The specific embodiment
In Fig. 1, Fig. 2, a kind of liquefied gas carrier oceangoing ship, at least one storage tank is installed on the hull 16 through fixed bearing 1 and sliding feet 6;
Described storage tank is the bearing structure of multilayer, with supporting goods pump, goods compressor and the nitrogen-making device of also being provided with of storage tank.
Goods pump in this example adopts electronic deep well pump, one of each storage tank configuration.The goods compressor is the oil-free lubrication piston compressor, through the separation driving device by motor direct-drive.Nitrogen-making device is made up of screw compressor, air dryer, air cooler, steam separator, PSA assembly and control unit etc.Nitrogen gas purity: 99.9 % above (N2+Ar); Nitrogen output: 300 cubic meters/h.
With supporting goods piping and the valve member in addition of storage tank.Specifically comprise the valve member of goods piping, cargo pipe work, valve body material is selected carbon steel for use, and valve disc, stem material are used corrosion-resistant steel, and valve seat is used polytetrafluoroethylene (PTFE).Quick closing stop valve: quick closing stop valve adopts fluid control.
Also be provided with control monitor unit in the corresponding storage tank; Be used for to monitor the situation of goods running condition (as: liquid level, temperature, pressure and other parameters) at liquid goods control cabin; Integrated monitor panel through being located in the liquid goods control cabin can these parameters of long-range demonstration, and establish alarm board at operator's compartment and be used for reporting to the police.
Described hull 16 is the structure of raked stem cornice ball bow, square stern.Bulbous bow can reduce the wave making resistance of boats and ships effectively, and the water resistance of water of meeting offsets in wave energy that a upset of its generation is 180 ° and the navigation; The afterbody buttock line grading of square stern is bordering on straight line, thereby current are roughly flowed along the buttock line direction, reduces reversing and degree of crook of high-velocity flow; Thereby the minimizing capacity loss improves resistance performance, the more important thing is that high-velocity flow extends to behind the tail quite distance always along the square tail edge; Be equivalent to increase the effective length of hull; Thereby help reducing residuary resistance, in addition because the afterbody displacement of volume of square tail is bigger, can reduce in the underway the tail phenomenon of inclining.This structure has promoted the stability of hull, rapidity effectively.Satisfy CMSA boats and ships and Offshore Units statutory formula rule-international voyage Technical Regulation for Statutory Survey of Seagoing Ships " requirement of (2008); Damaged stability satisfies the relevant requirements of CCS " conveying liquified gas construction of vessel in bulk and equipment specifications " (2005).The structure that cooperates the utility model bilge keel, and through optimizing the line style design, more a step is improved this ship rough water quality, fast and stable property.
Described hull 16 is unit, single-blade, single rudder stern type.Machine, oar, the rudder three coordinating and unifying make stablely more in the ship's navigation process, flexibly, more are applicable to ocean freight, and have very big advantage at aspects such as the course change of boats and ships, permanent revolution, reversings.At aspects such as economy, power consumption, environmental protection, more thrifty more economically than homogeneous structure boats and ships.
Described hull 16 is the two sides of a ship of all steel matter, Double bottom full voltage type structure.
