I would expect 'Egeria' is destined for the charter market, though you never know. Given the vessels flexibility, and ability to fit nicely in most ports, Visenitini's high capacity ect. Perhaps she might find work in New Zealand, or even South Korea.
There is also the possibility the group are examining the performance and competency of the Chinese yard, perhaps with future builds in mind. Stena have always been keen to get a bargain so to speak, have this be in Yugoslavia (Stena Londoner /, Seafrance Monet) , or South Korea (Stena Transporter - 1978 & Stena Adventurer - 2003). Stena wouldn't be alone though, Norfolk Line chose South Korea to build the 3 D's, but personally I think Stena led the way so to speak. I think P&O are the only group with a nearly all European built vessels, with the exception of the Ambassador class (European Highlander & Causeway, & Stena Nordica).
I don't know if its just me or does the 'Egeria' bring back memories of the Stena Forwarder (2002 ish).
