Abstract
A boarding system is disclosed. The boarding system comprises a landing platform; A cylinder fixedly installed perpendicular to one side of the side wall of the offshore structure; A cylindrical piston arranged to penetrate the cylinder and having one end fixed to one side of the landing platform; And an elevating device for vertically elevating the landing platform.
Description
The present invention relates to a boarding system.
Offshore structures, such as floating liquefied natural gas production facilities (FLNG) and floating oil production storage and unloading facilities (FPSO), typically ship small ships and provide the necessary materials and manpower.
And, offshore structures are equipped with multiple layers of landing platforms to allow supplies or manpower to be supplied to offshore structures in small vessels, even when waves, tides and drafts occur.
However, due to the difference in level between the small ship caused by the interlayer spacing of the landing platform, there is a danger that the manpower or the material may be transported and the pirate or unauthorized personnel can easily access the offshore structure .
Korean Prior Art Patent Application No. 2012-0053913, which is a prior art that can be considered to solve such a problem, discloses a ladder for lifting and lowering a ship which is moved or rotated by a flow amount of a ship due to the height of a peak or a sea condition, Pier), the operator can safely pass through the technical idea is started.
However, the above-described prior art is an invention that can be considered only when one of them, such as a wharf, maintains a stable state regardless of the sea condition, and there is a limit that can not provide a stable passage between two objects existing on the sea.
In addition, when the height difference between the two objects to be moved is large, the ladder for lifting the ship must be installed with a large inclination, which makes it difficult for the worker to move, and there is also a risk of falling.
The present invention is intended to provide a boarding system capable of safe transfer of manpower or material regardless of the height difference between the offshore structure and a small ship or irrespective of extreme flow of a small ship due to poor marine conditions.
The present invention is intended to provide a boarding system that facilitates the access blocking of pirates or unauthorized persons.
Other objects of the present invention will become readily apparent from the following description.
According to an aspect of the present invention, a landing platform in the form of a plate; A tube-shaped cylinder fixedly installed to one side of the side wall of the offshore structure; A cylindrical piston arranged to penetrate the cylinder and having one end fixed to one side of the landing platform; And an elevating device for vertically elevating the landing platform.
The cylinder comprises a tubular cylinder body; A cylinder cover having a first through-hole formed therein, the cylinder cover being coupled to an upper portion of the cylinder body to form a space separated from the upper surface of the cylinder body; And a second through-hole having a diameter corresponding to an outer diameter of the piston, wherein the piston includes a plurality of discs spaced apart from each other in the inner side of the cylinder body, the piston having a first through- And may be raised or lowered along a path formed to connect the through-hole.
The boarding system of the ship may further include an opening / closing part for linearly reciprocating the closing member to close or open the spacing space formed in the cylinder.
Here, when the spacing space is closed when the upper surface of the piston, which is lowered in accordance with the descent of the landing platform, is located in the cylinder body, the uppermost surface of the uppermost disk, which is in contact with the closing member and the piston, Can be formed as an airtight space.
The airtight space may be formed to provide an air pressure that suppresses the rise of the landing platform when a surge force is generated by the waves on the landing platform floating on the sea surface.
The piston may be formed in a "C" shape formed by bending both ends toward the upper side from the lower side.
Other aspects, features, and advantages will become apparent from the following drawings, claims, and detailed description of the invention.
According to the embodiment of the present invention, it is possible to safely transfer manpower or material regardless of the height difference between the offshore structure and the small ship, or the extreme flow of the small ship due to poor marine conditions.
It also has the effect of making it easier to block access to pirates or unauthorized personnel.
