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 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™) principle Tests 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%

CCG IB John G Diefenbaker Aker 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.

Historical development of thinking

”Percentage formulas”, additions to open

water design 1920-1960

First scientific attempts, Russia & Finland late 1960´s

First Finnish-Swedish rules for Baltic Sea 1971

First Russian and Canadian rules,

most Classification Societies adopt

Finnish-Swedish rules as

Subarctic standard 1970´s

New Arctic rules:

DNV, CAC, RMRS, ABS, Lloyds 1980´s

Attempt to harmonize the rules,

IACS (IMO) PC rules 1990´s – 2007(?)

Harmonized PC rules probably emerge (IMO Polar Code)

Aker Arctic



Slide 64

Hull dimensioning philosophies

Direct design to known ice conditions Requires thorough understanding of actual ice conditions,

nature of ice loads, response of structures & systems

”For expert organisations only, when new ways to operate emerge

or new challenging geographical areas should be navigated”

Design to an Ice Class Normally easy to use formulations for minimum hull scantlings,

engine power and propulsion strength etc.

”For well established traffic in a familiar environment, traditional ways

of operation”

• Hull structural strengthening

• Propulsion system reliability

RS has elaborated a set of requirements for structural strength of hull members

under ice loads, with a new concept of ice classification by the basic

ship motion regimes introduced.

RS Rules cover requirements for the propellers of ice ships and icebreakers,

strength and materials of components.

Comparison of Ice Class Rules

There is no absolutely correct method to compare the Ice Classes of different Rules

Equivalence depends always on:

- Ship type

- Ship size (displacement = mass)

- Hull form

- Hull area to be considered (bow, midship, ster, bottom)

- Structural item to be considered (shell plating, framing etc.)

- Engine power

etc.

Slide 79

We are working with Classes and

propulsor suppliers, assisting them to

come up with right rules and right ice

dimensioning

We have continued working with LR, BV and DNV, assisting them to

develop rules and guidelines for proper dimensioning of vessels and

equipment as well as giving them experience and measurement based

knowledge to these processes.

This is very much based on the extensive full scale mesurements over

the years creating unique databases for the Company. This is part of our

role to a global center of excellency. in a similar way co-opeartion is

underway with Thrustmaster, Rolls-Royce and Steerprop.

Slide 80

Propulsion suitability for ice navigation

Aker Arctic



Slide 81

What do we get with an Ice Class ?

Extra steel to hull, typically +2% to +20 % depending on Ice Class Stronger propeller, rudders, thrusters etc.

More expensive ship !

Ice Class gives minimum protection against dangerous damages,

it is acceptable that damages still occur, Cost vs. Safety,

Owners responsibility to select Ice Class

Standard ways of operation assumed, e.g. 1A Super Ice Class

does not guarantee safe icebreaker type independent operations

Motto:

New vessel designs and new operational practises must be used with

caution, ship performance and structural performance must be

monitored and experiences collected actively, no shortcuts

Slide 94

New vessel designs for NSR

RMRS classes give some guideline to the NSR conditions, but have no mandatory role like to Finnish-Swedish Ice Classes in the Baltic Sea

PC classes are not ”ready” yet and progress with IMO is expected to be quite slow

Owners may let experts assess their existing ships (Ice Certficate is anyhow needed)

For newbuildings Owners need to define

- target operation areas

- target operation season

- target performance level

From this framework specilist designer are able to tailor the optimum solution variants for economic assessment and evaluation
