Turbot fish farm in Camariñas

Camariñas Submarine Outfall

The subsea outfall project in Camariñas, Galicia, Spain, represents an advanced solution to improve the infrastructure of a local fish farm. Located in an environment of great ecological value, this project demonstrates how modern engineering can address the most complex geological challenges while minimizing environmental impact.

With precise execution and advanced technology, the subsea outfall not only optimizes fish farm operations, but also ensures the sustainability of marine resources in the region.

General project details

Location: Camariñas, Galicia, Spain.
Tunnel length: 150 meters.
Project durationPerformed in complex geological conditions.
Main objectiveTo improve the operational efficiency of the fish farm and preserve the marine environment.

This project not only solves an essential technical need for the fish farm, but also sets a benchmark in the use of advanced technologies for challenging marine environments.

Technical specifications

Inside diameter: 2,500 mm.
Excavated landVery hard and abrasive granite.
Method used: Hydraulic shield tunnel boring machine (Hydroshield).

The use of a Hydroshield TBM was key to ensuring drilling accuracy, allowing excavation in extreme conditions without compromising safety or the marine environment.

Logistics and technical challenges

The execution of the tunnel in Camariñas presented several challenges due to the geological characteristics of the terrain and the proximity to the marine environment. Thanks to advanced technology and meticulous planning, the project successfully overcame these challenges.

Project highlights:

Excavation accuracyThe geological conditions required a thorough control of the drilling trajectory.
Process safetyHydroshield TBM: The Hydroshield TBM successfully handled the abrasive terrain, minimizing operational risks.
Reduced environmental impactThe execution of the project was guaranteed to be respectful of the marine environment, protecting the local ecosystem.

Environmental and social impact

The Camariñas submarine outfall has contributed significantly to improving the fish farm's operations, ensuring a controlled and environmentally friendly discharge. Notable benefits include:

Marine conservationCareful construction of the tunnel minimized the impact on the coastal ecosystem.
Operational efficiencyThe improvement in infrastructure has optimized the operation of the fish farm, increasing its sustainability.
Reference modelThis project is an example of how to integrate high-tech solutions into sensitive natural environments.
