Since 2008, NANHAI developed and manufactured various buoyancy airbags for salvaging shipwrecks and laying underwater pipelines. And install the box culvert. In 2013, our buoyancy airbag technology extended to the field of offshore oil engineering, and became a qualified supplier and strategic partner of CNOOC (China National Offshore Oil Corporation) airbags and related products.

NANHAI buoyancy airbags can help our customers achieve incredible cost reductions. For example, our airbags produce 30 tons of net buoyancy per ton of rubber, while the use of steel buoyancy tanks produces 2 tons of net buoyancy. In addition, our airbags can be reused up to 50 times.

In 2021, NANHAI began to use buoyancy airbags to transport and install equipment for offshore wind power projects, which can replace large floating cranes, and on the basis of ensuring safety and reliability, greatly reducing the installation and transportation costs of offshore wind power projects, and gradually become offshore wind power mainstream choice for the project.
