| Résumé : |
Potable water for the city of Abu Dhabi in the United Arab Emirates is obtained by desalination of sea water. There are several power and desalination stations distributed all over the country. The largest of them is located in Umm Al Nar which has a 90 MGPD output and the storage is made in above ground steel tanks coated inside and outside. Besides these there are several smaller tanks for storing fire water, distillate, fuel oil etc. for the boilers and turbines. The soif on which they are located is notable for its salinity and the sub soit water level is very close to grade. Most of the tanks have been made more than ten to fifteen years ago and therefore were not provided with cathodic protection for the external of tank bottom. The corrosion has therefore set in at the annular ring plate and propagating to the centre. The rehabiIitation of some of the tanks has been done at very great cost and the newer larger tanks are provided with cathodic protection of better design. This paper deals with some of these aspects. |
