Despite shortening voyages between Asia and Europe by the Northern Sea Route (NSR) over the Suez Canal route (SCR), increased NSR’s traffic intensifies vessel-based emissions to the Arctic Sea. This study investigates NSR’s feasibility with a combination of operational and regulatory emissions control (EC) measures against the SCR and NSR’s status...

Spatial and temporal variations of shipping along Russia's Northern Sea Route (NSR) were investigated to better understand the possible drivers of traffic levels and future trends. Daily information for ships sailing along the NSR were collected, and voyage-based analyses were conducted for a period from March 2013 to December 2018. Annual total de...

Northern Sea Route (NSR) is focused on because it might bring a higher efficiency of logistics between Europe and Asia. However, until the route becomes a major transport route, there will be challenges. The purpose of this paper is to discuss both opportunities and challenges by focusing on different elements: technical feasibility, economic feasi...

This paper investigated characteristics of shipping activity along the Northern Sea Route between 2013 and 2017. Authors collected ship information including ship type, and position from Northern Sea Route Administration. Based on these ship information, characteristics of current shipping activity was investigated.

This paper examines statistical characteristics of sea ice concentration and thickness in the Arctic Ocean to evaluate navigability and its risk along the Northern Sea Route. Authors retrieved the sea ice concentration and thickness information from "TOPAZ4" data set, which is a data assimilation system of sea ice condition in the Arctic Ocean. Fro...

Although sea-ice in the Arctic Ocean is decreasing due to global warming, sea-ice still exists on the Northern Sea Route in the summer season. In order to evaluate reduction of the sailing speed by sea-ice, relationship between ship's navigation data derived from Automatic Identification System and ice condition data such as sea ice concentration a...

This Special session was conducted with the aim of introducing actual ocean development in the Arctic which has utilized the Northern Sea Route for logistics of construction, and discuss perspective of the Northern Sea Route. In the first half of the session, two speakers were invited to introduce LNG plant module shipment through the Northern Sea...

Ongoing sea ice retreat in the Arctic Ocean eases the navigability of the Northern Sea Route. However, it should be utilized under sustainable manner. This paper aims at over viewing recent research activities, which have been carried out under the national research project of GRENE and ArCS for the purpose of investigating issues on sustainable Ar...

Feasibility of the Northern Sea Route is examined by navigability of icy waters and sailing speed considering recent summer sea ice condition. And economic feasibility focusing on shipping cost is also examined by estimating dry bulk, liquid bulk, finished car, LNG and container.
