At the time of noting a protest the master should reserve the right to extend it at time and place convenient , because at the time protest is noted the full extent of the loss or damage may not be well ascertained .in foreign ports,protest should be noted before the port authority or a notary public ,or before the consular office representing the country in which the ship is registered.when such action is taken ,it is necessary to bring the log book and several crewmembers as witnesses. in many cases they are essential to the establishment of a claim in the future.在提出声明的时候船长应保留权利以使调查货物灭失和损失的时间和地点比较方便，因为当声明提出时，货物的灭失和损失是不确定的。

在外国港口，声明应该向港口当局或者公证人在或者船舶登记国的领事馆提出，当声明提出后需要带着船舶日志及几个船员作为目击证人。

在许多情况下，他们是在未来提出索赔的基础。

In shipping and marine insurance terminology ,"average"is a word meaning partial loss or damage sustained by a vessel and/or cargo during the couse of a voyage. the word"average"originated from the Italian word avaria ,meaning loss or damage . there are two kind of average and particular average.these terms indicate the character of the loss or damage ,and who bears that loss or damage .the YorkAntwerp Rules,1974 gives a clear and definite of a general average:在航运和海上保险术语中，“平均”一词的意义代表部分灭失或损害持续的时间是在船舶航行或货物的运输过程中。

第一章船舶设计第一课介绍翻译人员：1.1 定义‘基本设计’是专业术语，它决定船舶主要性能，影响船舶造价和功能。

因此，基本设计包括选择船型尺寸，船体形状，动力设备（数量和类型），初步布置船体机械设备和主要结构。

合适的选择方案能保证达到目标要求，比如良好的耐波性和操纵性，预期航速，续航力，货舱舱容和总载重量。

而且，包括校核使之达到货物装卸能力要求，舱室要求，各项宾馆服务标准，分舱要求，干舷和吨位丈量标准,所有这些都是盈利运输船舶，工业或服务系统用船，所必须考虑的部分因素。

