The paper presents the main features of a computer system for support the analysis of investment in ships, based on Real Options Analysis - ROA and Monte Carlo simulation. ROA has been increasingly adopted for large projects, subject to high degree of uncertainty and presenting significant managerial flexibility. Despite of the recognized applicability in shipping, ROA is not normally applied, mainly because of the technical and operational complexity. The system aims at overcoming these problems, and was designed to make feasible ROA application by non-specialists. The proposed ROA methodology for shipbuilding projects may incorporate options of abandon, defer or lay-up. The models for stochastic series of time-charter rates and ship prices, necessary for ROA, may be automatically or interactively selected. The system also allows the interactive definition of the cash flow structure, including the managerial options to be considered. The architecture of the computer system and the user interface are discussed.
