MAIN MATERIALS AND QUANTITIES Port of Cabinda
this infrastructure will have an operating capacity well above the existing floating pontoon, especially in periods of strong undulation.
Mota-Engil Angola will not only offer the dredger at the end of the work, but will also promote, during the course of the work, the training of the Port’s technicians, which will be acquired continuously on site for 10 months.
Breakwater
The breakwater will be approximately 660 m long, extending from the beach towards the sea, to an area where
the sea bottom level is approximately -6.00 m (LAT). The breakwater
is defined by two distinct sections, the initial section, establishing the access path, arranged in the S-N direction, and the next section, on the sea side, deviated in approximately 50o to NE in relation
to the direction of the section of the access path.
The type of structure of the breakwater will be similar along both sections, composed of two metal sheet-pile curtains connected by an anchoring system composed of steel circular-section tie rods.
• Road access with a width of 12.25 m and a length of 295 m (1st phase).
Light pier with a depth of 5 m and
a berthing capacity for vessels up to 1,700 metric tons (passenger terminal);
• It will be necessary to build a floating dock compatible with the current project for this pier to allow the berthing of passenger ferryboats;
• Mole with a width of 40 m and a length of 365 m and roll-on/roll-off ramp with a width of 25 m, a length of 30 m and a slope of 10% (2nd phase). This is a 9 m
