Abstract: Marine engineering structures with anchor mooring system are one of perspective types of the platforms intended for marine service on rather deep-water sites of a shelf. Recently such platforms even more often are offered to be used in ice conditions. In comparison with sleetproof structures of gravitational type such platforms have limited freedom of moving in all directions. At designing of any sleetproof structures it is important an ice loading settlement level's appointment. For constructions with anchor mooring system this question becomes complicated necessity of the influence account of structure dynamics on ice loading's level perceived by it. The results of the model researches with various models of structures executed in Krylov Shipbuilding Research Institute ice basin are resulted in the report. In the ice basin developed technique, allowing to measure some inertial characteristics.

Keywords: anchored engineering structures, ice loading, sleetproof structures, anchor mooring system.
