非自航绞吸式挖泥船分舱与拖航安全性探讨

Discussion on the subdivision and towing safety of the non-self propelled cutter-suction dredger

非自航绞吸式挖泥船由于船型的特殊性,拖航中存在较严重的埋首和上浪现象,因而存在进水的危险性.文章针对目前数量较多的两型非自航绞吸式挖泥船,参照法规对一般货船的要求,用不同方法计算分析了此型船舶的破舱稳性,发现在破舱稳性方面存在一些安全隐患.文中对现有此类绞吸船的拖航安全性和今后的设计建造提出了若干建议.

As a result of the specificity of non-self propelled cutter-suction dredger,the appearance of trim by head and green water on deck badly occur during towing. This paper calculates the damage stability for 2 typical non-self propelled cutter suction dredger referring to the SOLAS2004 and International Convention of Load Lines and finds some hidden dangers.Finally,it gives some reasonable suggestions to the subdivision and arrangement of the cutter-suction dredger.
