EXECUTION METHODOLOGY FOR THE 1ST PHASE:
1. HZM combined wall driving (currently PK 235) – 100%;
2. Digging of the inside of the breakwater (currently PK235) – 100%
3. Placement of tie rods (currently PK235) – 100%
4. Embankment with sand from the beach to level +3.50 (currently PK235) – 100%
5. Vibro-compaction of the embankment at level +3.50 – (currently PK235) – 100%
EXECUTION METHODOLOGY FOR THE 2ND PHASE:
Given that it is presently impossible to have a dredger
for the supply of sand and
the creation of the following embankment platforms, in order to proceed with the execution
of the sheet piling in the 360 m of pier (width of 40 m).
Estimated dredging volume required for the 2nd phase (phase 2 and 3 in the following drawings) = 150,000 m3.
At the end of July, the driving of piles planned for the first phase was completed.

depth pier with berthing capacity for vessels up to 15,000 metric tons (cargo terminal);
The access path section will be 295 m long and 12.25 m wide. The length of the section on the sea side will be 365 m and its width will be 39.80 m.
The inner containment curtain of the breakwater will be used as a docking structure along two piers with different depths. The soffit of the initial section
of the breakwater will be used as a pier with an operating level of -5.00 m (LAT) and a length of 180 m. The main pier will be located on the soffit section of the side facing the sea. This pier will have an operating bottom level of -9.00 m (LAT) and a length of 340 m.
In the soffit of the breakwater,
in the area of inflection, in the transition between the two sections of the breakwater, a roll-on/roll-off (Ro-Ro) ramp will be built.
The ramp will be 25 m wide and 30 m long, and it will have a 10% slope.
