Ice Resistance Assessment for a Large Size Vessel Running in a Narrow Ice Channel Behind an Icebreaker

A Combined Experimental and Numerical Approach to Predict Ship Resistance and Power Demand in Broken Ice

“…A further formula to estimate R i was proposed by Sazonov and Dobrodeev (2021), which is based on an earlier semi-empirical method for the calculation of ice resistance in the newly created broken ice channel. In the derivation of their formulas, they mainly relied on their model test data (Dobrodeev, 2018).…”

“…In practice, unlike the brash ice channel or broken ice field, navigating in the newly created broken ice channel is becoming a common ice condition for ships following an icebreaker. A semi-empirical equation for estimating hull resistance in a broken ice channel was proposed (Sazonov and Dobrodeev, 2021). Their formula takes the effect of ice channel width into account, which is also an attempt to consider the factor of specialization.…”

“…The models can be categorized based on their scenario features into e.g. models on global ice loas in level ice (Tan et al, 2014;Xuan et al, 2021;Li et al, 2020;Li et al, 2020b;Ni et al, 2020) as well as escort in level ice (Liu and Ji, 2021), ice resistance in pack and thin ice (Zong and Zhou, 2019), ship resistance in open-water ice channel (Huang et al, 2021), narrow ice channel (Sazonov and Dobrodeev, 2021;Li et al, 2021) as well as in restricted brash ice channel (Zhang et al, 2022;Luo et al, 2020;Xie et al, 2022), ship resistance in unconsolidated ridges (Gong et al, 2019), resistance in ice floes (Huang et al, 2020(Huang et al, , 2021b, broken ice pieces . In addition, Kim et al (2020) and Sun et al (2022) applied machine learning method to estimate ice resistance based on model test data, while Milaković et al (2020) established machine learning model based on simulation data.…”

Researches on the continuous-wave infrared laser-assisted-load icebreaking

“…The direct ice-breaking methods, such as icebreakers [1][2][3] and explosives [4][5][6], have been widely used to break ice in polar regions. However, these methods cannot fully address the above issues owing to the complicated design and vulnerability of icebreakers, as well as the low efficiency and harmful effects of icebreaking by explosives.…”
