Intensive study of corrosion problems for pipelines buried in highly saline desert areas, known as Sabkha in Abu Dhabi, led to replacement of lines aboveground, rather than buried, and to a change in their external coatings. The investigations examined the factors affecting the choice of aboveground or underground installation of pipelines. The factors were pipeline operating temperature, soil conditions, environment, installation method, and aesthetics. Among the study`s findings were that the required cathodic protection (CP) is fundamentally different: aboveground pipelines only require small-scale CP systems at buried road crossings, whereas buried pipelines need protection over their entire lengths. The study also compared the risks of coating deterioration and external corrosion on buried pipelines with the simplicity of external inspection and maintenance on aboveground pipelines.
