“…In the panel data collection process, we presented the data for the period 2002-2008 to each port's or terminal's administration for their update data for the period 2009-2014 and for their remarks and rectifications. The container ports identified in Schøyen and Odeck (2013) and also analysed in this study include six Norwegian (Oslo, Borg, Moss, Larvik, Ålesund and Kristiansand), three Swedish (Gothenburg, Stockholm and Helsingborg), three Danish (Aarhus, Aalborg and Fredricia), one Icelandic (Reykjavik), four Finnish (Helsinki, Turku, Rauma and HaminaKotka) and three UK ports (Southampton, Immingham and Grangemouth). In Finland the two ports of Hamina and Kotka merged into one company in 2011, with the new name Port of HaminaKotka Ltd, and therefore from 2011 onwards the port authorities had the policy to inform only overall data for the merged port.…”
