Systems and methods for temperature tracking and detection of leaks
A method of detecting a leak in a production, drilling, or export system including a control system including at least one temperature transmitter. The method includes detecting the operating temperature of production fluid. The method also includes activating a temperature tracking system if the operating temperature of the production fluid exceeds a minimum temperature threshold. The method further includes determining if the operating temperature has reached a steady state operating temperature for a predetermined stability period. The method also includes arming the temperature tracking system by determining a temperature zone that extends above and below the steady state operating temperature of the production fluid. The method further includes continuously determining if the operating temperature is within the temperature zone. The method also includes indicating to an operator a potential of a leak in the production, drilling, or export system if the operating temperature deviates from the temperature zone.
