Japan's ship building researches and technologies yield applications in many industries

Ships have been used by humankind since ancient times as a means of transportation. Ship building technologies have advanced and evolved over time as advanced in science and technology. In recent years, Japan, as the world's ship building superpower, has overwhelmed all others in both design and technology, and has contributed a great deal to realize today’s safe and efficient maritime transportation and industrial development through the diverse applications of its technological developments in other industries. Such applications include the use of analytical theories, computer simulations at sites where all kinds of manufactured products are made, and the important contributions that have been made by product reliability tests to the safety and quality of manufactured goods. There are great expectations for the ways these time-honored technologies will be applied to new frontier fields in a future.

Marine Safety
Achieving ocean safety by developing advanced navigation systems and technologies for high durability hulls

Ship safety is derived from two main researches: the strength of the hull itself and the technologies related to the navigation system. In our department, to ensure the safety and structural strength of a ship, safety evaluation techniques using the latest technologies, such as FEM analysis, CFD calculations, potential theories, and scaled model experiments are researched. Corrosion avoidance routing simulations and whole ship structural analysis directly linked to ships’ life cycle assessment conducted through collaborative projects sponsored by the government, ship building and maritime companies. The advanced level of such research projects of our department has been demonstrated.

Ocean Energy
Research into underdeveloped ocean energy

The ocean, which covers nearly 70% of the earth's surface, is receiving a great deal of attention as a valuable source of energy. Hydrogen can be extracted by floating structures as long as 2 km in length on the sea, and performing electrolysis using energy obtained by wind many generators installed on them. Students will work on an experiment about how to carry the hydrogen to the shore in the same way that crude tankers carry oil. The ocean float would be navigated by massive sails, thus allowing the creation of clean, low-cost energy. Also, many futuristic energy extraction trials are underway, including research on ships that would convert wave energy into propulsion energy.

Development of new propulsion systems and underwater environment monitoring robot

Robots that walk on two legs are developed as well known, on the other hand, underwater robots are expected to attract a great deal of research and be considered to yield significant applications in the future. In this department, students will several works under joint industry-academia projects to conduct research and development on under water robots that automatically monitor the ocean environment, auto navigated robots for examining ocean resources, and robots for conducting underwater operations. The development of a system that can retain its position in highly unstable currents and propulsion systems that enable self-guided motion and turning are receiving extensive attention from all fields. As mathematical analytical simulation technologies are developed and the aggregation of complex technologies is promoted, the range of applications for these developments is likely to expand.

Japan fulfills reputation as a superpower of ocean engineering through the international collaborations and contributions

Japan's position as an ocean superpower is attracting a lot of attention from around the world. Japan's ship building technologies, operation and navigation simulation technologies, and technologies for analyzing the life cycle value in their trans-services are highly acclaimed not only by the developed nations, but also by the most prominent of the developing nations. Many foreign students and researchers engage in diverse research projects while taking this course. Our world-class professors are well known worldwide, as is the content of their research, accelerating our pace of internationalization. Our researchers are constantly expanding their technological exchanges by collaborating with researchers from many countries, including the US and Europe as well as Asia, Africa, and Central and South America.

Challenging to underdeveloped frontier areas stimulates research interest

Research fields of naval architecture and ocean engineering have already attracted the attention of many researchers. Some may therefore wonder if the unexplored areas in this field are dwindling. In reality, the opposite is true. An extraordinary number of research fields related to our field have yet not to be scientifically explored. For researchers, this is a field in which there is still a great challenging. It is also one in which students can carve out a niche based on their own ideas and theories. They can take major steps forward by research day by day with distinguished predecessors. This is a major advantage and attraction of our department.
