They never wanted the offshore work.
Babcock International purchased Avincis for the government and SAR work; it fitted with their core business of trousering as much of the defence budget as possible, and they were planning to expand/steal the SAR markets. Having failed to achieve that, I can't blame the parent for wanting to beat a swift repeat.
Added to that, I would guess that INAER may have changed the branding to Babcock, but is still very much INAER.... take that how you wish.
