Subsequently, a metal insert is passed through said tube that is secured to the buoy, giving it mechanical resistance for anchoring cage-type rafts in aquaculture or the like.
  • Mooring buoys such as those described above are subjected to great efforts since their function is to resist the tension forces generated by the anchoring lines that connect the buoy to the seabed and the buoy itself to the maritime structure, acting as a shock absorber of the structure against the movements of the sea. For this reason, its structure must be strong enough.
