The PhD in Ocean Engineering at Yokohama National University is part of the Doctoral Program within the Department of Mechanical Engineering, Materials Science, and Ocean Engineering in the Graduate School of Engineering Science. In this program, doctoral candidates pursue advanced research and development related to naval architecture, marine structures, ocean‑space systems design, and the use of marine environments for energy and infrastructure, building on fundamental physical analyses from micro to macro levels. Research areas may include ship‑ and offshore structure design, ocean system dynamics, floating structures and renewable energy from marine environments, coastal engineering, and multidisciplinary ocean engineering topics. Students undertake independent research under faculty supervision, complete required coursework, and must prepare and defend a doctoral thesis (Doctor of Engineering) that contributes original insights to the field. The program aims to cultivate researchers and leaders whose work can address technological challenges in marine and ocean environments on both global and industrial levels.

NOTE: The university may have additional program-specific eligibility requirements.
It is recommended to verify these on the official university website.
