Abstract
This paper applies a Multi-Objective Robust Decision-Making framework, combined with an Epoch-Era Analysis, to evaluate decarbonisation strategies for ocean- and global-class research vessels. The method incorporates deep uncertainties across technological, operational, regulatory, and economic aspects and compares configurations based on technical feasibility, greenhouse gas emissions, and lifecycle costs. The analysis covers conventional and alternative fuels, energy converters, and energy-reduction technologies. Methanol-based concepts emerge as robust low-carbon options across all operational profiles, while ammonia shows additional potential for lower-demand vessels. Iterative analyses of blended fuels and hull-form variations further demonstrate the approach's flexibility for exploring adaptive design strategies and highlight the potential of transitional fuels.
