Gravity type oil platforms at shallow marine coastal areas are currently used for oil extraction. Processes of bottom soil erosion near foundations of those platforms and analyses of their stability problems are of great interest. Laboratory-based experiments, seminatural physics experiments and mathematical model approaches have been recently used to study those problems. Papers [1-3] show the results of many experimental investigations and computational investigations of noncohesive soil erosion near foundation of the platform “Prirazlomnaya”, comparative tables of laboratory experiments and computational experiments, analysis of different wave modes of fluid flow impact on bottom material particle transportation. Fluid flow mode is supposed to be laminar. The paper studies flow developed turbulence impact on erosions and soil load development near foundations of gravity type oil platform by using experimental and computational investigations.
