Associate Professor Ng Szu Hui, Head of the Department of Industrial Systems Engineering and Management at the National University of Singapore (NUS) and Research Track Leader at the Centre for Maritime Studies (CMS), delivered an insightful presentation titled “Charting a Course Through the Uncertainties of Maritime Energy Transition” at the Singapore Maritime Research Conference (SMRC) 2025, organised by the Singapore Maritime Institute (SMI).

The session spotlighted the mounting pressures and complexities that shipowners, operators, and policymakers face as they work toward decarbonising the global maritime sector.

Embracing Complexity in Decarbonisation

Associate Professor Ng highlighted that while interim efficiency measures can yield short-term benefits, the long-term success of decarbonisation efforts hinges on the adoption of low-carbon alternative fuels. However, the path forward is fraught with uncertainties, including fluctuating green fuel costs, supply chain limitations, and the readiness of supporting infrastructure.

The Imperative for Robust, Adaptive Strategies

Drawing from her extensive research, Associate Professor Ng advocated for robust and adaptive fleet renewal strategies that can withstand the dynamic nature of the maritime energy landscape. Such strategies should account for various scenarios, enabling stakeholders to make informed decisions that balance environmental goals with economic viability.

Her work aligns with Singapore's broader initiatives to support maritime decarbonisation. For instance, the Maritime and Port Authority of Singapore (MPA) has been actively developing regulatory frameworks and standards for alternative fuels like methanol and ammonia, aiming to ensure safe and efficient adoption at a commercial scale.

Recognising Excellence in Maritime Research

In recognition of her significant contributions to maritime research, Associate Professor Ng was honoured with the inaugural SMI Fellows Award in 2023. This accolade acknowledges her leadership in projects focusing on shipping emissions, decarbonisation, and shipping network design. Her expertise has also been instrumental in international efforts, serving as an expert reviewer for the Fourth IMO GHG Study and comprehensive impact assessments of short-and mid-term measures.

Advancing Maritime Sustainability

Associate Professor Ng's presentation serves as a clarion call for the maritime industry to embrace uncertainty with strategic foresight. By developing flexible and resilient approaches to fleet planning and fuel adoption, the industry can better navigate the complexities of the energy transition, ensuring a sustainable future for global shipping.
