Port@Lekki (located about 70 km East of Lagos, Nigeria) is a port development for chemical tankers (160,000 DWT) and container vessels (8,000 TEU). The layout of the new port, including the layout of approach channel, turning circle and harbour basins has been derived from optimisations based on port operations, construction costs and possible future extensions. Two different breakwater concepts were applied for the main breakwater: A rubble mound with geo-bag core for the near-shore sections and a composite breakwater for the more exposed sections. The secondary breakwater was replaced by a barrier. The barrier consists of a core from sand, internally fortified by a protective geo-bag layer, a revetment on the harbour side and an artificial beach on the seaward side. The proposed layout of the new port and the design of main breakwater and barrier are described in this paper.
