NANHAI Floating Technology Application

Offshore Wind Power Buoyancy Field

Currently, 70% of the world's potential sea breeze resources are located in deepwater waters with water depths greater than 50 meters. In near-shallow seas, wind turbines are inserted deeply into the seabed through steel pipes or jackets to fix the wind turbines.

Currently, the advanced floating platform technology in NANHAI can assist in the transportation and installation of offshore wind power project equipment, significantly reducing the costs of offshore wind power projects, gradually becoming the mainstream choice for offshore wind power projects.

Advanced Floating Body Project Of NANHAI

Offshore wind power jacket foundation steel pipe pile construction project

NANHAI's advanced floating structure technology assisted the successful completion of the jacket foundation steel pipe pile construction of the CGN Huizhou Port No. 2 offshore wind power project undertaken by the Xiamen Branch of CCCC Third Harbor Engineering Co., Ltd.

The NANHAI technical team worked hard to break through technical difficulties and provided buoyancy by tying the NANHAI pneumatic type floating structure to the jacket. A single pneumatic type floating structure can provide 140 tons of buoyancy, reducing the hoisting force of the floating crane ship and reducing the requirements for the hook head force required for hoisting. It greatly reduces the installation and transportation costs of offshore wind power project jackets, and has gradually become the first choice for offshore wind power projects.

  • The dimensions of the designed and produced pneumatic floating body are 3.2*20.5 meters.
  • A single pneumatic floating body can provide a buoyancy of 140 tons.
