I read it slightly differently, in that some of the finance requires a guarantee since it is a slightly different use case to the one KBR supplies for.
KBR then offered a guarantee which requires some extra time to test out. The guarantee of plant therefore would result in a guarantee of funding.
That seems sensible, as it's best to nail the equipment spec before committing funds.

I think the company might have laid out the detail a bit more clearly, perhaps they cannot at this stage, but their job is better focussed on delivering the project which they seem to be doing. Have a look at QPM's LinkedIn page and feed, to see how many industry professionals are watching the progress.
