Description

The matched tube structure of oil tanker

Technical field

The present invention relates to a kind of oil tanker of broad sense, that is only load the special-purpose oil tanker of crude oil and be not only the high-mobility, multipurpose, wheeled vehicle oil tanker that crude oil also can load solid goods such as ore or coal, particularly its cargo oil pipe and other pipeline structures.

Background technology

Existing oil tanker is shown in Fig. 8 (a); In the pump house 16 that the front of engine chamber 18 on the quarter is provided with cargo oil pump 17 is set, Cargo Oil induction pipe 57 that is connected with each oil cargo tank and the Cargo Oil that links to each other with the ship-to-shore connection 48 that is arranged on midship UD upper deck top are seen off and are managed 50 coupled respectively connecing.In oil (crude oil) shipment, the oil of each oil groove is sucked by cargo oil pump 17 through Cargo Oil induction pipe 57, sees pipe 50 from cargo oil pump off through Cargo Oil and arrives ship-to-shore connections 48, and be transferred to land thus and accept facility.For improving suction efficiency, make Cargo Oil induction pipe 57 usually through lowest possible position in the oil cargo tank.On the other hand, it is upright from UD upper deck 30 tops from pump house that Cargo Oil is seen pipe 50 off, arrives midship with this state through the UD upper deck top.

In such pipe arrangement, the Cargo Oil of the UD upper deck top of being laid in sees that pipe 50 is exposed in wave or the sea wind off and corrosion easily needs high cost to carry out maintenance.And the bigbore Cargo Oil of the UD upper deck top of being laid in is seen left and right directions current that pipe 50 hinders the UD upper decks top off, and crewman's work efficiency is descended.

So, in the patent documentation 1 and 2, shown in Fig. 8 (b), disclose a kind of Cargo Oil of oil tanker that makes and seen pipe 50 off not through the UD upper deck top but through in the cargo oil tank and in the upright technical scheme that is connected with ship-to-shore connection 48 above the UD upper deck of starting from of midship.So, Cargo Oil is seen pipe 50 off and is disappeared from UD upper deck, does not have corrosion and hinders the current problem in top, deck.

But in the existing oil tanker, hindering the current of UD upper deck top is not only that Cargo Oil is seen pipe off.As other pipelines that above UD upper deck, lays, bunker oil filling tube, Cargo Oil Residual oil pipe, fire chief are arranged, pipe, wiring tube etc. clear the ship.In addition; Nearest mammoth tanker is for preventing explosion accident; And inert gas installation is installed, and the unreactable gas that comes from the inert gas generator guiding that is configured in afterbody is responsible for and is being laid into above the UD upper deck near the fore, and these also hinder the current of UD upper deck.

Particularly on the high-mobility, multipurpose, wheeled vehicle oil tanker that also can load ore or coke, on UD upper deck, there is hatch, so the problem of passing through in the UD upper deck top is more.And in loading and unloading ore or coal etc., ore or coal can drop on each pipe, so the cover that needs protection on each pipe exists for and removes ore, the coal slag that remains in after loading and unloading below the protective case, spend very much the problem of staff.

So, only make Cargo Oil see pipe off through in the cargo oil tank, can not fundamentally solve the problems such as current, cleaning, corrosion of piping deterioration of UD upper deck top.

The specific embodiment

At first the situation to ore/oily multi-purpose ship describes.Like Fig. 1 and shown in Figure 2, hull is divided by cross wall 10, and is continuous with the order of fore portion 12, cargo hold 14, pump house 16, engine chamber 18, quarter of a ship 20 according to this from the place ahead.Above engine chamber 18, be provided with residential development 22 and operator's compartment 24.

As shown in Figure 3, cargo hold 14 reaches shipboard alow and is dual hull construction, and its inside is ballast tank 26,28.Vertical logical next door 32 about the space quilt that these dual hull construction and UD upper deck 30 are surrounded is divided into central Cargo Oil groove (double as ore warehouse) 34 and left and right sides Cargo Oil groove 36.UD upper deck 30 directly over central Cargo Oil groove 34 is provided with hatch 38, and hatch possesses the hatch cover 40 of oil seal structure.

