Lingshui 172 – Pioneering China’s Deepwater Gas Frontier
Independent Development, Global Standards
Located in the South China Sea, Lingshui 172 marks China’s first independently developed deepwater gas field. With NWE providing continuous inspection and oversight across Asia and Europe, this project reflects the highest levels of offshore engineering, quality control, and execution precision.
NWE’s Role in Lingshui 172
Global Supervision for a National Milestone
NWE is trusted to support this strategic project through:
Third-party inspections at fabrication yards for subsea structures, risers, and pipelines
Oversight on coating, welding, and NDT inspections at multiple international sites
Dimensional control and mechanical checks during equipment assembly
Witnessing of FAT and SAT for both subsea and topside systems
Surveillance during loadout, transport, and offshore installation
Full documentation and certification support
Through operations across China, Singapore, Malaysia, Norway, UK, and India, NWE ensures compliance at every link in the supply chain.
China’s First Deepwater Development
A Technological Leap Beneath the South China Sea
The Lingshui 172 field is located 150 km offshore Hainan Island, in water depths exceeding 1,500 meters. Developed with a semisubmersible Floating Production Unit (FPU) and connected to six subsea wells, the field links through umbilicals and flowlines to an onshore terminal, enabling efficient gas export.
Technical Scope & Innovation
Advanced Subsea Engineering for Harsh Environments
Key components of the field’s infrastructure include:
Subsea trees, manifolds, infield pipelines, and risers
Dynamic export pipelines from the seabed to shore
High-spec equipment assembled and qualified across global locations
Facing high-pressure environments and deepwater constraints, the project leverages the latest in subsea and structural design technologies.
