13. A method for thermal management of a subsea conduit that carries oil and/or gas produced from a subsea well in a subsea production facility located on a seabed, comprising:
a. providing at least one adjustable insulation element surrounding a conduit for carrying production fluids having two ends for connecting to subsea components;
b. transmitting oil and/or gas produced from the subsea well through the conduit;
c. adjusting the at least one adjustable insulation element between at least a first position wherein the conduit is relatively less insulated with respect to seawater surrounding the conduit and a second position wherein the conduit is relatively more insulated with respect to the seawater such that heat transfer between the conduit and the seawater is controlled; and
d. monitoring an internal fluid temperature of a fluid in the conduit and/or monitoring an internal fluid flow velocity of a fluid in the conduit and transmitting temperature and/or flow rate data to a processor of a control system set to automatically activate an alarm indicating a need to adjust a position of the at least one adjustable insulation element based on a predetermined fluid temperature and/or flow rate.
