it looks like Halifax Regular Italy Express, has returned from a work period, and has returned to her pre Hapag Llyoyd name of OOCL Vancouver.
Hapag-Lloyd and OOCL operate a shared service to Halifax. Some OOCL Vessels on the service were operated by Hapag-Lloyd and therefore took Hapag-Llyod “express” names. Presumably the charters ended, and this may be part of the reson why some vessels aggined to the new G6 service made early appearances.
