... capacity of the NSR; besides, new requirements for navigation support were developed. There emerged a necessity of specialized ice information on ice conditions directly along the ship routes. These tasks require study of ice cover as a navigational environment, as well as developing the algorithms...

... ABSTRACT The continuous melting of Arctic sea ice has attracted increasing interest in the potential of navigation in the Arctic route. Most existing studies use the sea ice concentration (SIC) to evaluate the sea ice condition along the route. Based on the historical sea ice data (including...

... that there are not enough Arctic icebreakers available while the number of merchant vessels that need assistance is growing. In this case icebreaker assistance is carried out under the most severe ice conditions of the route. The areas of light ice conditions are overcome by ice vessels independently. Taking the latter...

... conditions. Ice-going ships are a kind of merchant ships that do not need icebreaker escort and thus can proceed independently. Icebreakers are specialized ships that are intended to assist other ships in ice, which should be able to operate in the most severe ice conditions in the operational waters...

... structural design and most Arctic operation planning, ice load calculations are one of the key components. However, ice load calculation is complicated by various ice conditions and different ice failure modes. As Palmer et al. (1983) stated, ‘ it is no more likely that there should be a universal ice-force...

... and FPSO, the influence of sea ice on the mooring system is analyzed. Finally, taking a typical FPSO single point mooring system as an example, the safety of performance of an FPSO under extreme ice conditions is analyzed using ANSYS numerical simulation. INTRODUCTION During the development of marine...
