It has been dealt with before. The North Sea has already built up experience in this weather. Farther north is just more of it.
Unfortunately this does not begin to compare with Baffin Bay and the East Greenland Sea. The bergs there are huge and thick as grass. Not to mention this little matter of the sea freezing over for eight months of the year. Not that that necessarily stops the big bergs from moving. How are you going to do this dance when a monster berg is approaching and the sea ice is four feet thick?
