Применение технологии лазерного сканирования для контроля состояния защитных сооружений при перекачке нефтепродуктов

Abstract

Laser scanning technology is actively used in various industries. Laser scanning has provenbe a highly precision method of collecting spatial data to solve various tasks. In the oil and gas industry, these are the tasks associated with the study of pipelines for degradation in order to prevent fuel leakage, study of tank state and assessment of their deformations due to various adverse factors, including soil subsidence, timely detection of mechanical damage to oil and gas infrastructure, assessment of the protective structure health, allowing to identify the degree of their reliability in case of emergencies. In order to use the laser scanning technology to identify most of the issues in a timely manner, as well as to assess their possible consequences, various studies are being carried out to develop data collection techniques, to increase the automation degree of the processing the surveying results and their accuracy, to develop methods of creating the final product, demonstrating the result of the processing in the desired form. These modern research trends in the laser scanning technology in order to control the state of protective constructions when transferring oil products are considered. Depending on a laser scanner position when surveying, 3 its types are distinguished: terrestrial, airborne and mobile. Recommendations of applying laser scanning types are discussed. The advantages of applying each type of laser scanning when monitoring various types of protective constructions are indicated. As an example, terrestrial and mobile laser scanning data are given for one site—the oil and gas condensate deposit area. Accuracy of laser scanning data and the reasons for possible errors in their pre-processing are analyzed. It is shown that additional surveying allows detecting changes in the state of various territory objects.
