In order to determine ice loads on the offshore oil and gas structures different ice information is required as an input data. At the present moment there is no unified generally recognized methodology for estimating ice loads and set the main ice parameters. In this relation there appears a question of the ice parameters which need to be investigated. The article attempts to analyze a variety of sources, including standards, on the subject of collection of ice information, required and sufficient for the calculation of ice loads. The article presents the basic steps in the planning of ice information collection, the list of main characteristics and parameters of ice, modern methods of observations and direct measurements of the ice, as well as the ways in which the field tests data of physical and mechanical properties of ice is processed. Particular attention is paid to the anisotropy of ice, integrated assessment of the strength of the ice field, as well as the variability of meteorological conditions.
