【摘要】：石油化工项目相对于市政工程、建筑工程等其他类建设项目,有其特殊性,其装置之间是承接关系,牵一发而动全身,且其投资巨大、建设周期长、工艺技术复杂、设备特殊、介质腐蚀性强、高温高压、易燃易爆,风险很大,所以石化项目对建设过程要求严格。影响石化项目建设成败的原因有很多,其中工程设计管理(包括质量、进度综合控制、费控、沟通、风险等管理)是相当关键的因素,研究石化项目设计管理,对项目整体能否顺利建成投产,有重要意义。目前,国内外大型石油化工项目流行设计、采购、施工一体化EPC总承包工程建设模式,在缩短建设周期、降低项目成本、减少建设中间环节等方面具有显著的优势,国内石化行业项目建设领域也越来越多的采用这种模式。在EPC总承包管理模式的应用过程中,设计管理处于整个项目的核心地位。本文通过对某石化EPC总承包项目的设计基本要求、设计要点及设计管理目标出发,发现国内石化EPC设计管理过程主要是依靠ISO9000质量管理体系、QHSE(Quality、Health、Safety、Environment)管理体系、公司内部的作业文件以及国际上EPC通用的设计管理流程,但设计管理程序不清晰,反映在没有抓住国内石化的建设特点,把质量、进度、费控、沟通、风险等设计管理的影响因素切实的剖析出来,这将影响到石化EPC项目执行过程中采购、施工、试车等控制节点能否准确而正常进行。找出该项目设计管理中存在的问题,分析和解决这些问题,从而得出设计管理各因素对项目影响程度强弱顺序为质量、进度、费用、策划、沟通、风险、文控的管理。完善设计全过程管理机制,并将设计管理注入采购、施工等环节中,项目质量得到保证。通过Hazop分析(危险与可操作性分析)进行图纸安全性及可操作性审查,修改设计385项;通过P6进度计划软件及专业协作表时间点控制等手段,设计进度节点得到控制,设计采购文件准时交付采购部,11400张(折合A1图幅)施工图按进度计划工期完成;主体设备及散装材料、工艺管道材料等费用均有所降低,主体设备节约成本441.89万元,工艺管道通过满足需要质量设计的原则,降低成本120.40万元;通过风险转移和提前评估控制了风险的产生,设计管理形成了程序模式,充分发挥设计管理在石化EPC项目中的核心地位,并取得2014年集团公司设计样板工程。本文对于提高国内石化EPC项目设计管理能力都有一定的帮助,同时也可以作为设计经理在执行石化EPC项目的管理参考。
[Abstract]:Compared with other kinds of construction projects, such as municipal projects, construction projects and so on, petrochemical projects have their own particularities. Their units are connected with each other, and their investment is huge, the construction period is long, the process and technology are complex, and the equipment is special. The medium is corrosive, high temperature and high pressure, flammable and explosive, and the risk is very high, so the petrochemical project requires strict construction process. There are many reasons that affect the success or failure of the petrochemical project construction, among which the engineering design management (including quality, progress comprehensive control), Cost control, communication and risk management are quite key factors. Studying petrochemical project design and management is of great significance to whether the whole project can be successfully completed and put into operation. At present, domestic and foreign large-scale petrochemical projects are popular in design and procurement. Construction integration EPC general contracting project construction mode has remarkable advantages in shortening construction cycle, reducing project cost and reducing intermediate link of construction, etc. The domestic petrochemical industry project construction field also more and more uses this pattern. In the EPC general contract management pattern application process, Design management is at the core of the whole project. This paper starts with the basic design requirements, design essentials and design management objectives of a petrochemical EPC general contracting project. It is found that the process of EPC design management in domestic petrochemical industry mainly depends on the ISO9000 quality Management system (QHSE), the internal working documents of the company and the international EPC design management process, but the design management procedure is not clear. This is reflected in the failure to grasp the characteristics of domestic petrochemical construction, and to analyze the factors affecting design management such as quality, progress, cost control, communication, risk, etc., which will affect the procurement and construction of petrochemical EPC projects. This paper finds out the problems existing in the design management of the project, analyzes and solves these problems, and concludes that the order of influencing degree of design management on the project is quality, schedule, cost, etc. Planning, communication, risk, document control management. Improve the design process management mechanism, and design management into the procurement, construction and other links, The quality of the project is guaranteed. Through Hazop analysis (hazard and maneuverability analysis), drawing safety and maneuverability are reviewed, and 385 items of design are modified, and P6 schedule software and professional collaboration table are used to control the time and point of time, and so on. The design progress node is controlled, the design procurement documents are delivered to the purchasing department on time, 11400 construction drawings are completed according to the schedule, and the cost of the main equipment and bulk materials, process piping materials, etc., are reduced, The main equipment saves four million four hundred and eighteen thousand and nine hundred yuan in cost, the process pipeline reduces the cost one million two hundred and four thousand yuan by satisfying the principle of quality design, the risk generation is controlled by risk transfer and early evaluation, and the design management forms the program mode. Give full play to the core position of design management in petrochemical EPC project, and obtain the design model project of 2014 group company. This paper is helpful to improve the design management ability of domestic petrochemical EPC project. At the same time, it can also be used as the management reference of the design manager in the execution of petrochemical EPC project.
