Extended cool-down time subsea choke

Abstract

A subsea choke system Includes a flow control device fluidity coupled to a subsea well and a choke coupled to the flow control device. The choke includes a choke body coupled to the flow control device. A choke funnel base having a receiving portion is coupled to at least one side of the choke body. Additionally, a choke funnel is coupled to an upper surface of the choke funnel base to form the choke. The choke is formed from a structural insulating material such that at least one of the choke funnel or the choke funnel base is formed from a structural insulating material wherein the structural insulating material is exposed directly to subsea conditions.
