Pipeline Engineering Steps in Cold Countries like Canada ? 1

[hirad75]

Hi dear friends
I am a mechanical engineer with some pipeline engineering experiences in middle east and tomorrow I have an important interview for position pipeline engineer with a company in Canada, and success in this interview is very important for me because I need this job.

So may you please inform me from pipeline engineering steps for buried pipeline projects in a country like Canada? As you know, the big difference between pipeline projects in Canada and middle east is ambient temperature, and also other differences that I am not aware from. So I think those different parameters can affect engineering steps of pipelines.
Please guide me!

Regards
Hirad

The biggest differences:

* Different Codes of Design and Construction; here the Code is CSA Z662
* Provincial Regulations differ from Province to Province, and the Regulations take precedence over the Code;
* Muskeg is common, so this means soils with low undrained shear strength and long virtual anchor lengths, giving rise to extra challenges related to thermal expansion and buoyancy control;
* Understanding the relationships between installation temperature (the temperature of the pipe at the time of initial restraint), combined longitudinal and hoop stresses, rope bend radii and design parameters that govern in the selection of wall thickness;
* Seasonal road bans and predominantly winter construction windows that fluctuate depending on when "spring break-up" arrives;
* the risk of having an entire pipeline project canceled because of local Native burial grounds or one single trapper's objection to the right of way infringing on his muskrat trap line.

Yep...we're special up here.
