The company AECOM advises TE Subcom for the installation of the submarine fiber-optic cable of 6,600 kilometers in length, called 'Marea', which will communicate Spain and the United States from 2017, arriving at the Biscayan beach of Sopelana near the Port of Bilbao. The fiber optic cable will be buried in the sand of the beach, so the company AECOM requested the services of IHCantabria to elaborate this study.

The ultimate objective of this study is to establish the minimum burial depth of the cable so that it will not be unearthed in any case during its useful life and to estimate the operation of the cable based on the planned burial process. To determine the variability of the height of the beach and the seabed along the route of the Marea cable in the active profile of the beach, from its beginning on the dry beach to at least 200 meters from the line From coast to sea, including the effects of climate change.

Fifteen people will participate in this initial phase of the work, among engineers, divers, beach workers, operators and security guard. The laying will be 'born' of an existing underground pit or BMH, which in the past housed a coaxial cable (used to transport high frequency electrical signals) currently out of service. It is a concrete chamber above the water level at high tide. Laying will run up to three meters below ground in 'cast iron half' rods, resistant to abrasion and will be used as a protection. The specification pays particular attention to the environmental impact of the project, so that any impact is remedied.
