Abstract

PURPOSE:To have an efficient loading operation onto a ship by introducing a carrier vessel between a wharf and a support provided facing it, placing heavy objects on a track, installed being bridged over the wharf and support, by the use of a track with jack, and then holding the objects with a jack on the ship. CONSTITUTION:A carrier ship is introduced to between a wharf and a support 5 provided facing it. A track composed of two or more rails 4 for trucks is extended from the warf to the support 5 over said carrier vessel 2 and is held fast. Heavy objects 1 are placed on a truck with jack, which runs on this track construction 4 to shift the objects 1 to the track construction 4 situated over the carrier ship 2. Then the jack 10 on the ship 2 transfers the objects onto the ship 2, and the track construction 4 is retracted onto the wharf 3 to finish loading of objects 1. According to this arrangement, an effective loading of heavy objects can be obtained regardless of displacement of the ship 2 in the vertical direction.

Description

DETAILED DESCRIPTION OF THE INVENTION The invention relates to a method for loading bulk items such as plant modules onto a ship.

A so-called roll-on method using a trolley is widely used as a method for loading heavy objects such as plant modules onto ships. However, in the conventional roll-on method, the cart is directly mounted on the carrier from the quay, so great care must be taken to prevent the carrier from being displaced by external forces such as waves and currents. There are 9 problems in that the ramp structure that connects the ship and the ship must be made larger, which increases the cost of the equipment.

The present invention was devised in view of the problems of the conventional roll-on loading method, and provides a method and method for efficiently loading heavy goods without being significantly affected by displacement of a carrier due to external forces. The purpose is to provide a device suitable for implementation.

Therefore, in the present invention, a plurality of structures for running bogies are advanced from the quay above the berthed ship, and then a bogie loaded with heavy objects is made to run from the quay over the structure to move it above the vessel. Then, the heavy object is lowered from the truck onto the structure and the truck is retreated to the quay side. After that, the heavy object on one structure is jacked up and held by the jacking device installed on the ship. Its basic feature is that after the structure is retreated to the quay side, heavy objects can be loaded onto the ship by being jacked down onto the ship. Further, the present invention provides a device suitable for carrying out such a method, including a plurality of structures for running bogies that can advance in a substantially horizontal direction above a ship berthed from a quay, and a tip end of the structure that has advanced. A support body erected on the seabed to support the structure, a truck for transporting heavy objects that can run on the structure and is equipped with a jacking device for loading and unloading heavy objects, and a platform for jacking up heavy objects placed on the structure. Another basic feature is that it consists of a jack-up device capable of being jacked up. Since the present invention does not use a ramp system that directly connects the quay and the ship, heavy objects can be loaded efficiently without being greatly affected by the displacement of the ship due to external forces such as waves.

Hereinafter, the present invention will be described with reference to the drawings.

FIG. 1 shows a state of implementation of the present invention, in which (1) shows heavy objects such as plant modules to be loaded on a ship, (2) shows a carrier ship berthed, and (3) shows a quay.

In the present invention, first, as shown in FIG.
) A plurality of structures (4) (arms) for running the bogie are advanced in a substantially horizontal direction from the quay (3) above the quay (3). This structure (4) can be moved forward and backward from the quay by appropriate moving means (for example, a roller moving device, etc.). A support (5) for supporting the tip of the structure (4) is located on the seabed at a distance of -C from the quay (3) to the carrier ship (2).
is erected, and as shown in Figure 1 (b), the extended structure (4) is supported at one end by the quay (3) and at the other end by the support (5). . In this embodiment, the support (5) is constituted by a pile erected on the seabed, and the lower surface of the extended structure (4) slides into contact with the upper surface of the pile.

On the shore a (3), a heavy load (1) is loaded onto a truck (not shown), and the truck is moved over a structure (4) to be positioned above the carrier (2).

Then, as shown in Figure 1 (C), at this position, the heavy object (υ) is lowered from the truck onto the structure (4) 1, and the truck is retreated toward the quay (3). A vehicle equipped with a jack-up device for loading and unloading heavy objects, such as that used in the roll-on system of The trolley (6) that travels has a jacking device (8) on its upper part, and this jacking device (8) supports a pedestal (9) with a gate-shaped cross section from its underside.
) A heavy object (1) is loaded on the top. And the trolley (
6) is positioned above the carrier vessel (2), the jack-up device (8) and the heavy load (1) (heavy load and pedestal,
(Same below) is jacked down, both legs of the pedestal (9) are lowered onto the structure (4), and only the free truck (6) is retreated toward the quay (3).

Next, as shown in Fig. 1), the jack-up device α1 provided on the carrier (2) is extended, and the heavy object (1) on the structure (4) is removed from between the plurality of structures (4). Hold it up. Then, the structure (4) from which the heavy object (1) has been unloaded is retreated toward the quay (3). The heavy cargo (1) is lowered onto the carrier vessel (2) and installed in its proper position to complete the loading. The jack-up device QQ on the carrier (2) is a fixed type.

Alternatively, it may be installed on a cart on a ship.

In this way, in the present invention, the quay (3) and the carrier ship (2) are not directly connected, and the structure (4) and the jack-up device (
The heavy goods (1) are transferred to the transport vessel (2) by hand.
), loading can be carried out without being affected too much by the rocking or displacement of the carrier vessel (2) caused by external forces such as waves or currents.

According to the present invention described above, direct connection between the quay and the ship is avoided, and heavy objects are loaded onto the ship instead of being transported by jacking up devices on the structure and the ship. Heavy cargo can be loaded without being significantly affected by the rocking or displacement of the ship due to external forces, and this method can be carried out favorably, so a large ramp structure is required. This has the excellent effect of allowing heavy loads such as plant modules to be carried out extremely efficiently without any problems.
