Daniel Cahalarn implemented a completions driven approach on the Hebron oil field project in Korea that resulted in significant benefits. By utilizing progressive inspections with a mobile 3D model, they were able to validate cable tray installation 25% faster. This improved schedule certainty and identified opportunities to pull more cable per week. Visualizing the status in 3D also found early loop testing opportunities. Overall, the approach improved safety, quality, and construction performance through focused planning, inspections, and influencing contractor behavior with accurate information.

6. The case for 3D CAD
Advisian / 6
3D model systems started being used in Oil & Gas over 30 years ago, and yet
at first there was much scepticism as to whether anyone could even design in
3D??

Its rise was driven by the ‘young designers’, the early adopters who were able to
demonstrate tangible productivity gains and significant reductions in field errors

• The Hebron oil field is located offshore Newfoundland and Labrador,
Canada in the Jeanne d 'Arc Basin 350km southeast of St. Johns.
• The field was first discovered in 1980, and is estimated to produce
more than 700 million barrels of recoverable resources.
• The water depth at the Hebron field is 93 metres (Mean Sea Level).
• The Hebron field is being developed using a stand-alone concrete
gravity based structure (GBS). The GBS consists of a reinforced concrete structure
designed to withstand sea ice, icebergs and meteorological and oceanographic
conditions.
• The GBS is designed to store approximately 1.2 million barrels of crude oil.
The Bull Arm site is the primary construction site for the GBS.
• The GBS will support an integrated Topsides deck that includes a living
quarters and facilities to perform drilling and production.
• A substantial portion of the Topsides is being engineered and fabricated in
Newfoundland and Labrador, with integration performed at the Bull Arm site
• Fabrication of the Derrick Equipment Set (DES) and the Utilities/Process
Module (UPM) of the topsides is occurring in Ulsan, Korea.

 The 3D model is enabled by the
construction management system
 Visualize & analyze what you put in
It can’t plan
It can’t execute
It can’t make decisions
 It can improve planning, execution and
decision making if used correctly,
… but, to work effectively status data
must be regularly updated!

“What is measured can be improved”
What:
 Proactive field status verification independent from what contractors
report
Why:
 Understanding the true status of the project at all times
 Early identification of opportunities and vulnerabilities
 Provides leading indicators for management decision making
 Keep contractors honest
 Drive contractor behavior
 Ability to commercially protect ourselves and our clients if required
Progressive Inspection – What & Why?
