4. CONSTRUCTION IN ARCTIC: MAIN CHALLENGES
4
AMBIENT CONDITIONS
• Kharyaga absolute minimum is -53 deg. C
• Weather/ seasonal restrictions for many activities
• H2S content, wax deposition at 28 deg. C
• Special materials, equipment and procedures
• Heat tracing/ heat insulation for all
piping/equipment is required
• Vital role of power generation (incl.
accommodation camp)
• Difficult logistics for goods and personnel
transportation

5. CONSTRUCTION IN ARCTIC: MAIN CHALLENGES
5
SENSITIVE ENVIRONMENT (Tundra)
• Short vegetation/ long recultivation period
• No access to Tundra from May to December
• Limited access to bulk building materials and their
stockpiling
• Permafrost: specific construction techniques
LOCAL CONTRACTORS/ STAFF
• Low QA/QC and HSE culture within local
Contractors
• Lack of EPC experience of local Contractors
• Very important local content required

6. ENGINEERING WORKS
6
• Conceptual / preliminary studies
• TDA preparation
• Cost estimations
• TEOC (FEED)
• Detailed Engineering
• As-build
• Authorship supervision is required during
Construction

7. ENGINEERING WORKS
7
MAIN CHALLENGES:
• Brown Field engineering mostly
• Not clear RF Norms & Rules, lack of Arctic
solutions
• Gaps between RF Norms and GS’s
• Specific engineering solutions for harsh Arctic
conditions
• Difficult to find mid-size engineering Company for
small projects/modifications capable to perform full
cycle of engineering works.
• LLI’s purchasing usually initiated based on the
conceptual design of CS

8. HSE CHAPTER
HEALTH, SAFETY AND ENVIRONMENTAL STATEMENTS ARE STRONGLY IMPLEMENTED BY
CONSTRUCTION SERVICES BOTH ON SITE AND OFFICE LOCATIONS.
IN OUR DAY-TO-DAY BUSINESS WE ARE CONTINIOUSLY WORKING WITH:
 MONTHLY HSE MEETINGS WITH CONTRACTORS
 REPORTING AND MONITORING HSE KPI SYSTEM
 HAZID & HAZOP STUDIES
 RISK ASSESSMENTS
 SAFETY ENGINEERING
MAIN CONCERNS ARE:
- NEAR MISS INCIDENTS RELATED TO LOGISTICS

9. CIVIL & EARTH WORKS
• Stabilized pads construction
• Access roads refurbishing
• Slopes renovation works (compacting, geo-textile
laying, geo-membrane anchoring, filling with fertile
soil and seeding arctic grasses)
• Drainage system reconstruction
• Skidding tracks preparation for rig move
• Slabs laying
• Construction materials providing

10. MAIN CHALLENGES:
• Main goal – preservation of permafrost
• Formal restriction access to Tundra at government
level
• Access to bulk building materials pits and their stock
piling in advance
• More or less single source contractor due to licenses
for sand/gravel quarrying
• Soil delivery in thin layers (20-40 cm) with through
compaction using 25t and vibro-compactors
• Snow layers are not allowed in between soil layers
due to possible sliding

12. 12 -
MAIN CHALLENGES:
• Brown Field
• Contractor’s safety culture to be further developed
• NO underground piping
• All piping with HT& HI
• Urgent works for Prod./ Inj. wells HU as soon as it’s drilled
• Low temperature (LT) grades only
• Gap between GOST and ASME standards - only piping as per ASME standard can be used
=> high cost and long delivery time (Stock to be organized).
• New wells hook-up
• Piping urgent repairs/ planned modifications
• Temporary utility lines construction
• Drilling rig move
• Assistance during WO operations

13. STRUCTURAL WORKS
MAIN CHALLENGES:
• Prefabrication/ preassembly in advance as much
as possible
• Impossible to paint on Site => dedicated Summer
painting campaign to be organized
• LT carbon steels (LTCS) to be used only (Russian
steel 09Г2С)
• Leader drilling & piles driving works
• Piping & cable trays supports construction
• Overheads construction
• Prefab/ installation of wells service platforms
• Wells shelters construction
• Ladders, steel frames, service platforms, fencing,
drip pans construction, etc.

14. E&I + ICSS WORKS
MAIN CHALLENGES:
• Limited temperature window for cable laying
• Humidity problems at negative temperatures
• Power supply redundancy is critical for winter time
• Full SD required for ICSS modifications (ESD, F&G)
• Possibility of ICSS extension is going to the limit
Electrical and Instruments works:
• HV equipment installation (MVD, VSD, switchgears)
• HT Systems installation
• Lighting, lightning, earthing installation
• WHCP installation / modification
• Infield devices installation
• F&G detectors installation
