On peut donc voir que, si le pipeline de l'Alaska est construit en premier, on pourra ensuite augmenter sa capacité tant qu'il y a suffisamment de réserves en Alaska, ce qui retarderait de beaucoup la construction du pipeline du Mackenzie.
For that reason, it is pretty easy to understand that if the Alaska line were to go first, it would then be expanded for as long as there is sufficient reserves in Alaska to support expansions, and the Mackenzie line would be delayed significantly.
