Description
Technical field
A kind of bulk freighter of ultra-shallow draft depth of this disclosure (super shallow draft bulk
carrier)(“SSD-BC”)。
Background technology
The bulk goods such as ore, construction material and agricultural product are usually transported by marine ship such as bulk freighter.Use bulk goods
The many restrictions factor of the such cargo of Ship Transportation includes but is not limited to that the deadweight tonnage (DWT) of bulk freighter, deadweight tonnage are eaten
The berth allocation problem of water depth (draft) and loading and discharging ports.It is essential that the draft of deadweight tonnage must not exceed correlation
Maximum permissible draft depth as defined in the port office of loading and discharging ports.When the available draft amount depth of loading ports and port of discharge not
Meanwhile to make it possible the direct transport between loading ports and port of discharge, miscellaneous solution may be taken
Scheme.It is possible, firstly, to which the loading capacity of bulk freighter is limited in DWT hereinafter, to ensure that the draft of ship is adapted to absorb water
The most shallow harbour of depth.In this case, profit obtained by bulk goods exporter is restricted, because transport cargo
Gross tonnage is less than the DWT of ship.Second of solution is to arrange ship berthing and/or sail out of the schedule at harbour to utilize tide
Condition.However, this may limit the handling capacity at harbour, and require anchorage regardless to berth and wait for take turns to their loading or unloadings
Opportunity.This also leads to additional cost, to reduce the profit of bulk goods exporter.
The above problem is also present in a kind of situation, i.e. two terminal port depth having the same, but ship needs are worn
Cross the shallower navigation channel of draft between two harbours.
To provide the background of the above problem, the Port Hedland (Port Hedland) of Western Australia, the port are please referred to
Mouth is for going abroad iron ore from Australia's transport.The iron ore quantity exported every year from Port Hedland is taken up an official post more than the world
What other harbour.
The regulation of the ship passage guide (vessel movement guidelines) of Port Hedland business office is for total
Most 330 meters of length (LOA), the ship of 60 meters of the beam (beam).It is more than 330 meters of ship in Harbour master's total length at discretion
Oceangoing ship may obtain the license steered a ship through navigation channel, and under certain tidal conditions and weather condition, these ships may be only
It is limited to berth daytime and navigate by water.
Some berths of Port Hedland allow bulk ship loading cargo to DWT, this causes maximum draft to be 19 meters.So
And the main channel between the berth and open waters only allows most 14 meters of drafts.Economically, it will preferably dissipate
Freighter is loaded into the deadweight tonnage for providing maximum allowable draft.And in the example of Port Hedland, to realize one 19 meters
The ship of draft can leave berth and pass through main channel, and the departure from port opportunity of ship will arrange according to high tide.Though
So this DWT for allowing maximum possible, but this leads to arrival of ship and sails out of the time delay at harbour.This is added significantly in turn
Transportation cost, therefore profit is caused to seriously affect.
In the case where keeping draft this ability is solved the problems, such as by building the bulk freighter of wider hull extremely
It is few that the beam is limited by main channel.Port Hedland business office can take the circumstances into consideration that the beam is allowed to be more than that 60 meters of ship passes through main boat
Road.However, this generally depends on the situation of daytime and tide.Accordingly, there exist high risk, the beam is much larger than 60 meters of (examples
Such as 80 meters or wider) ship can pass through delay for a long time and just enter berth or sail out of berth, or it is certain need to avoid it is such
Ship is navigated by water in main channel simultaneously.
For a long time, people's physical experience to it is necessary to need increase bulk freighter DWT, without change bulk freighter drinking water
The range of the ship passage guide specification of depth or the beam extremely beyond Port Hedland business office.Although increasing dissipating by Port Hedland
The aggregate tonnage of cargo can bring significant commercial interest, and bulk goods exporter possesses a large amount of financial resources and talent's money
Source, but this problem was at least never resolved at nearest 30 years.
