How are marinas built?
This varies in different parts of the world but the preferred method in the Gulf over the last few years has been to float concrete structures in the water and anchor them with massive concrete blocks dumped on the sea bed. Depending on the configuration of the floating dock it weighs generally between 10 and 30 tonnes. The anchoring blocks weigh from 2 to 3 tonnes and each dock generally requires 4 of them. So each berth will require between 18 and 42 tonnes of concrete to be put in the water. That is, from 900,000 to 2,100,000 tonnes of concrete to be added to the marine environment for the 50,000 berths to be built in UAE.
