2025 International Conference on Ocean Engineering and Environmental Resources(OEER 2025) was grandly held in the picturesque North Sea this year, becoming a major event in the field of marine science this year. This conference has attracted experts, scholars, and industry leaders from around the world to gather together and discuss important issues related to ocean engineering and environmental resources. As one of the important coastal cities in China, Beihai has added a unique charm to this conference with its unique geographical location and abundant natural resources. OEER 2025, with the theme of ""Innovation Leads the Future, Technology Protects the Ocean"", has set up multiple sub venues covering a wide range of topics from marine ecological protection to sustainable development. During the conference, numerous experts and scholars shared their latest research achievements in the fields of ocean energy development, environmental protection technology, marine ecological restoration, and the impact of climate change. Especially the discussion on emerging ocean engineering technologies has attracted widespread attention from attendees. These technologies not only have the potential to improve the safety and efficiency of offshore operations, but also aim to reduce their impact on the marine environment. In addition, the conference has arranged a series of interactive events, including a forum for young scientists and specialized seminars, aimed at encouraging the younger generation to actively participate in marine scientific research and promoting interdisciplinary and cross-border communication and cooperation. Through these platforms, participants can not only showcase their research achievements, but also gain a deeper understanding of the latest developments in marine engineering and environmental resource management worldwide. The successful hosting of OEER 2025 not only promotes academic exchanges and technological cooperation in the fields of marine engineering and environmental resources internationally, but also provides new ideas and solutions for addressing current issues such as marine pollution and resource depletion. With the successful conclusion of the conference, we look forward to these valuable knowledge and experience being widely applied in future practice, jointly promoting the sustainable development of the global ocean industry and protecting our blue planet.
