Cooperation Background:

CNOOC focuses on offshore oil & gas exploration and production, operating offshore drilling platforms, subsea valves and underwater production trees. The equipment works in deep-sea high pressure, seawater corrosion and alternating temperature environments, demanding high-reliability subsea-grade sealing products. CNOOC cooperates with Guohao Seals for customized sealing OEM & ODM services.

1. Subsea equipment endures ultra-high seawater pressure, continuous saltwater immersion and gas medium corrosion;

2. Subsea replacement of seals is very difficult, zero-leakage performance is mandatory;

3. Strict material certification and pressure test requirements for subsea equipment accessories.

Guohao Seals Services (OEM + ODM):

1. OEM Production: Mass produce CNOOC specified subsea spring energized seals, valve seat seals and high-pressure O-rings;

2. ODM Customization: Develop special PTFE composite sealing structures for subsea valves and christmas trees, solving the failure problem caused by deep-sea high pressure and salt corrosion;

3. Rapid OEM Delivery: Complete high-pressure test and material certification together, support batch delivery for offshore construction windows.

Cooperation Achievement:

Cumulatively supplied more than 1.9 million sets of subsea sealing parts for multiple offshore development projects. The stable sealing performance reduces subsea leakage risks. Guohao Seals is a qualified sealing supporting vendor of CNOOC.
