Wnek, A.D. e Guedes Soares, C. (2012), “Numerical analysis of the shadow effect of an LNG floating platform on an LNG carrier under wind conditions”, Sustainable Maritime Transportation and Exploitation of Sea Resources, Rizzuto & Guedes Soares (eds), Taylor & Francis Group, London, pp. 117-122

The analysis of aerodynamic forces acting on a floating LNG platform and an LNG carrier is the main concern of this paper. The investigation focuses on an important issue in the approaching maneuver of the ship to the platform, which is the effect of platform shadow on the vessel during operation under wind conditions. Two particular cases of models position have been taken into consideration, LNG arrival and departure from the floating platform, in which the wind attacks prior the platform. Results have been obtained using commercial CFD code and compared with experimental measurements performed in a wind tunnel. Numerical and experimental results, presented in a form of coefficients of the drag, lift components and yaw moment, reached approximate agreement.
