HOUSTON — Harish Krishnamoorthy, assistant professor of electrical and computer engineering at the University of Houston (UH), has been selected by the Gulf Research Program (GRP) of the National Academies of Sciences, Engineering and Medicine as an early-career research fellow in the Offshore Energy Safety track.
He and four other fellows will “contribute to the understanding, management and reduction of systemic risk in offshore energy activities.” Krishnamoorthy is the first UH professor to win this GRP early-career research fellowship.
With expertise in power electronics, power converters and offshore technologies, Krishnamoorthy was recognized as an OTC Emerging Leader at the 2022 Offshore Technology Conference for “contributions to promoting workforce development in offshore with a strong focus on enhancing the safety and reliability of the electrical power systems and equipment as well as reducing the carbon emissions.”
His research interests include high-density power conversion for grid interface of energy systems, machine learning-based methods for improvement in quality and reliability of power electronics, advanced electronics and control for mission-critical applications.
Krishnamoorthy, who is also associate director of the Power Electronics, Microgrids and Subsea Electric Systems Center (PEMSEC) at UH, believes the Gulf of Mexico (GoM) offers various challenges and opportunities.
He estimates there are about 1,500 oil and gas rigs located offshore across the globe, with the largest share in the North Sea and the GoM. The current electric distribution system of oil and gas platforms is characterized as a weak electric grid in need of much improvement, according to the UH news release.
Offshore safety challenges
In addition, even though there are no large-scale offshore wind farms installed in the GoM, the recent initiatives by the federal government have raised interest in the idea. Several oil and gas companies, such as Shell, Chevron and Exxon, see this as an opportunity to cut their carbon emissions and are actively looking to contribute to the integration of offshore wind energy systems with subsea energy production activities. Moreover, the potential development of hydrogen as an “energy carrier” of the future has added a new dimension to offshore energy production and transportation activities.
All of these future possibilities come with increased safety challenges.
“When there are so many electronics involved, safety and reliability are going to be very critical,” Krishnamoorthy said. “I have been looking at safety aspects a lot in my research as well as how to connect subsea oil and gas systems with offshore renewable systems.”
The early-career award is not attached to a specific project, which UH says allows fellows to take on bold research they might not otherwise be able to pursue. Each of them will receive a $76,000 award, mentoring support and a built-in network of current and past cohorts. Krishnamoorthy said he is looking forward to using the funds to further his research work; work with mentor Ramanan Krishnamoorti, professor of petroleum engineering and vice president of energy and innovation at UH; and connect with a community of like-minded fellows.
The National Academies’ GRP is an independent, science-based program founded in 2013 as part of legal settlements with the companies involved in the 2010 Deepwater Horizon disaster. Its goal is to enhance offshore energy system safety and protect human health and the environment by catalyzing advances in science, practice and capacity, generating long-term benefits for the GoM region and the US.
“These exceptional individuals are working hard to pursue new research, technical capabilities, and approaches that address some of the greatest challenges facing the Gulf and Alaska regions today,” said Karena Mary Mothershed, senior program manager for the GRP’s board on Gulf Education and Engagement.
