BP did not even want to build the pipeline.  BP had hit in the North Sea and delayed North Slope development at every opportunity.  Some say the SS. Manhattan super tanker through the Northwest passage was simply a delaying tactic. Quasi independent Atlantic Richfield pushed to build the pipeline.  Without ARCO, it would have taken years more while BP kept Alaska oil in their bank, and more importantly on their world reserves with all the corresponding financial implications.   For the first time in forever, BP and Alaska interests have aligned.  Leave it in the ground is best for Alaska.  Better than paying to take it out.
