Abstract: | This is Part II in a series of papers. Part I (J Mar Sci Technol 13:154–163) deals with an approach employed to construct
a simplified FE model using a 3D compartment model available from the beginning of the ship design process. This paper begins
by describing the limitations of an analytical approach based on shear warping beam theory for assessing torsional strength.
Next, the structural parts of a container ship that have a negligible effect on hull girder bending strength and torsional
strength are determined. This is verified by removing these parts from a conventional FE model and comparing the results obtained
using this modified model with those yielded by the original model. The fore end part, the aft end part and the deck house
are examined. Since these parts have complicated structures and relevant drawings for them are issued later than cargo structure
drawings, modeling them exactly can result in a delay in the completion of the full ship FE model. This paper also verifies
the validity of the simplified FE model built by applying the method proposed in Part I and comparing the results obtained
with it with those given by a conventional full ship FE model. The stresses on hatch coaming top, the maximum diagonal elongations
of the hatch coaming, and the maximum hatch corner movements are evaluated to check the validity of the simplified model. |
