Abstract
The utility model relates to a double bottom structure of liquefied natural gas ship, including hull shell (1) and infrabasal plate (2), the stern is close to the regional middle part that cabin front end wall (11) and bow are close to middle cargo hold, is connected with side girder (3) at the bottom of the water -tight boat between hull shell (1) and infrabasal plate (2), other girder, hull shell and inner bottom hoarding become the ballast tank at the bottom of the water -tight boat, hull shell internal stability water receiving ceiling (4), non - watertight swash plate (5) that the side rigid coupling of horizontal roof slopes downwards, the bottom of non - watertight swash plate is towards one side of hull shell rigid coupling band steel (6), stern, bow other regions except that above -mentioned region are being provided with watertight swash plate (9) near topside department. Adopt the utility model discloses a structure, swash plate greatly reduced is sealed in the whole cancellations of amplitude that hull hogging moment of flexure increases, is favorable to controlling light ship weight's increase, and the oil consumption obtains control, has realized energy -concerving and environment -protectively.
Description
Technical field
The utility model relates to a kind of Ship Structure, specifically refers to, the double bottom structure of a kind of LNG carrier.
Background technology
Existing middle-size and small-size LNG carrier cargo hold is arranged and is all used c-type independent cargo hold, the double bottom structure of whole cargo area is as bulk freighter, divide close to midship is the double-decker parallel with outer bottom, there is a watertight swash plate near topside part, angle 45 degree with inner bottom plating, and intersect with outside plate, form the double bottom structure closed.Its advantage is that structure is continuous, easy construction.Double bottom is as ballast tank, and regulation ballast amount is big, advantageously reduces hoggingmoment, reduces Ship Structure stress.But after maximizing in c-type cabin, cargo hold shrinks due to line style from beginning to end, if double bottom structure remains in that this kind of version, will restrict the volume in c-type cabin.If cancelled swash plate structure, double bottom extends directly into outside plate, although c-type nacelle is long-pending to be added, but ballast water decrement is bigger, and hull hoggingmoment increase is relatively big, is unfavorable for controlling light weight, adds oil consumption, be unfavorable for energy-conserving and environment-protective.
Utility model content
Technical problem to be solved in the utility model is to provide the double bottom structure of a kind of LNG carrier, when the volume of compartment in c-type cabin increases, will not reduce ballast water capacity.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is as follows:
A kind of double bottom structure of LNG carrier, including ship outer casing and inner bottom plating, it is characterised in that:
Afterpeak is connected with side girder at the bottom of water-tight boat near the region of cabin front bulkhead and bow cargo hold in the middle part of the region of central cargo compartment between ship outer casing and inner bottom plating, side girder at the bottom of described water-tight boat surrounds ballast tank with ship outer casing and inner bottom plating, along the affixed horizontal top of hull length direction in ship outer casing, the affixed non-watertight swash plate tilting downwards of the side of described horizontal top, the bottom of described non-watertight swash plate is towards the affixed band steel in side of ship outer casing
Described afterpeak, bow cargo hold other regions in addition to above-mentioned zone are being provided with watertight swash plate at topside.
Further, the width of described horizontal top is 100cm, and the angle between horizontal top and non-watertight swash plate is 130 °.
Described band steel is vertically welded in the lower end of non-watertight swash plate, and the width of band steel is 20cm.
Compared with prior art, the beneficial effects of the utility model are:
Bow cargo hold uses existing sealing swash plate to form, with ship outer casing, the double bottom structure closed near the region of Collision Bulkhead, and bow cargo hold uses structure of the present utility model near the middle part in central cargo compartment region；Afterpeak uses structure of the present utility model near the region of cabin front bulkhead, part near central cargo compartment uses existing sealing swash plate double-decker, the scheme that the amplitude that hull hoggingmoment increases more all cancels the double bottom side ballast tank sealing swash plate is greatly lowered, be conducive to controlling the increase of light weight, oil consumption is controlled, it is achieved that energy-conserving and environment-protective.

Detailed description of the invention
With embodiment, the utility model is described in further detail below in conjunction with the accompanying drawings; the not restriction to utility model protection scope of described embodiment; obviously; those of ordinary skill in the art obtain other embodiments on the premise of being not required to pay creative work, and these broadly fall into protection domain of the present utility model.
nullIn conjunction with shown in Fig. 1 to Fig. 3，A kind of double bottom structure of LNG carrier，Including ship outer casing 1、Inner bottom plating 2 and c-type cargo tank 17，Stern is near the region of cabin front bulkhead 11、And bow is in the middle part of the region of central cargo compartment，Cancel existing wing tank watertight swash plate，It is connected with side girder 3 at the bottom of water-tight boat between ship outer casing 1 and inner bottom plating 2，Form watertight circumference，Side girder at the bottom of water-tight boat surrounds ballast tank with ship outer casing and inner bottom plating，Along the affixed horizontal top of hull length direction 4 in ship outer casing，The affixed non-watertight swash plate 5 tilting downwards of the side of described horizontal top，The width of described horizontal top is 100cm，Angle between horizontal top and non-watertight swash plate is the affixed band steel in side 6 of the bottom of 130 ° of described non-watertight swash plates towards ship outer casing，Described band steel is vertically welded in the lower end of non-watertight swash plate，The width of band steel is 20cm.Described stern, bow other regions in addition to above-mentioned zone use existing structure, are being provided with watertight swash plate 9 at topside.
Bow cargo hold uses existing sealing swash plate to form, with ship outer casing, the double bottom structure closed near the region of Collision Bulkhead, and bow cargo hold uses structure of the present utility model near the middle part in central cargo compartment region；Afterpeak uses structure of the present utility model near the region of cabin front bulkhead, part near central cargo compartment uses existing sealing swash plate double-decker, the scheme that the amplitude that hull hoggingmoment increases more all cancels the double bottom side ballast tank sealing swash plate is greatly lowered, be conducive to controlling the increase of light weight, oil consumption is controlled, it is achieved that energy-conserving and environment-protective.
