Ćorak, M., Parunov, J. e Guedes Soares, C. (2013), “Long-term prediction of combined wave and whipping bending moments of containership”, Analysis and Design of Marine Structure, Guedes Soares & Romanoff (eds), Taylor & Francis Group, London, pp. 3-10

The purpose of the paper is to propose a practical computational procedure for long-term distribution of combined wave and whipping bending moments of containerships. The problem is formulated in the frequency domain using standard engineering tools for load computation: a seakeeping code for rigid-body response and a beam FE model for transient vibratory response. The simplified von Karman approach for bow flare slamming is employed. Correlation between wave and whipping bendingmoments is considered. Long-term distributions of combined bending moments are computed using the standard IACS scatter diagram for the North Atlantic environment and two additional scatter diagrams for custom containership shipping routes. The speed profile required for long-term load prediction is calculated by the seakeeping analysis respecting operability limiting criteria. The procedure is demonstrated on the example of a 9200 TEU containership.
