| Summary: | Object and purpose of research. This paper discusses ice load simulation for vertical sides of ships compressed by ice. Materials and methods. Experimental data on ice thickness and temperature of upper and lower ice layers obtained under the first stage of Transarktika–2019 project of Russian Federal Service on Hydrometeorology and Environmental Monitoring. A mathematical model for evaluation of design ice compression load parameters. Main results. This study yielded a simulation model for assessment of local ice compression loads on vessels with small or zero flare angle in the midship area. Conclusion. Taking the experience with Akademik Tryoshnikov research vessel as a case study, this paper demonstrates the possibility of assessing and predicting operational ice compression loads on the sides of Severny Polyus self-propelled iceresistant platform or other ships temporarily working as drifting observatories. The results of this work could be used to select ice sheet parameters prior to the drift, so as to ensure trouble-free operation of hull structures. |
