The proper composition of offshore wind power exploration equipment is very important to offshore wind power geological drilling， whilst the proper composition of an offshore wind power exploration platform with complete functions is the most important. In order to improve offshore wind power exploration efficiency， safety， and accuracy at water depth more than 35 m， with the platform operation and exploration function design as the fundament， functional design research was conducted on offshore wind exploration jack-up platform equipment in terms of the main technical specifications， lift platform control system design， site geotechnical laboratory. A jack-up exploration platform with double-hole exploration capability has been developed， and achieved good field results with greatly improved efficiency and safety since it was put into operation for two years. It meets the research and development objectives， and provides powerful equipment support for offshore wind power exploration.
