Hans Jürgen Krock, Ph.D., P.E.
President
OCEES International, Inc.

     His diverse experience in industry, government, and academia has provided Dr. Krock the solid background required to make OCEES International, Inc. a successful enterprise. His experience encompasses a wide range of activities including practical engineering, innovative research, graduate instruction, environmental regulation, business development, and administration.

     Dr. Krock’s educational background includes:

    • Bachelor of Science in Civil Engineering – Arizona State University – 1965 Magna Cum Laude
    • Master of Science in Sanitary Engineering – University of California, Berkeley – 1967
    • Doctor of Philosophy – Environmental Engineering – University of California, Berkeley – 1972
    • Minor subjects covered in his Ph.D. studies were Chemistry and Chemical Engineering.

     Dr. Krock has conducted engineering and research projects in Arizona, California, Hawaii, American Samoa, Saipan, Guam, Majuro, Kwajalein, Palau, Ponepe, Puerto Rico, The Bahamas, South Korea, Roi-Namur and Germany. For the past twenty two (22) years, Dr. Krock has devoted a majority of his research and professional efforts towards the optimization and development of OTEC related technologies. Among his research and professional accomplishments pertaining to OTEC Systems applications include, but are not limited to:

    • Establishment of water quality standards for the state of Hawaii and for American Samoa (1979)
    • Determination of gas exchange rates in seawater (1981-1993). This work has resulted in one patent and one patent pending. This invention increases the efficiency and lowers costs in OTEC plants.
    • Optimization of the design of OTEC Systems (1980-Present)

     During his career, Dr. Krock has had positions in industry (Bagdad Copper Corporation), with governmental agencies (Arizona State Department of Health, Los Angeles County Sanitation Districts, Alameda County Flood Control Districts), with an electric and water utility (Salt River Project), with an engineering firm (Sunn, Low, Tom and Hara, Inc.) and with academia (University of California at Berkeley, University of Hawaii at Manoa). In addition, Dr. Krock has established International Hydrogen Systems, Inc. and OCEES International, Inc.

    Dr. Krock is a registered Professional Engineer in the State of Hawaii (Civil Branch) and a tenured full Professor in the Department of Ocean Engineering of the University of Hawaii. He has served as chairman of the Department of Ocean Engineering and as Director of the J.K.K. Look Laboratory of Oceanographic Engineering. He is a member of a dozen professional and scientific associations and is a registered Scientific Diver. 

     Among his research and professional accomplishments, Dr. Krock lists the following:

    • Optimization of the design of OTEC systems (1980 to present).
    • Determination of the differences between the beach processes on tropical islands and those on continental coasts as based on the engineering characteristics of coral sand (1984 to present).
    • Determination of the relationship between nutrient concentrations (either total nitrogen or total phosphorus) and net phytoplankton growth rates in real world tropical estuaries, embayments and open coastal waters (1973-1997).
    • Determination of gas exchange rates in seawater (1981-1993). This work resulted in one patent and one patent pending. This invention increases the efficiency and lowers costs in OTEC plants.
    • Establishment of water quality standards for the State of Hawaii and for American Samoa (1979).
    • Determination of the response of tropical benthic communities (primarily coral based) to the discharge of domestic wastewater receiving a range of treatment (1976).
    • Development of a sensitive and rapid bioassay procedure which uses the metabolic response of native microbiological communities to measure both toxic and stimulatory responses (1971).
    • Optimization of the demineralization of brackish water using ion exchange (1968).
    • Development of a method to use epoxy to repair extensive cracking of a high arch concrete dam (Stewart Mountain Dam, 1963).
