摘要

Recently, shipping lines have focused on efficient ship operation, which relates to energy efficiency issues in shipping and, particularly, to operational issues such that the minimisation of fuel consumption and resulting greenhouse gas emissions. Efficient ship operation in container lines is closely related to the ship's time at sea and ship's time in port. Reduction in port time, thanks to high-quality port operations, allows improvement in the operational efficiency of a liner service by reducing the fuel consumption of a ship at sea and its resulting CO_2 emissions. The main goal of this article is to investigate how time in port affects efficient ship operation in terms of operating costs, CO_2 emissions and externalities. For this, as a methodology, a simulation based upon system dynamics is introduced. Major finding is that less time in port resulting from the improvement of port operations contributes to efficient ship operation in terms of operating costs, amount of CO_2 emissions and external effects in the liner shipping industry. In particular, a sensitivity analysis on efficient ship operation vis-a-vis the quality of port operation shows that bigger ships need to select highly productive calling ports that provide less time in port.
