Abstract


The mathematical model using is presented of cohesionless soil scour near foundations of marine gravity-type platforms from currents impact. In addition to this, numerical studies are also performed for different parameters of such impact. Furthermore, experimental investigations are executed in hydrowave basin with a platform model. In this work, scour areas and scour holes depths are obtained near the platform foundation, then comparison is performed of numerical and experimental studies.
