Essay on the island building artifact Tiankun, when will the island building artifact Tiankun be lau

The island-building artifact "Tian Kun", which is prohibited from export by the Ministry of Commerce, has passed the "big test" and is about to be transformed into a real "mapper". According to Xinhua News Agency, at 12:30 on the same day, after nearly three months of dredging and rock dredging tests, Asia's largest heavy-duty self-propelled cutter suction ship "Tian Kun", invested and built by CCCC Tianjin Waterway Bureau, successfully returned to the shipyard, marking the completion of all tests and officially having production capacity.

The "Tiankun" is 140 meters long, 140 meters wide, 35 meters deep, with a power of 25,843 kilowatts, a design of 6,000 cubic meters per hour of dredging, and a rated power of 6,600 kilowatts for the reamer. Its dredging capacity surpasses that of the largest cutter suction dredger in Asia, "Tianjing", which is also invested by CCCC Tianjin Waterway Bureau

During the test, the performance of the key construction equipment such as the excavation system, conveying system and intelligent dredging system of the "Tiankun" successfully passed the test of actual construction, and all the test technical indicators met or exceeded the design standards.

Heavy dredging is a high-tech, capital-intensive national important basic equipment. Whether it is the excavation of Tianjin Port, the world's largest artificial deep-water port, or the dredging of the deep-water channel of the Yangtze River, it is inseparable from the figure of heavy dredgers. Only a few countries in the world, such as the Netherlands and Belgium, have mastered the core technology of independent design and construction, and heavy dredgers are mostly managed as national strategic equipment.

The first self-propelled cutter suction dredger in Asia, the first self-propelled cutter suction dredger independently developed and built by China, was successfully launched not long ago and is about to go to sea for sea trials. Its birth means that the "big country heavy weapon" in the field of dredging is firmly in the hands of the Chinese themselves and is no longer subject to others. The "Tiankun" will surpass the "Tianjing", which is currently in service in Asia, and become a key weapon for the new generation of China to build China's maritime frontier and jointly build the Chinese dream.

At present, the annual dredging capacity of China's dredging enterprises has exceeded 1 billion cubic meters, and it has become the world's largest dredging country. The "Tian Kun", which was newly launched by the Tianjin Navigation Bureau, is the sister ship of the "Sky Whale", which has taken a big step forward in independent innovation. It is the first heavy-duty self-propelled cutter suction dredger designed and built in China with completely independent intellectual property rights.

The 'Tian Kun' marks that China has been able to independently design and build a new generation of heavy-duty self-propelled cutter suction dredger, and has achieved a breakthrough in the key technology of this ship type. Fei Long, a master of ship design and deputy chief engineer of the 708th Research Institute of China Shipbuilding Industry Corporation, said. China has become one of the few countries in the world that can use its own equipment and technology to dredge waterways and reclaim land.

On November 2, it was learned from CCCC Tianjin Waterway Bureau (hereinafter referred to as Tianhang Bureau) that the 6600kw cutter power heavy-duty self-propelled cutter suction ship "Tiankun" invested and jointly designed by the company and built by Shanghai Zhenhua Qidong Shipyard will be launched in Qidong, Jiangsu Province on November 3.

With a length of 140 meters, a width of 140 meters and a maximum excavation depth of 35 meters, the Tiankun can transport a mixture of sand, rock and seawater at speeds of up to 15,000 meters at speeds of up to 6,000 cubic meters per hour. Not only that, the ship is equipped with 4 different types of reamers: general-purpose, clay, rock digging and heavy rock digging, which can excavate rocks with higher seabed hardness than the big brother "Sky Whale".

It is worth noting that after the "Tian Kun" is launched, with its long-distance transportation capacity of up to 15,000 meters, it will become an important national weapon in the construction of China's maritime frontier. Regarding the work efficiency of the "Tian Kun", Kong Fanzhen, the hull engineer of the ship's supervision group, gave a vivid explanation to The Paper: "If the Tian Kun is used to excavate and fill a Water Cube, it will only take six and a half days at the maximum power.

