On December 27, 2023, it was reported in China that China's first independently designed and built ocean drilling ship "Dream" successfully completed its first sea trial in the waters of the Pearl River Estuary, marking a new breakthrough in the field of deep-sea scientific research in China.
It is reported that the trial voyage covered the commissioning and verification of 19 key marine systems such as ship propulsion system and life-saving anchorage, and completed the relevant projects of forensics in accordance with international regulations. During the sea trial, the "Dream" successfully passed the Lingdingyang Bridge, demonstrating its unique advantages of small tonnage, multi-functional and modular design. This design feature allows the Dream to accommodate most of the world's terminals, while reducing its construction and operating costs by more than 40% compared to similar international drillships.
2023 Annual Inventory As the "crown" project in the field of marine science and technology, ocean drilling has extremely high scientific research and resource development value on a global scale. With a total tonnage of about 33,000 tons, a cruising range of 15,000 nautical miles, and a self-sustaining power of 120 days, the "Dream" has the ability to operate in unlimited navigation areas and drill 11,000 meters in sea areas around the world.
In addition, the "Dream" has made a number of breakthroughs in technology, including more than 10 key technologies such as comprehensive optimization of hydrodynamic performance and operation system module layout. The ship innovation integrates two major control systems, eight types of operating systems such as core acquisition and more than 30 subsystems, which provides important support for China's deep-sea scientific research and resource exploration. This successful first trial voyage is not only a demonstration of China's marine science and technology strength, but also lays a solid foundation for future scientific research and exploration in the deep-sea field.
