Another challenge posed by offshore engineering projects is related to the visualization of large engineering simulations. During the conceptual design phase of an industrial plant , several simulations must be carried out to assess the robustness and feasibility of the project. Some of these simulations may require huge computational effort to be processed , such as through the use of computer clusters [Soares et al. 2002 ]. Visualization should as precise as possible in order to provide the user a full understanding of the results.
