Pier for repair and fitting of ships up to 250,000 DWT
Client: Officine Allestimento E Riparazione Navi E Cantieri Navali
Location: Port of Genoa, Italy
Construction Period: 1971 - 73
The pier on which two big cranes run is built on bearing elements featuring 10 large sized reinforced concrete cellular caissons, and rests on a subsiding muddy-sandy ground with also the presence of clays. It is located West of the old Molo Giano. The ground was reclaimed by replacing strongly muddy-sandy surface layers with a layer of sand and then preloaded by filling the caisson cells with sand. After the necessary time, the cells were emptied and then the superstructure and the deck connecting beams were built also using precast elements.
Pier for floating dock facilities at the port of Genoa
Client: Consorzio Autonomo Del Porto Di Genova
Location: Port of Genoa, Italy
Construction Period: 1980 - 82
The pier protecting and servicing the pre-stressed reinforced concrete floating dry dock in the Port of Genoa was fully built with reinforced concrete cellular caissons. The14 caissons, two of them used as anchoring piles of the dry dock, have a body of 21.64 x 17.30 m and are placed on a rubble foundation at varying depths from -17.50 to -20.00 metres. In order to absorb the energy of incident waves, the form wall is perforated as to internally unite the sea with a wave chamber into the caisson. For the top deck, prefab beams were used to connect the caissons. It was then completed on site with reinforced concrete cast. Two rails with a 14 m gauge run on the deck for two cranes one with 100 t lifting capacity at 60 m, and the second one with 40 t lifting capacity at 45 m. The overall length of the pier is approx. 380 metres.
Port of Voltri - Genoa: Eastern and Western Lee Breakwaters
Client: Consorzio Autonomo Del Porto Di Genova
Location: Port of Voltri, Italy
Construction Period: 1977 - 80 and 1984 - 1990
The Western lee breakwater protrudes into the sea for an overall length of 600 m. Its infrastructure features No. 20 reinforced concrete cellular caissons with 30.10 x 15.94 m body each. The caissons are placed at -18.00 m on a rubble layer transported and layed with barges. The caissons have been ballasted with dredged sand.
The root portion of the breawater is connected to the shore through a rubble mound slope to retain the embankment. This rubble mound is armoured by a cover layer made of 40 t concrete units.
The Eastern lee breakwater has a total length of 1,665 m and it was built in two sections. The first one stretching from the outer breakwater to the shore is 970.90 m long: its infrastructure consists of 32 precast reinforced concrete cellular caissons which lie on a rubble foundation at varying depth, from -13 to -16 m. Their body is 30.45 x 16.04 m in size. The superstructure has a rear wave wall (with respect to the front wall) on the seaside to reduce wave overtopping and reflection. The second section of the breakwater, which is 694 m long, is a transverse jetty with external protection wall consisting of tetrapods with a maximum weight of 40 t placed on a sea bed slope from -13 to -5.50 m depth.
Water Clarification Tank of the Water Treatment Plant in the Historic Centre of Genoa
Client: Società Carena S.p.A. (capogruppo)
Location: Genoa, Italy
Construction Period: 1984 - 1990
The water treatment plant for sewage water from the old city centre of Genoa serves a total population of 220,000 inhabitants. The four clarification tanks of the plant were built by placing No. 8 reinforced concrete cellular caissons with a 17.15 x 22.38 m size on a -7.00 m sea bottom. The caissons precast at the building yard in Ponte Canepa were then connected on site. A smaller (m 17.15 x 10.80) 9th caisson was built to contain the pump room.
