Description

Integrated lamp block {MOVABLE-RAMP BLOCK}

The present invention relates to a method of integrating a ramp (MOVABLE RAMP) and a corresponding hull block (BLOCK) installed in a PCTC ship.

In recent years, liquid cargo such as a small amount of chemicals and heavy cargo such as machinery are also transported in a dedicated container ship, and almost all cargo is transported in a container ship except for cargoes that are difficult to load in container ships such as crude oil, grain, and iron ore. The increase in container cargo is due to the advantages of safe cargo transportation and high speed even in bad sea environment. Meanwhile, about 7% of the cargo being transported by general cargo ships is converted to container cargo every year, and the global maritime container volume is expected to increase by more than 7% per year. Considering the progress of containerized sea freight, increased e-commerce, and increased cargo volume due to the full operation of the WTO system, it is expected to increase by 9%, higher than the above estimate. As such, the outlook for container ships is very bright, and the trend for large-sized vessels will likely continue.

Container ships can be classified into the following three types according to the unloading method.

Lift-on / Lift-off (LO / LO), a container ship that unloads containers by container wharf crane or main ship crane, and L-shaped or T-shaped cell guides inside the cargo hold. A frame called a guide is built and the containers are stacked one after another. In particular, a ship in which the entire cargo area is divided into cells is called a container-only ship and is generally called a container ship.

The other is Roll-on / Roll-off (RO / RO), also commonly referred to as the 'ro-ro', which is usually a container directly to a trailer or forklift via a stern ramp installed at the stern. It is a container ship that loads and unloads oil. It is suitable for ports that do not have well-equipped port facilities because they do not need separate loading facilities.

In the hybrid method, a ship with a cell guide is arranged on the ship's bow and unloaded by a shore crane or a crane installed on a ship. At the same time, a stern ramp and a roll-on / roll-off deck are used to unload containers or roll-on / roll-off cargo with a trailer or forklift. Use the lift on / lift off method and the roll on / roll off method simultaneously.

At present, a ramp, that is, a ramp (RAMP) is essentially installed as described above for vehicle traffic or cargo unloading in a PCTC ship. Current methods of installing these lamps will be installed at the completion of the ship's construction. When installing such a lamp on a ship, due to field production errors and accuracy (arranged) errors in the production of each block by the block, excessive air flow due to correction and correction during installation occurs, and the lamp is moved to a portable type ( In the case of manufacturing by driving), if the operation error occurs, such as the problem of reinstalling the front of the ship drying air is a problem that causes a huge loss in productivity. This is because the hull structure must be changed in case of incorrect installation of the lamp or an error in the site accuracy of the lamp installation.

In addition, the entire process related to equipment movement and equipment installation movement of various vessels occurs during the construction of this lamp, and delivery is imminent. Therefore, various operations are affected by the process delay. The reliability of the ship owners is lowered, and a huge expense is lost.
