主权项 1. A subsea wellhead assembly comprising: an inner bore, at least part of which extends through a Xmas tree landed on a subsea wellhead, for conduction of produced hydrocarbons; the subsea wellhead having components exposed to heating from a warm flow of hydrocarbons produced through the inner bore; a region located in the subsea wellhead adjacent to the inner bore; wherein the subsea wellhead comprises an inlet port and an outlet port at ends of an inlet channel and an outlet channel, respectively, connected to a cooling fluid, wherein the inlet channel conducts the cooling fluid to the region and the outlet channel conducts the cooling fluid out from the region, wherein the region is suited for cooling the subsea wellhead components; and wherein the inlet channel and the outlet channel are channels other than the inner bore and without the possibility of fluid communication with the inner bore.
