Insulation system for floating marine structure

a technology for insulating systems and floating structures, which is applied in the direction of hull parts, vessel construction, transportation and packaging, etc., can solve the problems of sudden decrease in steel temperature between cold lng storage tanks, damage to cofferdams, and brittle fractures, so as to reduce the boil-off rate (bor) generated, reduce the heat transfer, and reduce the effect of heat transfer

Abstract

Disclosed herein is a heat insulating system of a floating structure, and more particularly, a heat insulating system of a floating structure in which a heat insulating material is provided at at least one of a ballast tank, a trunk deck space, and a side passage way contacting the trunk deck to decrease a boil-off rate (BOR) occurring due to a heat transfer from an external region of a hull into an LNG storage tank.

Description

TECHNICAL FIELD

[0001] The present invention relates to a heat insulating system of a floating structure, and more particularly, to a heat insulating system of a floating structure capable of decreasing a boil-off rate (BOR) by decreasing a heat transfer through at least one of a ballast tank, a trunk deck space, and a side passage way contacting a trunk deck.BACKGROUND ART

[0002] Generally, natural gas is transported in a gas state through a ground or maritime gas pipe and is stored in an LNG carrier in a liquefied natural gas (hereinafter, referred to as ‘LNG’) state to be transported to remote consumption sites.

[0003] The LNG obtained by cooling the natural gas at a very low temperature (approximately, −163° C.) has a volume decreased to approximately 1 / 600 compared to that of the natural gas in a gas state. Therefore, the LNG is very suitable for long distance transportation through the sea.

[0004] The LNG may be transported through the sea while being carried in the LNG carrier to be ...
