流花11-1导管架是目前亚洲最深的深水导管架。与浅水导管架相比，流花11-1导管架存在着设计风险高、建造周期长、钢材生产工艺高、焊接困难等特点。本文综合分析了流花11-1导管架的风险管理，从设计风险到建造周期影响，从钢材焊接工艺到具体施焊，全面分析和评估了主要风险并采取了有效的风险控制措施，成功运用项目风险管理经验，保证了项目的质量、成本和进度，也为以后同类深水导管架项目管控提供了指导和参考。

n Branch, CNOOC， Shenzhen 257237， Guangzhou China) Abstract Liuhua 11-1 jacket is the deepest deepwater jacket in Asia at present. Compared with shallow water jacket， Liuhua 11-1 jacket has the characteristics of high design risk， long construction cycle， high steel production technology and difficulty in welding. This paper will study the production process of S420 super-strength steel， jacket design risk， construction risk， dynamic performance， welding quality control measures and other aspects， so as to provide reference for similar deepwater jacket project management and control in the future.
