| Bohai Sea is in the mid-latitude and the major oil energy base of china. With the economic development, the status of Bohai Sea in China's national economy is increasing day by day. But ice condition occurs to different degree in Bohai Sea each year, which will directly have an effect on the operation of oil platform, navigation and projects in port and coast. In order to ensure the safety of produce in ice area, it is necessary to study the ice of Liaodong Bay for forecasting and defending the dangerousness of ice.After reading lots of publications, the current dissertation focuses on the sea ice problem in oil production platforms and shipping in the Bohai area, it also explores sea ice monitoring methods and sea ice forecasting technology, researches on the distribution and change of sea ice, estimation of the direction of sea ice flow and changes in sea ice speed. Therefore, it provides a scientific basis for engineering projects for oil production in sea ice areas.My research comes from my winter fieldwork on the eastern bay JZ9-3 oil production platform on radar remote sea ice monitoring and forecasting for two years. The dones following:1.By using the technology of analysis radar image, identify the style of sea ice, denseness, distributing area.2.Through sea current examination, it established forecast technology using radar based flow figures for sea ice. forecasted technology systems for the JZ9-3 oil platform.3.It used a combination of PIV technology, radar monitoring sea ice technology, and computer programming technology to establish a radar-based, remote measuring, sea ice, flow volume, forecasting technology system.
