碩士 / 國立臺灣海洋大學 / 系統工程暨造船學系 / 100 / To attain wider deck area and larger accommodation space for a high speed ocean-going craft. Which in most cases, the catamaran is suitable for voyaging relatively calm sea. Inevitably if encounters rough sea abruptly, The larger punching motion of much kind hull will generate large relative impact velocity between the cross-deck and wave surface and large slamming load accordingly. The paper is mainly addressed on the comparison of the designed slamming and wave pressure proposed by the CR Rules and DnV Rules taking account for the bow structural damage accident of craft " Ocean LaLa" as an example. Consequently, the slamming stress of the hull structure is analysed by working FEM software package ANSYS. From the results it is found that. It has seen that two designated class rules for the slamming pressure parameters comply with their design load accordingly. For DnV, it is to consider the full-load condition while CR takes light-load condition into account. Calculations have been carried out for the design load, The slamming pressure near CL of each frame is the largest for both Rules, While CR is gradually decrease with the distance from CL, but DnV is downward plunge on the other hand. And it is evident that top ten largest stress distribution by CR concentrates on the fore body while DnV’s scatters on every transverse frame where the values outnumber its counterpart of CR. Investigation has been done by the use of above analysis aiming at the rules on restricted navigation standard.
