5 Key Advantages of Bonna RCCP for Offshore Project

1. Large Diameter 

Manufactured up to 4,000 mm in diameter for high flow capacity

2. Durability

Durable and reliable, ensuring a lifetime of dependable service

3. Simplified Construction

Easy to connect underwater and required less civil works

4. Low head loss
Smooth, with low head loss characteristics for low-cost performance

5. Custom-made solution
Custom-designed for the project needs and configuration

1. Large Diameter

  • Bonna Pipe RCCP is manufactured up to 4,000 mm in diameter
  • Water pipelines and industrial plants use and circulate large quantities of water that needs large-diameter pipe
  • Large diameters deliver cooling water with desirable velocities, lower friction losses, and therefore lower pumping costs

2. Durability

  • The RCCP pipeline withstands full vacuum conditions
  • The protection of steel by concrete is permanent, therefore no need for maintenance
  • The external reinforced concrete compressive allows for jacking or microtunneling method
  • Bonna pipe concrete inner wall does not require any specific protection against abrasion thanks to its high strength & compactness

3. Simplified Construction

  • Bonna Pipe RCCP is jacked in one single operation thanks to the steel cylinder embedded in reinforced concrete pipe (no need for casing)
  • Bonna Pipe RCCP can be designed for jacking installation in curve
  • Bonna Intermediate Jacking Station allows to reduce number of pits
  • Comprehensive design review and preliminary plan & drawing integrate technical discussion to comply with conditions at construction site

4. Low Head Loss

  • Roughness Coefficient “k”=0.0001m  corresponds to the internal lining of the Bonna pipelines RCCP
  • The manufacturing and installation processes for Bonna Pipe RCCP result in pipelines with smooth surfaces across the joints between adjoining pipe units
  • The concrete or mortar lining does not deteriorate with age when flowing full

5. Total Custom-made Solution
