Marine Accident Analysis Center (MAAC)
This center contributes to the causes investigation of marine accidents by analyzing information promptly in close collaboration with the Japan Transportation Safety Board (JTSB), the Maritime Bureau, and other organizations in the Ministry of Land, Infrastructure, Transport and Tourism. For severe accidents, this center further contributes by drawing up preventive measures by reproducing accident situations using the Bridge Simulator for Navigational Risk Research, Actual Sea Model Basin, and structural analysis tools.
Center for International Cooperation
This center strives to support the development and revision of international regulations and standards managed by the International Maritime Organization (IMO), the International Atomic Energy Agency (IAEA), the International Organization for Standardization (ISO), and other international organizations.
This project team is promoting the development and social implementation of digital twin technology for ship hulls, digital twin technology for marine main engines, digital twin technology for ship operations, digital platform technology for ship design, and digital platform technology for ship construction, which will be key technologies in realizing the digital transformation of the maritime industry.
The IMO's GHG reduction target is to improve overall international shipping fuel efficiency by at least 40% by 2030, and by 2050, total GHG emissions must be reduced by at least 50%. This project team will develop GHG reduction technologies from the viewpoints of hydrodynamics, alternative fuels, and engine efficiency. This project team developed a tool for estimating total GHG emissions based on demand forecasts for maritime logistics to examine strategies. By developing business models, this project team is progressing the social implementation of its research results.
The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) aims to realize autonomous ships by 2025. To contribute to the aim, NMRI has established this project team to ensure safety evaluation technologies for autonomous ships. This project team is developing a new fast-time simulation system and a new navigation-risk simulator to evaluate the safety of autonomous ships. This project team's crucial missions are automatic berthing/leaving technology developments and machine-vision technology for vessels. This project team aims to implement the developed technologies in practice and to realize autonomous ships by 2025. This project team thinks it is essential to couple a farsighted strategy with an appropriate business model.
The implementation of the Renewable Energy and Marine Use Law has created an environment conducive to the widespread use of offshore wind power. To promote the use of offshore wind power, this project team proposes a concept of floating offshore wind power generation in high-wind-speed waters. This project team is also promoting the construction of offshore wind farms by suggesting a business model for offshore wind power.
Next-Generation Unmanned Ocean Vehicle PT
As a next-generation mobile platform for ocean utilization and development, the utilization of unmanned ocean vehicles such as AUVs (Autonomous Underwater Vehicles) is advancing worldwide. In Japan, to support the related research and development, an AUV Strategy Project Team overseeing unmanned ocean vehicle strategies has been established within the Advisory Council of the Integrated Maritime Policy Headquarters, the Japanese government. This project team aims to support such national efforts at the field level and to contribute to society by carrying out leading research and development to be at the forefront globally.
Safety Operation Office of Dynamic Positioning System
The use of vessels equipped with Dynamic Positioning (DP) systems, such as SEP, is expected to increase in the future for the development of renewable energy sources, such as offshore wind power generation, as well as for the exploration of marine resources like seabed minerals and methane hydrates in Japan.
Therefore, this office will contribute to the safe operation of the DP systems by collecting and analyzing information on safety, environmental protection, and accidents. Additionally, this office will handle emergencies unique to DP vessels with the DP simulator installed at NMRI.
Cloud Platform Operations Office
In order to enhance the competitiveness of the Japanese maritime/offshore sector, open innovation in the maritime/offshore domain must be accelerated. NMRI is operating and developing its "NMRI Cloud" platform to fulfill these needs. The NMRI Cloud offers the industry a remarkably practical and expandable solution in the domain by leveraging cloud computing technology and experimental data gathered from the NMRI's facilities and advanced simulation technology of NMRI.
