The supply vessel Troms Castor arrived in St. John's July 7, 2013 from Norway, along with fleet mate Troms Capella. These vessels will service the drill ship Stena Carron when it arrives. The Troms Castor was last here in 2009, but I think its the first visit for the Troms Capella.
Troms Castor was built in 2009, has a gross tonnage of 4,366. The Troms Castor is shown in the photos.
