... ABSTRACT This paper gives numerical assessment results for the change of ship propulsion performance in old ice channel clogged with brash ice as compared with open-water conditions taking ice-going ship Yury Topchev as a case study. The authors have shown that two factors must be taken...

... ABSTRACT In this paper, the computation of wave loads on a ship in an ice channel is carried out through a boundary integral equation method. The ice channel is confined between two semi-infinite ice sheets. The linearized velocity potential theory is used for the fluid flow and the thin...

... ABSTRACT The shoulder becomes the main ice breaking area when the carrier is sailing in the narrow ice channel of the Arctic. Therefore, it is significant to study and evaluate the structural response of shoulder. In this paper, an ice-water-ship coupling numerical simulation model, which...

... ABSTRACT This paper introduces a calculation model for evolution of navigation channel cross-section with allowance for processes of thermal exchange at air-ice and ice-water interfaces, brash ice accumulation in ice channel after each run of vessel, brash ice consolidated layer formation...

... management requires a sufficiently large channel width and small floe size in drifting sea ice. Efficient ice management has to estimate the ice channel managed by the icebreaker, and support proper planning of vessel operations and deployed configuration. Moran et al. (2006) reported ice management...

... size ahead of a stationary drilling vessel will be a key component of offshore Arctic exploration and development drilling. Selection of the management vessels and fleet deployment configuration is critical to insure the ability to (1) maintain the drilling vessel within the managed ice channel as ice...
