Liquefied gas ship tank insulation system
Patent
·
OSTI ID:6924124
Chicago Bridge and Iron Co. has developed an improved system for insulating a free-standing cargo tank of spherical or other shape. Nongranular insulation is secured to the ship-hold walls and hold bottom; a ship-hold cover extends over the tank-top portion and is joined to the ship; and a layer of loose-fill insulation plus a resilient blanket layer extends between the tank-top portion and the ship-hold cover. The insulating system is particularly useful when the tank-top portion extends partially above the ship deck and also when both it and the ship-hold cover are domed. A splash shield separates the tank-top portion from the loose-fill insulation so that in case of a leak in the tank shell, the escaping liquid or vapor will be prevented from penetrating the loose-fill insulation and cooling the adjacent portion of the ship-hold cover or hold wall.
