VINCI Construction offers a wide variety of expertise in marine and port works. 

For example, DEME, a specialised Group subsidiary, carries out many dredging and marine projects on all the continents. The main projects included the Gladstone port extension works in Australia and dredging and hydraulic works to prepare the creation of two artificial islands off the coast of Abu Dhabi in the United Arab Emirates. The company is also working on the seventh and last offshore wind farm in the North Sea off Belgium (the Northwind project), for which DEME's specialised subsidiary GeoSea is building the foundations and installing 73 steel mono piles. The last order follows on from the C-Power project, a 54-turbine offshore wind farm for which construction got under way in 2008 and will be completed in 2013.

In France, the VINCI Construction France subsidiaries specialising in marine and inland waterway works continued work on many projects and booked orders for new ones, often in synergy with Soletanche Bachy. They included development of the Bourdonnais port in Paris, construction of the Castel quay in the port of Bayonne, extension of the Quai des Flamands in the port of Cherbourg and the Rives de Saône development project in Lyon.

In Africa, group synergies won the new contract to extend the port of Lomé, Togo, in the wake of a similar project completed in 2012 in Cotonou, Benin 

Soletanche Freyssinet's subsidiaries specialising in ground technologies worked on a large number of port infrastructure projects around the world, including those in Puerto Brisa and Bahia Blanca, Argentina, Montevideo, Uruguay, Jebel Ali (terminal T3) in Dubai, Gemalink-Cai Pep in Vietnam and Barangaroo in Sydney, Australia - the last one a vast seafront redevelopment project for which subsidiary Menard Bachy is building the basement wall (a 13,000 sq. metre diaphragm wall and 650 ground anchors).
