The aim of this paper is to discuss the use of intermediary objects in the workspace design process of offshore accommodations module. The integration of ergonomics in the design process can lead to better work conditions, more effectiveness in the work process and less health and safety issues. Moreover, it is more efficient in terms of cost if ergonomics is considered from the initial phases of the project, as the potential costs of the redesign, the possible losses and the down-time in the operation of the platform would be more increased. The goal, then, is to discuss the integration of ergonomics and users involvement in the design process of accommodations modules, focusing on the transfer of information from reference situations by the use of intermediary objects during the process. In this paper we will present two tools developed to be used as intermediary object(s) aiming at transferring the experience from the use to the design in the specific field of offshore accommodations module.