基本设计包括概念设计和初步设计，它决定了船舶主要性能，为价格初步估计做了准备。

在整个设计过程中，基本设计完成后，就要进行合同设计和详细设计。

正如合同设计这名暗示的那样，它为船厂投标和承接合同订单数准备合适的合同计划和规范。

完整的合同计划和规范内容很清晰且足够详细，以避免发生代价高昂的偶发性事件，保护投标方免受模糊不清的描述要求的影响。

详细设计是进一步完善合同方案，它是船厂的责任。

合同方案需要为实际船舶建造准备施工图。

为了能够进行基本设计，每个人都必须了解整个设计流程。

这中的四个步骤用 Ecans 的 1959 年的设计螺旋循环方式图说明了，设计螺旋循环方式是一种含盖从目标需求到详细设计的迭代过程，如图 1.1。

下面将进一步详述这些步骤： a.概念设计。

概念设计是最开始的工作，是讲目标需求转换成造船工程参数。

一般来说，它包含技术可行性研究，来决定目标船舶的基本参数。

例如船厂，船宽，船深，吃水，丰满度，动力能源设备，或一些代用特性，所有这些都是为了满足达到设计航速，航区，货舱舱容和总载重量的要求。

它包括空船重量的初步估计，一般通过特性曲线，公式，或经验确定。

在该阶段，备选设计一般由参数研究法来分析，以确定最经济的设计方案或任何其他必须考虑的决定性因素。

所选择的概念设计用作今后获得建造费用的讨论文件，建造费用决定是否进展下一阶段工作：初步设计。

第一章船舶设计第一课引言1.1定义术语“基本设计”是指对影响造价和性能的船舶主要参数的确定。

因此，基本设计包括船舶主尺度、船体线型、动力（数量和种类）的选取，以及船体、机械设备和主要结构的布置。

恰当的选取可保证达到设计任务书的要求，例如良好的耐波性能，操纵性，预期的速度，续航力，舱容和载重量。

进一步讲，基本设计还包括校核和修改，以满足货物装卸能力，居位舱，客房设施，分舱和稳性标准，干舷和吨位测量，所有这些都是将船舶当成运输、工业化或服务系统的一部分。

基本设计包含概念设计和初步设计，可以确定船舶主要技术参数，为造价初步估计做准备。

再整个设计过程中，基本设计之后紧接着就是合同设计和详细设计。

合同设计，顾名思义，需要做出图纸和详细说明书，以便船厂去投标和签约。

一套良好的合同图纸和详细说明书应当是非常清晰和详细的，以避免高成本的偶然性项目，并使投标者不出现模糊不请的或不充分的描述。

详细设计师船厂进一步完善合同设计的重要任务，以准备施工图用于船舶实际建造。

了解整个设计顺序对任何做基本设计的人都是必要的。

设计的4个阶段用设计螺线图表示，如图1所示，是从任务书要求到详细设计的循环工作过程，这4个阶段在下面作详细叙述a 概念设计概念设计作为整个设计的第一阶段，是将任务书要求转换为船舶建造工程参数。

