Sentence 2. Vocabulary summary 3. Exercise
１ general introduction
• There has been a notable attempt in new and modernized yards to achieve an assembly line type of flow of materials to assembly areas and an orderly flow of assemblies to the final building site. • 在新的现代化船厂中，很明显的尝试去完成 组装区流水线式的材料流以及有序的组件流， 到达最终的建造点．
• 2) in contrast to Arendal’s assembly system ,Ingalls’s Pascagoula yard,fatures sevaral parallel assmbly flow lines,each being at the fabrication shops and extending through the subassembly area to the module assmbly area. • 和Arendal的装配系统相反， Ingalls’s Pascagoula 船厂，设置了几条平行的生产 线，每条都由制造车间经过小组装区延伸至 大组装区．
3 steel storage 钢料存储
• In a typical modern shipyard there is a compact plate and shape storage area from which steel is fed,via an automatic roller conveyor system,through automatic blasting and paint priming facilities into a large enclosed fabrication shop where assmbly units over 200 tons can be constructed.
• 2)The ground level building site • 水平建造场地 • Unique methods of launching have been developed where the ship is transferred to a special floating facility and then undocked in the usual manner. • 发展了独特的下水方法，这里，船被移到 一个特殊的漂浮装置，然后用常用的办法 出坞．
• 1)The principal advantages of the basin over the sloping way are that the headroom limitation for cranes is minimized,the ship can be built without the inconvenience of declivity corrections,and the launching operation is eliminated. • 船台比滑道的主要优势在于：起重机的净空 高度限制被减少，避免斜度矫正的不便，同 时下水工作量也减小．
• 在典型的现代化船厂中，有紧凑的钢板和 型材存储区，钢料从中取出，通过一滚动 传动系统，经过喷丸除锈，涂底漆装置， 到达能生产２００吨重组装结构的室内装 配车间．
4 steel fabrication and assembly • 1)The completed portion of the
ship is systematically moved out of the covered area and into the building basin as new sections are added. • 船被完成的部分系统性地移出棚装区，送至 船台，在那里加上新的组件．
• Due primarily to the unpredictability of the market,it is difficult to achieve a balance between introducing expensive assembly line equipment to suit one type of ship and ,at the same time,maintaining the yard’s capacity to construct different types of ships and other marine structures. • 主要因为市场的不可预测性，在引进昂贵生 产线来适应一种船的生产，同时又保持船厂 建造多种船和海洋结构物的能力之间难以达 到平衡．
5 matrials handling
• Movement of heavy units,some of more than 200 tons,from a panel line or painting facility is usually accomplished using a self-propelled trailer type transporter employing a hydraulic mechanism within the vehicle. • 一些重超过２００吨的重单元从板间或涂装 间完成移动，通常用自带动力的推车，该车 内装液压机械．
6 shipyard facilities
• A shipyard generally contains several specific facilities laid out to faciliate the flow of material and assemblies. • 一个船厂一般包含几个特别的设备布置， 以便材料流动以及组件的运送．
