In March 2023, the “Haiji No. 1” Lufeng 15-1 DPP jacket digital twin health management system—developed and constructed independently by Dalian Kemaier Marine Technology Co., Ltd.—underwent a field demonstration of its system functions and a project briefing. Following on-site evaluation and deliberation, the expert panel concluded that the system’s trial-operation performance met the anticipated requirements, with all key performance indicators for both the monitoring system and the digital twin system satisfying the predefined specifications. The panel unanimously approved the system’s acceptance, which was subsequently confirmed in May 2023 through successful certification by the China Classification Society. This milestone marks the official transition of the world’s first deepwater jacket digital twin health management platform into its operational monitoring phase, representing a significant breakthrough for China in the field of deepwater digital twins and underscoring its critical importance for enhancing intelligent risk early warning and full lifecycle operation-and-maintenance management of deep-sea oil and gas equipment. 
The digital twin health management system was developed based on “Haiji No. 1,” Asia’s first 300-meter-class deepwater jacket platform. Leveraging advanced intelligent sensing and digital twin technologies, the system establishes two integrated platforms—one virtual and one physical—to enable comprehensive perception of subsea structures, remote and controllable safety management, and intelligent early warning of safety risks. This solution effectively addresses key operational and maintenance challenges associated with deepwater jacket platforms, enhances O&M management, and optimizes design methodologies, making it one of China’s flagship demonstration projects for the digital and intelligent transformation of offshore oil and gas operations.
A pioneering digital twin software system for jacket platforms has been developed, integrating comprehensive capabilities such as unified data management, monitoring and early warning, inspection and assessment, and digital twin modeling. The development of this system posed significant challenges, requiring the interdisciplinary integration of smart sensing, maritime–land communication, data fusion and mining, and structural integrity management. Since its installation and commissioning in July 2022, the system has successfully acquired data from three typhoons: “Mahan,” “Nesat,” and “Nigeh.”
Moving forward, we will leverage big-data storage technologies and sophisticated algorithms to establish early-warning criteria, thereby enhancing the system’s emergency-response capabilities. By continuously refining and iteratively updating the digital twin database based on accumulated monitoring data, we will steadily elevate the intelligence level of real-time analysis and condition monitoring for jacket platforms. This work will have far-reaching implications for future design optimization of deepwater jacket platforms, the development of design codes, and the localization of relevant software. Going forward, our R&D team will persist in iteratively upgrading the digital-twin-based health-management system and extending its application to newly built deepwater platforms such as Lufeng 12-3 and Liuhua 11-1. We will proactively position ourselves in cutting-edge technologies, contributing to the advancement of digitalization and intelligentization in China’s offshore oil-and-gas equipment.
