colours, the reef is integral to the Gulf’s marine ecosystem. Pink, sea floor, providing shelter to the many species sharing this unique environment. Port Khalifa’s 8km-long environmental breakwater protects this vitally important underwater world. Built at a cost of US$240 million, the breakwater rises 4m above water. It has two main sections – an inner breakwater to protect the sensitive coral reef from contamination, turbidity and unwanted temperature fluctuation caused by port operations; and an outer breakwater to reduce the wave action within the port area. The reef’s foundation is core material, covered with a strong synthetic geotextile like heavy canvas, covered in turn by rock originating from Ras Al Khaimah that has been cleaned to prevent contamination. The outer section has an extra layer of acropod blocks – man-made unreinforced concrete structures designed to resist the action of waves

Offshore Port island L
ocated 4.2km offshore, Khalifa Port has been constructed on a 2.7km2 reclaimed port island.
With a platform, causeways and revetments formed from 45 million m3 of dredged materials, and designed to meet stringent seismic criteria, the port island is large enough to host some 340 football pitches. It is joined to the shore by the north and south causeways and the 1km-long road and utility bridge. Rising some 24m from their foundations on the sea bed, the quay walls are equivalent in height to six double-decker buses. Formed from 12 blocks, with a maximum weight of 71 metric tonnes each, around 4m of quay wall is visible above the water line. With ABOVE: Placing of quay blocks.
stringent specifications for block placing tolerances of +/- 20mm, the wallâ€™s foundations vary in depth to accommodate a range of geotechnical conditions. The portâ€™s container yard features six ship-to-shore quay cranes, 30 automated stacking cranes and 20 shuttle carriers. The onshore port area, which connects the port with Kizad, will host customs, immigration, container freight, inspection and security facilities
