EMITE units, due to their shape and studied design, are very useful elements for the anchoring, installation and protection of submarine drainpipes on sandy bottoms. Thanks to their special shape and water dynamics on the sea bottom, they will settle quickly by burying themselves into the sand which is a real advantage compared with the technical status of other kinds of units or blocks developed for the same purpose.

This system of prefabricated units completely covers the drainpipe, leaving, however, great freedom of movement to the flexible pipe, without transmitting damaging mechanical forces.

EMITE blocks allow the protection of submarine emissaries or drainpipes on sandy bottoms by nailing themselves more and more into the sea ground, as time goes by, and therefore increase the emissary’s stability in case of storms and significantly reduce its environmental impact.

The EMITE unit could be described as a rigid and flexible block at the same time. It is rigid since it fully protects the drainpipe, avoiding a possible breaking as a consequence of exterior factors. It is flexible, though, because it adapts itself, in a certain way, to the bathymetry of the bottom, as it would happen in the case of a non-protected drainpipe. This flexibility, which allows the protected pipe to adapt itself to the changes of the sandy ground, avoids the breaking of the protection in zones where it is not supported by the bottom.

With the results obtained in the tests EMITE units can be dimensioned according to the characteristics of the studied zone, such as depth, significant wave height, peak period, as well as the canting angle of the EMITE units alignment with respect to the to the incident wave.

Further, the EMITE unit’s design allows the future incorporation of a new drainpipe next to the already installed one, reducing the time of achievement of those works and their cost.
