Abstract
A subsea induction heating system (10) comprising a subsea inline heater module (14) configured for heating a subsea hydrocarbon production or processing component (7) is described. The subsea inline heater module has an induction coil (6) configured for generating a variable magnetic field in the component. The system has a subsea variable frequency drive (4) configured for energizing the induction coil to achieve a desired temperature in the component. A corresponding method is also disclosed.
Claims11
A subsea induction heating system comprising:
- a subsea inline heater module configured for heating a subsea hydrocarbon production or processing component, the subsea inline heater module comprising a modular structure which includes both an induction coil configured for generating a variable magnetic field in the component and a subsea variable frequency drive configured for energizing the induction coil to achieve a desired temperature in the component;
- wherein the subsea inline heater module is configured to be energized from a topside platform via a power umbilical extending to an umbilical termination assembly;
- and
- wherein an electrical flying lead jumper connects the umbilical termination assembly to the subsea inline heater module.
A method of heating a subsea component in a subsea hydrocarbon production or processing system, the method comprising the steps of:
- installing, on the component, a subsea inline heater module comprising a modular structure which includes both an induction coil configured for generating a variable magnetic field in the component and a subsea variable frequency drive configured for energizing the induction coil;
- providing a power umbilical from a platform to an umbilical termination assembly;
- providing an electrical flying lead connecting the umbilical termination assembly to the subsea inline heater module;
- and
- heating the component by energizing the induction coil using the subsea variable frequency drive to achieve a desired temperature in the component.
