You simply have no idea what you are talking about.
Pipeline maintenance is not simpler above ground. All that structure and slide plates create more wear points and expose it to more damage and corrosion.
Pipelines above ground expand and contract with the temperature variations. From day to night, the steel moves and special wear plates have to be maintained and replaced as needed.
We don't inspect pipelines by walking around them, stripping off insulation and coatings. We run smart pigs through them that measure the corrosion and check the integrity.
Pipelines, including the Trans-Alaska Pipeline, are buried when the can be for good reason.
Pipeline sections above ground are far more susceptible to damage.
Since I am ignorant regarding the mechanics of the oil industry and would like to gain a little knowledge...
Why not build new refinery abilities closer to the source? Is it related to water availability?
Why doesn’t Canada build their own refineries and just sell us the finished product?
Because I would certainly prefer to buy from Canada than the Middle East.
Let China buy their energy from Saudi Arabia.
Thanks Tom for dishing out eductation to those who are clueless on oil/pipeline issues. Thanks for your contribution to the TAPS when you ere here...