In addition, the staff of the Tianjin Navigation Bureau said that the successful launch of the "Tian Kun" will mark the phased results of the construction of the most advanced heavy-duty self-propelled cutter suction dredger in Asia, which was independently designed and built by China, and then the ship will enter the stage of outfitting and equipment and system commissioning.

As the world's largest dredging country, China's dredging ships have gone through the tortuous development path of whole ship import, foreign design and domestic construction, and domestic independent design and construction, and have experienced a tortuous process from scratch, from small to large, and from large to strong. The "Tian Kun", which is about to be launched, not only represents the construction level of China's dredging ships, but also marks that China has entered the ranks of dredging powers.

Kong Fanzhen, a hull engineer of the ship's supervision team, once used a vivid analogy: "It only takes six and a half days to excavate and fill a 'water cube'. ”

The Tianjing, Asia's largest cutter suction dredger, can discharge a mixture of sea sand and seawater to a distance of up to 6,000 meters at a speed of 4,500 cubic meters per hour when performing reclamation operations.

The performance of the "Tian Kun" has been surpassed in an all-round way, and it can transport sea sand, rocks and seawater mixtures to a distance of up to 15,000 meters at a speed of 6,000 cubic meters per hour, becoming a national important weapon in the construction of China's maritime frontier.

Not only that, the ship is equipped with four different types of reamers: general-purpose, clay, rock digging and heavy rock digging, which can excavate rocks with higher hardness on the seabed than the "Sky Whale".

Model of the Tian Kun.

Such a strong ability comes from the unremitting efforts of scientific research and design workers. The 708 Institute, founded in 1950, is one of them.

According to public information, it is the largest national engineering research center for ship design technology in China, with nearly 700 employees and more than 600 professional and technical personnel, covering more than 20 majors.

How awesome are they? Perhaps we can get a glimpse of it from one example after another. They designed the 1,000-ton maritime surveillance ship "China Maritime Surveillance 1001," which was launched just in January on the "Xiangyanghong 01,000,000," which is currently carrying out China's first comprehensive global marine scientific expedition.

My kingdom is getting worse and worse.

The Tiankun is the largest heavy-duty self-propelled cutter suction ship in Asia, designed by the 78th Research Institute of China State Shipbuilding Corporation and built by Shanghai Zhenhua Heavy Industry Group Qidong Company.

On the morning of November 3, 2017, Asia's largest and most advanced cutter suction dredger "Tiankun", independently designed and built by China, was successfully launched in Qidong, Jiangsu. It marks the further upgrading of China's dredging equipment R&D and construction capabilities, which has been at the world's advanced level. [2]

According to the data provided by the "Tianjin Navigation Bureau", the "Tiankun" ship is 140 meters long, 140 meters wide, 35 meters deep, 25,843 kilowatts, 6,000 cubic meters per hour of dredging, and 6,600 kilowatts of reamer power.

According to reports, the "Tian Kun" mud pump has a transmission power of 17,000 kilowatts, which is the highest power configuration in the world, and its long-distance transmission capacity is 15,000 meters, which is the largest in the world.

With the rapid development of the world and domestic economy, the entire dredging industry is facing more and more arduous challenges, hard soil, long conveying distance, poor working conditions make the traditional cutter suction ship can not be fully adapted. In the past, the projects that could be completed by bombing reefs had to be transferred to heavy cutter suction ships due to the protection of the ecological environment and the remoteness of the islands and reefs.

In China, only the Tianjin Navigation Bureau has a "Sky Whale" self-propelled cutter suction dredger. Since the ship was put into operation in 2011, it has shown great power in the construction of many key projects, especially in the excavation of rocks and long row distance dredging projects, which has played an excellent economic and social benefit, and the construction of offshore islands and reefs has become famous.

The design and construction of the new generation of heavy-duty self-propelled cutter suction dredger "Tiankun" was designed by the 78th Research Institute of China State Shipbuilding Corporation, and the construction of Shanghai Zhenhua Heavy Industry Group Qidong Company started in early 2016.
