10th International OTEC Symposium

The International OTEC Symposia have taken place since 2013, each time hosted by a separate organizing committee in each host country. The Ocean Thermal Energy Association (OTEA) guides the overall organization of these events from 2020.

The Ocean Thermal Energy Association is pleased to announce that the 10th International OTEC Symposium will take place December 4-5, 2024 in Rio de Janeiro, Brazil.

The Universidade Federal do Rio de Janeiro in cooperation with other Brazilian Universities and institutions will host the event with support from SOBENA (Brazilian Society of Naval Engineering).

The venue for this year’s event will be the Windsor Florida Hotel.

More information to follow soon.

Has experience in Material and Metallurgical Engineering, focusing on Ceramics, acting on the following subjects: synthetic and natural quartz, saxs, x-ray topography and digital radiography.

Prof. Segen Farid Estefen – General Director – National Institute for Ocean Research (INPO)

Graduation at Engenharia Civil from Universidade Federal de Juiz de Fora (1973), master’s at Naval and Oceanic Engineering from Universidade Federal do Rio de Janeiro (1976) and doctorate at Engenharia Civil from Imperial College London – South Kensington Campus (1984). He is currently member advisory committee ooae division- asme at Ocean Offshore And Arctic Engineering Division. Has experience in Naval and Oceanic Engineering, focusing on Naval and Oceanic Structures, acting on the following subjects: dutos submarinos, pipelines, sandwich pipes, risers and ocean renewable energy devices.

Prof. Kazuo Nishimoto – Professor at University of São Paulo

Holds an undergraduate degree in Naval and Ocean Engineering from the University of São Paulo (1979), a master’s degree in Naval and Ocean Engineering from Yokohama National University (1982), and a doctorate in Naval and Ocean Engineering from the University of Tokyo (1985). Currently, he is a full professor at the University of São Paulo. His specialization is in Naval and Ocean Engineering, with an emphasis on Hydrodynamics and the Design of Ships and Ocean Systems. However, his work has increasingly focused on integrating various engineering knowledge and basic sciences as the founder of the Numerical Test Tank (TPN), primarily in the areas of Numerical Simulation of Ocean Systems Dynamics and the Development of New Ocean Systems. Recently, he established a new research center under the FAPESP/CPA program—the Offshore Technology Innovation Centre (OTIC) in collaboration with Shell, with a primary focus on developing future ocean systems, emphasizing decarbonization and digital transformation.
