The objective of this work is to investigate the torsional response of a container ship, with particular consideration of the warping effect. Two different models are investigated. In the first case, the full length model of a ship is analyzed and a distributed load is applied with the use of a novel approach. The model is supported in the torsional centre of the cross-section, which is derived analytically. In the second case, the three cargo hold model is analyzed, where the influence of fore and aft parts of the ship is simulated by ‘end-constraint beams’. A constant, concentrated torsional moment is applied in the shear centre of the fore and aft end cross-section. The structural responses of these two models are obtained and distributions of normal stress across the critical cross-sections are derived. The studies revealed that three cargo hold model subjected to torsional moment underestimates the level of normal stresses caused by the warping effect when compared to the full-length ship model subjected to a distributed load.
