Melting Arctic waters have brought about global opportunities and challenges. One distinctive opportunity presented by the increasingly ice-free Arctic Ocean is its availability for shipping cargos between Europe and Asia. In adopting highly simplified assumptions of the Northern Sea Route (NSR) being navigable and economical enough for shipping and NSR completely substituting for the incumbent Suez Canal route, this paper analyzes the maximum number of voyages possible for the transshipment of container cargo throughput for Korea's trade with Europe, particularly with Europe-17 and Europe-7. Our analysis shows the number of voyages range from over 2,900 to as little as 237 for Europe-17, depending on vessel sizes, when NSR is available for the whole year. With NSR opening for three months, the corresponding figures vary between 727 and 60 for Europe-17, and the figures for Europe-7 are between 2,725 and 222 and 682 and 56 voyages, respectively.

While IMO's e-Navigation project's scope is to enhance safety of navigation by improved ship-to-shore-cooperation, the EU's FP7 project MUNIN's aim is to develop a concept for an autonomous dry bulk carrier, that is at least as safe as a manned vessel. As e-Navigation has a strong focus on improving the human element in shipping and MUNIN tends towards an unmanned bridge, a common baseline might look quite contradictory at first, but they share the need to ensure and enhance the safety of navigation. After an introduction into e-Navigation and the MUNIN project, this paper will demonstrate with two examples, how MUNIN's results address identified e-Navigation's gaps and addresses e-Navigation's user needs. Thus, MUNIN contributes to the development and implementation of the prioritized e-Navigation solutions.

Over the last 30 years the extent of sea-ice covering the North Pole has declined about 15∼20% on average, and it is expected that by the end of the 21st century, vast areas of the Arctic Ocean will be ice-free during the summer season, thus, increasing the possibility of ship navigation across the Arctic Ocean.

In this paper, we have developed a model of shipping for the Northwest Passage (hereinafter NWP) in northern Canada to determine whether ice thinning will make this route more economically viable when compared with the Panama Canal. Among the 7 routes of the NWP, Route 2 and Route 3 offer better navigational conditions than the others. However, Route 3 has a depth limit of only 10m, so here we use Route 2 which is suitable for deep draft navigation to carry on our analysis. Container ships of 4,500∼15,000 TEU under Hub and spoke mode, container shipping between Busan port and New York port is simulated for the Panama Canal and the NWP.

This paper considers Canada's sovereignty in matters of navigation over the waters at the Arctic Archipelago, in the form of a toll fee for passage usage. We concluded that the NWP has an advantage over the Panama Canal if it is open for free international passage, regardless of ship size. However, if it is not free, its advantages depend on its toll fee. The lower the toll fee is, the more advantages the NWP will boast.

New e-navigation strains require new technologies, new infrastructures and new organizational structures on bridge, on shore as well as in the cloud. Suitable engineering and safety/risk assessment methods facilitate these efforts. Understanding maritime transportation as a sociotechnical system allows the application of system-engineering methods. Formal, simulation based and in situ verification and validation of e-navigation technologies are important methods to obtain system safety and reliability. The modelling and simulation toolset HAGGIS provides methods for system specification and formal risk analysis. It provides a modelling framework for processes, fault trees and generic hazard specification and a physical world and maritime traffic simulation system. HAGGIS is accompanied by the physical test bed LABSKAUS which implements a physical test bed. The test bed provides reference ports and waterways in combination with an experimental Vessel Traffic Services (VTS) system and a mobile integrated bridge: This enables in situ experiments for technological evaluation, testing, ground research and demonstration. This paper describes an integrated seamless approach for developing new e-navigation technologies starting with simulation based assessment and ending in physical real world demonstrations
