2 Soil condition encountered
In the offshore part of the routes, the seabed is comprised of clay with minor areas of sand.
From there, going towards the shore, there are sediments comprising mainly of sand (covered with sea-grass) with some clay.
In the nearshore area, the seabed is characterized by the presence of soft shelly clay with scattered outcrops of firm to stiff silty clay and CLAYSTONE rock (the light ORANGE colour in the map below);
In the inshore and shore line area, ridges of young LIMESTONE rock emerge. (the RED colour in the map below) and CLAYSTONE (the dark ORANGE colour in the same map);
Geological Map of the area:

A first campaign of Point Load Strength laboratory tests performed on the limestone rock samples revealed a rock hardness ranging from 17 to 50 Mpa (UCS value).

The following campaign in limestone rock, shows the data from samples analyzed in a
Geotechnical Laboratory in Italy, revealing increased UCS values up to 71 Mpa.
