Light Pneumatic Type Floating Structure

In the field of marine engineering construction and ship salvage, utilizing the volume of discharged water to obtain buoyancy is crucial. In order to achieve greater buoyancy support, the Light Pneumatic Type Floating Structure independently developed and produced by NANHAI Corporation are gradually being applied. Compared to using steel float drums, the advantage lies in obtaining significant buoyancy support with relatively low economic investment, enabling tasks such as underwater installation of steel components and ship salvage.

The Light Pneumatic Type Floating developed and produced by NANHAI Company mainly includes: lightweight flotation unit, installation net sleeves and slings, connectors and valves, etc.

The floating unit can be customized according to various buoyancy engineering projects to provide different buoyancy forces. Its excellent performance is very suitable for short- and medium-term flotation assistance projects.

Currently, the Light Pneumatic Type Floating Structure modules are mostly used in smaller engineering projects, such as laying underwater pipelines in shallow water areas.

Lightweight Pneumatic Floating Unit

  • Combining the outer rubber, skeleton, and inner layers enhances the floating body's wear resistance, pressure capacity, and gas sealing to prevent leaks.
  • The air valve facilitates inflation and deflation, as well as the installation of a traction frame for coordination.
  • The conical compression sleeve tightens the bladder, enhancing the air valve's bonding strength.
  • The quick-release buckle on the traction frame allows connecting ropes for dragging the entire float.
  • Using the inflation and deflation elbow tube to connect the air valve extends the air tube, making it easy to operate underwater.
  • Using the air valve to connect the inflation and deflation elbow tube acts as an outlet valve, making external valve access convenient, and enhancing practicality for inflation and deflation operations.

Supporting Equipment

The net sleeve structure can be securely tied to floats of any diameter, enabling multi-point lateral support bundling when the float is placed horizontally and single-point axial force when placed vertically. This innovative design is particularly suitable for large-diameter floats used in heavy-duty buoyancy applications, providing easy installation, removal, and transportation. It solves the issue of inability to perform underwater buoyancy bundling for large-diameter floats.

  • The net sleeve structure ensures safe operation in tilted buoyancy postures, surpassing traditional rope winding methods.
  • The net sleeve supports float buoyancy in water, ensuring high construction safety by protecting the float's body.
  • The net sleeve structure offers a simple, cost-effective bundling method with better stress conditions compared to bundling large steel floating drums, leading to significant cost savings and economic benefits.
  • Versatile and reusable, the net sleeve structure lowers procurement costs, reduces construction time, and enhances the economic benefits of projects.
