Tian Kun Hao 1

Tiankun, dubbed by designers as the magic island maker is the largest and most advanced cutter-suction dredger in Asia. Tiankun, developed by the Tianjin Dredging Co., can dredge 6,000 cubic meters per hour, dig as deep as 35 meters under the sea floor, and pump sand and silt into the vessel. It can then blow the sand and silt out as far as 15,000 meters away.

The dredging ship known as the "artifact making island" has greatly enhanced China's reclamation and land reclamation, waterway dredging and port construction and other areas of ability. It is the Chinese shipbuilding industry aiming at the frontier of science and technology in the world of high technology and heavy equipment manufacturing Another milestone in high integration. Depending on the geological conditions, the vessel can be equipped with four different types of reamers: general purpose, clay, rock-digging and heavy-duty rock-digging, capable of excavating rocks with unilateral compressive strength of 50 MPa.

In the late 1990s, China was significantly dependent on foreign dredging technologies, Kang said, saying it is unbelievable that the country can now make world-leading dredging vessels itself. According to him, overseas engineering projects will be the major focus of Chinese dredgers. Only machines like Tiankun are able to finish port-construction tasks in places like Africa with extremely hard rock formations.

Tiankun, a Chinese-made dredging vessel and the largest of its kind in Asia, will reach out to the world for broader application, Kang Xuezeng, president of a dredging company under China Communication Construction Company, said 01 December 2017. The dredging company has grown into the largest in the world.

"Tian Kun", the largest and most advanced self-propelled cutter-suction dredger, was developed and designed by the 708th Research Institute of China State Shipbuilding Corporation. China launched the 140-meter-long cutter-suction dredger in Qidong, East China's Jiangsu Province on 03 November 2017 - the largest and most advanced of its kind in Asia. With a cutter power of 6,600 kilowatts, the Tiankun can excavate 6,000 cubic meters an hour at a maximum depth of 35 meters. The Tiankun is a key project of the Ministry of Industry and Information Technology, with investment and designs from Tianjin Dedging Co. Ltd under China Communications Construction Co. Ltd (CCCC).

According to CCCC, Tiankun leads the list of similar vessels in the world in terms of distance of delivery and other aspects. The all-electric vessel is equipped with a dual positioning system and unlimited global navigation. The Tiankun's advanced systems allow it to carry out unmanned dredging and monitoring operations in ports, in coastal waters, or carry out deep-sea operations.

Construction of the Tiankun began in December 2015 in Qidong, and was expected to go into operation in June 2018. CCCC is the world's largest dredging enterprise and has more than 30 dredgers, including Asia's current largest, the Tianjing.

China seems to be telling rival claimants that China is in the South China Sea to stay and may build more artificial islands with military installations on them to protect its claims. Dredgers stir up plumes of sand and silt that damage coral tissue and block sunlight from organisms such as reef-building corals which cannot survive without it.

In 2009, for example, China Merchants Heavy Industry (Shenzhen) Vo. Ltd built a self-propelled dredger for Tianjin Dredging Co. (subsidiary of China Communication Construction Company, CCCC), designed by Vosta LMG BV, the Tian Jing Hao. Since 2013 China had been dredging sand, gravel, and silt in the South China Sea and depositing it onto rocks, reefs, and sandbars to create artificial islands. Chinese military and construction teams followed up by building airstrips that can accommodate fighter planes and placing hangers, radar, and anti-aircraft guns on the islands.

Prior to this, there was only one self-propelled cutter and steamer in China. In 2006, Tian Hang succeeded in building China's first modern large cutter suction dredger, which had completely independent intellectual property rights, completely breaking the technical monopoly of foreign dredgers. The Tian Jing Hao was so far the most powerful dredge, however China has a new dredger 1.3 times more powerful than its predecessor.

"Tian Kun" was China's first self-designed large self-propelled cutter suction dredger, the maximum excavation depth of 35 meters, the total installed power of 25843 kilowatts, dredging 6000 cubic meters per hour, nominal cutter power of 6600 kilowatt.

The "Tian Kun" is equipped with the most advanced automatic control system in the world and has the capability of navigating and loading in the world's unlimited navigation zones, enabling automatic dredging, monitoring and unmanned operation, which will greatly improve the work efficiency and is suitable for Coastal and deep-sea port channel dredging and other projects.

The three-cable positioning system and the sighting technology lead the technology of flexible steel pile trolley system with high technical standard and full ship layout. Second, the equipment level is high, equipped with the most powerful excavation system in Asia, the maximum power delivery system and the most advanced automatic control system in the world. The active pneumatic vibration damping device is installed on the connection between the superstructure of the ship and the main hull, which can effectively reduce and isolate the influence of low-frequency vibration on the superstructure during the construction of the ship, ensure the living comfort of the crew and the safety of the equipment.
