| In the face of severe environmental situation,the International Maritime Organization(IMO)decided to impose sulfur restriction in the global waters in January 1,2020.However,due to the impact of COVID-19,many countries slowed down or even suspended the implementation of the sulfur limit.Many ports in foreign countries reduced the detection of fuel for port ships.With the relief of the epidemic,the impact of sulfur restriction will come.Among them,the rising price of low sulfur fuel will increase the cost of container shipping in Asia and Europe.Therefore,it is urgent to optimize the operation plan of containers in Asia and Europe to control the cost after the implementation of the sulfur limit order.As for the Asia Europe route,the Mediterranean route through the Suez Canal is the main route at present.However,due to the risk of congestion in the narrow Suez Canal,the Arctic route can be opened into people’s view due to climate warming.Compared with the traditional Mediterranean route,the Arctic route has a great distance advantage.However,due to the Arctic ice situation and other factors,many shipping enterprises give up the Arctic route.However,after the sulfur limit order,the distance advantage of the Arctic route will be more obvious.Therefore,this paper establishes the route competitiveness model and analyzes the feasibility of the Arctic route after the sulfur limit order,At the optimal speed,the probability of choosing the Arctic route for different container ships meeting the Arctic route limit increases to about50%,and the pollution problem of the Arctic route has been significantly alleviated,which indicates that the Arctic route is feasible to replace the traditional Mediterranean route after the sulfur limit,The replacement of the Arctic route will also be included in the New Asia Europe shipping as a strategic plan for operation optimization,which will enable shipping companies to have more choices in the face of the impact of the sulfur limit order.Finally,a trans Arctic Eurasian operation optimization model is established and solved by CPLEX.The following conclusions are drawn through the analysis of an example.(1)The shipping companies that choose the Mediterranean route can control the cost by reducing the speed outside the emission control area and increasing the speed inside the emission control area,but the speed inside the emission control area still needs to be lower than that outside the emission control area.(2)Changing the Arctic route to replace the traditional Mediterranean route can save costs,but it needs additional investment in the operating costs of Arctic ships,and it also needs to change the order of the original port of call.When the shipping company’s capacity is insufficient,changing the Arctic route will become the preferred way.(3)For the Arctic route,the cost of ice breaking has become the key to hinder the further improvement of the economic benefits of the Arctic route.When the cost of ice breaking of the Arctic route is reduced in the future,choosing the Arctic route for Asia Europe Container Transportation will have greater benefits.(4)Mediterranean route is more sensitive to the price change of HFO fuel.When the price of HFO fuel continues to rise,shipping companies can choose to change the Arctic route,or levy fuel surcharge and slow down delay delivery to deal with it. |
