耙吸挖泥船DR68完整稳性及破舱稳性研究

On DR68 intact stability and damage stability of trailing suction hopper dredger

DR68规范对挖泥船完整稳性、破舱稳性的要求与CCS规范具有较大差别,因此对泥舱设置、船体设计也提出不同的要求。文章通过对入级BV及CCS的耙吸挖泥船项目进行对比,简述了该船型稳性计算在满足DR68时需要注意的一些问题。

Since the requirements of DR68 rules on the intact stability and damage stability of dredgers are quite different from CCS rules, there are differences of the arrangement of the mud tank and the hull design. The notices during the stability calculation complying with DR68 rules are presented based on the comparison of the hopper dredgers registered respectively in BV and CCS.
