a subsea tree comprising an area susceptible to formation of hydrates when a shut-down of a well occurs; and
a trace heating blanket comprising an exterior layer and an interior layer comprising electric coils, wherein the trace heating blanket is flexible to allow the trace heating blanket to be wrapped around the area of the subsea tree susceptible to formation of hydrates, securable in position about the area via a fastener coupling a first portion of the trace heating blanket to a second portion of the trace heating blanket, and removable from the position about the area upon removal of the fastener.
