Description
Technical field
The utility model is related to Bulk Transport liquefied gas ship design-build technical fields, and B is used for more particularly to one kind
The spatter shield and its unit module of type cargo tank.
Background technology
Liquefied natural gas（Liquid natural gas abbreviations LNG）Ship is for the ship of low-temperature transport liquefied natural gas
Only, it is to reduce the temperature to subzero 163 DEG C of liquefied natural gas to store cargo tank inside it and then carry out marine transportation.
The cargo tank of different structure type may be employed in LNG ship.According to《Bulk Transport liquid gas ship constructs and equipment
Specification》（IGC Code）Regulation, the structural shape of cargo tank mainly has two major classes：Film-type cargo tank and self liquid goods
Cabin.Film-type cargo tank is non-self-supporting formula cargo hold, is made up of adjacent Ship Structure the thin film that heat insulation layer is supported,
Specifically it is divided into as NO96 types, MARK type IIIs, CS1 types etc..Self cargo tank is self-supporting formula cargo hold, and cargo hold does not form hull
A structure part, is not required Hull Strength.Self cargo tank is specifically divided into A types cargo tank, Type B cargo tank, c-type liquid
Three kinds of cargo hold.A type cargo tanks require complete screen-wall, and Type B cargo tank only needs setting unit gradation screen-wall, and c-type liquid goods
Cabin does not require to set time screen-wall.
Independent Type B cargo tank only needs setting unit gradation screen-wall.When main screen wall leaks, part time screen-wall should be able to be prevented
Only Ship Structure temperature drops to unsafe degree, can accommodate the cargo of any estimated leakage of 15 day time, quiet in ship
Angle of Heel remains to fulfil its function when being 30 degree.In all cases, part time screen-wall should protect the inner bottom plating of neighbouring cargo tank,
To prevent influence of the liquid goods to it.Space position beyond the screen-wall scope of part time should be equipped with spatter shield, to block liquid goods simultaneously
The place between main screen wall and secondary screen-wall is enabled its flow into, Ship Structure temperature is enable to be maintained at safe degree.
When LNG ship rides the sea, the LNG in influence and cargo hold due to wave, sea wind etc. will be rocked ceaselessly,
Type B cargo tank structure is subject to Dynamic And Static Loads to act on；Simultaneously as LNG is the state of subzero 163 DEG C of ultralow temperature, LNG ship is not stopped
Liquid goods is loaded and unloaded, the structure thermal stress of Type B cargo tank changes also very greatly；In addition, material there may be in itself with welding process it is scarce
It falls into.It is cracked that these factors are likely to result in Type B cargo tank structure, when penetration of cracks cargo tank outer wall, just forms leakage.
Type B cargo tank is designed by spatter shield, part time screen-wall, heat insulation layer, even if there is small liquid goods leakage in main screen wall,
Also it can guarantee the safety of 15 days ships under limit storm sea after leaking.
