JPS592675B2 - How to convert a tanker into a plant carrier - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of converting a used idle tanker into a plant carrier.

When transporting plants by sea, the plants are usually loaded onto a Dicki purge and the purge is towed by a tugboat.

method is adopted. This conventional method.

(I) Damage to plants due to seawater injection or separation from Ditsky purge during transportation.

(II) Loss of the Ditsky purge and plants due to towline breakage or capsizing of the Ditsky purge.

(Tomo) The towing speed is slow and transportation takes a long time.

(ll[) Due to the relationships in items) to (III) above, insurance premiums for damage compensation are high.

(■ It takes a lot of effort for towing workers.

There were drawbacks such as.

The present invention has been proposed for the purpose of solving the above-mentioned drawbacks of the conventional transportation method for plants, allowing plants to be transported by sea safely and quickly, and making effective use of used idle tankers. By appropriately reducing the depth of the tank between the stern bridge deck and the bow deck, a section for carrying the deck purge is formed in the core, and an oil loading tank and cargo loading section are formed in the ballast tank. This is a method for converting a tanker into a plant carrier.

The present invention will be specifically explained below with reference to FIGS. 1 and 2.

In these figures, 1 is the main body of a used tanker, 1a is its stern bridge deck, 1b is its bow deck, and below the stern bridge deck 18 is a large engine room.

2 indicates the oil tank and 27 indicates the cargo loading compartment.

The present invention aims at making the depth of the oil tank 2 and cargo loading compartment 2' between the stern bridge deck 1a and the bow deck 1b of the used tanker main body 1 appropriately shallow as shown by the broken line, and installing a deck purge at that location. The used tanker main body 1 is converted into a plant carrier by forming a storage compartment 3 and forming the remaining oil tank and cargo loading compartment into a ballast tank.

When transporting plants by sea using the plan carina modified as described above, the ship is submerged as shown in Figure 3 by injecting seawater into the baranut tank while the ship is at rest in a port. Raise its waterline.

After positioning the Ditsuki Purge 4 carrying the plants onto the Ditki Purge compartment 3 using a tug boat or the like, and then draining the seawater in the Baranut tank, the ship will be able to install the plant in the Ditki Purge compartment 3. With the Ditsky Purge 4 containing the above components mounted on the tower, its water line descends, resulting in the state shown in FIGS. 1 and 2.

Next, the ship propels itself on the sea to transport the plants to a destination port, etc., and unloads the plants by performing the reverse operation described above.

Since the method of the present invention has the above-described configuration, according to the present invention, (1) a used floating tanker can be converted into a plant carrier with extremely simple modification work, and its effective utilization can be achieved.

(2) It is possible to obtain carriers that transport plants quickly and safely by sea to their destinations at low cost.

(3) It is possible to realize a plant carrier that requires less labor for marine transportation workers.

The following practical effects can be mentioned.

Next, in the example shown in FIGS. 4 and 5, one tanker body 1
An example is shown in which the interiors of both sidewall portions 5 are also used as ballast tanks, and a Dicke purge column mounting section 3 is formed between these sidewall portions 5.

In this case, a Dicki barge introduction door 6 may be provided at the bow of the ship, and the Dicki purge loaded with plants may be introduced into the Dicki purge loading section from the door 6.

[Brief explanation of drawings]

Figures 1 to 3 are schematic diagrams of a plant carrier modified by the method of the present invention, with Figure 1 being a side view, Figure 2 being a view in the direction of arrow A in Figure 1, and Figure 3 being a ballast tank. A side view with water injected, and Figures 4 and 5 are schematic diagrams of an example in which both sidewalls are also used as ballast tanks. Figure 4 is a side view, and Figure 5 is a view in the direction of arrow B in Figure 4. be. 1: Tanker main body, 2 oil tanks, 21: Cargo loading compartment, 3: Ditski purge loading compartment, 4: Ditski purge, 5: Side wall section, 6: Door.

Claims (1)

[Claims] 1 By reducing the depth of the tank section between the stern bridge deck and the bow deck of the tanker to an appropriate level, a section for carrying the deck purge is formed in the core section, and the oil loading tank and cargo loading section are replaced by the ballast tank. A method for converting a tanker into a plant carrier.
