Abstract: A large number of mitigation strategies including both technical and operational measures have been proposed to reduce ship energy consumption and hence carbon emissions. Under cost and other practical constraints, when prioritizing among mitigation measures, different data sources such as observed data from physical systems and simulated data from simulation models may be used. Data obtained from different sources have different characteristics in terms of accuracy and data volume. Therefore, it is important to integrate different data sources when evaluating alternative mitigation measures in a systematic and systemic manner. In response, a Gaussian process metamodel based method is proposed to evaluate energy saving measures when different data sources are combined synergistically. In addition, a cost-effectiveness analysis is used to prioritize the mitigation strategies based on cost considerations. A case study is developed to demonstrate the advantages of the proposed method in terms of accuracy and efficiency. All mitigation measures selected in the case study are found to have a negative cost which can translate to both energy and cost savings. Among the evaluated measures, speed reduction has shown to be the most plausible measure in terms of energy savings and marginal cost-effectiveness.
