Sea water intake and outfall LNG Quintero

The project involved the design of sea water intake located at -14m NRS through a pipeline of approx. 1.8m in diameter and a sea water outfall and their respective diffusers located at -12m NRS.

The project considered the following analysis and studies:

  • Hydrodynamic analysis to determine loads on the pipe
  • Ballast design for pipe stability
  • Determination of pipe diameter
  • Design of water intake tower
  • Pipeline hydraulic analysis verification and intake and outfall system heights
  • Beach variation study to define buried pipeline section
  • Loading analysis for launch and assembly
  • Loading analysis for temporary sheet piling considered during construction
  • Diffuser and outfall diameter design
  • Chlorination pipe design and installation
