In view of the development trend of exploration platform for domestic and abroad offshore engineering,this paper analyzes the avantages and disadvantages of the jack-up and shipborne II exploration platforms and the research results on them.To breaking through the technical bottleneck of geotechnical engineering’s in-situ test implemented by the shipborne platform,and accelerate the integration of China’s offshore exploration quality with international standards,we carry out a research on the in-situ shipboard platform stability.A new design scheme for the shipboard work platform is presented,which expands the mature in-situ test implemented on the land to the water area.
