Posco sea water intake

Angamos power station
Basic and Detail Engineering
Cobra Central Térmica Mejillones S.A. requested PRDW the services of engineering for the development of the project type EPC of capture and water unload of sea for the Angamos Power Station.
Chile, Antofagasta, Bay of Mejillones
2009

The project involved the design of sea water syphon located at a depth of-8.0m NRS through a pipeline of approx. 0.9m in diameter to 5.200m³/h and design of the outfall discharge of approx. 0.93m in diameter to 3.500m³/h with their respective diffusers located at the altitude -8m NRS.

The project also considered the structural design of pier pipe support and suction towers.

The project considered the following analysis and studies:

  • Hydrodynamic analysis to determine loads on the pipe.
  • Design of the ballast for stability of the pipe.
  • Design of water intake tower.
  • Verification of the hydraulic analysis of pipeline and heights in the uptake and discharge bilge.
  • Study of variation of beach profile to define stretch buried.
  • Analysis of charges for the launch and assembly.
  • Diffuser design discharge and diameter of the outfall.
  • Structural design of coastal structures.
