Description

Air lift device for attaching insulation panels to cargo holds of ships {air balance for insulation panel bonding device of LNGC}

The present invention relates to an air lift apparatus for attaching a cargo hold insulation panel of a ship, and more particularly, an insulation panel of a cargo hold of a cargo ship that is heavy by using an air lift device that can easily move a heavy item by a simple operation. panel (hereinafter referred to as IP panel) relates to an air lift device for attaching a cargo hold insulation panel of a ship for easily attaching it to the inclined wall surface of the hold.

In the case of transporting natural gas from the world's production area to the consumption area across the ocean, it is generally transported by ship in consideration of transportation efficiency such as transportation cost and transportation time. However, large quantities of natural gas are transported in liquid form rather than in gaseous form at one time. Therefore, the temperature in the natural gas hold should be kept below -161 ° C, the boiling point of natural gas.

As described above, in order to maintain the inside of the cargo hold at a cryogenic condition, an insulation panel (hereinafter referred to as IP) must be placed between the cargo hold and the hull, and polyurethane foam is generally used as the insulation.
