Clarindo, G. and Guedes Soares, C. (2021), “Derivation of environmental contour by direct Monte Carlo techniques”, Developments in Maritime Technology and Engineering, Guedes Soares, C. & Santos T.A., (Eds.), Taylor and Francis, London, UK, Vol 2, pp. 549-558.

This paper presents the main steps of environmental contours derivation and the computing steps with a direct and alternative technique. The environmental contours are a widely applied method in engineering and especially in ocean engineering to estimate the extreme conditions and structural system response. A wide variety of environmental contour construction methods have already been proposed for marine structures. In general, they can help to predict the extreme and critical met-ocean combinations at some location allowing the engineers to reach the best structural reliability recommendations. This work derives the extreme environmental contours based on Direct Monte Carlo simulations of fitted joint environmental variables, thus concluding the main steps in the process of environmental contours derivation. The Direct Monte Carlo is tested in a robust and consistent dataset. Some preliminary comparisons with IFORM are made and the Direct Monte Carlo presents a good approximation.
