| Abstract: | Sea ice has negative influences on the oil/gas platform structure, the nautical transportation and the construction operation during the ice-covered season in the Bohai Sea. The accurate, continuous and real-time field observation of sea ice parameters is very important for the reliability analysis of oil exploration,the validation of sea ice numerical model and the revision of satellite remote sensing data. A digital image processing technology was adopted to obtain the sea ice parameters according to the dynamic distribution characteristics of sea ice in the oil exploration areas of the Bohai Sea. A precise algorithm and an effective software system were developed to determine the ice thickness, the ice velocity and the ice concentration, respectively. In the winter of 2009—2010, this sea ice digital processing program was utilized to observe the ice parameters in the JZ20-2 oil field of Bohai Sea. The ice parameters of thickness, concentration and velocity were obtained of the whole winter. With the field observations, it can be found that the sea ice digital processing program developed has the advantages of convenient operation and high accuracy reliability. With further improvements, it can be an important portion of the field observation of sea ice in the Bohai Sea. |
