  • BOP heating methods and systems and heat exchange units
    Patent number: 9447656
    Abstract: A BOP heating method includes operating a coiled tubing unit (CTU) using hydraulic fluid. The fluid is supplied from the CTU to an exchange tube and returned from the exchange tube to the CTU. The method includes transmitting heat from the fluid to an inner plate. Heat is transmitted from the inner plate to a BOP on which the inner plate is temporarily mounted. A BOP heating system includes a CTU configured to use hydraulic fluid, a supply tube configured to supply fluid from the CTU to an exchange tube, and a return tube configured to return fluid from the exchange tube to the CTU. A BOP heat exchange unit includes an outer plate and an inner plate, an exchange tube between the outer plate and the inner plate, and a heat spreading material between the exchange tube and the inner plate. The exchange unit lacks any electrical component.
