In Ghana, the future Tema Port should be put into service on June 28th 2019. This port, initiated in 2004, will be the deepest sea port of the country. The Quay wall construction begun for MPS, the consortium gathering Bolloré Ports, Ghana Ports and Harbour Authority and APM Terminals. A trench has been dredged in the seabed 19m deep to receive the 74 caissons which will compose it. These concrete blocks, of 1000 cubic meters and 2600t each, are moved onto a floating dock by rolling them on inflatable air bags. Once on the platform, they are forwarded until the trench location. On the spot, the dock is sunk, which allows the caissons to float and to be transported until their final position with tugs. The last step consists in sinking the caisson and fill it with sand to solidify the framework and then cast the deck of the quay on top.
