Pendulum transportation mode on the Northern Sea Route
According to the change law reflected in the Arctic shipping data,the characteristics of Arctic shipping were sys-tematically arranged as follows:the navigation period covered summer and autumn,the shipping volume was constrained by external conditions,the shipping structure was single and ex-ternal transportation was the mainstay.On this basis,a pen-dulum transportation mode that was more suitable for Arctic shipping in terms of transportation time,transportation com-plexity,and transportation range was proposed.The pendulum transportation mode of the Northern Sea Route was designed from three aspects:fulcrum port,ship type,and modular transportation,and the annual shipping revenue of the pendu-lum transportation mode was compared and analyzed with tra-ditional and mixed transportation modes.The results show that compared with the other two transportation modes,the pendu-lum transportation mode of the Northern Sea Route can com-plete one more voyage per year,and the annual shipping reve-nue increases by 9%and 11.3%,respectively.
