Abstract
An apparatus includes a subsea flow line and a two stage heat exchanger. The subsea flow line communicates a process flow that is associated with a subsea well, and the heat exchanger transfers thermal energy between the process flow and an ambient sea. The heat exchanger includes a primary circuit in communication with the flow line to transfer thermal energy with the process flow; and the heat exchanger includes a secondary circuit in thermal communication with the primary circuit to transfer thermal energy with the primary circuit.
