This ship is a steel multi - purpose cargo vessel with single deck fore raised deck , double - skin , double bottom , double engines , double rudders and aft - engined type , mainly navigating on the pearl river delta hk - macao line , carrying containers as well as bulk cargo 46 . 00m本船为钢质单甲板艏部设升高甲板双壳双层底双机双舵艉机型多用途货船。主要航行于珠三角洲-港澳航线，以载运集装箱为主，也可以载运散杂货物。
When keeping mfh , the force acting on the vessel in the sway direction is lest , this will be of great importance for saving on energy . a technique of searching for mfh based on fuzzy logic is brought up , which adjusts the heading according to the lateral movement of the vessel 由于在最优艏向上横向受力最小，对于节省侧推功率具有很重要的意义，所以本文又提出了一种基于模糊逻辑的、根据横向运动进行的自动艏向寻优方法。
In the full of research , the thesis constructed the dynamic equations of the simplified model , then programmed and computed the feedback gains using lqr method . moreover , the thesis plotted pictures of displacement , velocity , acceleration , bend and shearing force of ship ' s head and middle part in the condition of using cable and not using cable 在研究工作中，首先对船舶的简化模型建立了动力学方程，然后采用线性二次型最优控制方法，编写程序并计算出船体垂向振动固有频率和最优反馈矩阵，得到控制前后船艏以及船舯部的位移、速度、加速度、弯矩和剪力历程图。
In order to resolve the strength problem of 74500dwt bulk carrier on launching way , two aspects of problem are investigated in this report : 1 ) the analysis and calculation of the force act on the hull and the launching way when ship launching ; 2 ) the strength analysis and calculation of bottom structure in forward area during ship launching 为了解决74500吨散货船下水时船体结构的强度问题，本文主要对两方面的内容进行了研究： 1 )船舶纵向下水时的受力分析和滑道反力计算： 2 )艉浮时艏部区域底部结构强度分析计算。
Hou hai bars street , a different culture of life . compared with guangzhou , it is indeed very different . bars in guangzhou , your voice is almost not heard , and in beijing , the bar is like a cultural exchange , chat areas . we pull in guangzhou bars that the use of the culture of bars in beijing , in which all were very happy . where there is the band and belly dance performances beauty . that ' s so good 后海酒吧街,一种不同的生活文化.和馆相比下来,这的确有很大的不同.馆的酒吧, ? ?纳?艏负跏翘?患? ? ,而在北京,酒吧就像是一种文化交流,谈天说地的地方,而我,却把在馆酒吧的文化使于北京酒吧上,个个乐在其中
Fpsu is a permanent floating unit moored on the fixed turret spm , provided with raked stem , skeg , non propeller , non rudder , non - propelled and non brackets , and the living quarters utility facility are on bow , the helideck is on top of the living quarters , the process facility is on midship production deck , the flare is on stern , the bow is moored on the yoke of spm turret . it is a newly - built tanker based floating production storage unit 设有倾斜艏柱船艉设有呆木，无桨无舵，非自航，没有艉框架，居住舱室和公共设施位于船艏直升机甲板位于居住舱室上方，处理设施位于船中部的生产甲板上，天然气放在燃烧塔位于船艉，艏部被系固在单点系泊塔的软钢臂上，是新造的船型浮式生产储油装置。
Using 2 - d strip method and the high - speed slender body theory , the heaving motion responses in regular wave of ship with combined appendage are computed . the results are compared with the results of naked ship hull , and the anti - pitching effect of combined appendage is validated . a method of optimizing the seakeeping is provided from the aspect of the ship hull 因此本文针对船舶耐波性能的优化，提出了一种减纵摇组合附体，将半潜艏和艏鳍安装在常规单体船上，初步阐述了半潜艏和艏鳍的水动力作用机理，并按照二维切片法和高速细长体理论计算了加装组合附体后，船舶在规则波中的垂向稳态运动响应，与裸船体的结果进行了比较，验证组合附体的减摇效果，从船体本身出发提供了?种优化船舶耐波性的方法； 3
