EXPERIENCE OF USING GNSS MEASUREMENT RESULTS AT IGS STATIONS FOR MONITORING OFFSHORE OIL PLATFORMS ON THE SAKHALIN ISLAND
The article contains a description of the methodology for geodetic monitoring of offshore structures, on the example of the PA-B oil and gas platform located on the northeast shelf of Sakha-lin Island in the Sea of Okhotsk. Monitoring of dangerous industrial assets is crucial for the safe op-eration of the facility, labor protection and environmental. The assessment of the possibility of GNSS monitoring of the stationary marine platform with respect to IGS stations without the use of the coastal network of reference points, while maintaining the accuracy of the coordinates at the centimeter level is performed in the article. The results of experiments on processing GNSS meas-urements with respect to the network of IGS stations using the AUSPOS service are presented. It is shown that this method provides a centimeter level of accuracy and concluded that it can be used for monitoring of marine stationary platforms.
