Abstract

P016 DUAL-FREQUENCY SUBBOTTOM PROFILING FOR THE EVALUATION OF SAFETY OF OFFSHORE STRUCTURES P-wave velocity m/s 1 Summary The application of dual-frequency continuous subbottom profiling for the evaluation of the offshore structure safety conditions during their installation and exploitation is considered. The developed set of equipment is used during the stages of site investigations for the construction of offshore drilling platforms and underwater pipelines and their subsequent geological-geophysical monitoring. The profiling modes in different frequency ranges are used for the identification and outlining of components of the geological environment that are hazardous or unfavourable for offshore structures. In combination with geotechnical
