Arctic and Cold Climate 


WorleyParsons and INTECSEA are world leaders in the design and construction of oil and gas production facilities located in remote, hostile environments. 

The Industry
Remote and hostile environments present numerous challenges for customers in the hydrocarbons industry including accessibility, logistical challenges, short construction seasons and tight delivery schedules. Arctic and cold climate conditions also present frozen sea, ice-bound ports and permafrost challenges for large float-overs.

A well-established track record and cold climate expertise has resulted in innovative and first-of-a-kind solutions implemented in our projects to solve the unique problems associated with revamp, modernization, and grassroots projects in these environments.  WorleyParsons currently has in excess of 500 personnel permanently stationed in Anchorage and Prudhoe Bay, Alaska to support these projects locally.

Our Services
WorleyParsons responds to these unique challenges with our logistics and installation experience to ensure project success and overall schedule improvements through value-based planning and management.

Planning grass roots oil and gas field developments in cold climates involves analyzing a number of variables and options, and investigating how they interrelate so as to achieve an economical approach. Our arctic and cold climate specialists have extensive experience in analyzing:

  • Extended reach drilling versus increasing the number of well pads
  • Number of central processing facilities
  • Process train size as a function of module size, production curve demands and cash flow
  • Module size as a function of impact on logistics, infrastructure and labor
  • Phased development versus cash flow
  • Fabrication and construction approach versus local content
  • Net present value of traditional design versus a fit-for-purpose design approach

Pipeline Systems capability for arctic conditions
Unique pipeline design aspects for arctic conditions include analysis of the potential effects of arctic-specific environmental loadings (ice scour, strudel current scour, permafrost), and the effective use of limit state design for extreme loading conditions.  Evaluation of these unique design-loading conditions and the use of a limit state design philosophy have been successfully used by INTECSEA for offshore arctic pipelines.

Innovative solutions
Our arctic and cold climate experience has been the foundation of our technical and commercial success in the engineering and construction industries. WorleyParsons collaborative brainstorming approach with customer shas resulted in innovative solutions to projects in the North Slope, the Beaufort Sea and Russian Arctic.

Innovation and new concepts are mandatory in the continuing development of arctic oil and gas fields. Without the willingness of our customers to explore new methods and ideas, these fields would never have been put on line.
