Mar 3, 2003 · Ice floe refers to the basic element of drift ice, characterized by granular ice floes that move on the sea surface as a two-dimensional system. AI generated definition based on: Encyclopedia of Ocean Sciences (Second Edition), 2009

Oct 15, 2023 · When the ice floe is tilted with a pitch angle, it could have emerged into the water and overwash could be more likely to happen. The comparison of overwash in a local view for the three ice floe models, Model 1, Model 2 and Model 3 in the given waves with λ/D = 1.5 and λ/D = 3.5 are presented in Fig. 14, respectively.

Mar 1, 2015 · The ice floe shape and size distribution are important ice parameters in ice-structure analyses. Before performing an analysis at full scale, the dynamic positioning (DP) experiments in model ice at the Hamburg Ship Model Basin (HSVA) allow for the testing of relevant image processing algorithms.

Sep 1, 2021 · Ice-floe resistance for varying ice thickness, obtained when Fr = 0.15; results of 1:52.667 KCS hull model. Download: Download high-res image (229KB) Download: Download full-size image; Fig. 12. Ice-floe resistance as a function of floe size, obtained when Fr = 0.15 and h = 0.02 m; results of 1:52.667

Nov 1, 2020 · The movement of an ice floe can be considered as the combination of translation and rotation, which was solved with the rigid-body motion equations in the body-fixed system based on the mass centre of the floe G−x'y’z’: (7) F = m d V G → d t (8) T = [J] · d ω G → d t + ω G → × ([J] · ω G →) where F and T are the total force ...

Dec 1, 2014 · The kinematics of a small sea-ice floe, which is relatively flat and thin in comparison to glacial icebergs, was given specific treatment by McGovern and Bai (2014) in a series of laboratory tests. These consisted of model tests in a range of wave conditions and floe variables with a view to determine the dependent variables of floe kinematics ...

Sep 1, 2016 · The possible wind effect is considered as follows. Initially, we start with one large ice floe (> a few km) which is formed by the aggregation of a number of relatively small ice floes (<1 km) with various thickness and/or sizes. When a strong wind blows over this region associated with the passage of a cyclonic system, breakup may occur ...

Jan 1, 2017 · The velocity of ice floe is an important parameter when calculating ice impact force on structures by using the Morison equation (Wong and Sego, 1989). In the numerical simulation, the velocity of floating body can be exported directly, while in the physical experiment the velocity can be calculated from the time series of body displacement.

Sep 15, 1999 · 3D processes like floe rafting and overturning, however, will affect the out-of-plane thickening, which is the critical factor for deciding the horizontal strength of ice jam and ice floe field (Hopkins and Tuhkuri, 1999; McKenna et al., 1997). 3D DEM was also adopted in simulations of ship interacting with ice floes (Lau et al., 2011; Vroegrijk, 2012; Ji et al., 2013).

Jul 1, 2014 · Pack ice is often found close to and in contact with arctic shipping and offshore drilling structures due to the melting process, wave action, and ice management operations. In low concentrations a single isolated ice floe may be a common occurrence in summer months and warmer climates (Timco, 2011). Such a floe, if small enough with respect to ...
