In the vast seas of Zhoushan, under the surging sea, there are submarine cables, known as the "deep sea lifeline", and send 10,000 lights to the island city.

The Zhoushan Islands are the largest islands in my country. The submarine cable is wide and long, with a long path, with a total length of 1441 kilometers. They connect the mainland power grid with Zhoushan Grid, ending the history of the "island" operation of Zhoushan Power Grid.

However, once the submarine cable buried under the sea bed is damaged, it will cause huge economic losses, and it is difficult to repair it in a short period of time, and the island may also fall into darkness. In order to maintain the safety of submarine cables, the State Grid Zhoushan Power Supply Company is building a three -dimensional maintenance system with "satellite in the sky, a patrol ship at the sea, and a radar offshore with radar".

Summer is during the peak of electricity, and it is also the time when the maintenance tasks of the sea cables in the year are the heaviest. Recently, we followed Shen Zhenyu, assistant to the coastal monitoring team of Zhoushan Power Supply Company, and Li Chaogen, an assistant to the team leader of the submarine cable monitoring squad leader, to patrol the sea together to experience the hardship of the cable work in the hot summer.

365 days a year to patrol the cable

At 9 am, the temperature on the Dinghai Rifle Bay Wharf has approached 30 ° C. Shen Zhenyu took us to carry a small boat that was enough to accommodate three or four people to the Yushan Sea Sea Reserve.

"Old Li is on duty at sea all year round, and we can see him immediately." The "Lao Li" in Shen Zhenyu's mouth was Li Chaogen, and the captain of the sea cable emergency disposal. "He can't go ashore?" We couldn't help asking. Shen Zhenyu carefully explained that there are 9 220 kV sea cables and 1 underwater communication optical cable. It is the life power supply of Yueshan Petrochemical Base. It has greatly influenced. Therefore, the ocean cable emergency disposal ship patrolled in the Yushan waters all year round. There was no special circumstances without returning to Hong Kong. Only when the seal cable guards had a short shore to rest time when they changed their shifts.

I heard that today is the most important sea cable protection area in Zhoushan waters. We have become nervous and excited. The sea breeze screamed from the ears, and the boat galloped forward, so we felt a touch of coolness. Soon, a number of large characters printed with "Each Cable Emergency" and the anchor stopped on the sea. The boat gradually leaned on it. Under the action of the wind and waves, the boat was shaking well, and the height of the two boats was more than one meter. Seeing the time, the crew saw the opportunity and pulled us up. "The ship in front, the waters in your ship are the seaside cable protection area, prohibit the anchor! Please speed up as soon as possible!" Before we slowed down, the sound of shouting came from the driver's platform. We followed the crew to the driver's platform , A hot air coming. It turned out that Li Chaogen, who was on duty, found that a freighter had fallen sharply when a cargo ship sailing in the sea cable protection area, which was likely to break down. He immediately shouted to the other party.

Soon, the cargo ship gave a response: "My boat leaks a sudden water and is fixing myself. Obief your command and not break down!" Although Li Chaogen was still unwilling, he couldn't care about wiking the sweat on the forehead Pearl, staring at the ship firmly, talking with them from time to time to master the maintenance progress. After 30 minutes of nervous and long minutes, the freighter was blocked and drove away from the seaside reserves at a normal speed.

Li Chaogen frowned tightly, and then he opened it, picked up the towel hanging around his neck and wiped the sweat on his face. "The biggest 'enemy' of the submarine cables is that the sudden break -in of the anchor ship in the protected area." Li Chaogen, who has been protecting the cable for four years at sea, has long known for all kinds of assignments that might damage the sea cable: the sharp anchoring party will be a sharp anchor party meeting It is very likely to drag four or five hundred meters on the bottom of the sea. In addition, they must be alert to digging, drilling, piles, bottoming fishing, Zhangwang, breeding and other behaviors.

When talking to us, Li Chaogen's eyes almost left the electrical sea map. "This small electronic screen can help us a lot! It can collect the ship AIS data of the ship, and the nearby ships are dynamic at a glance." Li Chaogen said, "It is too much eye, and you are looking at the computer screen for three or four hours to watch the computer screen. It is common for eyes to sour tears. "We saw those blood -filled eyes from his black face.

Witness the change of the concept of fishermen

Near noon, the scorching sun was shining straight, and the temperature in the cab with no air conditioner was higher. "Wait for the boat to get cold." The high temperature made us a little irritable, but Li Chaogen started the anchoring machine to collect the chain in an orderly manner. "This is the case every summer, we are used to it." Li Chaogen said with a smile. One day, their clothes were wet and dry, dry and wet, and a large sweat stained the clothes like a map.

