浅析耙吸挖泥船的稳性计算

Stability Calculation of Trailing Suction Dredger

以某一有泥舱的耙吸挖泥船为例 ,介绍由于泥舱中泥浆的流动对稳性的影响即在大倾角稳性的计算中考虑泥舱内液体 (包括水和泥浆 )的流进及流出对稳性的影响。我室对数艘耙吸挖泥船和部分泥驳采用文中所述的方法 ,计及泥舱中泥对大倾角稳性的影响进行了计算 ,这些计算得到 CCS,BV和英国 L R船级社审查批准 ,现将计算方法结合实例作一介绍 。

This paper gives a brief presentation of the stability computation of trailing suction dredger, taking into account the flow of mud or water in the hopper and especially for the case with large angle of heel. The methods are used for this calculation for a number of trailing suction hopper dredgers and spoil barge with the affection of mud in dredge on stability at large angle. The method has been ratified by CCS and BV.
