It's certainly one of the four sisters GeoP, Maersk Anglia, Mearsk Flanders, Maersk Importer and Maersk Exporter, I sailed on a vessel which was on charter to Norfolk Line, the operator and used to meet up with the captain and chief every Saturday Morning in Vlaardingen for coffee and cakes!
They are now owned by DFDS seaways and have silly names like Anglia Seaways and Flandria Seaways, not sure about the importer and exporter though. For some reason they were known as the E class (I assume the exporter was the first of the class)
Apparently they were terrible ships to sail on in bad weather.
