This paper presents a summary of an investigation into the effects of hull flexibility when deriving an equivalent service factor for a single passage of a Great Lakes Bulk Carrier from the Canadian Great Lakes to China. The long term wave induced bending moment predicted using traditional three-dimensional rigid body hydrodynamic methods is augmented due to the effects of springing and whipping by including allowances based on two-dimensional hydroelasticity predictions across a range of headings and sea states. The analysis results are correlated with full scale measurements that are available for this ship. By combining the long term ‘rigid body’ wave bending moment with the effects of hydroelasticity, a suitable service factor is derived for a Great Lakes Bulk Carrier travelling from the Canadian Great Lakes to China via the Suez Canal.
