One of the possible uses of a Mono Column Platform is its application as a Hub Platform for people transportation to very far offshore production platforms. Considering a trip from shore to the Hub by a High Speed Vessel (HSV) and by helicopter from the hub to the production platforms, the use of this kind of unit can provide small motions for helicopter operations and a sheltered area for people landing. The use of the moonpool area as an internal dock for the HSV docking was studied in this paper considering an opening in the Mono Column hull to allow the access of the HSV to the moonpool area. The hydrodynamics aspects of the moonpool behavior were assessed considering both experimental and numerical tools and a comparison between these approaches had been also performed.
