Title:
THREE-DIMENSIONAL TEMPERATURE-SALINITY FIELD ANALYSIS AND FORECASTING METHOD FOR OFFSHORE PLATFORM GUARANTEE
Document Type and Number:
WIPO Patent Application WO/2022/194045
Kind Code:
A1
Abstract:
The present invention provides a three-dimensional temperature-salinity field analysis and forecasting method for offshore platform guarantee, comprising: performing spatial and temporal distribution characteristic analysis and temperature-salinity relationship characteristic research on marine dynamic environment factors on the basis of multi-source marine environment data; on the basis of the spatial and temporal characteristic analysis and the temperature-salinity relationship characteristic research, constructing a statistical forecasting model of the marine dynamic environment factors by using a spatial and temporal empirical orthogonal function method; using a marine environment field dynamic analysis technology to correct a marine environment forecasting field around an offshore platform on the basis of sea temperature and salinity observation data observed by the offshore platform itself; and after a temperature and a salinity are forecasted, adjusting the salinity by using a temperature-salinity relationship curve, so as to keep a temperature-salinity relationship without deviating from climatic state characteristics thereof as much as possible. According to the present invention, the defect of short forecasting timeliness of the marine dynamic environment factors due to meteorological driving timeliness limitation in the conventional numerical forecasting method is overcome, and a high-performance computing platform is not needed in the forecasting process, so that few computing resources are occupied.
