Abstract
Sang-Su Lee’s indexed research reflects an engineering focus on maritime propulsion, ship energy efficiency, and the safety implications of technical modifications introduced to meet contemporary environmental-performance requirements. A notable 2024 article in Results in Engineering evaluates a redesigned shafting system following a propeller redesign intended to improve CII and EEXI performance. The study considers a 6500 TEU container ship and examines engine power limitations, torsional vibration, and shaft alignment to assess the safety of the modified propulsion arrangement. [1]

Introduction
Maritime transportation is undergoing significant technical and regulatory changes aimed at improving energy efficiency and reducing greenhouse-gas emissions. International maritime regulations have introduced performance indicators including the Energy Efficiency Existing Ship Index (EEXI) and Carbon Intensity Indicator (CII), creating engineering requirements that affect propulsion-system design and vessel operation. Lee’s research addresses this intersection between regulatory performance and mechanical engineering by examining how modifications intended to improve vessel efficiency influence shafting-system safety. [1]
Research Profile
Lee’s documented research profile is situated within engineering applications related to maritime systems. His published work connects ship energy-efficiency requirements with propulsion-system analysis, particularly where changes to propeller or engine configurations can influence mechanical loads and shafting performance. The research therefore occupies an interdisciplinary position between marine engineering, mechanical-system safety, and environmental performance.
Research Contributions
The principal documented contribution concerns the engineering assessment of a redesigned shafting system implemented following propeller redesign intended to improve CII and EEXI performance. The study examined a 6500 TEU container ship and determined engine power limitations under EEXI-related requirements before assessing the resulting implications for CII. The redesigned shafting system was subsequently evaluated through torsional-vibration calculations and shaft-alignment analyses. [1]
Publications
The supplied Scopus record identifies two indexed documents for Sang-Su Lee. One documented publication is the 2024 open-access article listed below.

Research Impact
According to the supplied researcher profile, Lee’s work has accumulated 60 citations across two indexed documents, with an h-index of 2. Bibliometric indicators can provide a quantitative indication of scholarly visibility, although they do not by themselves establish research quality or significance. In this context, the documented publication addresses a practical engineering problem relevant to ship operators, propulsion-system designers, classification and technical organizations, and researchers studying maritime energy efficiency.
Award Suitability
Sang-Su Lee’s documented research profile provides a relevant basis for consideration for the Best Researcher Award under the International Popular Scientist Awards. The basis for consideration includes an identifiable engineering research record, indexed scholarly publications, citation activity, and research addressing contemporary challenges in maritime propulsion and energy efficiency. [1]
Conclusion
Sang-Su Lee is an engineering researcher affiliated with Korean Register whose documented scholarly work addresses marine propulsion, shafting-system safety, and vessel energy-efficiency requirements. His 2024 publication on redesigned shafting following propeller redesign provides a concrete example of research connecting CII and EEXI objectives with torsional-vibration and shaft-alignment analysis.
