Abstract: Disclosed are systems and methods for thermal management of subsea conduits such as jumpers that provide the ability to alternate between cooling and heat retention of production fluids within the conduit as needed depending on the phase of operation. Adjustable insulation elements are provided on the conduits so that convective heat transfer between surrounding seawater and the conduit can be allowed or reduced. A control system can activate an alarm indicating the need to adjust the insulation depending on the temperature and/or flow rate of fluids in the conduit. Conventional conduits can be retrofitted by adding adjustable insulation elements to enable thermal management.

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.

Abstract: Disclosed are systems and methods for thermal management of subsea jumpers that provide the ability to cool and/or retain heat in production fluids within the jumpers. The jumpers are provided with an annular pipe section surrounding the jumper circumferentially. The flow of a liquid cooling medium into an inlet and out an outlet of the annular pipe section can be controlled to provide cooling or heat retention as needed. A control system can be used to generate an alarm based on fluid temperature and/or fluid flow rate within the jumper indicating the need to adjust the flow of the cooling medium to manage the temperature of fluids within the jumper. Changes may be needed particularly depending on the phase of production, e.g., early life, normal operation, shut down and late life operation.
