Core Viewpoint - The article emphasizes the importance of energy transformation as a strategic precursor to productivity advancement, highlighting the need to cultivate energy technologies and related industries as new growth points for industrial upgrading in China [2]. Group 1: Deepwater Oil and Gas Exploration - In the past decade, nearly 60% of the 100 largest newly discovered oil and gas fields globally are deepwater fields [4]. - "Deep Sea One" is China's first complete large-scale deepwater project, with a total weight exceeding 50,000 tons and a height equivalent to a 40-story building [8]. - The "Deep Sea One" gas field has proven natural gas reserves exceeding 150 billion cubic meters, with the first phase of development targeting 103.1 billion cubic meters at an average water depth of 1,500 meters [7][12]. Group 2: Technological Innovations - The "Deep Sea One" energy station is the world's first 100,000-ton ultra-deepwater semi-submersible production and storage platform, utilizing three world-first technologies and 13 domestic-first technologies [10]. - All equipment for "Deep Sea One" is custom-designed for the extreme conditions of deepwater environments, ensuring decades of maintenance-free operation and a fatigue life of over 150 years [10]. Group 3: Energy Transition and Hydrogen Production - Hydrogen energy is recognized as the "ultimate energy of the 21st century," playing a crucial role in the global energy structure transformation [14]. - The first factory-scale seawater direct hydrogen production research project in China began trial operations in Qingdao, Shandong, in December 2024, marking a significant step in developing marine energy productivity [14].
