.... Depth-averaged simulations consider larger zones of the ice cover to examine a range of conditions that were observed during the past operation of the Kulluk in the Beaufort Sea. The simulations evaluate the effects of managed ice cover characteristics such as floe sizes and confinement. Predicted...

... ridges and multi-year floes) is also discussed. In addition, a method for deriving floe size distributions from analytical ice management predictions is briefly described. Finally recommendations for of future work in terms of increasing the reliability and accuracy of icebreaker performance and ice...

... of variables that can be altered by IM operations such as floe size, ice confinement and ice pressure. The results provide means for quantifying the benefits from icebreaking operations, which is a needed input for the design and optimization of IM systems. Ongoing work employs related techniques to determine...

... model tests result from flexural breaking of the floes. The flexural failure load is determined analytically using a beam on an elastic foundation modified for the effects of a finite beam length corresponding to the floe size. This is compared to other limit states of floe rotation and ridge-building...
