“…For the time being, the life time maximum of the vertical bending moment is prescribed by the rules so that there is no need for direct calculations. Since the main objective was to compare the structural response of two ship types within the direct calculation approach, no detailed ultimate strength check was made for this quasi-static part of the analysis and the comparisons were made for WhiSp2 notation only [18].…”

“…It is necessary to mention that the relative importance of hydroelasticity is considered in another paper [18] where the BV Rule Note 583 [13] was followed. The calculation setups for quasi-static calculations and for hydroelastic calculations, [18], are the same; direct comparisons of the relevant quantities and an accurate assessment of the hydroelastic effects are made possible by both setups.…”

SummaryModern sea transportation is characterized by ever larger container ships, which require direct calculation procedures and numerical tools to achieve their reliable structural design. There are different attempts to increase the ship loading capacity, as for instance a container ship with a novel mobile deckhouse enabling her to carry additional number of containers, and at the same time changing basic structural properties of the ship. This paper is related to structural design evaluation of a 19,000 TEU ultra large container ship with novel mobile deckhouse for maximizing cargo capacity, particularly relying on quasi-static approach. The ship structural design is evaluated both for fatigue and extreme loads, where conventional container ship of same particulars is used as a reference. Independent analyses of new and conventional design indicate that conventional container ship shows somewhat better performance from viewpoint of fatigue, while global extreme loading is at the same level.

“…Although the assessment of the example ship was performed at all WhiSp1, 2 and 3 levels, respectively, (please, see [7]) here the results for WhiSp1 and 2 are presented only, due to reason of simplicity. It is also to be mentioned that for the time being, WhiSp3 class notation is only optional.…”

“…Namely, nowadays ultra large container ship with a capacity of 20,000 TEU and length about 400 m are regularly being built. The Rules of classification societies, developed on the basis of long-term experience, are not directly applicable to ULCSs, and therefore direct calculations are necessary for their safe and rational design [6,7,8]. In this context some classification societies have developed guidelines (rule notes) for inclusion of hydroleastic effects, i.e.…”

“…Moreover, for that purpose there are several hydrostructure software available around the world, mainly relying on the same theoretical assumptions, but having incorporated different numerical procedures. Such tools are mostly based on the application of the 3D potential flow theoretical models for fluid flow coupled with the 3D FEM structural models [6,7,8].…”

The trend in modern sea transportation is building of ever larger container vessels, which require application of different numerical tools according to the relevant methodologies, in order to achieve their reliable structural design. The aim of this paper is to review direct strength assessment procedure based on long-term hydro-structure calculations including whipping and springing. As illustrative example, ultra large container ship with a capacity of 19000 TEU is selected and her structural design is evaluated both for fatigue and extreme response, respectively. Mathematical model is based on coupling of the 3D potential flow hydrodynamic model with the 3D FEM structural model. The general hydro-structure code HOMER, developed in Classification Society Bureau Veritas (BV) 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. Ultimate bending capacity was determined by nonlinear finite element analysis. Finally, extreme VBM is determined, and ultimate strength check according to the BV Rule Note NR583 was done.
