Abstract: Northern Sea Route (NSR) has attracted much attention from the academia. However, the relevant issues, namely, the seasonal variation of sea ice coverage, the possibility and delay of ice besetting events (IBEs), formulation of ice-breaker escort fee and rescue fee, and the internalization of environmental costs, are considered in past models, but not in a systematic manner. To break through the limitations of previous studies, this paper investigates the economic and environmental feasibility of the NSR for container service, and clarifies the said issues using the latest survey data on a business case. Specifically, a novel evaluation model was developed to estimate the required freight rate (RFR) comprehensively, from the perspective of economic and environmental costs. Based on the modeling results, the optimal scheme was designed for all-season commercial liner transportation via the NSR. Besides, the RFR-based logit competitiveness model was adopted to evaluate how the NSR as an alternative to the Suez Canal Route (SCR) is affected by multiple factors: the delay induced by the IBEs, carbon tax rate, loading factor of eastbound containerships, and fuel price. The research results provide reference for decision-makers to formulate operations plans for ice class, navigation speed, and ship type.
