The technology of OKet Vap-O-Loc® fully composite floating roof originates from Dynaglass, a company based in Singapore.

The Vap-O-Loc® fully composite floating roof possesses the following technological features:


Advantage 1: Integrated Unitization


Strong Reliability with Full Composite Material Integration:

1. Relies on the unique heat-curing molding technology of composite materials to ensure reliable connections between modules, as well as between the honeycomb material and the upper and lower plates.

2. Solves the potential risks of loosening and failure at joints that may occur with assembled floating roofs.

3. Reduces emissions of VOCs at the source by eliminating gaps at joints.

4. In case of leakage at any single point on the floating roof, the liquid ingress will be confined within the honeycomb unit, ensuring high safety.


Advantage 2: Corrosion Resistance


Corrosion Resistance:

The floating roof is made of full composite materials, which will not oxidize like metal, solving the problem of metal floating roof being prone to corrosion, while ensuring that the liquid chemical products in the storage tank are kept away from rust and other pollutants.

Excellent Media Compatibility:

1. It can meet the storage requirements of the vast majority of liquid chemical products.

2. For special applications, the composite material formula can be adjusted accordingly.


Advantage 3: Lightweight and High Strength


High Buoyancy:Additional buoyancy load can reach 36kg/m2.

High Strength:Capable of withstanding a concentrated load of 917kN/0.1m2.

Low Profile:The conventional plate thickness is only 80~100mm, which increases tank utilization while reducing tank volume occupancy.

High Safety Factor:Even with 12.5% of floating roof support failure, the deformation of the floating roof is only 7% under permissible conditions, with a safety factor exceeding 14.

Maintenance-Free for a Lifetime.

The service life exceeds 20 years.


Advantage 4: Intrinsic Safety


Utilizing vacuum injection technology ensures the floating roof sealability and consistency:

OKet creatively adopts vacuum injection technology to produce modules constituting the floating roof, ensuring long-term sealability and consistency of the floating roof modules.

Comprehensive airtightness testing ensures the overall structural stability of the floating roof:

By utilizing unique structural patents to test the airtightness of floating roof joints, in conjunction with airtightness testing of the annular seal, a closed-loop overall airtightness test is formed to ensure the reliable sealing of the floating roof's overall structure.

Adoption of full plate drag reduction technology to ensure electrostatic safety of the floating plate:

1. OKet adopts a unique full plate drag reduction technology, ensuring the overall resistivity of the floating roof between 106~109Ω·m through additives such as graphene.

2. Surface wear and local damage to the floating roof do not affect electrostatic dissipation.


Advantage 5: Fire Resistance and Explosion Resistance


Fireproofing and Flame Resistance:

The floating roof has a fire resistance time of over 2 hours.

Overall Explosion Resistance:

1. Through comprehensive simulation experiments and computational simulations, it has been proven that the floating roof can withstand transient pressures exceeding 1.5MPa during flash explosions, ensuring safety and reliability.



Advantage 6: Convenient Installation


Flexible and convenient installation methods:

1. Factory Prefabrication:

90% of the construction work for the floating roof can be prefabricated in the factory. This approach ensures faster overall construction time and more stable quality control.

2. Retrofitting Old Tanks:

It can also be adapted to small module construction methods with access through manholes. This avoids cutting the tank body and offers a safer and more convenient solution for retrofitting old tanks.

3. Shorter construction period, higher efficiency, and lower costs.

       4. No hot work, no electricity involved, ensuring safety.
