Background

Since 1 month and 1 day 2015, the european union began to implement strict emission standards for marine sulfides, which were reduced to 0.1% for ships traveling in the exclusive control zones of the european union such as the porpoise sea, the north sea, and the english channel. This term has a large impact on freight because freight costs are sensitive to fuel price, and conventional fuel in shipping is heavy fuel, typically with a sulfur content between 1.0% and 3.5%. To meet the emission control zone requirements of 0.1% sulfur content, shipping companies must use different types of higher purity fuels and therefore are more expensive. The LNG has the advantages of high heat value and low environmental pollution, and gradually becomes the first choice of green energy, the international and domestic LNG trade and transportation are continuously increased, and the demand of LNG ships is rapidly increased. However, the storage temperature of natural gas in the LNG tank body is-163 ℃ in a real ship, the tank body is stressed by self contraction, sea surface bump and the like, and the solid supporting saddle has great influence on the strength and the service life of the tank body.

The saddle 1 consists of a fixed saddle and a sliding saddle. The fixed saddle and the sliding saddle are distributed at the two ends of the liquid tank along the length direction of the liquid tank 17.

The fixed saddle comprises a fixed saddle panel 1 and fixed pressure-bearing wood blocks 2, baffle plates 3 are welded on the left side and the right side of the fixed saddle panel 1 respectively, the fixed pressure-bearing wood blocks 2 are supported on the fixed saddle panel 1 and limited by the baffle plates 3 on the two sides, the height of the baffle plates 3 generally reaches more than half of the height of the fixed pressure-bearing wood blocks, and the fixed pressure-bearing wood blocks are prevented from overturning. Epoxy glue mud 4 is filled between the fixed pressure-bearing wood block 2 and the fixed saddle panel 1 and between the fixed pressure-bearing wood block and the corresponding baffle 3, and the epoxy glue mud 4 is used for buffering, bonding and fixing; a downward convex limiting strip 5 is welded at the center of the bottom of the liquid tank corresponding to the fixed saddle 1, the limiting strip 5 is vertical to the axis direction of the tank body, and the limiting strip 5 is embedded in a groove on the fixed pressure-bearing wood block 2; epoxy cement is filled between the limiting strip 5 and the fixed pressure-bearing wood block 2 for bonding and buffering. When the ship jolts, the fixed saddle fixes and limits the liquid tank.
