Ultra-Deepwater HPHT Subsea Wellhead System 超深水高温高压水下井口系统

China's First PSL 4S Grade国内首套 PSL 4S 级别

The first domestically developed subsea wellhead system at API 17D PSL 4S — the highest product specification level — filling a critical technology gap for China's ultra-deepwater oil and gas development.国内首套自主研发的 API 17D PSL 4S 级别水下井口系统，PSL 4S 是 API 17D 标准下最高产品规格，填补国内超深水油气开发关键技术空白。

BV + CCS Dual CertificationBV + CCS 双船级社认证

Certified by both Bureau Veritas (France) and China Classification Society (CCS), the FE-15 system meets the most rigorous third-party verification for offshore deepwater equipment.通过法国船级社 BV 与中国船级社 CCS 双重认证，FE-15 系统满足海上深水装备最严格的第三方验证标准。

Coupled Dynamics Modelling耦合动力学建模

Developed in partnership with Professor Xu Liangbin's research team at Sun Yat-sen University — the "Platform–Riser–Wellhead" coupled dynamics model underpins the structural design validation for ultra-deepwater applications.联合中山大学许亮斌教授团队研发"平台-隔水管-井口"耦合动力学建模，为超深水应用的结构设计验证提供理论支撑。
