Abstract:
1. A system for reducing buildup of solids in pipes used in underwater oil operations, comprising: an annular pipe including an inner pipe wall and an outer pipe wall; the inner pipe wall defining an inner pipe configured to transport an oil; the outer pipe wall displaced from the inner pipe wall and defining an outer pipe between the outer pipe wall and the inner pipe wall; an oxidizer delivery pipe positioned within the outer pipe and having an oxidizer delivery outlet, the oxidizer delivery pipe configured to supply an oxidizer to the outer pipe; and a fuel delivery pipe positioned within the outer pipe and having a fuel delivery outlet, the fuel delivery pipe configured to supply a fuel to the outer pipe such that the oxidizer and the fuel release thermal energy in an exothermic reaction.
