AMPA09 Complex , SHELL, Brunei
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.

Fairley Oilfield, SHELL, Brunei
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.
Champion 7, Brunei
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 will also be used to test and qualify the AVEVA's new Vantage Enterprise NET product.
M1 Expansion Phase 1 - South China Sea - Malaysia
Offset Services Ltd carried out photogrammetric survey of this offshore facility including all pipe line tie in positions and structural mounting points. Subsequent surveys at various fabrication yards resulted in changes to manufactured panels to ensure correct fit-up to offshore geometry during installation. The next phase of photogrammetry involved pipe route verification of new spools linking existing offshore pipework and prefabricated spools situated on the new panels. The application of photogrammetry on this project was estimated to have saved US$ 2 million.
'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.
Esso Irong Barat - Malaysia
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.
