摘 要：进行设备基座设计绘图的关键是要进行信息的收集，首先要观看与船东签订的建造技术规格书中基座要求，其次要了解船级社规范中对材料的材质等级要求，还要选取相关的最新结构、铁舾图纸，用做背景，最新的设备VCD用做参照，最后完成最新的设备布置图。

每一张基座设计图纸的完成都需要经过一系列的工作包括：确定设计方案、建模型校核、设计方案细节确认、完整性检查。基座布置图的成图都要走流程交给相关的主管和主任，通过严格的审查之后才能出图。在设计设备基座的时候不仅要考虑到重量，造价，制造，外型这些方面，更重要的是要考虑到设计出的基座是否符合船东的要求、是否存在干涉、布置的位置是否合理、是否方便施工等种种问题。

   基座设计完成之后，要对基座做强度校核，确保基座的力学性能，保证在极限工作状态下也能安全的使用。

本文对NG2500X自升自航海洋服务平台的应急发电机基座做了一个简要的设计，在参照CCS规范，同时学习了相关的软件之后进行了有限元分析。

Abstract：The key to design and draw the equipment foundation is to collect the information. First, it needs to see the base requirements of the construction technical specifications, which is signed with the ship-owners. Next, we need to understand the levels of materials, which are required by construction technical. And then, we should choose the latest structures and outfitting drawings to be used for the background and the latest VCD to be used for the reference. At last, we can finish the newest equipment layout.

The completion of each base design drawings needs a series of work, including determining the design, model checking, design details confirmed, integrity checking. According to the process, the whole base layout also needs to give the relevant supervisors and directors. After strict examination, the figure can be completed. In the design of the requirement base, we should not only consider about the weight, cost, design and out looking, but also think more about problems such as whether the base design fits the ship owner’s requirements, whether the interference exists, whether the position of layout is reasonable, whether it is convenient for construction, and so on.

After completing the base design, we should check the strength of the base to ensure the mechanical properties of the base, and make sure that it can be used safety in the extreme working condition.

Referring to CCS norms, this thesis makes a simple design to the emergency generator base of NG2500X Self-propelled Jack-up Marine Service Platform, and implements the associated finite element analysis after learning the relevant software.
