Seaports face significant environmental challenges in their role as hubs for logistics activities, particularly since ships are significant contributors to energy consumption, global warming and air and marine pollution. The environmental pressures facing ports has led to the emergence of the green port concept. Port Klang is the largest port in Malaysia, characterised not only by significant container throughput, but also by significant congestion issues, emissions and pollution. These characteristics led to the selection of Port Klang, the nation's major seaport, as a case study for this analysis of the variables most relevant in the effective implementation of the green port concept and subsequent research into how this green seaport concept influences a seaport's future competitiveness. To achieve these aims, the Analytic Hierarchy Process (AHP) has been employed. The findings of the analysis suggest that environmental quality, the use of energy and resources, waste handling and habitat quality and greenery are the critical influential factors required for establishing green port hub status and that then port competitiveness is most significantly affected by green operations, sustainable equipment, resources management and cost efficiency at seaports.

The selection of steaming speed is one of the main strategic decisions for ship operators under highly uncertain conditions. Speed reductions are of great benefit to the economy and environment in shipping operations. Since the inappropriate choice of steaming speed levels brought about a substantial financial and environmental impact on organisations, it is crucial to make precise decisions in the implementation of different levels of steaming speed. However, given its significance, the right pace of steaming for ship tankers benefiting the economy and the environment is still under investigation. Therefore, this study is undertaken to determine the most suitable steaming speed for chemical tankers under unpredictable operating conditions. To address this issue, an evaluation model based on the Analytic Hierarchy Process (AHP) and the Technique for Order Performance by Similarity to Ideal Solution (TOPSIS) is developed. The result indicates that extra slow steaming is the most acceptable steaming speed employing an integrated approach. This study envisages that the steaming speed of a ship can be considered as one of the strategies for a shipping company to reap financial and environmental benefits. [ABSTRACT FROM AUTHOR]

Seaport inefficiencies have caused hindrances on the seaport operations especially on operational disruption which eventually contributes to high cost expenses, unnecessary waste and environmental pollution, and capital losses. As a result, the business and environmental sustainability cannot be attained and affecting the whole supply chain. Therefore, a Lean, Agile, Resilience and Green (LARG) performance model is proposed as a mechanism to curb these issues and improving the competitiveness of seaports. The compatible LARG criteria in seaport supply chain have been identified and analysed using an extensive literature and expert's reviews. In order to meet the aim of the paper, fifteen (15) experts from various maritime background (i.e. academic and industry experts) have been selected to give the relative important of each LARG paradigms by using an Analytical Hierarchy Process (AHP). The result shows that operational performance has the highest contribution to the seaport supply chain performance followed by economic performance and environmental performance. The outcome of this paper can be utilised as a guideline for seaport practitioners to develop a management tool to boost their performance from the LARG aspect. Furthermore, this LARG management tool can be applied globally as it can be adjusted and adaptable suited the seaport preferences. [ABSTRACT FROM AUTHOR]
