The expansion of the Naos dock in the Port of Arrecife (Lanzarote) will substantially improve the quality of service in the port, since it will allow to dock ships even in the conditions of winds and SSW waves, which are currently causing operational problems. The spring is projected as a solution of length 149.70 ml and a superstructure width of 13.00 and a Ro-Ro ramp of 37.00x30.50 m with access through the Contradique de Naos.
