... by hydroelastic responses took place unexpectedly. Two severe accidents involving large container ships occurred: MSC NAPOLI in 2007 and MOL COMFORT in 2013 (Hirdaris et al., 2023), as shown in Fig. 1. Both vessels were reported to have failed in a hogging condition due to the collapse of the hull girder...

... program developed by authors was used to automatically load the simplified global FEM to analyze the combined bending and torsional strength of hull girder. Three typical arrangements, namely 10 bays (the length of a 40 feet container is called a bay for short), 8 bays and 6 bays in front of the fore...

... ABSTRACT The purpose of the present study is to try to develop a methodology to simply simulate dynamic elasto-plastic structural response of global hull girder of ships subjected to slamming load using a large scale nonlinear finite element model. The main focus is laid on relation between...

... ABSTRACT Curved panels are widely used in fore and aft side shells and circular bilge parts of container ships, which are subjected to complicated loads combination including axial compression, bending and lateral pressure, particularly in the most critical hull girder vertical bending...

..., it is extremely important to study the change of the ultimate strength of marine structures at different temperatures. There are several methods to calculate the ultimate strength of ship hull girder, including progressive destruction method also known as Smith s method, direct calculation method and nonlinear...

... ABSTRACT With the wide use of the high-strength steel and the maximization of container ships, it is evident that stiffness of container vessels decreases sharply, which will cause springing phenomenon, the resulting influence on fatigue strength is inevitable. Firstly hull girder structural...

... Abstract One of the critical issues for large container ships is the vibration of the hull girder due to wave impact which leads to excitation of whipping responses. This study presents analysis guidance to determine values of dynamic bending moments considering the effects due to whipping...

Springing of a ship is the continual hull girder vibration as a consequence of the waves exciting resonant hull girder frequencies. The flexing...

...), the midship sectional scantlings should be determined by the scantling requirements and direct strength analyses. In the scantling requirements of the CSR, there are roughly six categories, the local strength, the hull girder bending strength, the hull girder shear strength, the hull girder buckling strength...