On the top of central cargo oil tank 34, indulge the pipe path 42 that the mode of leading between next door 32 and the hatch 38 is formed with the hermetically-sealed construction in essentially rectangular cross section to be clipped in.Surround the leg of pipe path, upside is made up of UD upper deck 30, and the outside is made up of vertical logical next door 32, and in addition, interior side enclosure wall is to utilize the hatch side girder 46 that is arranged on the UD upper deck lower surface and form.So, the pipe path utilizes

hull structure parts

32,46 double 3 faces doing leg, so can process at a low price.

Two sides of a ship at the UD upper deck back side form pipe path 42 like this, and lay the various pipelines of the existing UD upper deck top that is laid in therein.As shown in Figure 2, the pipe path of two sides of a ship all forwards extends from pump house 16, but different in port and starboard length, starboard pipe path only is roughly to arrive hull central authorities, and larboard pipe path extends near the arrival fore.

Under the situation of this ship, come out to see pipe 50 off from pump house 16 and amount to 3 towards the Cargo Oil of the ship-to-shore connection 48 of midship, as shown in Figure 3, wherein 2 through starboard pipe path, remain 1 and passes through larboard pipe path.About the ship-to-shore connection 48 of each side of a ship by communicating pipe 52 connections, see pipe 50 off above midship is led to UD upper deck through the Cargo Oil of pipe path, and link to each other with communicating pipe 52.

In addition, contain the pipeline system 54 that is connected in ship-to-shore connection 48 in the pipe path 42 astarboard, for example bunker oil filling tube or Cargo Oil Residual oil pipe etc.

This ship when cargo oil tank is negative pressure when unloading or in the navigation, can be inhaled into unreactable gas rather than extraneous air (handle the gas of main boiler waste gas gained, contain oxygen hardly) in order to prevent the explosion accident of Cargo Oil groove in the cargo tank.The pipeline of carrying unreactable gas is to see the roughly the same heavy caliber pipeline of pipe 50 off with Cargo Oil, and this inert gas tube 58 lays near fore through in the larboard pipe path.Inert gas tube 58 midway branch branched pipe 60 is arranged, as shown in Figure 4, these branched pipes arrive each

Cargo Oil groove

34,36 through UD upper deck top.

In larboard pipe path, like Fig. 3 and shown in Figure 4, except that Cargo Oil is seen pipe 50 and inert gas tube 58 off, also through the pipeline system 62 that extends to fore, for example cargo tank purge pipe, fire chief, wiring tube etc. are arranged.

Owing to carry out the operation such as switch of valve, the maintenance inspection of each pipeline etc., and a plurality of import and export 68 are set in the inside of pipe path 42, so that can debouch pipe path 42 from UD upper deck 30, import and export can be closed by watertight door.In addition, guarantee that the people can current size also be very important in pipe path 42.

In pipe path 42, drafting apparatus, gas monitor and fire extinguisher plant (for example CO2 formula) etc. preferably are set, do not cause fire accident so that can not be detained fire gases in the pipe path.

In addition, Reference numeral 57 is Cargo Oil induction pipes, lays through the bottom of left and right sides Cargo Oil groove 36 and towards pump house 16.

In the above embodiments, pipe path 42 is arranged between vertical logical next door and the hatch, but as shown in Figure 5, also can be under UD upper deck with the pipe channel setting, and join with shipboard ballast tank 28.At this moment, the outside portion of the leg of pipe path 42 is made up of the inwall 29 of shipboard ballast tank 28 respectively.Each pipeline through in the pipe path is consistent with the situation of Fig. 3.

Fig. 6 is the situation of special-purpose oil tanker.Because this ship does not have hatch, shown in dotted line among this figure, 1 pipe path 42 is set to pass the hull center, wherein contains Cargo Oil and sees pipe, inert gas tube off, reaches other pipeline systems.Perhaps, shown in this figure solid line, also can pipe path 42 be arranged to two sides of a ship symmetry with the form of joining with the dual hull construction of shipboard.

What Fig. 7 showed is the OBO ship, that is the situation of oil, coke, ore high-mobility, multipurpose, wheeled vehicle oil tanker, manages path 42 and is formed the form that is clipped between shipboard ballast tank 28 and the hatch 38.Under the situation of this ship, the width of hatch is big, so the UD upper deck of hatch sidepiece top path is very narrow, so make each pipeline not pass through the advantage highly significant of this narrow gap.
