高速船航行於大海中,其中高速雙體船較適合航行於海況較為平緩的海域中,若是在惡劣海況下航行,船體縱搖運動較大,且橫跨甲板與海浪間的相對衝擊速度及波擊負荷較大。本文以高速雙體客船海洋拉拉號船艏橫跨結構破損事件為例,由於CR與DnV對於海洋拉拉號適航條件之要求不一樣,遂比較CR與DnV法規對波擊壓力及波壓力之設計負荷要求,利用有限元素分析軟體ANSYS進行波擊應力分析。發現在設計負荷方面兩個法規對於波擊壓力的參數規定各有所不同,如DnV主要考慮滿載情況而CR則是考慮輕載情況;在計算後所求得之設計負荷可發現,兩個法規在各船段靠近船體中心(CL)位置之波擊壓力皆為最大,而CR則是隨著遠離CL處其負荷隨之遞減,反觀DnV則是隨著遠離CL處其負荷卻驟降,在分析後可發現CR之前十大應力分佈相當集中,而DnV卻平均分散在各個橫向肋骨上但其應力值皆大於CR。由分析與適航條件比較後可發現DnV高估其航行限制,而CR法規則是波高超過3.5m時橫跨結構才會超過其降伏強度而破裂,顯示出CR在適航標準中相較於DnV是更符合實際情況。
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.
