Lesson 1 Introduction 1.1 Definition The term basic design (基本设计) refers to determination of major ship(大型船舶) characteristics affecting cost and performance. Thus, basic design(基本设计) includes the selection of ship dimensions, hull form(船形,船体外 形), power (amount and type), preliminary arrangement of hull and machinery, and major structure. Proper selections assure the attainment of the mission requirements such as good sea keeping performance(耐波性能), maneuverability(操纵性), the desire speed, endurance(续航力,全功率工作时间), cargo capacity, and deadweight(总载重量). Furthermore, it includes checks and modifications for achievement of required cargo handing capability, quarters, hotel services, subdivision(分舱) and stability(稳性) standards, freeboard(干舷) and tonnage(吨位) measurement; all while considering the ship as part of a profitable transportation, industrial(实船试验), or service system.
o Basic design(基本设计)encompasses both concept design(概念设计) and preliminary design(初步设计). It results in the determination of major shop characteristics, permitting the preparation of initial cost estimates, In the overall design process, basic design(基本设计) if followed by contact design and detail design(详细设计). Contract design(合同设计), as its name implies, develops plans and specifications suitable for shipyard bidding and contract award. Well prepared contract plans and specifications will be clear and in sufficient detail to avoid costly contingency items and protect bidders (投标者)from obscure or inadequate description of requirements. Detail design(详细设计) is the shipyard's responsibility for further developing the contract plans as required to prepare shop drawings used for the actual constructions of the vessel. o An understanding of the entire design sequence is essential to anyone seeking to develop a basic design(基本设计). The four steps involved are illustrated in the Design spiral(设 计螺旋循环方式),Evans(1959) as an iterative process(迭代过程) working from mission requirements to a detail design(详细设计), Fig.1.1. These steps are amplified further below: o a. Concept design (概念设计) The very first effort, concept design(概念设计), translates the mission requirements into naval architectural and engineering characteristics. Essentially, it embodies technical feasibility studies to determine such fundamental elements of the proposed ship as length, beam(船宽,梁), depth(船深), draft(吃水), fullness(丰满度), power, or alternative sets of characteristics, all of which meet the required speed, range, cargo cubic(货舱舱容,载货)ign solution or whatever other controlling parameters are considered determinant. The selected concept design(概念设计) then is used as a talking paper(讨论文件) for obtaining approximate construction costs, which often determine whether or not to initiate the next level of development, the Preliminary design(初步设计).
b. Preliminary design (初步设计) A ship' s preliminary design(初步设计) further refines the major ship(大型船舶)

c. Contract design (合同设计) The contract design(合同设计) stage yields a set of plans and specifications which form an integral part of the shipbuilding contract document. It encompasses one or more loops around the design spiral(设计螺旋循环方式), thereby further refining the preliminary design(初步设计). This stage delineates more precisely such features as hull form(船形,船体外形) based on a faired set of lines(经过光顺处理的一套型线), powering based on model testing, sea keeping and maneuvering characteristics, the effect of number of propellers on hull form(船形,船体外形), structural details, use of different types of steel, spacing and type of frame(船肋骨,框架)s. Paramount, among the contract design(合同设计) features, is a weight and center of gravity estimate taking into account the location and weight of each major item in the ship. The final general arrangement is also developed during this stage. This fixes the overall volumes and areas of cargo, machinery, stores, fuel oil, fresh water(淡水), living and utility spaces(居住与公用 舱室) and their interrelationship, as well as their relationship to other features such as cargo handling(货物装卸) equipment, and machinery components. The accompanying specifications delineate quality standards of hull and outfit(舾装) and the anticipated performance for each item of machinery and equipment. They describe the tests and trials (实船试验)that shall be performed successfully in order that the vessel will be considered acceptable.

Table 1.1 shows a typical list of plans developed in the contract design(合同设计) of a major ship(大型船舶). Smaller, less complex vessels may not require every plan listed for adequate definition, but the list does provide an indication of the level of 萏 metal workers (金属工), machinery vendors (机械主机 卖方), pipe fitters (管装工), etc. As such, they are not considered to be a part of the basic design(基本设计) process. One unique element to consider in this stage of the design is that up to this point, each phase of the design is passed from one engineering group to another. At this stage the interchange is from engineer to artisan(技工), that is, the engineer's product at this point is no longer to be interpreted, adjusted, or corrected by any other enginee carries preliminary design(初步设计) to the point where there is reasonable assurance that the major features have been determined with sufficient dependability to allow the orderly development of contact plans and specification. This development will form a basis to obtain shipyard prices within a predetermined price range that will result in an efficient ship with the requisite performance characteristics.
1.2 General Aspects
THE late 1960's and 1970's saw a number of major new development which in one way or another had and impact on the general basic design(基本设计) problem. Among the most significant was the computer. While the computer affects how basic design is preformed other changes have impacted on what constitutes the basic design problem. For example, one revolutionary development was the change from breakbulk (件杂货) to containerized cargos in the liner traders (定期班轮营运业). Other developments in other ship types created similar new considerations. For tankers (油轮), size mushroomed; the increasing demand for petroleum and other raw materials by the ind has burgeoned from a small industry located mainly in the shallow areas of the Gulf of Mexico to a worldwide colossus moving into deeper water and more severe sea conditions. These developments have caused a revolution in the design of offshore drilling (离岸钻井) rigs/ships /units and the entire support fleet necessary for such a challenging undertaking. This includes crew boats, offshore supply boats, high powered towing vessels, pipe laying barges (海 底铺管驳船)/ships and countless other specialized craft. Furthelel existing operations, this may be a sound approach. Consequently, in such situations, basic design(基本设 计) may be limited to examination of minor modifications to dimensions powering, and arrangements.
At the other extreme, totally new seagoing missions, such as the ocean transportation of liquefied natural gas (LNG), when first introduced, caused the designer to begin with a blank piece of paper and proceed through rational design engineering with crude assumptions subject to frequent and painstaking revision and development.

丙辰中秋,欢饮达旦,大醉,作此篇,兼怀子由。 明月几时有?把酒问青天。不知天上宫阙,今夕是何年。我欲 乘风归去,又恐琼楼玉宇,高处不胜寒。起舞弄清影,何似在 人间? 转朱阁,低绮户,照无眠。不应有恨,何事长向别时圆?人有 悲欢离合,月有阴晴圆缺,此事古难全。但愿人长久,千里共 婵娟。
