1, safety communication and mooring plan
Two ships should be conversed and be confirmed state separately by very high frequency, according to the work procedure of appointment and emergency plan, carry out one by one, and radio installation should be essential safe type.Consider weather and navigation state, every single stepping all needs to obtain both sides' confirmation.As needs, being noted ship should be able to provide concise and to the point sketch demonstration deck to arrange clear condition, comprises the quantity of fairlead and bollard and the information such as distance of filling station.When preparing, mooring plan should consider following factor: the size of each boats and ships and difference thereof; Estimate freeboard and water displacement difference; Expection weather conditions and sea state; Provide effective mooring to lead cable etc.
2, fender setting and alongside operation,
Alongside mobile operation should be selected in as far as possible carries out daytime, except irrelevant personnel has special experience to the job manipulation of annotating night.After receiving and berthing and agree to, can start of evolution approaching.In the process of approaching, should continue to monitor weather condition, wave and tidal regime, navigable condition etc. around simultaneously.
Two main fenders at least should be set and be fixed on filling landing stage topside, the setting of inferior fender should be able to guarantee to annotate landing stage and noted between ship and have direct touching to occur without any a place.Recommend adoption diameter is about the pneumatic pattern fender of lm, and the type of inferior fender and size depend on the design on the landing stage of annotating.
3, mooring operation, referring to Fig. 2,
When being noted ship safely and smoothly after alongside, in the situation that stormy waves and current are permitted, could start according to original mooring plan operation at sea.If the LNG filling landing stage that does not configure special mooring arrangement is at the typical Mooring Arrangements of annotating barely, should comprise at least four head lines, two fore springs and two quarter springs and four stern fasts, refer to Fig. 2.
LNG filling landing stage ISP should be provided with the mooring plan of a standard, is applicable to specific place.While confirming mooring, considered that it is very important that the relative movement of boats and ships and the variation of freeboard avoid between operational period hawser to bear excessive tension force, but hawser cannot be oversize to such an extent as to relative movement that two ships are raw excessive.The mooring line of equidirectional should be used similar material.
4, connecting communication and ground fault protection
After completing alongside and mooring, for convenience of exchanging and safety control, under some clear condition, may need the wired connection of two ships.Mainly comprise warning connection, emergent stopping control box of communication connection, tank level and temperature and pressure monitoring, two ships etc.Two gears have identical connection and communication interface.Should locate to equip single Jie's insulated flange each house steward, or one section of electric discontinuous flexible pipe of every flexible pipe equipment, or special construction flexible pipe prevents current delivery between accumulation of static electricity or boats and ships.Between two ships, potential electromotive force should be down to minimum.All ship-to-ship mooring lines should insulate, or use the soft mooring rope of natural material or the every metal mooring line that soft stern fast is connected by eye thimble.Nonisulated Wire ladder between two ships or gangway ladder should be installed rubber at ladder end.Suspension rod or hoist steel wire and the operation of suspension hook care should be used to.Fender supports the standing grain in net or cage region to need high-quality to safeguard through bare wire and the chain of protection.
5, connecting hose/handling arm, referring to Fig. 3,
Before connecting hose/handling arm, should guaranteeing to shout LNG flexible hose for loading, to unload the state of arm intact, reaches expectation service condition.Arm or the employing flexible pipe bracket of by LNG, annotating on landing stage, also can install flexible pipe/handling arm by auxiliary docking facilities or the docking guide rail of advising, to reduce the impact of boats and ships being rocked due to stormy waves.The installation of flexible pipe should be considered suitable support or the problems such as friction fixing and that produce due to ship motion, selects the flexible pipe of appropriate length, and guarantee that the crooked radian of flexible pipe is up to specification according to the different height difference of the drinking water of two ships.Connecting hose is often referred to dry type rapid pipe joint (manually flange or hydraulicefficiency telecontrol operation) and connects, and is also furnished with urgent Pull breaking ualve on flexible pipe simultaneously.Ordinary circumstance bottom hose two ends are connected with ESD remote-controlled valve, mainly in case of emergency can fast shut-off charging line.After connecting hose, can carry out hot test to ESD valve member.On handling arm, are conventionally furnished with the critical components such as position monitoring system, quick connector, emergency separating device and swivel joint, landing stage, riverbank is arranged when U reads G handling arm, according to factors such as river low water water level, flood level, boats and ships range of drift, determine that the envelope vapour of liquid handling arm encloses.Position monitoring system should be reported to the police and perform an action according to handling arm swing and rotating minute two-stage.
The specific operation of described step 3 are as follows, checking table before filling; Adding amount and filling speed; Precooling internal duct and dispenser pump; Inerting and displacement; Open manual and remote-controlled valve; To two ships, send ready signal; Start dispenser pump program; Top and bottom liquid inlet be filling alternately; Stop dispenser pump program; Purging and inerting etc.
