Eric - I think you're right. Not sure of what was happening on the Dutch side at that point - The merged company "Schreiner Northsea" operated for a few months in both Norwich and Den Helder before the contract was pulled in early spring 1998.
It was a bit of a reverse takeover as you described - the name was Schreiner but the ops and infrastructure seemed to move across to the KLM model, presumably as you say, to give the infrastructure that it was thought the Oil co's wanted.
Not happy times and i take no satisfaction from the fact that Bristow's crews now find themselves in the same situation.
