Sažetak
The trend in modern sea transportation is building of ever larger container vessels, which require application of different direct calculation methodologies and numerical tools to achieve their reliable structural design. In this paper structural design of 19000 TEU class ultra large container carrier is evaluated both for fatigue and extreme response within so called WhiSp1 and 2 methodologies, respectively. WhiSp1 implies evaluation of fatigue life of selected structural details with linear springing effect included, while within WhiSp2 the ultimate strength check is done considering slamming induced whipping. Mathematical model is based on the application of the 3D potential flow theoretical models coupled with the 3D FEM structural models. The general hydro-structure code HOMER, developed in Bureau Veritas is used. Stress RAOs of selected structural details are obtained for full scatted diagram by the top-down procedure, and further used to assess their fatigue lives. Linear long term analysis is performed to define most contributing sea state to the vertical bending moment (VMB). Whipping response is computed on so called increased design sea state in time domain. Finally, extreme VBM is determined, and ultimate strength check is done. Preliminary results indicate that analyzed ship satisfies both WhiSp1 and 2 criterion, respectively.
