It is difficult to keep track of all the container ship schedules these days, since there have been "blanked" sailings, where the ships have bypassed the Port of Halifax. This may be because of delays in other ports, and owners are trying to make up time by skipping smaller ports such as ours. Interestingly there have also been unscheduled arrivals. These are container ships that are not regularly scheduled for Halifax, but are deviating from regular routes to stop here or they are "extra loaders". Due in the early hours (that is while it is still dark) of October 21 is one such "extra loader", MSC Pamela. It has been anchored off Halifax since October 19. (Way out in the anchorges there is heat distortion and a maxed out lens that fuzzify the image. Those are fishing vessels on the far background, and the Mars Rock buoy H9 in the foreground.)
(For more info see: Mars Rock on the Maritime Museum of the Atlantic's Marine Heritage database.)
Samsung Shipbuilding + Heavy Industry Co built the MSC Pamela in 2005. It is a large ship at 107,849 gt, 110,592 dwt, with a capacity of 9178 TEU including 700 reefers. While it does not appear to have much additional container capacity, it is apparently coming in to pick up empties.
Many ports, particularly in Europe, are so clogged with empty containers that they have been refusing trucks entrance to the port if they are hauling empties. These extra loaders are sent to retrieve as many empties as they can to return to Asia.
