Description
Technical Field
The invention belongs to the field of submarine optical cable laying, and particularly relates to a submarine optical cable laying system.
Background
Submarine optical cables, also called submarine communication cables, are laid on the seabed for large-capacity information transmission between islands or from islands to mainland. The submarine optical cable system is divided into an onshore facility and an underwater facility, and the submarine optical cable is the most important and fragile part of the underwater facility. The submarine optical cable is laid on the seabed by optical fibers wrapped by various protective layers, and the seawater and the protective layers can prevent the interference of external electromagnetic waves, so that the confidentiality of the submarine optical cable is high; the design life of an undersea optical fiber cable is typically 25 years.
Submarine optical cable engineering is recognized by countries around the world as a complex and difficult large-scale project. In shallow sea, the cable is buried, for example, in sea area with water depth less than 200 m, and in deep sea, the cable is laid. The water jet burying is the main burying method. The bottom of the embedding equipment is provided with a plurality of rows of water spraying holes which are distributed on two sides in parallel, and during operation, each hole simultaneously sprays high-pressure water columns to the seabed to flush away sediment on the seabed so as to form a cable trench; the upper part of the device is provided with a cable guide hole for guiding the optical cable (optical cable) to the bottom of the optical cable ditch, and the ditch is automatically filled by tide. The burying device is dragged by a construction ship to advance, and various instructions are made through the working optical cable. The cable laying machine is generally laid on the surface of the sea bottom by the dead weight of the optical cable without underwater burying equipment.
The submarine optical cable is usually buried in a place 3 meters deep under the seabed, and due to large change of the terrain and the substrate of the seabed, if the construction process of the optical cable is not controlled in place, the submarine optical cable may be suspended, stacked or not protected in place, and the optical cable in a part of the protection area may be exposed along with the lapse of time. The cable may be destroyed by the fishing vessel anchoring and using the trawl to catch the fish, even by the shark gnawing. The bad weather such as sea heavy wind and wave may cause the slow repairing work.

Example 1
Relevant submarine routing reexamination is carried out according to routing exploration technical data provided by design, and the following submarine conditions are known: rechecking the seabed substrate to determine whether the seabed substrate is suitable for the flushing and burying construction and whether the seabed substrate can be buried to a required depth; and (4) rechecking the seabed obstacles to know whether the seabed obstacles obstructing the burying construction exist or not.
And (4) detecting and hoisting the submarine optical cable and installing cable laying equipment. After the submarine optical cable is delivered, appearance inspection is firstly carried out, and then pre-construction test is carried out according to the corresponding optical cable test standard. And after the submarine optical cable is placed upside down to a designated position on a construction ship through a cable-reversing channel arranged on a wharf by a manufacturer, the submarine optical cable disc is reinforced by constructors.
And (5) constructing the submarine optical cable landing platform. And the construction ship is in place by the platform in low tide time. Starting the cable laying machine to slowly deliver the optical cable, and launching the optical cable at a certain water-entering angle. And meanwhile, starting an anchor head of the anchor machine to drive the towing steel rope to pull the end of the optical cable to enter a special optical cable channel of the embedded plough, then penetrating through the whole upper platform of the protective pipe, and filling a pulley at the landing position of the optical cable of the platform to protect the surface of the optical cable from being damaged. After the optical cable reaches the terminal point through the protective tube (as shown in the figure), the optical cable is temporarily fixed and then enters the next procedure so as to prevent the optical cable from being pulled out when the optical cable is buried deeply in the middle sea area.
Laying construction of the middle section of the submarine optical cable. According to the actual survey on site and the design condition of the optical cable route, the construction adopts a pre-cast traction anchor traction mode to move the ship, and the construction ship is provided with one traction anchor near the terminal platform along the extension line of the optical cable track. Before construction, the position and the posture of the embedded plough before laying are checked, and the landing posture of the embedded plough is checked by a control room monitor on the ship. Alternately starting the ship-moving winch and the burying plow traction winch to adjust the water inlet angle of the burying plow traction steel rope, and simultaneously, correspondingly and slowly sending out the signal cable and the water pump hose. In addition, the stress condition of the sea optical cable is monitored and mastered through monitoring equipment on the ship. The construction ship is easy to deviate from the designed route axis under the influence of tidal current and wind speed, the auxiliary ship assists in throwing one positioning anchor at each of four corners of the cable laying ship, so that the ship position of the cable laying ship is relatively fixed, then a traction steel wire is put, the ship moves slowly through a winch stranded steel wire on the ship, the auxiliary ship assists in moving the four positioning anchors after moving for a certain distance, and the operation is repeated in such a way, so that the ship position is controlled to control the deviation of a cable laying route. The angle should be in a smooth transition when the optical cable is buried to the turning point.

And the bending radius of the optical cable entering water and the optical cable entering the J-shaped protective pipe opening is controlled to be larger than 2.0m during login, so that excessive friction between the optical cable protective layer and the surface of the platform is prevented. The cable tension is controlled below the design tolerance to prevent sudden starts and stops of pulling. And the traction speed of the cable distributing machine and the anchor machine is checked at any time, and meanwhile, the diver launches to monitor the contact condition of the optical cable and the seabed, the relative position of the optical cable and the embedding plough, the stress condition of the optical cable at the bell-mouth folding point and the bending radius of the optical cable.
And laying and inspecting the middle section of the submarine optical cable, wherein the construction of laying and burying the optical cable in the middle section sea area mainly controls the safety of the optical cable, the laying depth of the optical cable and the deviation of a cable laying route. Controlling the safety requirement of the optical cable to keep the bending radius of the optical cable at the turning position of the optical cable channel on the construction ship to be larger than 15 times of the diameter of the optical cable; the bending radius of the optical cable entering the water tank is more than 15 times of the diameter of the optical cable. The required error range of the optical cable burying depth is controlled within +/-10%. On the optical cable laying ship, a buried depth monitoring system for submarine optical cable laying operation is equipped. The system can detect the depth of the optical cable buried in the plow body of the burying machine and detect the attitude of the plow body, thereby realizing the dynamic detection of the optical cable buried depth of the burying machine. In order to control the optical cable to be buried and meet the design requirements, the following test measures are mainly adopted:
1. before construction, a plow is embedded and put into the seabed, so that the skid is required to be in full contact with the seabed;
2. the water supply pressure of the water pump unit is not less than 2.0MPa in the construction process;
3. the construction burying speed is controlled at 2-2.5m/min.
