Petrobras, through its Research Center and in cooperation with Universities and Research Institutes, has invested in the development of new concept of platform, aiming to minimize the movements of the structure to work in the field of oil and gas in ultra-deep water. One of these developments is related with a Mono-Column conception provided with a moonpool. In the OMAE2005 Conference, an experimental study of the behavior of this concept was presented, showing the influence of the diameter of the opening of the moonpool base in the heave and pitch motions. A new experimental program was carried out in LabOceano/COPPE/UFRJ, to study the influence of different skirts and the influence of variation of the external diameter along the vertical axis in the behavior of the monocolumn in waves. In this new experimental program a storage unit was tested.
