Lingshui 172 is situated approximately 150 km offshore from Hainan Island, in water depths exceeding 1,500 meters. It is China’s first independently operated deepwater gas field, developed with a semisubmersible FPU linked to six subsea wells and connected via umbilicals and flowlines to an onshore terminal.
The project scope includes subsea trees, manifolds, dynamic risers, infield pipelines, and a gas export pipeline to shore. Advanced technologies and deepwater engineering were deployed to manage the technical challenges posed by the field’s environment and depth.
Provided Services
For this project, NWE is providing:
- Continuous third party inspections at fabrication yards for subsea structures, risers, and pipeline components.
- Coating, welding, and NDT inspection oversight at multiple facilities in China and Southeast Asia.
- Dimensional control and mechanical integrity checks during assembly of critical equipment.
- FAT and SAT witnessing for subsea and topside packages.
- Surveillance during loadout, transport, and offshore installation to verify handling, preservation, and compliance.
- Documentation review and certification support to ensure full traceability and regulatory adherence.
