Slide 4

Aker Arctic was established in 2005 as a spin off from Aker Yards. We made a 12 Mill. EUR investment to create an unique unit of engineering and design resources combined with an ice model test basin

The independent role – separation from the shipyard – opened up the global market, something which had not been possible earlier

Aker Arctic



Slide 5

We have a good laboratory and have kept it updated to meet the market needs� A new third generation test facility

erected in 2005, � investment 10,3 Mill. €� Beam increased to allow larger

structures to be tested� Glass bottom to improve observation � Latest technology for freezing

process� Latest technology for data

recording� Best in the world

Slide 9

The investements in new mooring systems have been well utilised, and new innovative solutions have already been developed and studied further

Aker Arctic



Slide 10

We have continued with various tests for major oil companies for the Beaufort Sea conditions. We can honestly say that we are now able to simulate any ice conditions found on the globe!

Aker Arctic



Slide 11

We have invested in a modular false bottom system for shallow water tests

This has mainly been used for Caspian Sea projects and also in BP Alaska North Star artificial island berm tests.

Slide 15

Aker Arctic aim is to develop transportation and logistic systems for the Arctic areas

• We are serving mainly Oil, Gas and Mining industry with innovative and cost effective ship designs for different purposes.

• Our co-operation starts typically at a very early stage of the project with ice field research in the area.

• Recent examples of our work in Russian Arctic include Varandey and Prirazlomnoye oil shuttle transportation projects and Norilsk Nickel project.

Discovery of the stern-working”Double-Acting” (DAS™) principleTests in the Gulf Bothnia:� Performance similar to icebreakers due

to reduction of friction by the propeller stream

� Successful running backwards when moving ahead was already impossible

� Could not get through ridges which already were penetrated astern

� Learned a new way of operation� Ridges were ”destructed” with the

propeller stream from below� GREEN TECHNOLOGY, energy saving

up to 50%

This required investment in Azipod development and ownership and operationof two tankers in 8 years of Arctic trade !

CCG IB John G DiefenbakerAker Arctic participates in the Design of the Canadian Coast Guard’s new Polar Icebreaker

Aker Arctic is a member in the team led by local STX Canada Marine that have been awarded the 9.5 M CAD contract to design the new polar icebreaker for the Canadian Coast Guard. Expected to take 24 months to complete, STX Canada Marine Inc. will advance the design work to the point where a comprehensive design package can be provided to Vancouver Shipyards Co. Ltd. to build the vessel.

The new Icebreaker will be delivered to coincide with the decommissioning of the CCGS Louis S. St-Laurent in 2017. The polar icebreaker contract has been awarded to Vancouver Shipyards Co. Ltd. The vessel will be designed and built in Vancouver. The polar icebreaker will be designed to accommodate 100 personnel with space for 25 additional people and have the ability to break through 2.5m of ice at 3 knots.

STX Canada Marine will be supported in the Polar Icebreaker Design project by a team of highly experienced partners including Aker Arctic Technology (AARC). Aker Arctic will provide their world leading icebreaker design and construction expertise to the project. Aker Arctic’s main roles will be assessment of the ice loads, development of the hull form and structure, propulsion conceptual design and descriprions on winterisation principles.

Ice conditions (ice types) Can’t be controlled. Should be predicted.

Ice speed vi Can’t be controlled. Should be predicted.

Vessel speed (average) vv - Depends on the IM vessels ice performance in different ice conditions.

- Should be defined (model- and full-scale tests). Speed of IM vim Depends on vv and fim

Distance between IM circles fim - Effects to the intensity of CIM (the smaller fim thehigher intensity)

- Effects to the vim (the smaller fim , the lower vim)Width of circles w - Depends on the ice forecasting accuracy.

- Determines the intensity of CIM (the smallerthe circles the higher the intensity.

Aurora Borealis Slim

ERICON-Aurora Borealis is an EU funded project aiming at developing a pan-European solution for Polar monitoring and research.The first vessel proposal was based on work done under a German Government’s grant and unfortuntaley lead into a very expensive solution causing the EC to drop the project from the ESFRI list of prioritized joint research infrastructure projects in Europe.Now Aker Arctic has been asked to come up with a ”SLIM” cost efficient alterantive, based on new technologies available in 2012.ERICON Stakeholder Meeting in Rome in October 2011 accepted this SLIM version as the basis for the final ERICON report and proposal to the Commission.

Aker Arctic



Slide 111


Proposed detailed modifications

• Main dimensions are reduced, length with c. 40 m beam with c. 12m• 2 moonpools changed to one combined • Purpose built fixed drilling equipment excluded• DP requirements are simplified• Shaft power output from 81 MW to 45 MW, 4 engines instead of 6• Shaftlines replaced with azimuth thrusters• All six retractable thrusters replaced with two tunnel thrusters in bow• STOL aircraft facility replaced by helicopters• Two large deck cranes are installed instead of three• Large fast trimming system is not needed• Fin stabilisers are not installed• The flying bridge is replaced by a traditional one

Slide 112

Aurora Borealis SlimAdvantages of current slim ship design

• Initial cost reduction about 1/3• Dedicated purpose built Drill rig cancelled• Same accomodation spaces as originally or even more• Same research function and spaces or even more• Container capacity is almost equal• Container handling improved• Ice going performance improved• Station keeping in ice possible due to azimuth thruster concept• Capable to turn in design ice condtions• Lower fuel consumption, costs and emisions• Guaranteed 90 days endurance• Tank capacity larger than original• Reduced draught allows wider operational areas

Aker Arctic



Slide 113

Aurora Borealis SlimTechnical requirement

• scientific requirements and capabilities have been kept• accomondation space as earlier• 90 day duration of operation• icebreaking capability 2.5 m thick level ice at 2-3 knots
