【 摘 要 】

Development of hydrocarbons deposits on the continental shelf is connected to the construction of floating and fixed objects functioning in high seas conditions continuously. For the safety analysis of such structures not only the knowledge of ice load values is needed, but also such of their frequency and time-dependent characteristics. The purpose of the present work is further development of methodology for interaction dynamics analysis between ice bodies and Arctic shelf structures presented previously in [1-4]. The paper illustrates the realization of dynamic method of calculation of ice floe deformation and movement upon contact with inclined planes of floating or fixed structures. The presented methodology can be used in the research or project work connected to finding time-dependent characteristics of ice loads, their statistical consistencies and dependency on structures' reaction. The ice field behaviour description algorithm is implemented in the Anchored Structures program. The paper presents some results of the comparison study which prove working efficiency of the presented methodologies.
