After a very short duration under Canadian flag the large offshore tug / supplier Maersk Maker has returned to the Danish registration. Built in 2019 under Danish International registration the tug was transferred to Canada February 4, 2020 for work in Newfoundland. However that work was apparently cancelled and it was then sent to Nova Scotia. It was in and out of Halifax for work related to the decommissioning of Exxon Mobil's Sable Offshore gas field, possibly setting anchors for the crane ship Thialf, then in supply/support.

It has been replaced in that project by Maersk Mobiliser another vessel of the same Starfish class of 260 tonne bollard pull.
Maersk Maker returned to St.John's, Newfoundland, via Bay Bulls, then sailed from St.John's May 16 for Aberdeen, Scotland. On arrival its Canadian registry was closed June 4 (effective June 1). It returned to Danish International registry and will be working in the North Sea spot market.
