Applications to Deepwater and Arctic Arenas

2. Evolving Energy World and Challenges facing Hydrocarbon Projects
Leveraging Technology as Project Enablers
 Deepwater
 Arctic
 Adoption of technologies from other industries
Overview
Arctic
Deepwater

3. Evolving Energy World

4. United Nations Paris Agreement
 125 of 197 countries have ratified
the proposal of keeping global
warming to <2⁰C
 Forecasts estimate that fossil fuel
consumption needs to reduce by
35%
 A number of countries have
drafted their Nationally Determine
Contributions (NDCs)
Global Warming

5. United Nations
Paris Agreement
 Global warming is a significant
world issue and will impact how
energy is generated and
consumed
Global Warming

6. Renewable Energy
 Forecasts are predicting a significant increase in use of
renewable energy over the next 25 years
 Power generation capacity is significant > 50 MW
 Cost of Energy storage is reducing

7. Renewable Energy

8.  Battery Technology
 Electric Vehicles – Cars, Bikes
 How quickly will they change
the landscape?
New/Disruptive Technologies

9. Commodity Pricing
 Reducing available Capital for projects
 Forcing industry consolidation
 Reducing available resource capacity
 Experienced personnel and knowledge base are
retiring

10.  Reduced CAPEX solutions
 Accelerated Delivery schedule
 Ensure certainty of outcomes
 Compete Globally for funding
 Respond to how hydrocarbon energy is
going to be consumed
The Hydrocarbon Industry Challenge

11. Leveraging Technology
Deepwater

12. Industry Examples
 International Association of Oil and
Gas Producers IOGP – JIPs
 OG21 – TTA4 Report Subsea cost
reduction
 DnV·GL – RP Subsea Forgings
 Are we moving quickly enough?
Reduces Complex Component pricing;
Accelerates Delivery
Standardization
JIP 33

13.  Increase productivity due to greater pressure
drawdown
 Reduce CAPEX/OPEX by reducing surface processing
needs
 Overcome backpressure to allow extension of
production life
Many pumps deployed. Projects moving to continual
use
Subsea Pumping

14.  Composite Materials – high flexibility
and homogeneous
 Smart Materials e.g work by BP
International Center for Advanced
Materials
 Intelligent - Alloys that can trap Hydrogen
and neutralize its embrittlement impact
 Self Healing – Coatings that can sense
damage and react – Micro capsules of
healing fluid

15. Deeper Floating Facilities

Many projects require large floating facilities to deliver the reservoir. Although these are significant engineering successes, they require CAPEX

16. Overall field development
CAPEX reduction
Motion in 100 year extreme
 Heave < 0.2 m SA maximum
 Pitch/Roll < 1.9 deg SA maximum
20%
 Enable use of SCRs instead of flexibles or
hybrid risers to access subsea wells, from
200m to 3000m+ WD
 Allows use of Top Tension Risers and dry
trees to drill and/or complete some wells
from FPSO
 Can eliminate the turret, and use
conventional spread mooring
 Confirmed by model testing and Approved in
Principle by certifying authority

17. Leveraging Technology
Arctic

18. Ice gouging (scouring) is the most
unpredictable event for design
 The pipeline may not be able to
withstand the ice contact loads and
may need to be buried and backfilled
 The burial depth of the pipeline is
determined using finite element
methods
 Trenching & backfilling is considered
the most effective means of protection

19. Enabling Arctic Technology – Evaluation of PL Strains
 Numerical modeling of ice keel/seabed interaction
events has moved to Continuum FEA Methods
 Couple ice keel/seabed/pipeline interactions – that
is modelling the ice gouge, soil movements, and
pipeline response in one model
 Results show burial depths are reduced compared
to original methods which used discrete soil springs
 More work required on calibration and validation of
these models
Offshore Arctic Pipelines - Ice Gouging
Significantly reduces required trench depth impacting CAPEX and
construction schedule

20. Need to economically and effectively trench pipelines over
long distances in Arctic and “frontier” regions
The trenching system must:
 Achieve up to 7m burial
 Be mechanically reliable
 Be able to handle a wide range of soil conditions
Research and development is needed to bridge the gap
between what is currently available and what is needed for ice
scour environments
Solutions are required to achieve deeper trench depths
within construction windows
