设计变更管理是海外油田建设项目合同管理的核心内容,涉及项目管理的各个方面。由于详细设计技术复杂、周期长、对其他建设阶段的影响重大,工作涉及多个界面,因此需要科学严谨的设计变更管理程序。基于伊拉克艾哈代布油田详细设计变更管理实践,总结了详细设计变更的范围和成因;变更依据的类别和确认方式;变更建议书的内容和作用。通过分析变更管理程序中存在的问题,提出了有效实用的详细设计变更管理程序,明确了变更的指令来源、变更建议书的内容、变更启动的时机、设计分包的变更管理等关键环节,对后续项目执行提供了经验,对提高海外油田建设项目合同管理水平具有积极意义。
Design change management is the core content of contract management of overseas oilfield construction projects and involves all aspects of project management. Because detailed design techniques are complex, long-lived, impacting other phases of construction significantly and involve multiple interfaces, a rigorous scientific design change management process is required. Based on the detailed design change management practices in Iraqi Ahdabu Oilfield, the scope and causes of the detailed design changes were summarized; the basis and types of changes were confirmed; and the content and role of the proposals were changed. By analyzing the existing problems in the change management procedure, the paper presents an effective and practical detailed design change management procedure, clarifying the source of the change instruction, changing the content of the proposal, changing the timing of starting, and the change management of the design subcontract. Follow-up project implementation provides experience, to improve the overseas oilfield construction project contract management level has a positive meaning.