1, checking table before filling
After the firmly mooring of two boats and ships and before LNG filling starts, should guarantee to set up good communication between the filling Line Leader of each boats and ships, and successfully complete the inspection before filling.Checking table before particular content for details, see the appendix 5 filling, before formal filling, checking table should be by each ship Line Leader withdrawal of signing.Captain should guarantee to observe the security step of all recommendations in the works, and formulates emergency plan and deal with any urgency in filling process.
When preparing LNG filling plan, should consider to guarantee that boats and ships maintain enough stabilities, Structure stress maintains in design limit, and it is minimum that free surface effect remains.The plan that LNG filling operation should have two ships to agree in writing form, when feasible, before should comprising that LNG filling starts, filling landing stage should be known and noted ship at the flow of different phase.As the change of the speed of annotating is necessary, noted ship and should be informed the requirement in this respect of filling landing stage.Equally, filling is that ship should be informed and noted ship because operation and the variation of any flow of causing.Consult the filling speed of agreeing to, should not shout and unload the flow that arm manufacturer advises over flexible hose for loading.
2, landing stage filling principle
At present, the external dosing method of Marine vacuum heat insulation-type LNG storage tank mainly contains three kinds: auto-pressurizing; Dispenser pump formula; From supercharging and dispenser pump convolution.
Auto-pressurizing is that LNG in storage tank is vaporized by entering heat exchanger from supercharging concentrated phase pipe, and the gas after vaporization returns in storage tank, improves the gaseous pressure of storage tank, and oneself reaches the object of external filling.That is, the power source of auto-pressurizing storage tank is filling tank and the pressure difference of being noted tank.Advantage from supercharging dagger-axe storage tank is that technological process simply, does not need power consumption; Shortcoming is a main more emptying gas, filling time compared with two, noted tank needs continuous pressure release poor etc. to increase two pressure tanks.Dispenser pump formula is that two ear G annotate to being noted the gas-phase space of tank filling tank and the gas-phase space UNICOM of being noted tank via immersed pump supercharging, noted inflexible BOG in tank and got back to filling tank first by muffler, solved filling tank because liquid reduces the problem of pressure decreased, also solved simultaneously and noted tank and increase the problem that gaseous pressure raises because of liquid, whole filling process is without to being noted tank pressure release.The advantages such as comprehensive, good fortune note efficiency is high although dispenser pump formula has, the filling time is short, simple operation, also have line arrangement complexity, increase the rhymed formula points such as manufacture and maintenance cost.Particularly adopt deep-well pump form in tank, very high to the sealing of storage tank and pump housing joint and adiabatic requirement, the domestic ships moon storage tank not yet adopt this form, and generally adopt immersed pump outside tank.
Referring to Fig. 4, two kinds of situations should be avoided with being noted in ship power mouth main procedure in LNG filling landing stage: 1. forbid inflammable gas and air to appear at some place simultaneously; If 2. 1. there is no proud arriving, should guarantee that so this place does not have burning things which may cause a fire disaster to produce.Around this two principle, we realize LNG filling operation waterborne.The working principle of this system is: with immersed pump, LNG is transported to and is noted in ship storage tank by flexible hose for loading, for increasing engine fuel system on transporting velocity shortening filling time and filling landing stage, need, the landing stage LNG storage tank of generally annotating is also furnished with self-supercharging device.The remote control manually behaviour's emergency shut-in valve how (ESD) of holding concurrently is all housed at the two ends of flexible pipe, if occur to leak or operation exception, ESD can close by automatic or manual, for response time of preventing overvoltage ESD is about 30 seconds.When ESD closes, for preventing pressure oscillation, storage tank is equipped with self-circulation system to lower the temperature and step-down.For preventing annotating landing stage and noted relative movement excessive between ship, emergency separating device (ERC) is housed on flexible pipe, be generally urgent Pull breaking ualve.Flexible hose for loading two ends adopt dry type rapid pipe joint (Dry Discolmect Couplings, DDC) to prevent from breaking rear leakage.The place that may occur rotation or friction to connecting two ends also should arrange isolated insulation pad, prevents the generation of static.
3, inner precooling, referring to Fig. 5, before formal filling, for LNG pipeline on the landing stage that prevents from annotating with dispenser pump and flowmeter etc. are prominent is subject to domestic animal effect of stress, and produces a large amount of boil-off gas.Need to carry out LNG tank inside system pre-cooledly, open the valve member of instrument such as leading to dispenser pump, flowmeter, and open tank bottom valve member and make LNG be full of all delivery lines.Also can open if desired from supercharging series connection valve member, in order to improve tank inner pressure, accelerate transporting velocity.
