Abstract: Systems and methods comprise structures and methods for using a plurality of chemicals which are mixed subsea, resulting in a heated fluid which can be delivered by various means to an area about a subsea structure such as a pipe or other structure which has been compromised by a plug such as a solid gas hydrate or paraffinic plug. Various embodiments allow for selective use of insulated chambers and baffled conduits and the like, or combinations thereof, to aid in the mixing of the various chemicals and achieving a desired temperature.

Abstract: The operating performance and reliability of a pump, e.g. a hydraulic pump, can be significantly improved by incorporating an actively controlled positive displacement control valve in fluid communication with a fixed displacement pump, supply fluid line, and return fluid line. In use, the pump may be used to move fluid from the suction side to the discharge side of the pump, including fully opening the suction circuit to the pump cylinder and fully closing the pump discharge circuit during a pump suction stroke, fully closing the suction circuit and fully opening the pump discharge circuit to a downstream circuit during a pump discharge stroke, and allowing fluid to be pumped without the fluid passing through a valve spring loaded check valve.
