Aero could try leasing but its a leasors market at the moment and who has modern helicopters that would lease out? Well, Seacor maybe but the fees would be steep if only to cover the possibility of not being able to extract them post-lease.
I can't see an independent Aero being able to retain the skills of infrastructure being able to satisfy Chevron or Total.
They may predate CHC but the Dutch ran the show before CHC bought them out.
I suspect the FCPA requirements that First Reserve will be imposing will cripple the rather free (almost Gallic!) way we Canadians do buisness overseas.
