Abstract

Maritime decarbonization in Indonesia requires a coordinated approach linking vessel operations and port electricity infrastructure. This paper examines the feasibility of Green Logistic Ships (GLS) combining energy-efficient propulsion, just-in-time (JIT) arrival, shore power (cold ironing), and emissions monitoring. The study uses a traceable document-based review of Statistics Indonesia (BPS) sea transport publications for 2021–2024, International Maritime Organization (IMO) instruments, a shore-connection technical standard, and peer-reviewed research. A four-layer integration framework is proposed, with a reproducible method for evaluating fuel use, transport work, port electricity demand, and grid-adjusted emissions. The review establishes the relevance of shore power and operational optimisation but does not treat unverified fleet-wide efficiency estimates, port power-capacity values, or financial payback figures from an earlier draft as observed results. The principal output is an evidence-based technical assessment framework and a list of vessel- and port-level data needed to quantify Indonesia-specific benefits.
