... characteristics (floe size, floe thickness, inclusion of brash ice and small ice pieces, ice drift speed and direction) and DP system (gain set-ups). Over the years, many engineers have been using numerical and experimental tools to assess the effect of these parameters. More recently, a comprehensive series...

... Abstract With a series of physical model tests performed during February to August 2016, Arctic towing operation was investigated while towing a Gravity Base Structure (GBS) in managed sea ice with varying parameters: ice concentration, floe size, towing speed and towing configuration...

... Abstract During ice management operations, creating narrow parallel channels with icebreakers can effectively reduce ice floe sizes for the protected vessel/structure. Yet too narrow channel spacing requirement shall lead to excessive or even unpractical ice management operations. Empirical...

... and the interaction process with the ice sheet was monitored and documented. Relevant parameters like the crack length and orientation and resulting floes size distribution after different runs of wave application were measured and analysed by image processing. The relation between controlled wave parameters and ice...

... Abstract The present paper describes a simulation tool for physical ice management operations. Resistance in level ice or in floes and manoeuvrability in ice are estimated thanks to semi-empirical methods and validated through comparison with model test data. From a target floe size, trajectory...

We use a truncated power law for the floe size distribution, following the observations of Toyota et al. (2011). The maximum floe size isdetermined by the dominant wavelength in the ice...

... into sufficiently small floe sizes. Additionally, the ice drift heading varies constantly, with frequent changes of 180 degrees or more in a few hours, which challenges the fleet's ability to maintain the protected vessel within the managed ice channel created by icebreakers working updrift in the moving ice...
