Abstract: Subsea manifold is the core facility for subsea oil and gas fields development， is capable of gothering， tegulating， and ensurity underwater oil and gas production. It can be designed with different struture and function according the specific requirement of the oil and gas field. Base on the subsea manifold engineering experience in the South China Sea deepwater oil field， performing foundation type， key technology， manifold function module type and new technology application are analysised and researched. This study offers reference and experience for domestic subsea manifold technology and key equipment development.

Key words: subsea manifold, suction pile, compact manifold, suction pump, manifold application
