On a certain date, the first domestically designed and constructed deep-sea drilling vessel, "Dream," was officially commissioned in Guangzhou. President Xi Jinping sent a congratulatory letter, fully affirming the scientific and technological personnel for "leveraging the advantages of the new national system, embodying the spirit of pioneering innovation, unity and collaboration, overcoming difficulties, and striving for the peak, overcoming multiple world-class technical challenges, and fully demonstrating the self-confidence, self-reliance, and mission of Chinese scientific and technological personnel in the new era." He emphasized the need to "make good use of this major scientific and technological facility, enhance marine technological innovation, expand international marine cooperation, and make greater contributions to advancing the Chinese modernization and promoting the building of a community with a shared future for mankind."

The important congratulatory letter from the General Secretary points out the direction for the development of China's deep-sea industry in the new era and provides fundamental guidance. The ocean is the cradle of life, vast and spacious, rich in resources and diversity. Developing the marine economy and building a maritime power are of significant strategic importance for the sustainable development of China's economy and society, and for safeguarding national sovereignty, security, and development interests.

习近平总书记高度重视海洋强国建设，高度重视我国深海事业发展，多次作出重要指示批示。年月，总书记在中国科学院深海科学与工程研究所考察时，仔细听取有关我国深海科学研究和探测情况介绍，兴致勃勃走进深海探测装备展示区察看各种深海深潜高技术装备，拿起采自马里亚纳海沟万米海底的海水样品仔细端详，强调“我国是一个海洋大国，海域面积十分辽阔。一定要向海洋进军，加快建设海洋强国”；年月，总书记致信祝贺“奋斗者”号全海深载人潜水器成功完成万米海试并胜利返航，强调要“继续弘扬科学精神，勇攀深海科技高峰，为加快建设海洋强国、为实现中华民族伟大复兴的中国梦而努力奋斗，为人类认识、保护、开发海洋不断作出新的更大贡献”；年月，总书记来到中国海洋大学三亚海洋研究院，连线“深海一号”作业平台，强调“要推动海洋科技实现高水平自立自强，加强原创性、引领性科技攻关，把装备制造牢牢抓在自己手里”……总书记的重要论述和亲切关怀，为我国海洋事业发展注入了强大动力、提供了科学指引。

Since the new era, under the strong leadership of the Party Central Committee with Comrade Xi Jinping at its core, China's marine affairs have achieved significant accomplishments. Major projects for the development and protection of marine resources have been steadily advanced, with key marine equipment continuously emerging. The first deep-sea drilling vessel successfully completed its trial voyage, offshore oil and gas exploration and development have achieved a leap in water depth, the "Blue Whale" successfully tested combustible ice extraction in the South China Sea, the marine economy has achieved remarkable results in transitioning towards quality and efficiency, and the marine ecological security barrier has been further strengthened.

From the "Jiaolong" to the "Deep Sea Warrior" and then to the "Striver," from "deep diving" to "deep drilling" and then to "deep networks," China's deep-sea endeavors have flourished, achieving remarkable accomplishments that have captured global attention. The "Dream" ocean drilling vessel, with a gross tonnage of approximately, displacement of tons, a range of nautical miles, and a maximum drilling depth of meters, possesses the capability to operate in any sea area worldwide. The successful sea trial and official commissioning of the "Dream" vessel mark a significant step forward for China in deep-sea entry, exploration, and development, and represent another major achievement in the construction of a maritime and technological powerhouse.

Exploring the mysteries of the deep sea and advancing into the depths of the Earth are common dreams of all humanity. In recent years, continuous innovation in deep-sea technology and leapfrog development in deep-sea science have created conditions for humans to further understand and develop the ocean. The 20th National Congress of the Communist Party of China made an important deployment to "develop marine economy, protect marine ecological environment, and accelerate the construction of a maritime power." The Third Plenary Session of the 20th Central Committee of the Communist Party of China proposed major tasks to improve the system and mechanisms for promoting marine economic development, establish and improve marine resource development and protection systems, and enhance mechanisms for safeguarding maritime rights and interests.

We must deeply study and comprehend Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era, especially Xi Jinping's important expositions on building a strong maritime country, fully implement the important deployments of the 20th National Congress of the Communist Party of China and the Third Plenary Session of the 20th Central Committee, accelerate original and leading technological breakthroughs, promote the transformation of scientific and technological achievements, and deepen international exchanges and cooperation. We must adhere to and strengthen the Party's comprehensive leadership, carefully summarize the valuable experience from the construction of the "Dream" vessel, leverage the advantages of the new national system, promote excellent work styles, unite all forces, and continuously advance the development of deep-sea endeavors to a new level.
