Abstract Offshore shuttle tankers play an important role in the oil transportation system for deep-sea and offshore marginal fields. The route scheduling of shuttle tankers determines the efficiency of the oil transportation system. Marine crude oil transportation mode accounts for 80% of the entire crude oil transportation volume. In order to improve the market competitiveness of crude oil companies and reduce their marine operation costs, the rational design of shuttle tanker fleet and the optimization of route scheduling are crucial. In recent years, scholars have focused more on researching the establishment of a green logistics system that is symbiotic with the environment and promotes the healthy development of the economy and consumer life. Based on this, this paper proposes a green scheduling optimization model for shuttle tanker paths based on continuous time expressions. The model aims to minimize the total cost of shipping for shuttle tankers, where the total cost of shipping consists of both traditional fixed transportation costs and variable costs related to carbon emissions. The model correlates carbon emissions with the speed of the shuttle tanker, i.e., the green scheduling optimization of the shuttle tanker route is achieved by optimizing the decision on the speed of the shuttle tanker. The model proposed in this paper simultaneously optimizes shuttle tanker fleet design, navigation route scheduling and speed selection. Through the case study and cost comparison of the cases, the important role of speed selection on the shipping cost of shuttle tankers is verified, which provides a new idea to reduce the cost of crude oil outbound from deep-sea and offshore marginal oil fields.