4, inerting pipeline
After two plumbous flexible pipes connect, in flexible pipe, may contain a certain amount of air, according to above-mentioned filling principle, must exclude the air in charging line.In LNG filling, Nie is furnished with nitrogen storage gas cylinder or nitrogen gas generating device on ship conventionally, on filling house steward, open the ESD valve member of two ships and close valve member subsequently, nitrogen enters LNG liquid and gas house steward by arm, flexible pipe is carried out to 15min, the oxygen content that needs after purging to detect in house steward confirms to be no more than prescribed limits, otherwise should carry out 2 inertings operation, until up to specification.
5, displacement pipeline, referring to Fig. 6,
After inerting meets the demands, because house steward and flexible pipe contain a large amount of nitrogen, therefore need to it, replace by NG, on LNG filling landing stage, is conventionally furnished with compression NG gas cylinder, on filling house steward, open the ESD valve member of two ships and close valve member subsequently, NG enters LNG liquid and gas house steward and flexible pipe by arm, and nitrogen is replaced.
6, top filling, referring to Fig. 7,
After inerting and displacement all complete, just can open manually and remote-controlled valve, to two ships, send ready signal, record filling house steward is the initial reading of flowmeter above, and starts dispenser pump program.For the temperature that keeps two storage tanks quite and reduce boil-off gas, when initial filling, need to adopt small flow mode of movement to be carried out precooling cooling to noting ship storage tank.Filling landing stage LNG pass through flowmeter by immersed pump and is transported to and is noted ship tank top, is noted ship storage tank gas phase and turns back to the landing stage storage tank gas phase of annotating, the gaseous pressure balance of the amount of reaching storage tank.
7, bottom filling, referring to Fig. 8,
When the temperature of two ship storage tanks is suitable and the abundant precooling of pipeline after, the slow dosing method in top can be transformed into bottom dosing method fast, in transfer process, first slowly open and lead to valve member on the charging line of bottom, by abandoning, closing the cooling valve member of top spray.When slowly annotate in top, first open bottom filling valve member and close again bottom valve member, prevent the appearance of superpressure phenomenon.In the limited field of filling speed, start high-power dispenser pump and carry, as noted ship storage tank and occur the higher phenomenon of temperature and pressure.Can again be transformed into top dosing method and carry out precooling cooling, also can adopt bottom filling and bottom two kinds of modes of filling to hocket.
8, scavenging pipeline, referring to Fig. 9,
In filling, reach after the demand of being noted ship, that notes storage tank fills the limit (being generally 90%), according to program stopped dispenser pump work, reading after recording flowmeter filling, is also provided with flowmeter on gas phase return pipeline or conventionally according to the corresponding deduction of flat evaporator rate of operation side.Now in delivery line, be full of LNG liquid, therefore need to purge operation to liquid phase delivery line.The valve member of NG gas cylinder is opened, NG gas is purged the LNG in house steward and flexible pipe to storage tank, purge time is about 15min, and the pressure of gas cylinder should be no more than the working pressure of storage tank conventionally.
9, inerting pipeline
After two ship house stewards and flexible pipe purge, in flexible pipe, may contain a certain amount of NG, inflammable gas remains in pipeline may bring harm, therefore before removing flexible pipe, needs pipeline inerting disposal again.The operation and maintenance of system nitrogen storage gas cylinder or nitrogen gas generating device entered to LNG liquid and gas house steward by arm, its pipeline carried out to inerting disposal, so that can be dismantled flexible hose for loading after inerting.
10, filling is ended
In two ship filling operation process, there is some case of emergency, should prepare to interrupt immediately filling operation, if desired from pool.Mainly comprise following situations: alongside ship moves and reaches maximum permissible value, may cause hose strength loss or excessive deformation; Freakish weather and or sea situation; There is power failure in arbitrary ship; Main communication system between two ships goes out rose and puts barrier, and there is no suitable standby communication modes; Find that LNG leaks or breaking out of fire; There is agnogenic pressure drop in LNG system; Flexible pipe, deck, the Huo Chuan village, joint pipeline are found any leakage; Discovery may cause leaks fault or the report wound threatening; Unload output and be subject to fluence to have the notable difference of unknown cause; There is any fault in bumper system; The situation such as when any boatman rises.
While adopting the filling of handling arm, All Alerts signal should have demonstration on landing stage, and during filling, emergency stopping system can be carried out following action: 1., when 1 grade of generation is transfinited, dispenser pump stops, and emergency separating device ball valve is closed; 2. when 2 grades of generations are transfinited, dispenser pump stops, and emergency separating device ball valve is closed, and ejection escape mechanism action is realized ship ship separated.
