Essay

Object - the process of power interaction of sea waves and currents with different types of SDP. The purpose - improvements of SDP projecting methodology on soft and moving grounds. The methods - physical and mathematical. Novelty - for the first time a mathematical model of interaction of SDP spatial construction with wave and constant flows is made; the model of bed material movement has got the further development, numeral calculating schemes of criteria of SDP stability on ground are improved. Results - the methods of calculating of transitional spatial distribution of speed and pressure, methods of bed movement characteristics near and under supporting base of SDP; structural decision in the form of additional strengthening of submerged drilling platform. Branch - vessel designing.
