The method of loading and unloading on the trimaran floating cargoes of water in the hold and back

 

(57) Abstract:

The invention relates to shipbuilding, in particular to a method of loading and unloading on the trimaran floating cargoes of water in the hold. The method consists in the fact that they use the trimaran, average housing which has a bilge gate and a bottom disclose shutters, open bilge gate and sash bottom, start coming out again for the cargo, ensuring its place in the hold. After placing the load close bilge gate and bottom sash, pumped from the bilge water. Achieved handling oversized cargo directly from the water into the hold of the middle hull of the trimaran. 5 Il.

As is known, the loading and unloading of the majority of vessels of different kind of goods in ports by using shore crane, pump, etc. equipment. The current level of development of loading and unloading equipment can lift and carry in boat loads weighing several tens of tons. Themselves of the court, except for special, do not have equipment to conduct loading and unloading operations, due to the uselessness because are loaded and unloaded in ports.

There are such court, as the ferry landing, which are loaded from the shore ramps h is the m-world fleet has no ships, designed to handle one-time receptions large and multi-thousand tons of cargo. Because to move such cargo on a vessel required loading equipment, which in the foreseeable future is not going to happen, and the need for transportation of such goods is overdue, for example, transportation multi-thousand tons ' ice-blocks, I proposed a method of handling operations consisting in the movement of cargo from the water directly into the hold using a special design of the ship.

The aim of the study is to develop a method of loading and unloading of large, multi-thousand tons, one-piece cargo moving it directly from the water into the hold through the special design of the bottom of the middle hull and fore or aft secondary hull.

The need to develop transport vessels for the transport of multi-thousand tons ' ice-blocks and how they are handling has arisen in connection with the problem of shortage of drinking water in countries with a hot climate and the study of delivery in these countries ice from Antarctica, Greenland, etc. Physical properties of frozen water - ice, his buoyancy in the water and the uniqueness of this phenomenon in nature on the th, hand.

Technology delivering ice includes the stages of production from the array of icebergs and glaciers, loading ships, transporting and unloading at destination. In this work we consider the stage of loading and unloading. For its implementation were developed by the special design of ships-trimarans that are loaded with the bow or the stern.

As the source water was considered the glaciers and icebergs of Antarctica. Obviously, there are three possible options for the delivery of water:

1. In liquid form is very intensive on rastarivanie ice and unacceptable terms of loading.

2. In the form of small pieces of ice here, the energy consumption is lower but significantly increase the capital cost of various equipment; also decreases the density of loading of the hold and increase the time of loading.

3. In large chopped beams of ice weighing tens of tons, but the loading of the vessel is delayed for weeks, the amount of work for tugs and crane equipment increase hundreds and thousands of times, and so on

All of the above options is unacceptably high increase the cost of delivered water, it is therefore proposed method of delivery in vroma. Variant is characterized by the minimum expenses for the ice beam, its delivery to the vessel and placing it in the hold of the vessel. Production of ice is on the iceberg, ice shelf or other source of ice, providing the required size of the ice beams. The ice beam is obtained by way of the melting of the contour from an array of ice using ice-cutters, invented to solve this problem. Because the beam of ice will have to transport to sleep in the hold of the middle hull of the vessel, its shape and dimensions must conform to the dimensions and typical U-shaped hold. Cut the bars down into the sea and then with assistance of tug boats pull up to standing in some distance to the trimaran-ship.

This objective is achieved in that the use of the trimaran, average housing which has a bilge gate and a bottom disclose shutters, open bilge gate and sash bottom, start coming out again for the cargo, providing its placement in the hold, then close the sash bottom and bilge gates, pumping sea water.

In Fig. 1 shows a diagram of a transport ship is a trimaran ship-NAM.

In Fig. 2 shows a diagram of the middle hull of the trimaran ship-NAM otkryvautsya ship-NAM.

Structurally, the ship is a trimaran, because this design provides the greatest stability, buoyancy and a margin of safety during loading and unloading and transportation. Accommodation ship engines in addition to the average case in the side casings of the auxiliary, as in conventional trimaran, turned into the equivalent of a major, gave the high maneuverability of the trimaran required for loading and unloading of bulky goods, being in water.

Consider the trimaran ship-NAM location bilge gate in the bow of the average case. The vessel 1 consists of three buildings (Fig. 1): average (cargo) case 2 and the side wings 3. All buildings are equipped with ship power plants (with propellers 4). The average hull 2 of the vessel is a cargo. Housings are fastened together micorphone bracket 5. On deck 6 is the add-on 7 and on the sides of buildings - add-8. The fore part of the average case (Fig. 2) consists of the nasal bilge gate 9 (gate is closed) and 10 (gate open), and whole upper portion 16. The height of the surface part of the target provides loading and unloading passage surface is (shutters closed) and 12 (sash disclosed).

Consider the operation of loading of the vessel (Fig. 3-5). Open bilge gate 9 and the bottom sash 11. Fresh water fills the hold of the middle hull of the trimaran. Is printablepage secondary hull to the calculated values, providing a reception beam of ice or cargo directly from the water into the hold through the open bilge gate and bottom sash. Ship maneuvering engines, runs over to the ice beam 13 or other cargo (for example, Barkan), placing it inside the hold. Next, close the sash, bottom and bilge gate. Outboard water left in the bilge is pumped overboard and the load is placed in the hold. Vessel is ready for shipment and should be in the port of destination.

In case you need to take underwater cargo loading can be disclosed through the leaf bottoms without disclosing bilge gate. The vessel is equipped with a variety of crane equipment, which can be used for lifting loads, objects from the bottom.

The surgery ship unloading is the reverse of loading operations.

Similar to the operation of loading and unloading can be carried out by the trimaran ship with the location of the bilge gate aft secondary hull.

SPO is, trichosis that use vessel-trimaran, average housing which has a bilge gate and a bottom disclose shutters, open bilge gate and sash bottom, start coming out again for the cargo, providing its placement in the hold, then close the sash bottom and bilge gates, pumping sea water.
