What's the large pipe on top of M/S Viking Grace?

What's the large pipe on top of M/S Viking Grace? - Mountain Covered by Snow

It looks really weird and I can't understand its purpose. Is it for making the vessel look better? An exhaust? Does anyone know what it it? Apparently it didn't have it in the beginning and it seems it's been moved after being put on the ship. It's rotating and it's glowing during night.

  • What is it?
  • Why was it moved?
