THERMALLY INSULATED VERTICAL SUBSEA CONNECTION SYSTEM

摘要

A vertical connection system for subsea connection of a first tubular member (2) to a second tubular member (3), the system comprising: a lower coupling member (10) comprising an upright casing (12) which encloses a liquid- filled space (13), wherein a hub (4) of the first tubular member is fixed to the casing at an upper end thereof and the first tubular member extends through said space; and an upper coupling member (20), which comprises a guide frame (21) configured to slidingly receive said casing when the upper coupling member is lowered downwards onto the lower coupling member, wherein a hub (5) of the second tubular member is fixed to the upper coupling member. The guide frame is provided with a layer (25) of thermally insulating material on its outside. The liquid- filled space is delimited downwards by a bottom wall (14) formed by thermally insulating material or covered by a layer of thermally insulating material.