它基本上包括技术可行性研究，确定船舶的基本参数如船长，船宽，船深，吃水，丰满度，动力，或可供选择的参数方案，所以这些应满足所要求的航速，航程，货舱舱容和载重量。

这包括基于曲线、公式经验而进行的空船重量初步估算。

在这一阶段，通常进过参数分析而进行多方案设计以寻求最经济的设计方案，或者任何其它控制也纳入考虑之中以确定最优方案。

确定下来的概念设计就做为讨论文件以获得近似的建造成本，不论是否启动下一阶段的设计——初步设计。

b 初步设计船舶的初步设计将进一步优化那些影响造价和性能的传播主要参数。

一些控制参数如船长，船宽，功率和载重量，在该阶段完成之后不宜再变更。

船舶与海洋工程论文中英文资料外文翻译文献

中英文资料外文翻译文献A Simple Prediction Formula of Roll Damping of Conventional Cargo Ships on the Basis of lkeda's Method and Its LimitationSince the roll damping of ships has significant effects of viscosity, it is difficult to calculate it theoretically. Therefore, experimental results or some prediction methods are used to get the roll damping in design stage of ships. Among some prediction methods, Ikeda’s one is widely used in many ship motion computer programs. Using the method, the roll damping of various ship hulls with various bilge keels can be calculated to investigate its characteristics. To calculate the roil damping of each ship, detailed data of the ship are needed to input. Therefore, a simpler prediction method is expected in primary design stage. Such a simple method must be useful to validate the results obtained by a computer code to predict it on the basis of Ikeda，s method, too. On the basis of the predicted roll damping by Ikeda’s method for various ships, a very simple prediction formula of the roll damping of ships is deduced in the present paper. Ship hull forms are systematically changed by changing length, beam, draft, mid-ship sectional coefficient and prismatic coefficient. It is found, however, that this simple formula can not be used for ships that have high position of the center of gravity. A modified method to improve accuracy for such ships is proposed.Key words: Roll damping, simple prediction formula, wave component, eddy component, bilge keel component.IntroductionIn 1970s, strip methods for predicting ship motions in 5-degree of freedoms in waves have been established. The methods are based on potential flow theories (Ursell-Tasai method, source distribution method and so on), and can predict pitch, heave, sway and yaw motions of ships in waves in fairly good accuracy. In roll motion, however, the strip methods do not work well because of significant viscous effects on the roll damping. Therefore, some empirical formulas or experimental dataare used to predict the roll damping in the strip methods.To improve the prediction of roll motions by these strip methods, one of the authors carried out a research project to develop a roll damping prediction method which has the same concept and the same order of accuracy as the strip methods which are based on hydrodynamic forces acting on strips. The review of the prediction method was made by Himeno [5] and Ikeda [6，7] with the computer program.The prediction method, which is now called Ikeda’s method, divides the roll damping into the frictional (BF), the wave (Bw)，the eddy (Be) and the bilge keel (Bbk) components at zero forward speed, and at forward speed, the lift (Bi) is added. Increases of wave and friction components due to advance speed are also corrected on the basis of experimental results. Then the roll damping coefficient B44 (= roll damping moment (kgfm)/roll angular velocity (rad/sec)) can be expressed as follows: B44 B bk (1)At zero forward speed, each component except the friction and lift components are predicted for each cross section with unit length and the predicted values are summed up along the ship length. The friction component is predicted by Kato’s formula for a three-dimensional ship shape. Modification functions for predicting the forward speed effects on the roll damping components are developed for the friction, wave and eddy components. The computer program of the method was published, and the method has been widely used.For these 30 years, the original Ikeda’s method developed for conven tional cargo ships has been improved to apply many kinds of ships, for examples, more slender and round ships, fishing boats, barges, ships with skegs and so on. The original method is also widely used. However, sometimes, different conclusions of roll mot ions were derived even though the same Ikeda’s method was used in the calculations. Then, to check the accuracy of the computer programs of the same Ikeda’s method, a more simple prediction method with the almost same accuracy as the Ikeda’s original one h as been expected to be developed. It is said that in design stages of ships, Ikeda’s method is too complicated to use. To meet these needs, a simple roll damping prediction method was deduced by using regression analysis [8].Previous Prediction FormulaThe simple prediction formula proposed in previous paper can not be used for modem ships that have high position of center of gravity or long natural roll period such as large passenger ships with relatively flat hull shape. In order to investigate its limitation, the authors compared the result of this prediction method with original Ikeda’s one while out of its calculating limitation. Fig. 1 shows the result of the comparison with their method of roll damping. The upper one is on the condition that the center of gravity is low and the lower one on the condition that the center of gravity is high.From this figure, the roll damping estimated by this prediction formula is in good agreement with the roll damping calculated by the Ikeda’s method for low positi on of center of gravity, but the error margin grows for the high position of center of gravity. The results suggest that the previous prediction formula is necessary to be revised. Methodical Series ShipsModified prediction formula will be developed on the basis of the predicted results by Ikeda’s method using the methodical series ships. This series ships are constructed based on the Taylor Standard Series and its hull shapes are methodically changed by changing length, beam, draft, midship sectional coefficient and longitudinal prismatic coefficient. The geometries of the series ships are given by the following equations. Proposal of New Prediction Method of Roll DampingIn this chapter, the characteristics of each component of the roll damping, the frictional, the wave, the eddy and the bilge keel components at zero advanced speed, are discussed, and a simple prediction formula of each component is developed.As well known, the wave component of the roll damping for a two-dimensional cross section can be calculated by potential flow theories in fairly good accuracy. In Ikeda's method, the wave damping of a strip section is not calculated and the calculated values by any potential flow theories are used as the wave damping.reason why viscous effects are significant in only roll damping can be explained as follows. Fig. 4 shows the wave component of the roll damping for 2-D sections calculated by a potential flow theory.ConclusionsA simple prediction method of the roll damping of ships is developed on the basis of the Ikeda’s original prediction method which was developed in the same concept as a strip method for calculating ship motions in waves. Using the data of a ship, B/d, Cb，Cm, OG/d, G)，bBK/B, Ibk/Lpp，(pa, the roll damping of a ship can be approx imately predicted. Moreover, the limit of application of Ikeda’s prediction method to modern ships that have buttock flow stern is demonstrated by the model experiment. The computer program of the method can be downloaded from the Home Page of Ikeda’s Labo (AcknowledgmentsThis work was supported by the Grant-in Aid for Scientific Research of the Japan Society for Promotion of Science (No. 18360415).The authors wish to express sincere appreciation to Prof. N.

