NEW PORT OF PATRAS
CONSTRUCTION COST: US$ 7.5 M.
CLIENT: MINISTRY OF TOWN PLANNING, ENVIRONMENT AND PUBLIC WORKS OF GREECE
The project involved the construction of four berths for Ro-Ro and passenger ferryboats up to 200 m. in length. Due to the complex and adverse geotechnical conditions of the sea floor (very soft silty clays) special techniques were adopted (e.g. plastic drain strips, stone piles, preloading) in order to accelerate settlement by inducing the clayey bottom pore pressure dissipation and thus improving altogether its bearing capacity.
The quay walls will be constructed with reinforced concrete cellular caissons, which will be formed either in dry docks or on specially designed platforms and then floated, transported by tug boats and launched in place by controlled flooding of the caisson's cells. The quay walls and port basin are protected by a 1500 m long breakwater, founded in depths of -30 to -40 m in the form of a longitudinal island running parallel to the berths. Special techniques were also used in the case of the breakwater, incorporating plastic drains, woven geotextiles and staged construction. TRITON was involved (in association with A.D.K. Engineers) not only in the design and tendering phases of the project but also in the Project Management and supervision of construction.
