Yesterday, the journalist learned from the Lianyungang Center of Taihu Laboratory of Deepsea Technological Science that the world's first experimental vessel with deep sea green intelligent technology was assembled in CSSC Chengxi Shipyard Co., Ltd. In the future, the experimental vessel with deep-sea and far-sea green intelligent technology will also undergo processes such as launching, dock outfitting, mooring testing and navigation testing and will be completed and delivered for use in early 2025. At that time, the ship will serve as a testing and verification platform for domestic marine equipments to fully assess the performance, function, efficiency and reliability of marine equipments under actual sea conditions and actual ship application conditions, promote the green, intelligent, and high-end development of marine equipments in China, bridge the "last mile" of independent research and domestic application, and inject innovative vitality into the development of new quality productivity in the marine equipment industry.

The experimental vessel with deep-sea and far-sea green intelligent technology is jointly invested by Taihu Laboratory of Deepsea Technological Science and Lianyungang Center of Taihu Laboratory of Deepsea Technological Science, co-developed by 702, 604, 704, 711 and 712 institutes of China Shipbuilding Group, built by CSSC Chengxi Shipyard Co., Ltd., and classified into China Classification Society. The port of registry is Lianyungang. Building of the vessel started on October 18, 2023, with a total length of 110.8 meters, a width of 20.0 meters, a displacement of about 7000 tons, a designed speed of 15 knots, a range of 10000 nautical miles, and a capacity of 80 people. It is navigable worldwide in unlimited navigation areas.

As a "mobile offshore laboratory", the ship is the core offshore experimental equipment in the "hole-pool-lake-sea" experiment and research system of Taihu Laboratory. In the future, the ship will undertake tasks such as offshore testing, verification and demonstration application of intelligent devices, equipment and systems, demonstration and verification of key technologies for deep-sea and far-sea equipments, and support for deep-sea and far-sea scientific testing operations.

According to the person in charge of the ship manufacturing enterprise from CSSC Chengxi Shipyard Co., Ltd., the total section construction method was adopted to build the experimental vessel with deep-sea and far-sea green intelligent technology. A total of 86 hull segments and 7 hull sections were assembled in the order from stern to bow and from bottom to top. In addition to the overall assembly of the ship, all professional outfitting and interior decoration, as well as the installation of scientific research equipment, were to be completed at the same time.

In order to better carry out the test, the first domestic intelligent medium speed machine and the intelligent information system MarineNet (name of the system) independently developed by Taihu Laboratory was applied in the shipbuilding, which could realize intelligent navigation, energy efficiency optimization, health management, safety management and control, ship-shore collaboration and other intelligent functions, and support the "acquisition, storage, calculation, management and application" of the ship's whole life cycle data on human-machine-material.

Meanwhile, the ship also adopts full electric propulsion, dual propellers and dual rudders, bow/stern dual thrusters, full speed anti roll fins, and DP-2 level dynamic positioning system, which has the characteristics of good navigability, good maneuverability and high reliability. Plus, the ship is equipped with the most advanced and complete domestic sea trial operation support system, underwater acoustic system, lunar pool system, lifting fin system, multidisciplinary and multifunctional laboratory as well as highly integrated data center, which can ensure the efficient conduct of more sea trials.
