The extension arm only allowing for a small lifting whip will not catch on. I have worked on projects where a 50 tonne crane has been performing 45 tonne lifts putting manifolds etc on the seabed. The industry will be looking for a more substantial lift capacity. What confuses me if they have integrated it into their existing controls then why not upgrade the existing crane and boom and don't bother with the rather light looking extension. market research may also be a great benefit, I worked for MPI installing offshore windfarms.
This was the vessel I was working on, once the pile is installed the pylon is attached. not possible to put a small container on top of the pile as per the video.

Certainly one sure way of getting a fixed lifting platform for heavy lifts at sea.
