双体甲板运输船波浪载荷

以某双体甲板运输船为例,使用DNV船级社的SESAM软件对其波浪载荷进行直接计算分析,并对比分析了采用“规范方法”与“直接计算方法”得到的波浪载荷值。结果表明,该双体甲板运输船属于低速排水型船,其波浪载荷的计算方法与高速双体船差别较大,“规范方法”主要适用于高速双体船及尺度较小的低速双体船。对于船长为60m及以上的低速双体船,采用“直接计算方法”更能准确地计算出其波浪载荷。

Wave Load of Double Deck Transport Ship

Taking a catamaran transport ship as an example,the wave load of DNV Classification Society is used to directly calculate and analyze the wave load,and the wave load values obtained by using the "standard method" and "direct calculation method" are compared and analyzed.The results show that the catamaran deck carrier is a low-speed displacement ship.The calculation method of wave load is quite different from that of high-speed catamarans.The "standard method" is mainly applicable to high-speed catamarans and small-scale low-speed catamarans.For low speed catamarans with a length of 60m and above,the wave load can only be calculated accurately by using the"direct calculation method".
