Abstract
Description
The present invention relates to a submarine cable laying method, and more particularly, to install the submarine cable along the trench excavated on the bottom, even if the trench is narrow and bent for reasons of design and economic reasons can be accurately laid the submarine cable The submarine cable laying method and the detector used therefor.
As is well known, subsea cables (or subsea pipelines) are laid on the sea floor to supply gas or oil, deep water or communication or power.
One conventional method of laying a subsea cable is to secure the
However, this pooling system is less expensive, but installation of submarine cables is possible only in the straight section, so if there is an obstacle on the sea floor, it must be installed far away in a straight line rather than curved. In addition, this pooling system is applied in intertidal zones in short intervals, and due to the influence of algae, long-distance work was impossible.
On the other hand, there is disclosed a method of installing a submarine cable (or subsea pipeline) in a trench of a curved portion using a lay barge, but this is not only economical because the equipment is expensive, but also a design cable route displayed through GPS on the ship. Since the installation of the submarine cable at the location of the trench determined by the surveying and depth surveying, it was difficult to accurately locate the trench and insert the submarine cable into the trench bottom (center) precisely under the influence of tidal currents. There was a problem that the accuracy is lowered.
The present invention has been proposed to improve the above-mentioned problems, the object of which is to install the submarine cable while verifying the position and position of the submarine cable seated in the trench excavated along the cable route using the detector submarine cable It is to provide a submarine cable laying method that allows easy and accurate laying at the center of the trench.
Another object of the present invention to provide a detector used in the submarine cable laying method.
In the above-described object, in the submarine cable laying method of laying the submarine cable while lowering the submarine cable from the barge to the bottom surface of the trench excavated along the cable route of the submarine design, the detector connected by the barge and the rope is introduced into the subsea. As the detector moves along the touch point where the submarine cable and the bottom (center) of the trench touch each other, it detects the shape of the trench and the seating condition of the submarine cable and transmits the signal. It is achieved by a submarine cable laying method characterized in that it comprises a step to enable.
The other object described above is installed so as to move along a touch point where the submarine cable and the bottom surface of the trench touch each other, the camera is mounted and configured to check the form and state of the trench, and a transmitter is installed to install a receiver on a barge. Transmitting and receiving is possible, and by installing a buoyancy tank injecting air is achieved by a submarine cable laying method detector, characterized in that it is configured to lift the submarine cable together while rising by buoyancy.
The submarine cable laying industry according to the present invention can check the form and state of the trench visually from the barge by using a camera when laying the submarine cable, and can accurately determine the position coordinates and the level of the submarine cable using the transceiver. This makes it possible to accurately install submarine cables in the center of trench bottoms excavated along the cable route in the design, especially in curved trenches. In addition, by using a detector to reduce the amount of work of divers to realize an accident-free, improve workability and shorten the construction period. In addition, if the submarine cable is not accurately seated on the bottom of the trench, it is very easy to adjust the position of the submarine cable because air can be injected into the buoyancy tank of the detector to lift the submarine cable easily using buoyancy and then mount it again correctly. It has an easy effect.
Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. 2 is a view showing the submarine cable laying method according to the present invention, Figure 3 is a side view showing a detector used in the present invention, Figure 4 is a view showing a state that the submarine cable is correctly seated in the trench to be.
2 and 3, the method for laying the submarine cable according to the present invention will be described. First, the
Then, the
According to the present invention, the
Subsequently, the submarine cable laying process will be described. When the
On the other hand, while checking the position of the
In this manner, when the work to accurately seat the
For reference, the submarine cable mentioned in the present invention will include not only a flexible cable but also a subsea pipeline to which a plurality of pipes are connected.
Applying the submarine cable laying industry according to the present invention, when laying the submarine cable can be laid while checking the form and state of the trench by using the camera, and precisely position and level on the coordinates of the submarine cable laid through the transceiver You can check it. In addition, when the submarine cable is installed in trenches excavated along the cable route, if the position is misaligned, air can be injected into the buoyancy tank of the detector to lift the submarine cable using buoyancy to accurately seat it again. Therefore, according to the present invention, even if the trench is excavated not only with the straight portion but also with the curved portion, the exact position and state can be grasped to accurately install the submarine cable along the trench.
While the invention has been shown and described in connection with specific embodiments, it will be understood that various modifications and variations can be made without departing from the spirit and scope of the invention as indicated by the claims. Anyone can grow up easily.
