「海のフロンティアを拓く岡村健二賞」創設趣意
テクノオーシャン・ネットワーク（TON）
では、岡村健二氏のご遺志を継ぐ事業の一つとして、ご遺族のご芳志をいただき、同氏が所属されていた三菱重工業株式会社のご厚意のもと、2010年に「海のフロンティアを拓く岡村健二賞」を創設いたしました。
故岡村健二氏は、日本の海洋開発について、先行的・共通的技術開発の必要性、重要性を強調され、海洋科学技術センター（現JAMSTEC）の設立および初代理事の一人として機器開発や深海研究の実施に積極的に取り組まれました。
これは国家プロジェクトである有人潜水艇「しんかい2000」や「しんかい6500」の実現につながりました。また、海洋技術の先進国である米国を目標にわが国の海洋工学の向上に腐心され、わが国の海洋関係者に米国の技術レベルとわが国のそれとをしっかり認識することの重要性を常に考えられ、米国で毎年開催される海洋国際コンベンションであるOCEANSやROV International（現Underwater Intervention）等を日本に誘致することを考えておられました。
その夢は、岡村氏が物故された後、ようやく2004年にNOAA長官を基調講演に招いたTechno-Ocean / OCEANS 2004として実現したわけです。また、同氏は、技術者として世界トップクラスの高速ディーゼル機関を開発、完成させたディーゼル機関の国際的権威者でもあります。
このように、技術者として常に新しい技術への挑戦を続け、国際的視野に立ち、先見の明をもたれた岡村健二氏は、海洋立国日本の発展のためにご活躍され、多大なるご貢献をされました。
そこで、TONでは、2010年のTechno-Ocean開催を機に、岡村健二氏の社会的功労を偲び、学術的功績を讃え、「 海のフロンティアを拓く岡村健二賞」を創設し、同氏の遺志を継ぐわが国の若い研究者・技術者に対して、これを贈呈することといたしました。

Kenji Okamura Memorial Award for Pioneering the Ocean Frontier
Founding Statement
The Techno-Ocean Network (TON) established the Kenji Okamura Memorial Award for
Pioneering the Ocean Frontier in 2010. This award is one of a number of projects conducted inaccordance with the wishes of the late Dr. Kenji Okamura with the kind consent of his bereaved
family and through the courtesy of Mitsubishi Heavy Industries Ltd., the company for which heworked for many years.
With respect to Japanese marine development, the Dr. Okamura laid a strong emphasis on thenecessity and importance of pursuing advanced and uniﬁed technological development. Dr.
Okamura was actively involved in developing equipment and conducting deep-sea research as oneof the founding directors of the Japan Marine Science and Technology Center (the forerunnerorganization of the present Japan Agency for Marine-Earth Science and Technology (JAMSTEC)).
His work was closely linked with the achievement of the national projects to develop the manned
deep-sea submergence research vehicles SHINKAI 2000 and SHINKAI 6500 . Dr. Okamura
also made every eﬀort to raise Japan s ocean engineering to a level matching that of the UnitedStates, which possessed the world s most advanced ocean technology. He always considered it
extremely important that those working in ocean-related ﬁelds in Japan had a clear grasp of thetechnological levels in both the US and in Japan, and to this end he paid consideration to attracting
international marine conventions to Japan such as OCEANS and ROV International (the presentUnderwater Intervention), which are held annually in the US. This dream was ﬁnally realized in
2004, after his death, with the holding of Techno-Ocean/OCEANS 2004, to which the President of
the NOAA was invited as a keynote speaker. Furthermore, Dr. Okamura was an acknowledged
international expert on diesel engines who developed and perfected one of the world s top-classhigh-speed diesel engines.
In ways such as these, Dr. Okamura continually rose to the challenge of developing new technology.
He possessed a foresight that rested on a global viewpoint, played an active role in developing Japanas an ocean state, and made numerous contributions to the advance of technical knowledge.
Taking advantage of the opportunity presented by the holding of Techno-Ocean 2010, TON established
the Kenji Okamura Memorial Award for Pioneering the Ocean Frontier in commemoration of Dr.
Okamura s services to society and in celebration of his academic achievements. This award ispresented to young Japanese researchers and engineers who are judged to be working innovatively inthe ocean ﬁeld in accordance with his wishes.

Kenji Okamura ̶ ProﬁleDr. Kenji Okamura was born in Nagaoka City on December 8, 1912. He graduated from theEngineering Department of Tokyo Teikoku University (the present Tokyo University) in 1934 andjoined Mitsubishi Aircraft Company in the same year. In 1964, in line with a change of company
name, he was transferred to Mitsubishi Heavy Industries, Ltd. After holding important posts such
as Technology Management Manager and later Acting Manager at the Head Oﬃce Technology &Innovation Headquarters, he served as an advisor to the Technology & Innovation Headquartersuntil January 1987. From May 1964 he also held several other prominent positions such as Directorof Ryonichi Engineering Co., Ltd., Executive Managing Director of Mitsubishi Kaihatsu KabushikiKaisha, and President and Director of Ryowa Kaiyo Kaihatsu Kabushiki Kaisha. In 1971, he became
the Director of the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) andsubsequently served as an advisor to that organization from 1986. In 1975, he became Chairman ofthe Engineering Committee on Oceanic Resources (ECOR). In 1951, he was awarded a PhD by theNaval Academy for the development of a marine high-performance diesel engine. During his longcareer, he was also honored with a slew of awards including the Medal with Purple Ribbon in 1955,
the First MTS International Award in 1980, the Order of the Sacred Treasure in 1983, and theInternational Council on Combustion Engines (CIMAC) Gold Medal in 1985. Dr. Okamura died onJanuary 15, 1989.

Mitsuyasu DEGUCHI

Researcher, Japan Agency for Marine-Earth Science and TechnologyMarine Engineering Science Group, Engineering Department

Dr. Mitsuyasu Deguchi conducts research into channel (spatio-temporal)
equalization methods in the time domain to solve issues speciﬁc tounderwater acoustic communications such as using a multi-channel Decision
Feedback Equalizer (DFE) and time-reversal DFE.
A core member among R&D groups in this ﬁeld, he has devised and tested
diﬀerent ways to improve the DFE method. From this he has developed theAdaptive Digital Down-Conversion (ADDC) DFE and a Digital Phase Lock
Loop (DPLL). Simulations and real data have been used to analyze theireﬀectiveness compared to conventional DFE and an improved demodulation
performance has been demonstrated.
Through his wide knowledge and deep understanding of both sound wave
propagation phenomena and digital signal processing, Dr. Deguchi has
devised original and practical methods which can be implemented to solve
the unique obstacles of underwater acoustic communication.
The Techno-Ocean Network wishes to recognize the remarkable researchachieved already by Dr. Deguchi and has every expectation that he willcontinue to achieve such dramatic results in the future. As such, the TON
presents him with the Kenji Okamura Memorial Award for Pioneering theOcean Frontier , an award reserved for outstanding young researchers
driving the future of this ﬁeld.
