Abstract
The invention discloses a ballast-water-free ship and an operating method thereof and relates to the technical field of ship design. The ballast-water-free ship comprises a ballast tank. A communication port is formed in the bottom of the ballast tank and can make seawater flow into or out of the ballast tank. A control device is arranged on the communication port and can control the communication port to be opened or closed. According to the operating method of the ballast-water-free ship, when the ship needs ballast navigation, the communication port in the bottom of the ballast tank is opened, and the communication port is kept to be in the open state; when the ship reaches a cargo berth and needs to be loaded with cargoes, the communication port in the bottom of the ballast tank is closed, and seawater in the ballast tank is discharged through a water discharging device arranged in the ballast tank; when the ship reaches a discharging jetty and the cargoes need to be discharged, the communication port is opened, and seawater in the discharging jetty is made to enter the ballast tank. The ballast-water-free ship and the operating method thereof guarantee that biological invasion is not caused and navigation resistance is small, and the ship can be kept stable on the sea.
Description
Technical field
The present invention relates to Ship Design Technology field, particularly relate to ballast-free boats and ships and using method thereof.
Background technology
Ballast water means as controlling water that boats and ships trims, heel, drinking water, stability or stress installs additional and suspended matter thereof aboard ship.It can thus be appreciated that important effect is played in the operation of ballast water to boats and ships, but because boats and ships normal/cruise needs to carry ballast water, therefore boats and ships need ballast water treatment plant is installed, the weight of boats and ships can be caused to increase, in addition because boats and ships can berth in different places, different with the demand of ballast water when navigating by water owing to berthing, when moored, ballast water in boats and ships can be discharged outboard, owing to the species of other regions, therefore may may cause foreign term in ballast water.
For now, more well known ballast-free boats and ships theory has three kinds, is respectively the through streaming system hull (Through-Flow System Hull) of University of Michigan of U.S. R & D design, ballast-free boats and ships (NOBS) theory that Shipbuilding Research Center of Japan (SRC) proposes, TU Delft university try the single structure hull (Monomaran) made.
With regard to through streaming system hull, the design of this type is not " pure " ballast-free boats and ships, but adopts " running water " to reach ballast object.That is, under its waterline, have a pipeline network be made up of large-scale pipeline, seawater enters from bow, and stern is discharged, and forms stable flow field, and hull is open, and the seawater slowly that flows is filled with whole boat bottom all the time to replace the effect of ballast water.All the time be the seawater in local marine site due to what adopt, therefore can not cause this situation of foreign term, thus meet the relevant regulations of IMO.
NOBS theory redesigns the one of hull, mainly through adopting the design of lateral inclination hull bottom, make the position of center line darker than traditional merchant ship of the side of having, more smooth hull bottom, thus realize clean ship and also can have enough drafts when not using ballast water to avoid bow slamming and propeller racing, also fully can guarantee the safety of boats and ships under most of sea situation simultaneously.But ship also will be arranged 2 small-sized ballast tanks for subsequent use to tackle extreme sea condition.After adopting this design, hull displacement will decline to some extent, and length and width and drinking water aspect are just larger than conventional ship type when designing.
Single structure hull, the design concept of this type ship is similar with the NOBS of Japan, also to change the object that hull buoyancy reaches ballast-free.In fact or unitary construction its feature arranges an indent by position alow exactly, and the hull part also can regarded as near by hull bottom center line moves on to ship side place, both sides, from the appearance a little as catamaran, but.After adopting this type to design, boats and ships also can have darker drinking water when underloading, avoid the situations such as propeller racing, ensure that stability during navigation.
But the shortcoming of through-flow system hull is the increase in the resistance in ship's navigation, and then reduces the dynamic efficiency of boats and ships; The hull formed under NOBS theory, due to the structural strengthening with some region of hull of widening of hull, required steel are also by increase about 10%; The contact surface of single structure hull and water increases, and therefore water resistance will be comparatively large compared with conventional ship type, and oil consumption also will increase to some extent.
Summary of the invention
The object of the invention is to propose a kind of ballast-free boats and ships, prevent the generation of biotic intrusion, ship type need not be changed, the resistance of navigation can be reduced.
The object of the invention is to the method for operation proposing a kind of ballast-free boats and ships, this method of operation, the seawater that the seawater in ballast tank can be made to be always local, can not cause biotic intrusion, can also control the height of water in ballast tank.
For reaching this object, the present invention by the following technical solutions:
A kind of ballast-free boats and ships, comprise ballast tank, connected entrance is offered in the bottom of described ballast tank, and described connected entrance can make seawater flow to or flow out described ballast tank, described connected entrance is provided with control setup, and described control setup can control the opening and closing of described connected entrance.
Further technical scheme, is provided with freeing arrangement in described ballast tank.
Further technical scheme, described control setup is valve.
Further technical scheme, described valve is by automatic controlling system.
Further technical scheme, described freeing arrangement is delivery piping.
Further technical scheme, the number of described connected entrance is multiple.
A method of operation for ballast-free boats and ships, when boats and ships need sailing in ballast, opens the connected entrance bottom ballast tank, and keeps described connected entrance to be open mode always; When boats and ships arrive cargo berth, when needing loading, close the connected entrance bottom described ballast tank, utilize the freeing arrangement arranged in described ballast tank to be discharged by the seawater in described ballast tank; When boats and ships arrive discharging quay, when needing unloading, open described connected entrance, the seawater in discharging quay is entered in described ballast tank.
Further technical scheme, described connected entrance is the opening and closing by connected entrance described in Valve controlling, and described valve is by automatic controlling system.
Further technical scheme, described freeing arrangement is the delivery piping be communicated with ballast pump.
Further technical scheme, the number of described connected entrance is multiple, requires to select the number of the opening and closing of connected entrance according to the drinking water of boats and ships.
Beneficial effect of the present invention:
The ballast-free boats and ships that the present invention proposes, connected entrance is provided with bottom its ballast tank, seawater can be made to pass in and out ballast tank, can ensure that the seawater of these boats and ships in navigation process in ballast tank is all local seawater, there will not be the situation of biotic intrusion to occur, connected entrance can limit opening and closing by control setup, make when opening without the need to connected entrance, obstruction connected entrance is communicated with seawater, and integral structure is without the need to changing, the weight of boats and ships can not be increased, the resistance of navigation can also be reduced.
The method of operation of the ballast-free boats and ships that the present invention proposes, when navigating by water, arriving cargo berth, arrival discharging quay, the seawater amount in ballast tank is controlled by the opening and closing controlling connected entrance and freeing arrangement, to ensure the stability of boats and ships, seawater when can also ensure to navigate by water in ballast tank is always local seawater, can not cause biotic intrusion.
