The tunnels executed by means of microtunneling offer several essential applications in marine fish farms and continental:
Water catchment from deep and temperature stable areas, guaranteeing a continuous and quality flow without pipelines exposed to waves.
Return outfalls that conduct the treated effluent offshore and disperse it with diffusers, complying with environmental regulations and avoiding recirculation to the intake.
Subway crossings under beaches, roads or other infrastructures to link onshore facilities to the sea without trenching or interfering with traffic or tourism.
Protection of pipelines and reduction of maintenanceThe pipelines, being buried, are safe from storms, biofouling and vandalism, prolonging their useful life and reducing production stoppages.
Ancillary services accommodation (sensors, fiber optics, air lines for cleaning) inside the same tunnel, simplifying the operation and control of the farm.
The use of closed shield tunnel boring machines allows the pipe (GRP, concrete or steel) to be laid with millimetric precision, minimizing the environmental footprint and shortening construction times.
