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。“平均”源于意大利语avaria，代表损失或损害。他们有两种，一种是共同海损一种是单独海损.这些术语是货损方表明货物的灭失或损失的性质。在约克安特卫普规则，1974给出了一个清晰明确的共同海损规则： "there is a general average act when,and only when ,any extraordinary sacrifice or expenditure is intentionally and reasonably made or incurred for the common safety for the purpose of preserving from peril the property involved in a common maritime adventure." 当共同海损的情形出现时，只有卓有成效的努力和付出以确保共同的安全，做出任何特殊牺牲或费用，有意而合理地为了航程中的财产脱离危险做出的行为。” although the idea of general average is simple in a real situation the practical application of it can be complicated.General average must be distinguished from particular average 尽管共同海损的想法是简单的在一个真实的情况可以复杂的实际应用。共同海损必须区别于单独海损 the general average declaration is normally made by the shipowner and must be made before the delivery of the cargo. Shipowners usually will release the cargo when the other interested parties to the adventure provide suitable security(General Average Deposit or Bond ),sufficient to cover their contributions. 共同海损声明必须由船东在货物交接之前做出，船东通常会处理货物,当其他感兴趣的各方愿意提供合适的安全保障(共同海损存款或债券),足以弥补他们的损失。全能易得 in shipping business the word "claim" denotes a means of cargo-owners who demand compensation from the carrer or shipowners for the loss of or damage to cargo incurred in transit .In accordance with international practices,if the goods on arrival at the port of destination are found short,damaged or lost,not in conformity with what is stated in the clean bill of lading,the consignee may give in writing a notice of loss or damage to the carrier or his agents there to indicate his intention

Chapter 1 Ship Design（船舶设计） Lesson 2 Ships Categorized（船舶分类） 2.1 Introduction（介绍） The forms a ship can take are innumerable. 一艘船能采用的外形是不可胜数的 A vessel might appear to be a sleek seagoing hotel carrying passengers along to some exotic destination; a floating fortress bristling with missile launchers; 。or an elongated box transporting tanks of crude oil and topped with complex pipe connections. 一艘船可以看做是将乘客一直运送到外国目的地的优美的远航宾馆。竖立有导弹发射架的水面堡垒及甲板上铺盖有复杂管系的加长罐装原油运输轮 None of these descriptions of external appearance, however, does justice to the ship system as a whole and integrated unit所有这些外部特点的描述都不能说明船舶系统是一个总的集合体 self-sufficient,seaworthy, and adequately stable in its function as a secure habitat for crew and cargo. ——船员和货物的安全性功能：自给自足，适航，足够稳定。 This is the concept that the naval architect keeps in mind when designing the ship and that provides the basis for subsequent discussions, not only in this chapter but throughout the entire book.这是一个造船工程师设计船舶使必须记住的、能为以后讨论提供根据的观念，不仅涉及本章也贯穿全书。 In order to discuss naval architecture,it is helpful to place ships in certain categories. For purposes of this text, ships are classified according to their means of physical support and their designed purposes.将船舶分成一些特定的种类来讨论造船工程是有好处的。本文的目的就是根据船舶物理支撑方式和设计目的来将它们分类。

Lesson One The Naval Architect A naval architect asked to design a ship may receive his instructions in a form ranging from such simple requirements as “an oil tanker to carry 100 000 tons deadweight at 15 knots” to a fully detailed specification of precisely planned requirements. He is usually required to prepare a design for a vessel that must carry a certain weight of cargo (or number of passengers ) at a specified speed with particular reference to trade requirement; high-density cargoes, such as machinery, require little hold capacity, while the reverse is true for low-density cargoes, such as grain. Deadweight is defined as weight of cargo plus fuel and consumable stores, and lightweight as the weight of the hull, including machinery and equipment. The designer must choose dimensions such that the displacement of the vessel is equal to the sum of the dead weight and the lightweight tonnages. The fineness of the hull must be appropriate to the speed. The draft------which is governed by freeboard rules------enables the depth to be determined to a first approximation. After selecting tentative values of length, breadth, depth, draft, and displacement, the designer must achieve a weight balance. He must also select a moment balance because centres of gravity in both longitudinal and vertical directions must provide satisfactory trim and stability. Additionally, he must estimate the shaft horsepower required for the specified speed; this determines the weight of machinery. The strength of the hull must be adequate for the service intended, detailed scantlings (frame dimensions and plate thicknesses ) can be obtained from the rules of the classification society. These scantings determine the requisite weight of hull steel. The vessel should possess satisfactory steering characteristics, freedom from troublesome vibration, and should comply with the many varied requirements of international regulations. Possessing an attractive appearance, the ship should have the minimum net register tonnage, the factor on which harbour and other dues are based. (The gross tonnage represents the volume of all closed-in spaces above the inner bottom. The net tonnage is the gross tonnage minus certain deductible spaces that do not produce revenue. Net tonnage can therefore be regarded as a measure of the earning capacity of the ship, hence its use as a basis for harbour and docking charges. ) Passenger vessels must satisfy a standard of bulkhead subdivision that will ensure adequate stability under specified conditions if the hull is pierced accidentally or through collision. Compromise plays a considerable part in producing a satisfactory design. A naval architect must be a master of approximations. If the required design closely resembles that of a ship already built for which full information is available, the designer can calculate the effects of differences between this ship and the projected ship. If, however, this information is not available, he must first produce coefficients based upon experience and, after refining them, check the results by calculation. Training There are four major requirements for a good naval architect. The first is a clear understanding of the fundamental principles of applied science, particularly those aspects of science that have direct application to ships------mathematics, physics, mechanics, fluid mechanics, materials, structural strength, stability, resistance, and propulsion. The second is a detailed knowledge of past and present practice in shipbuilding. The third is personal experience of accepted methods in the design, construction, and operation of ships; and the fourth, and perhaps most important, is an aptitude for tackling new technical problems and of devising practical solutions. The professional training of naval architects differs widely in the various maritime countries. Unimany universities and polytechnic schools; such academic training must be supplemented by practical experience in a shipyard. Trends in design The introduction of calculating machines and computers has facilitated the complex calculations required in

The spatial scheduling problem is to schedule a set of jobs, of which each requires its physical space in a restricted space. This problem is complicated because both the scheduling of assemblies with different due dates and earliest starting times and the spatial allocation of blocks with different sizes and loads must be considered simultaneously. This problem under consideration aims to the minimization of both the makespan and the load balance and includes various real-world constraints, which includes the possible directional rotation of blocks, the existence of symmetric blocks, and the assignment of some blocks to designated workplaces or work teams. The problem is formulated as a mixed integer programming (MIP) model and solved by a commercially available solver. A two-stage heuristic algorithm has been developed to use dispatching priority rules and a diagonal fill space allocation method, which is a modification of bottom-left-fill space allocation method. The comparison and computational results shows the proposed MIP model accommodates various constraints and the proposed heuristic algorithm solves the spatial scheduling
