Yes, Triton is an older ship by now.
A patrol frigate for arctic conditions.
A warship always patrols Dannebrog when in Greenland. Partly to act like a tender, helicopter platform, hospital, rescue vessel and on rarer occasions an icebreaker.
And it has happened that the escort vessel has had to step in. Early on in FX&QMs marriage, on their first trip to Greenland I think, the weather was atrocious as it so often is, so the DRF members had to board the escort vessel to go by helicopter to a destination inland. Queen Mary later told that this was a new and slightly unsettling situation for her, because for once she had to remain passive and let someone else, albeit very competent, handle everything. I.e. entrusting her safety in the hands of strangers in what may have been a somewhat alarming situation for her.
There is nothing odd in Dannebrog making a detour or two while there. After all that's one of the reasons volunteering for conscription to Dannebrog is so sought after. The conscripts get to see something they might otherwise never see. Like whales in an Arctic fjord.
ADDED:
Triton is an interesting ship, for those interested in such things.
A patrol-frigate for arctic conditions, she is lightly armed but carries a heck of a lot of additional equipment you'd hardly ever see on other frigates. Apart from that her hull is reinforced so she can break ice up to a considerable size.
But the most striking difference is her crows-nest.
Above the bridge you will notice a thick mast, with a radar dome on top. Just below that are windows - the crows nest.
Ships that sail in arctic waters have crows nests. Period!
From the bridge you can only see that far, from a crows nest you can see further and you can also peek above minor icebergs, better access cracks in an ice-field and better see if there is something orange in the water. It also helps to better judge how stable an iceberg is. Because you know only a tenth of an iceberg is above water. - And if an iceberg is unstable it may suddenly turn over and that can seriously ruin the rest of your life if your ship happens to be too close... But sometimes you can't avoid having to sail past such a thing.
All that is something a radar can't tell you.
Beforehand such a crows nest was basically a large mug attached to the foremast, which you climbed into and after a short while you were
very cold!
Titanic also had such a crows nest on her foremast. Enclosed, pure luxury at the time, but no heating. So the lookouts, there were always two, had a bottle of brandy to help keep them warm. There was also a phone line directly to the bridge. It was very modern. And as you may recall the lookouts did try and contact the bridge, but..
Today such a crows nest on a modern larger ship is spacious, heated, comfortable and equipped with all kinds of observation-gear. But smaller Greenlandic fishing vessels and smaller patrol boats still have an open crows nest. Because it's simple and it works. No windows icing over, no extra cost, and very little extra weight.
