Mastering the technology for manufacturing self-floating deep-sea seismic measurement systems to serve the marine economy.

A research team from the Institute of Automation and Environment, Vietnam Union of Science and Technology Associations, has just completed a self-floating ocean floor seismic measurement system and related subsystems, meeting the requirements for monitoring and ensuring safety for marine economic activities, while also mastering domestic manufacturing technology.

This is the result of the project "Research, design, and fabrication of a self-floating ocean floor seismometer for marine economic development," under the Physics Development Program for the period 2021-2025, led by Prof. Dr. Pham Ngoc Ho.

The research team has completed the design, fabrication, and testing of a self-floating seabed seismometer system, comprising multiple hardware, mechanical, and software subsystems suitable for the practical conditions of Vietnam.

The developed system includes a self-floating deep-sea seismometer, an integrated module with three types of sensors and related electronic components, device control software, and central station operation control software. Simultaneously, the team developed a set of user manuals, operation and maintenance guides, system test reports, and product design and integration documentation. All products were evaluated and found to meet the registered objectives.

According to the report, the need for seismic monitoring in marine and coastal areas is becoming increasingly urgent to serve disaster warning, monitor tectonic activity, ensure the safety of socio-economic infrastructure, and support marine economic development activities. However, modern seabed seismic measurement systems worldwide are very expensive. Therefore, the initial research and development of modern ocean floor seismic measurement equipment, mastering the technology including hardware, mechanics, and software suitable for Vietnam's specific conditions, is of paramount importance and represents the main contribution of this project.

The research process also yielded significant contributions. Economically, the self-floating seabed seismic measurement system and its subsystems, developed within the framework of this project, offer functions that bring economic, social, and environmental benefits when put into practical application. Specifically, these include: automation of seismic measurement and other parameters in the harsh underwater environment; and automatic, near-real-time updates of measured parameters. Furthermore, the system is domestically produced, not imported from abroad, thus contributing to significant budget savings.

From a societal perspective, this project makes a significant contribution to proactively ensuring the self-construction of a seabed seismic measurement system, minimizing manual labor performed by humans in deep-water environments and ensuring the safety of lives and property during seismic surveys. Furthermore, because the equipment is researched and manufactured domestically, it also contributes positively to the protection of secrets in national security, defense, and the maritime economy.