"Although we now have advanced equipment, if the ship closed AIS, we cannot receive its signals." To this end, they will cruise around the seaside reserve every day to check the situation at the sea.

"Why do you want to drive out at the orgasm?" Li Chaogen explained patiently that the place where they anchored on weekdays were a shallow beach area, and the low -ebb period was most likely to occur to shallow the submarine cable, so they must be here. When it rises to 2 meters, the general ships will not be stranded, so they can rest assured that they will go out to patrol.

Accompanied by the sound of "Da Da Da", the ship sailed. We looked out from the driver's platform and saw that the sea was rising, the waves were rolling, and the scenery was very spectacular. The sea cable guards are accompanied by the sea, shouldering the heavy responsibility of guarding the sea cable, and also experienced the thrilling of the accident against the accident. To halfway, all the sea was stable, and Li Chaogen told us the experience of defending the seaside.

Once, they found in the cruise that the speed of a cargo ship behind them suddenly slowed down. Everyone immediately entered a state of tension, called as soon as possible, and quickly turned around the bow to the cargo ship. Nevertheless, it was still slow. When connected, the cargo ship was anchored under the sea cable protection area due to the machine failure.

"At this time, an anchor must not be harvested at this time! Such a large number of tons of large anchor moves slightly, and it will damage the sea cable." Li Chaogen said that they communicated with the opponent's crew. The huge losses and influences that the seas cable may bring is inestimable. You may even bear legal responsibility ... "In just 10 minutes, the other party agreed to cut anchor and promised to leave the protected area before the anchor was repaired.

At this time, there were more ships that broke into our sight. Li Chaogen opened the tweeter on the ship and started to play: "The ship in front, you have entered the sea cable protection area, and you cannot perform the following homework ..." At this time, the emergency disposal of the sea cable was like a mobile broadcasting station to promote the warning. They also often issue brokers on board, telling the crew to tell the crew to clarify the scope of the seas, the significance of the seaside cable, and the legal liability for destroying the seal cable.

Li Chaogen is very pleased. In recent years, the phenomenon of illegal operations has become less and less, and the awareness of fishermen's seaside protection is getting stronger and stronger. In 2019, when he was just engaged in the cable protection work, he had to deal with more than 10 early warning every day, and often encountered fishermen who refused to cooperate. The crew can understand and cooperate.

"This year, there are 26 Zhoushan boat bosses joining the team of obligations at sea and completed professional training." Li Chaogen said happily that the "supervisor" became a "supervisor", and their work was becoming more and more "easy".

Create a cable "Thousand Mile Eyes"

After a circle, our ship began to return. Although we "get", we are particularly happy.

"Today's cruise to the end of Yushan Water, everything returns normally. At present, it has been anchored at the duty point." As soon as the ship stopped, Li Chaogen immediately took out his mobile phone and reported it in the WeChat group in the cable.

It turned out that Li Chaogen and the crew were not "single soldiers." In the Hideki Cable Monitoring Hall near the Zhoushan Ben Island, which is nearly 100 kilometers, members of the team in the seaside monitoring class also guarded the waters day and night.

How to achieve remote monitoring of submarine cables? Shen Zhenyu turned out a high -definition picture of the monitoring hall from the mobile phone to see it. I saw a huge screen, which is the sea chart of the submarine cable of Zhoushan City. Triangle representatives. This is the "integrated comprehensive monitoring of submarine cable integrated monitoring" developed by the State Grid Zhoushan Power Supply Company for the maintenance of submarine cables. "

Shen Zhenyu enlarged the picture, and one of the small triangles of his fingers continued. As long as he moved the mouse to a small triangle, the ship's ship number, speed, contact phone number and other data can be displayed. For those ships that turn off AIS, there are also ways to make them have nowhere to hide. He pointed at a nearly oval yellow area on the picture and said that this is a ship detected by offshore radar.

"When the ship's shipping speed is less than 1.2 knots/h, the system will automatically issue a warning signal. In addition, we will also judge the operating status of the ship based on experience. Once the dangerous target is found, the boss of the boat will leave, or the command will be reminded by the phone, or the command is command The patrol ship rushed to the alarm area to deal with it. "Shen Zhenyu patted Li Chaogen's shoulder and said that although they did not meet many times, they had a lot of telephones and WeChat exchanges.

In the evening, the wind and waves on the sea gradually became bigger, dispeling the sultryness of the day, and we also stepped on the boat and returned. "Before 2012, there were nearly 10 accidents caused by the sea cables caused by the vessels in Zhoushan every year. In the past two years, the anchor damage accidents occurred in addition to the natural disasters such as typhoons. Yuan. "What made Shen Zhenyu was proud of that since 2019, there have been no outac -cable broken accidents in the Yushan waters since 2019. Such changes are the inexhaustible motivation of their mission.
