Abstract

A shipping process of a large module adopts the following steps: firstly, the method comprises the following steps: cleaning sundries in a dock; II, secondly: placing a plurality of docking blocks and skid blocks at set positions in a dock; thirdly, the method comprises the following steps: after water is injected into the dock, a dock gate is opened, so that the ship moves into the dock; fourthly, the method comprises the following steps: discharging water in the dock, and sitting the ship on the docking block and the skid to ensure that the position of the docking block and the skid is just the position of the rib of the ship; fifthly: a trestle and a ship deck pad pier are arranged between the wharf and the dock, and the trestle is a transition path for the module vehicle to travel from the wharf to the ship; sixthly, the method comprises the following steps: after the module vehicle bears the large module and runs from the wharf to the ship, the module vehicle is gradually separated from the large module to complete weight transfer; seventhly, the method comprises the following steps: the module vehicle is evacuated, and the trestle is removed; eighthly: the vessel is removed from the dock. The invention not only carries out the loading in the dry dock, but also solves the problems of pitching and rolling of the ship under the action of offshore waves, surge currents and tides; moreover, the controllability and the success rate of the shipment are improved.

Description

Shipping process of large module

Technical Field

The invention relates to a shipping process, in particular to a shipping process of a large module. Belongs to the field of ship loading in ocean engineering.

Background

At present, the conventional large module shipping process uses a module vehicle (SPMT) to carry the large module and move the module from the dock to the ship. In this process, the ship is subjected to great risk and uncontrollable loading, since the ship will pitch and roll under the action of offshore waves, currents and tides. In severe cases, the ship loading operation fails.

Disclosure of Invention

The invention mainly aims to overcome the defects in the prior art and provide a ship loading process of a large module, which not only loads ships in a dry dock, but also solves the problems that the ships can pitch and roll under the action of offshore waves, surge currents, tides and other environmental factors; and after the roll-on and roll-off loading of the module vehicle is finished, water is injected into the dock, so that the ship can be driven out of the dock, the whole loading process is not limited by environmental factors such as waves, surges, currents, tides and the like, and the controllability and the success rate of the loading are greatly improved.

The purpose of the invention is realized by the following technical scheme:

a shipping process of large modules is characterized in that: the method comprises the following steps:

the first step is as follows: cleaning sundries in a dock;

the second step is that: placing a plurality of docking blocks at set positions in a dock, and placing paddings on the upper surfaces of the docking blocks;

the third step: after water is injected into the dock, a dock gate is opened, so that the ship moves into the dock;

the fourth step: discharging water in the dock, and sitting the ship on the docking block and the skid to ensure that the position of the docking block and the skid is just the position of the rib of the ship;

the fifth step: a trestle and a ship deck pad pier are arranged between the wharf and the dock, and the trestle is a transition path for the module vehicle to travel from the wharf to the ship;

and a sixth step: after the module vehicle bears the large module and runs from the wharf to the ship, the module vehicle is gradually separated from the large module to complete weight transfer;

the seventh step: the module vehicle is evacuated, the trestle is removed, and the shipment work is finished;

eighth step: the vessel is removed from the dock.

In the second step, the distance between the docking blocks is equal to the rib position distance of the ship; and ensuring that the height of the docking block plus the height of the ship deck is equal to the height of the dock.

And in the third step, reasonably pressing and discharging the load of the ship to ensure that the bottom of the ship has enough clearance with the docking blocks and the skid.

The invention has the beneficial effects that: due to the adoption of the technical scheme, the ship is loaded in the dry dock, so that the problems that the ship can pitch and roll under the action of offshore waves, surge currents and tides are solved; and after the roll-on and roll-off loading of the module vehicle is finished, water is injected into the dock, so that the ship can be driven out of the dock, the whole loading process is not limited by environmental factors such as waves, surges, currents, tides and the like, and the controllability and the success rate of the loading are greatly improved.

Detailed Description

As shown in fig. 1-7, the present invention employs the following steps:

the first step is as follows: cleaning sundries in the dock 1;

the second step is that: as shown in fig. 1, a plurality of docking blocks 2 are placed at set positions in a dock 1, and a skid is placed 3 on the upper surfaces of the docking blocks 2;

the distance between the docking blocks 2 is equal to the distance between the ribs of the ship 4; reasonably arranging the height of the docking block 2 to ensure that the height of the docking block 2 plus the height of a ship deck is approximately equal to the height of the dock 1;

the third step: as shown in fig. 2, after water is injected into the dock 1, a dock gate is opened, so that the ship 4 moves into the dock 1 through a stranded cable; the ship 4 is reasonably pressed and unloaded to ensure that the bottom of the ship 4 has enough clearance with the docking block 2 and the skid 3;

the fourth step: as shown in fig. 3, the water in the dock 1 is drained, and the ship 4 sits on the docking block 2 and the skid 3, so as to ensure that the docking block 2 and the skid 3 are at the position just at the rib position of the ship 4;

the fifth step: as shown in fig. 4, a trestle 5 and a ship deck pier 8 are placed between the wharf and the dock 1, and the trestle 5 is a transition path for the modular vehicle 6 to travel from the wharf to the ship 4;

and a sixth step: as shown in fig. 5 and 6, after the module car 6 carries the large module 7 to drive from the dock to the ship 4, the module car 6 is gradually separated from the large module 7, and the weight transfer is completed;

the seventh step: the module vehicle 6 is evacuated, the trestle 5 is removed, and the shipment work is finished;

eighth step: the vessel 4 is removed from the dock 1.

The dock, the docking block, the skid, the ship, the trestle, the module car, the large module and the ship deck block are the prior art, and the unexplained technology is the prior art, so the details are not repeated.
