The pumps for Keystone were built by the Sulzer corporation and have been sitting in long term storage for some years now. It is my understanding that they are being 'reassigned' for other uses (not sure if it is this one or not). These pumps are a 48-52 week lead item. Meaning if the project is approved, that cycle would start over.
That only means it would start from a normal cycle. No way the rest of the pipeline, including ordering, receiving and installing the main pipe it self, could be done in less time. Ordering the pumps upon permit approval would not cause a delay in the final start up. Too many other activities would need to be done.
The detail engineering alone will take over a year to complete.
