Bombing an underground pipeline

Is it underground?
I assume not, from this little tidbit:
and over the craggy Hajar mountains

But I could be wrong (it's happened before).

the 370-km (231-mile) Abu Dhabi Crude Oil Pipeline buried in the desert...

Very few petroleum pipelines in the world are placed above ground. Unless you have to avoid melting permafrost, it is far cheaper and less expensive as well as safer.

I found a better link to confirm the underground construction.

The pipe is first welded up above ground next to where it will be installed.

Then sidebooms (bulldozers without blades but a side crane and counterweight) will drive along together picking the pipe up and laying it into the trench.

When completed, there will be an access road next to the pipeline and a berm over the pipeline. This is typical of pipeline construction. In the US, we typically don't install the berm but rather bury a little deeper.

I've worked construction for a similar construct through mountains and flatter areas in the middle east. Let me know if you have other questions.