1术语“基本设计”是指对影响造价和性能的船舶主要参数的确定。

因此，基本设计包括船舶主尺度、船体线型、动力（数量和种类）的选取，以及船体、机械设备和主要结构的布置。

恰当的选取可保证达到设计任务书的要求，例如良好的耐波性能，操纵性，预期的速度，续航力，舱容和载重量。

2船舶的形状是多种多样的，一艘船可能是一个豪华的海上酒店，载着旅客游世界；也可能是一个浮动的堡垒，扬起导弹发射架；也可能是一个长箱，运输原油，甲板上布满了复杂的管线。

这些外部特征的介绍绝不能准确地描述完整的集成的船舶系统——自给自足的，适航的和有足够稳性的，能为船员和货物提供一个安全的处所。

这一概念是造船师再设计船舶时必须牢记再心中的，也是今后讨论的基础，不仅仅是在本案中，而是贯穿整本书。

3在仔细研究造船工程各种分支之前，定义一些术语是重要的，一便后面章节学习中使用。

这一章的目的是解释这些术语，并让读者熟悉他们。

首先，应考虑测量船舶尺寸的尺度，它们就是“主尺度”。

正像任何固体一样，船舶要求三维尺度来定义她的尺度，包括船长、船宽和船深。

这些将依次讨论。

4典型船舶的主要部分极其术语如图4.1所示。

首先，因为上层建筑和甲板室（对船舶性能来说）影响很小，故忽略不计船体当成各个方向都是曲线的中空物体，上层覆盖的是水密甲板。

大多数船只有一个对称面，称为中线面，作为船舶的主要参考面。

船体形状被该平面切开后就是纵剖面或总剖图。

设计水线面是垂直于中线面的平面，去做水平或近于水平的参考面。

它可以也可能不平行于龙骨。

同时垂直中线面和设计水线面的平面称为横剖面，通常它关于中线对称与中线面垂直并与设计水线面平行的称为水线面，它还可能位于水中也可能不是，通常是关于纵中线对称的，水线面不必平行于龙骨。

因此，通过相互垂直平面的剖切，船体曲面形状就很好地展示给我们。

第一课(陈锦航)商船的存在是为了把货物安全、快速、经济地通过水路运输出去。

因为地球的表面的大部分（大约 3/5）为水覆盖，这就使我们有理由相信，商船在未来的很多世纪将继续使用下去。

船及船上的货物和成员能够反映国际生活的很多方面。

国际航行的一些特点，如天气、气候变化，货物装卸设备的布置和国际法规将在下面介绍。

船舶有各种各样的形式，它根据三个主要因素来完成其功能——货物的种类，结构形式和使用的材料，以及营运的区域。

现今，有三种主要类型的运输船型：杂货船、液货船和客船。

杂货船总的讲是作为运输船，同时也有几种特殊的船型用于运输以单元为基础或单元化了的货物。

例如：集装箱船、托盘货船和液装船。

液货船为了适于运输石油、石油产品和液化气等货物有着特殊的结构。

客船包括通常意义上讲的固定航线的客船和渡船。

结构形式将影响货物运输，在某种程度上也影响船的内部特征。

结构的主要形式指为了加强外板而进行的骨架布置形式，有三种结构形式：纵骨架式、横骨架式、混合骨架式。

低碳钢、特种钢、铝和其它材料的运用也影响着船的特征。

杂货船一般是横骨架式或混合骨架式，通常用的材料是低碳钢的型材和板材。

大多数液货船采用纵骨架式或混合骨架式，大型船舶采用高强度钢。

客轮有很大的上层建筑面积，采用轻金属材料和合金如铝来减轻上层建筑的重量。

贸易范围、航行区域，可能遇到的最恶劣的气候，这些在一条船设计时就必须有所考虑。

海船要求有几个液箱，用来装载淡水和燃油。

稳性和纵倾必须满足航行区域的天气要求。

海船的结构强度抵抗波浪冲击的能力必须比内河船大很多。

船在设计中和营运时最重要的是它的安全性，并把它放在首要位置，因此，船必须具有适航性。

这同船的很多方面有联系，如：船在任何天气条件下必须保持一定的漂浮能力，船在破损时必须也保持有一定的漂浮能力，除非受到最严重的破损。

在各种海况下保持稳定。

有关适航性的一些结构和规则将在以后的章节中阐述。

稳性和其它设计在由 W.Muckie 所著的《轮机工程师船体结构》中有详细讲解。
