I have been lucky enough to work in an oil n gas consultant company, with HQ in England and based in Indonesia (well it one of the branch in the company that mainly a survey company anyway).
Being in Laser Scanning division, I have tried various software that can utilize and modelling of Point Clouds data gathered from Laser Scanning Device, namely Leica High Definition Survey series, specifically for as built surveys.
Why are modelling of already built facilities are required? There are many reason for this, and the answering key are ‘Spatial’.
Suppose of a facilities need to be equip with a new installation, how do you measure and built the installation to be perfect fit in the already crowded facilities? (example: an offshore platform). The answer is quit simple, you need an exact 3D as built model of the facilities.
With so many Oil n Gas operator worldwide and vast amount of software format both intelligent and primitive, the task of modelling an as built oil and gas facilities are quite a challenging process.
For the consultant, getting the right model format ready to be use by operator are critical.
In this section I will try to explain those programs use by Laser Scanning variables in a simple way
This are my few samples of it:
This is a modelling made in Cyclone. A native modeller program from Leica Laser Scanning Device (HDS and Scanstation series). It’s simple to operate and can be use for various task (spatial in oil n gas, virtual survey for topographic, volume count in coal mine, etc.)
One of the most program used for EPC consultant or Oil and Gas operator are PDMS.
This are the same facilities as pictured above in PDMS:
The PDMS model can be registered as primitive or intelligent model. The intelligent model has true database attached in every object in PDMS (example: bore, insulation, etc) while primitive don’t.
The PDMS also use hierarchy for both primitive model and intelligence model. It’s divided from site, zone, module of various design (structure, equipment, piping, etc.) trough it subs (substructure, sub equipment, etc). The difference of primitive and intelligent are only in its object database (which a lot, I assure you). From this database, a software can calculate many of it’s implications such as pipe stresses beside the obvious process flow.
Below are samples of Intelligent PDMS:
Below are a few sample of Primitive PDMS and in some of other programs:
The same model in Sketch Up:
Another sample of primitive PDMS:
This is the same model in Solidworks:
