中船集团第七〇八研究所首席专家、“梦想”号总设计师：“梦想”号大洋钻探船——挺进地球深部的“国之重器”

Core Viewpoint - The successful launch of China's first independently designed and built deep-sea drilling vessel "Dream" marks a significant advancement in the country's deep-sea exploration technology and capabilities, breaking multiple world records and establishing a new benchmark in the industry [1][7]. Group 1: Vessel Specifications and Capabilities - "Dream" has a maximum drilling depth capability of 11,000 meters, making it the only deep-sea drilling vessel globally capable of penetrating the Mohorovičić discontinuity (Moho) [3][4]. - The vessel's total length is 179.8 meters, width is 32.8 meters, and height is 81.2 meters, equivalent to a 25-story building, with a maximum variable load of 15,000 tons [3][4]. - It can operate for 120 days without resupply and withstand super typhoons of up to level 16, improving operational efficiency by 60% compared to foreign counterparts [4][5]. Group 2: Technological Innovations - "Dream" features a modular design that integrates functions for ocean scientific drilling, deep-sea oil and gas exploration, and natural gas hydrate investigation, which is a significant challenge globally [1][4]. - The vessel includes the world's first hydraulic lifting drilling machine that combines oil and gas exploration with core drilling capabilities, enhancing drilling efficiency and hard rock penetration [4][5]. - It houses a comprehensive onboard laboratory with nine experimental functions, making it the largest and most versatile "mobile laboratory" at sea, with nearly 40% more space than foreign vessels [4][5]. Group 3: Strategic Importance - The construction of "Dream" breaks the long-standing foreign monopoly in the deep-sea drilling vessel sector, positioning China as a leader in this field [5][6]. - The vessel's capabilities allow China to independently organize ocean drilling expeditions, transitioning from a participant to a leader in global ocean exploration [7]. - "Dream" is expected to significantly contribute to the understanding of Earth's internal structure and support global scientific endeavors to explore the unknown [7].
