The system includes an annular pipe having an inner pipe wall and an outer pipe wall. The inner pipe wall defines an inner pipe configured to transport an oil. The outer pipe wall is displaced from the inner pipe wall. The outer pipe wall defines an outer pipe between the outer pipe wall and the inner pipe wall. The system includes an oxidizer delivery pipe having an oxidizer delivery outlet. The oxidizer delivery pipe is configured to supply an oxidizer to the outer pipe. The system further includes a fuel delivery pipe having a fuel delivery outlet. The fuel delivery pipe is configured to supply a fuel to the outer pipe. The oxidizer and the fuel release thermal energy in an exothermic reaction.
