Design of the Western Breakwater for the Outer Port at Punta Langosteira, A Coruña, Spain

ABSTRACT
This paper describes the design process and hydraulic stability tests corresponding to the western breakwater in the outer port at Punta Langosteira (A Coruña, Spain). This breakwater is the second phase of the 1.35 km-long secondary breakwater; the first phase was the single-layer Cubipod armored southern breakwater. The western breakwater is protected with a single-layer 25- and 30-tonne Cubipod armor in the trunk and a double-layer 45-tonne Cubipod armor in roundhead. The design was validated with small-scale 3D tests of the two alignments of trunk and the roundhead. 1,360 15- and 25-tonne Cubipod units are being re-used from the Southern and Northern breakwaters, completed in 2012 and 2013, respectively. 6,670 new 25-, 30-and 45-tonne Cubipods were manufactured using 25 vertical formworks and 87 bases, in a 24 hour/day work cycle and 3.5 units/day/formwork with a 6-hour demolding time; 1,100 m3/day of concrete was consumed and Cubipods were piled up to five levels. The construction of the western breakwater started in April 2015; armor is being completed before the winter season and a crown-wall is planned to be built during the summer of 2016.
