Working process

Task force formed

Task force meeting

Collect assumptions and status

Produce pre-read status document

Open industry workshop

Workshop summary input to Task force

Task force meeting

Draft report

Prepare for second workshop based on

input gathered

• Open to industry • Key note presentations • 5 min. floor presentations • Q/A sessions • Group work • Data collected

• Discussion on input • Delegation of themes within Task force • Use of Task force members networks

Main findings and conclusions

• Although past and present Oil and Gas activities in Arctic conditions provide a source of experience it should be recognised that moving into the High North presents more extreme and complex challenges than hitherto tackled

• Geographical conditions in the High North will require the use of both floating and fixed installations,  for  which  a  progression  of  today’s  global  technology  should  be  sufficient  to  provide  the physical designs.

• There is a need to improve data on met ocean and sea ice conditions and for this information to be

incorporated into improved design standards

• In some locations soil conditions present challenges for fixed installations • Year around operations using floating installations will require a mooring and riser system that

allows for rapid disconnect and reconnect in ice infested water

• Due to extreme weather conditions, and their complex combinations, along with the lack of infrastructure the manning and safe operations of these platforms will be the area requiring the most creative thinking and improved technologies

Design specifications and ice actions standards

Existing technologies, methods and best practices • ISO 19906 as basis when calculating ice loads on

structures

Common technology challenges • Numerical simulations and methodology seem to be the

area where the technology level needs to be significantly lifted to meet the industry needs for safe and cost effective solutions

Need for technology development and innovation • Further research to improve data on met ocean

conditions

Fixed Installations

Existing technologies, methods and best practices • Artificial Islands widely used • Gravity Based Structures (GBS) with skirts and piles used

in waters with challenging soil conditions

Common technology challenges • Shallow waters with occurrence of Stamukhi • Soil conditions and foundation design • Large size and complexity in designing arctic platforms Need for technology development and innovation • Further development of technologies and methods used

to install GBS on weak soil • Harmonization of Russian and Norwegian regulations to

promote cooperation and innovation

Floating Installations

Existing technology, methods and best practices • Cylindrical hull concepts • FPSOs with ice strengthened hull and ice breaking

propulsion Common technology challenges • Hull design that combines operability with resistance

against different types of sea ice • Rapid disconnect and reconnect • Icing of topside equipment Need for technology development and innovation • An efficient disconnect/reconnect system for mooring

and riser for use in water depths from 100 m to 350 m, probably be based on turret technology

• Development of analytical design tools for ice loading and conduct bench mark assessments on full scale ice load on moored structures

• Winterization methods and enclosed topside modules

Materials

Existing technology, methods and best practices • Reinforced concrete composite consisting of

water/cement chemical compound, aggregates, air-pores, steel reinforcement and pre-stressing steel

• Category E steel and plated steel for FPSO ice belt Common technology challenges • Complexity of corrosive-erosive wear • Quality of steel and welding to be used in extreme cold

temperatures • Abrasion of concrete structures

Need for technology development and innovation • Further research to the reduction of corrosion and

erosion effects is needed

Marine Operations and Operational Philosophy

Existing technologies, methods and best practices • Generally the same as for vessels and installations used

in exploration, development and production of oil and gas

Common technology challenges • Vessels, methods and equipment used in installation

operations in low temperatures and ice covered waters • Infrastructure and vessels designed for use in escape,

evacuation and rescue (EER) operations • Monitoring, sensing and forecasting used in EER and Ice

Management operations Need for technology development and innovation • Development of concepts for EER from platforms in sea

ice conditions, along with the means of transportation over, or through, these ice fields to a safe haven

• Designing, constructing and deployment of multipurpose hubs and multitask vessels

Technology/solution providers

• The Project activity has created new and expanded existing Russian/Norwegian Industry networks and provided a platform for the exchange of current knowledge and a better understanding of the common challenges

• A matrix of Industry solution providers

has been produced which hopefully can be used as a reference in future work

• The Focus Area report has identified 156 companies providing technologies and solutions relevant to floating and fixed installations in the High North.
