Just in Time Port Call Optimisation: Preliminary Regulatory Compliance Evaluation and Environmental Performance Assessment

Abstract

Abstract Just in Time (JIT) arrival, as an operational measure towards shipping decarbonisation, promises increased energy savings and reduced emissions. Integrated digital systems targeting the optimisation of the port call process allow vessels to adapt their speed to avoid the “hurry-up-and-wait” syndrome, and thus, reduce their fuel consumption at a certain extend. However, there are a lot of concerns and challenges ahead for a wide adoption of such a solution, that are either related to the regulatory and standardisation frameworks, or to the realisation of the actual benefits of a JIT optimisation system. Thus, this paper attempts to shed light on some of these challenges, by focusing on the maritime regulatory framework around JIT operations and on emission reduction potential from speed adaptation. Results provide a baseline for regulatory compliance evaluation for such a system, and a preliminary environmental performance assessment from JIT arrival applied on an actual ship case. These insights and early results will be further explored within the EU-funded MISSION project towards a full appreciation of the JIT concept benefits and regulatory compliance, which will lead to its wide implementation.
