Engineering Contradiction Analysis
1Reliability
If traditional methods are used for determining wind turbine installation locations, then the process is simpler and faster, but the results are time-consuming, subjective, and prone to errors
Solution Approach 1:
The determination process is segmented into distinct phases: data acquisition from multiple sources (seismic, borehole, geotechnical), data processing and conditioning, subsurface model generation, and installation site selection. This segmentation allows parallel processing of different data types and reduces overall time while improving reliability through systematic analysis of each component
Solution Approach 2:
Comprehensive subsurface data is collected and processed in advance before actual turbine installation decisions are made. Ground models are generated preliminarily to identify suitable locations, reducing on-site decision time and improving accuracy through pre-analyzed geological conditions
2Loss of information
If comprehensive geotechnical and geophysical data integration is performed, then subsurface understanding is improved, but system complexity increases
Solution Approach 1:
A centralized ground model serves as an intermediary that integrates diverse data sources including seismic data, borehole measurements, and geotechnical properties. This intermediary model synthesizes information from multiple complex systems into a unified subsurface representation, reducing the complexity of direct multi-source integration while preserving complete subsurface information
Solution Approach 2:
The ground model system performs multiple functions: it stores subsurface data, processes different data types, generates geological interpretations, and supports installation site selection. This multi-functionality consolidates what would otherwise require separate systems into a single integrated platform, managing complexity while maximizing information completeness
Data Source
AI summary
A method for determining locations for wind turbine installations at a site. The method includes receiving data from a site, wherein the data includes geotechnical data such as borehole measurements and geophysical data such as high resolution shallow seismic data, magnetometer data, and sonar images. The method includes conditioning the received data by interpreting the received data for key soil boundaries and mechanical properties that are related to a shallow subsurface of the site. The method also includes generating a ground model of the site. The ground model may be continuously updated with newly received data or interpretation updates. The ground model may also be displayed on a screen. The method also includes performing a site action based on the ground model including selecting where to install one or more heavy wind turbine structures within the site.
