Safe navigation of cruise ships in greenlandic waters - legal frame and practical challenges

Rasmussen H. B., Feldtmann B.

TransNav : International Journal on Marine Navigation and Safety of Sea Transportation

2020

Vol. 14, no. 1

207--212

Climate change provides for improved conditions for maritime navigation and results in increased activity in the Arctic. Those increased activities influence the safety at sea and risk of accidents. A disaster as the Costa Concordia incident would have far more serious consequences in Greenlandic waters than it had in Italy, therefore the question of prevention and disaster-preparedness is crucial. One approach to avoid risks is to create specific legislation. The legal system guiding safe navigation of cruise ships in/around Greenlandic waters is complex: the legal regime for navigation is set in different general and specific international, regional and national legal acts, partly non-binding, therefore issues of effectiveness arise. Safety is also influenced by practical issues, e.g. the lack of sufficient nautical charts for Greenlandic waters and “preparedness” at land to handle potential disasters, such as the SAR-system and preparedness of different actors, for example hospitals.

Principles of vessel route planning in Ice on the Northern Sea Route

Vol. 10, no. 4

587--592

A complex of ice cover characteristics and the season of the year were considered in relation to vessel route planning in ice-covered areas on the NSR. The criteria for navigation in ice - both year-round and seasonal were analyzed. The analysis of the experts knowledge, dissipated in the literature, allowed to identify some rules of route planning in ice-covered areas. The most important processes from the navigation point of view are the development and disintegration of ice, the formation and disintegration of fast ice and behavior of the ice massifs and polynyas. The optimal route is selected on basis of available analysis and forecast maps of ice conditions and ice class, draught and seaworthiness of the vessel. The boundary of the ice indicates areas accessible to vessels without ice class. Areas with a concentration of ice from 0 to 6/10 are used for navigation of vessels of different ice classes. Areas of concentration of ice from 7/10 up are eligible for navigation for icebreakers and vessels with a high ice class with the assistance of icebreakers. These rules were collected in the decision tree. Following such developed decision-making model the master of the vessel may take decision independently by accepting grading criteria of priorities resulting from his knowledge, experience and the circumstances of navigation. Formalized form of decision making model reduces risk of the "human factor" in the decision and thereby help improve the safety of maritime transport.

Functionality of Sea Ice Data Sources on the NSR

Vol. 10, no. 3

441--450

The functionality of available official sources of sea ice data for the Northern Sea Route to date is low. In recent years a large number of new publicly available sources have appeared. Their functionality for purposes of route planning has yet to be evaluated. This study presents results of qualitative and expert analyses of various sources. It is proposed to use new indicators to enable comparison of functionality of data sources. New sources provide the technical progress that is instrumental in reducing the amount of effort and influence of the human factor in the decision-making system. The study also presents solutions to the problem of limited bandwidth available at high latitudes with Iridium satellite system. Presented solutions can be used on any vessel by any company or navigator to implement or design the decision support system related to route planning in ice in accordance with the requirements of the ISM Code and concept of e-Navigation.
