The most technologically advanced drillship in the world is not on lovaton in the gulf of mexico or in a Korean shipyard. Actually it’s not even built yet. Meet the Aurora Borealis, a dynamically positioned, drillship/icebreaker, arctic research vessel designed for the European Union. The official website tells us;
The Research Icebreaker AURORA BOREALIS will be the most advanced Polar Research Vessel in the world with a multi-functional role of drilling in deep ocean basins and supporting climate/environmental research for the next 40 years.
The new technological features will include azimuth propulsion systems, satellite navigation, ice-management support, deep-sea drilling under a closed sea-ice cover and the deployment and operation of Remotely Operated Vehicles (ROV) and Autonomous Underwater Vehicles (AUV) from one of the two moon-pools.
The unique feature of the vessel is the drilling rig, which will enable sampling of the ocean floor down to 5000 m water depth and with 1000 m penetration into the seafloor at the most inhospitable places on earth. The drilling capability will be deployed in both polar regions and AURORA BOREALIS will be the only vessel worldwide to undertake this type of scientific investigation.
Technical Details:
• Powerful icebreaker with ca. 55 MW (diesel-electric)
• Highest classification for icebreakers
• Twin hull
• Two moon pools 7 x 7 m each
• Dynamic Positioning System
• Deep-sea drilling under a closed sea-ice cover
• Drilling rig: max. 5,000 m water depth and 1,000 m core
• Riserless drilling technology
• Modularized mobile laboratory systems – mission specific laboratories
Length over all ca. 180 m | Beam ca. 40 m | Personnel (crew + scientists) 120 | Expedition duration 60 days.

UPDATE: The BBC has just run an excellent article on this vessel which can be found HERE.

I wonder that twin propellers resulting more possibilities of propeller-ice interactions. Single pod could have been an alternate choice from manufacturers. Of course twin propellers have an advatage of using smaller diamter thus creating more hull aperture.
How will the vessel be dealing with drifting ice while drilling? Does it mean that the vessel still requires ice management by suitably deploed other ice breakers.
One more item is that as the number of special personnel on board the vessel will be much more tha 12, the vessel is going to be a special purpose ship (SPS) satisfying IMO Res A 534(13). Please confirm.

nice thinking n technology but can u [please also put an article on hoe can we think about the future propellers i.r. the propepellers of the fifth generation
