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.
