Insulation structure of independent type cargo tank in LPG carrier

摘要

This devise is in the liquefied petroleum gas carriers with independent cargo tank type, which is installed between the hull and cargo The aim is to allow each of the relative change between the closed position and the moving parts of the hull and cargo and can provide complete insulation of the cargo space when bonaengjae preclude damage to the duration of the bonaengjae. ; This is intended to achieve the above object, around the circumference of the outer wall of the cargo hold (3) (3a) and the hull (5) of the inner wall portion (5a) supporting the load (7) with the installation and the cargo hold (3) between installing bonaengjae 17 over the insulation to form a space inside the bonaengjae 17. The load support (7) from the first steel plate (9) secured to the bottom part of the outer wall portion (3a), wood block is arranged to abut on the bottom part of the first steel plate (9), (11), The wood block 11 sliding plate 12 contacts the bottom surface portion and rotatably supporting the relative movement of the wood block 11 of the sliding plate by solidifying the fixing resin coating layer 12, 13 and , and a resin coating layer 13, a second steel plate (15) securing the. The bonaengjae 17 is installed so that both ends of the finish on the wood block 11.
