Offset have vast experience in the Oil and Gas industry, with both off-shore and on-shore projects successfully carried out on numerous occasions.
Here is a selection of some of the offshore projects. Click the images for an enlarged view of the examples shown.
Three platforms on this large complex were surveyed to establish a base line as built.
The complete 3D model was produced using Magan and was supplied cross referenced with plant P&IDs to PDMS format.

Offset Services have been involved with the production of asbuilt information for several offshore installations for Shell Brunei. Here are examples of 3D as-builts of Fairley Oil Field installations: Fairley 1 and 3.
All these models are tag referenced using P&IDs supplied by Shell and delivered as an intelligent 3D PDMS model.
This survey, undertaken in the South China Sea - offshore Brunei - was completed in 2 site days by a team of 2 engineers. 350 photopairs were taken of 17 wellheads, surrounding structure and piping, with a total of 500 surveyed photogrammetric targets.
This data was supplied on CD in visual database format together with MaganJr software ready for 3D coordinate retrieval by plant operators upon leaving the platform.
The complete 3D model took 15 days to produce, using Magan, and was supplied cross-referenced with plant P&IDs to PDMS format. This PDMS model was also be used to test and qualify the AVEVA's new Vantage Enterprise NET product.
Upgrading the existing diesel powered pumps to gas turbine powered pumps necessitated extensive, accurate, as-built data of this installation.
A team of 2 engineers spent 11 days offshore collecting survey and photographic data of 4 modules and the jacket cap.
The 3D model took 60 office based man days to produce using Magan and was cross referenced with existing P&IDs, delivered in PDMS format.
'The largest ever expansion project to an existing platform carried out by Shell Malaysia was successfully completed on 20th September 2002 with several major heavy lifts executed safely onto the M1 platform. A total of 1300 metric tons of facilities were lifted and assembled on platform. The key success factors leading to the safe completion of this very risky installation included the application of 3-D modeling and photogrammetry technology ensuring the existing as-built conditions of the platform were captured, this resulted in a timely installation of the major decks, coolers and vessels resulting in optimal utilization of expensive resources, namely Cat 1 barge' - Shell internal newsletter - read the full article here.
