Abstract
System for loading and unloading of cold media, for example LNG or LPG, to or from a vessel, through pipes (1) connected with ball joints, where the pipes are insulated, and when each ball joint's inside part (4) has an inside pipe (3) which is sealed against the inside part (4) substantially over the letter extent, and which thereby forms an inside annulus (6) which can be evacuated, and that each ball joint's outside part (10) is surrounded by an outside annulus (9) which also may be evacuated.
Claims2
A ball joint coupling apparatus for loading and unloading of cold liquid gas media to or from a vessel through pipes (1) connected with said ball joint coupling apparatus, where the pipes are insulated, characterized in that said ball joint coupling apparatus has an inside pipe (3) and an inside part (4), said inside part (4) surrounding said inside pipe (3), said inside pipe (3) being sealed against the inside part (4) substantially over the extent of the inside part (4), thereby forming an inside annulus (6), said inside annulus (6) being evacuated, and in that said ball joint coupling apparatus has an outside part (10), said outside part (10) being surrounded by an outside annulus (9), said outside annulus (9) also being evacuated.
