The invention relates to a method of constructing and launching an offshore semi-submersible platform, comprising: a) making said semi-submersible platform in a dry environment by dividing it into a plurality of sub-assemblies each of which comprises at least one of the floating columns and at least one semi-arm of a respective lower structural connection arm; b) providing each sub-assembly in a dry environment with at least one temporary thrust box; c) separately launching in water the individual sub-assemblies; d) adjusting for each sub-assembly the ballast of the respective temporary thrust box so as to obtain a balanced floatation of the sub-assembly; e) bringing the sub-assemblies at the free ends of the respective semi-arms close to each other two-by-two until they are aligned; f) connecting the temporary thrust boxes to each other two-by-two; g) welding the free ends of the semi-arms together; h) removing the temporary thrust boxes.
