EO meaning European Operations i'd imagine.
Thai Aviation Services will cut ties with CHC any time I believe, going to 4xS76D and 2xS92. A lot of the expat pilots have now been let go from Nakhon Si Thammarat base, and it appears only the Canadian guys who are well established within the CHC/TAS family, will remain, being offered, (rumours again) to remain working for TAS on TAS contracts. TAS were paying more than CHC, up to $180k US I heard. Thats more than the CAD$145k they were getting.
It's at times like this where you begin to see who is best friends with who.
