摘要

船舶传统上以重油(HFO)和船用柴油(MDO)等化石燃料为动力,排放的颗粒物、碳氢化合物(HC)、一氧化碳(CO)、氮氧化物(NOX)和二氧化碳(CO2)等会对环境和人类健康造成负面影响。国际海事组织(IMO)鼓励航运公司使用液化天然气(LNG)替代传统船用燃料,因为液化天然气是一种绿色燃料,可以为航运活动提供动力,而且易于储存。常见的液化天然气加注方法有三种:船到船、车到船和港到船。本研究的目的是利用整数线性规划(ILP)模型,考虑三种成本:固定成本、可变成本和额外成本,确定港口的最佳加气方法。为了找到最佳加油方法,将三种方法及其相关约束条件建模到 ILP 模型中。结果表明,在所考虑的港口情况下,船对船是液化天然气的最佳加气方式。我们还进行了数值实验,以验证模型的性能并提出管理见解。

LNG bunkering infrastructure planning at port

Ships are traditionally powered by fossil fuels such as heavy fuel oil (HFO) and marine diesel oil (MDO), where the emissions, such as particulates, hydrocarbons (HC), carbon monoxide (CO), nitrogen oxides (NOX) and carbon dioxide (CO2), negatively affect the environment and human health. The International Maritime Organization (IMO) encourages shipping companies to use liquefied natural gas (LNG), which is a green fuel source to power shipping activities and is easy to store, to replace traditional marine fuels. There are three common methods of LNG bunkering: ship-to-ship, truck-to-ship, and port-to-ship. The objective of this study is to determine the optimal bunkering method at a port using an integer linear programming (ILP) model considering three kinds of costs: fixed, variable, and extra. To find the optimal bunkering method, the three methods and their related constraints are modeled into the ILP model. The results indicate that ship-to-ship is the optimal bunkering method for LNG under the scenario of the port considered. Numerical experiments are conducted to validate model performance and generate managerial insights.
