Abstract: Disclosed are systems and methods for thermal management of subsea interconnecting conduit such as jumpers that provide cooling and heat retention of production fluids within the jumpers. In a jumper circuit, parallel sections of jumper are provided having differing amounts of heat transfer between surrounding seawater and production fluids flowing within. Valving is provided to control fluid flow between the parallel sections of jumper, thus controlling the amount of heat transfer between the surrounding seawater and the jumper circuit. A control system can be used to generate an alarm based on fluid temperature and/or fluid flow rate within the jumper circuit indicating the need to adjust the valving to manage the temperature of fluids within the jumper circuit. Changes may be needed particularly depending on the phase of production, e.g., early life, normal operation, shut down and late life operation.
