- 摘要:
陵水17-2气田深水半潜式平台是全世界首座十万吨级深水半潜式生产储油平台。针对陵水17-2气田深水半潜式平台天然气压力高、气量大、凝析油闪点低、重量控制严格等特点,提出一系列适用于深水半潜式生产储油平台的安全保障措施,包括采用水下隔离阀(Subsea Isolation Valve,SSIV)、高完整性压力保护系统(High-Integrity Pressure Protection System,HIPPS)、凝析油舱惰性气体覆盖系统创新设计等,并从设置必要性、设置位置及特殊设计等方面展开详细论证,保障深水半潜式生产储油平台的安全运行,对后续大型深水气田开发具有借鉴作用。
The Lingshui 17-2 deepwater gas field semi-submersible platform is the worlds first 100 000-ton class deepwater semi-submersible production and storage platform. In view of its characteristics such as high natural gas pressure, large gas flow rate, low flash point of condensate and strict weight control, a series of safeguarding measures applicable to the deepwater semi-submersible production and storage platform are proposed. These innovative design features include the application of SSIV(subsea isolation valve), HIPPS(high-integrity pressure protection system), and condensate tank inert gas blanketing system. Detailed discussions and verifications on aspects such as the necessity of safeguarding systems, their locations and special design features are also carried out to ensure the safe operation of the deepwater semi-submersible production and storage platform, which provides valuable reference for the development of large deepwater gas fields in the future.
