Abstract:

Subsea system, as one of the primary mode of oil field development, widely researched and applied by many countries in the world, has obvious economic advantages in deep sea or marginal oil and gas field development. The oil and gas follow in subsea manifold from XMAS tree and transport to subsea pipeline. The quality of subsea manifold will affect the oil field development safety and environment. Especially the research on the subsea manifold module project, the paper introduces the quality control about the subsea manifold piping system. References and advices are provided for oil gas field development inspection, especially in deepwater environment inspection.
