“…Also, the political situations of the costal countries are complex. Nevertheless, the situation of lacking of necessary navigation aid and navigation experience in the north-pole is still severe, which makes navigation in the Arctic Ocean even more dangerous [8]. This article analyses and evaluates the navigation environment of NSR which provides a scientific reference for the coming safe NSR navigation and its effective development.…”

With the global warming in recent years, the ice on the Arctic channel has gradually melted, and the Arctic channel has become the focus of attention in the maritime sector. In order to study the navigation of the Arctic route, this paper builds a model for the navigation environment of the Arctic route, selects the meteorological factors, hydrological factors, geographical factors and transportation factors as the first-class indexes of navigation environment. The weights of the indexes are given by analytic hierarchy process. On the basis of this, the Arctic is unsafe and navigable which could be obtained to provide some references for the relative researchers.

“…It remains unclear whether the navigational risk of the NWP has been significantly reduced, where the highest risks of the NWP are, and how the navigation risk of the NWP will change in the future, particularly for ships with different ice-breaking capabilities. Sea ice and other meteorological and hydrological risks such as strong wind, low visibility, low temperature, and shallow water segments serve as major impediments to ship navigation [28][29][30][31][32][33] and present some additional risk-influencing factors of the natural environment: heavy waves mixed with drifting ice, icing of the ship, and prolonged periods of darkness. These factors may have an increasing effect on the number of accidents such as collisions, groundings, and instrument failures, raising worries about transport in the NWP.…”

Risk Assessment of Ship Navigation in the Northwest Passage: Historical and Projection

et al. 2022

Shipping volumes in the Northwest Passage are likely to increase under climate change due to the distance advantage over traditional routes and the special strategic location of the Arctic. However, the harsh environment and poor channel conditions may pose a considerable risk to ship navigation. To ensure the safety of ships, understand the navigability of the route, and plan the sustainable use of the Northwest Passage, it is crucial to provide a quantitative risk assessment. Here, we present an analysis of several natural risks faced by ships in the Northwest Passage based on available datasets and use climate model simulations to project the navigability changes. The results showed that: (1) The sea-ice risk to ships in the Northwest Passage has been significantly reduced over the period 1979–2019, and the risk for Polar Class 6 (PC6) ships has decreased more rapidly than for general open-water (OW) ships. The difference in ice-breaking capacity further affects the seaworthy season, with the second seaworthy month being August for OW ships and October for PC6 ships, in addition to the commonly best September. (2) Low visibility is a more common form of adverse weather than strong wind for navigation in the Northwest Passage, mainly on the northern route, although pilotage conditions appear to be improving in September. (3) According to the comprehensive risk map, the distribution of risk is dominated by sea ice. The southern route of the Northwest Passage is superior to the northern route in terms of both sea ice and weather conditions, but there is a risk of shallow water. (4) For the northern route, which has greater transport potential, projections suggest that the sea-ice risk will be steadily lower than any extreme light ice year observed historically whether for the ship class OW or PC6 by 2050, with an increase of 50–80 navigable days, and the navigable period could be from June to January of the following year for PC6 ships by 2100. Our results provide valuable information for ships planning to pass through the Northwest Passage.
