NANHAI Floating Technology Application

Offshore Oil and Gas Buoyancy Field

The rapid pace of offshore oil and gas exploration and development worldwide has made the oceans a strategic area for global energy resources. NANHAI technology research team has developed solutions for precise docking of underwater pipelines with offshore platforms, using pneumatic floats to reduce operational complexity and costs. This advancement is crucial for enhancing China's energy security and achieving carbon neutrality goals.

Advantages of NANHAI floating platforms
Reduced construction difficulty
No longer dependent on super large equipment, not limited by the difficulty of water operations, reducing construction difficulty and expanding construction methods
Ensuring construction safety
Due to the controllable volume of the floating platform, overall balance adjustments can be made by adjusting the pressure of the platform during buoyancy assistance
Save construction costs
By providing buoyancy, reducing or even eliminating the use of floating cranes, saving construction costs
