1) Offshore platform operating in water approximately 160m deep processing around 350 MMcf/d of gas and designed around 2006 with 21 pipe classes and around 1000 isometrics converted including all structural steel, cable tray, mechanical and electrical equipment items and pipe supports. The project was originally designed using PDS and converted to PDMS 12.1 in around 4 weeks so additional design work could be implemented in PDMS 12.1 which was the clients preferred 3D CAD software.
2) Onshore LNG plant processing 3.7 Mtpa of gas designed in 2003 where the PDS 3D model archive wasn’t originally handed over to the owner so no maintenance or new design had been incorporated into a coherent 3D CAD package or benefitted from the initial PDS 3D design. The asset owner was able to request the PDS archive from the original design contractor and we were able to convert the plant to E3D within 4 weeks which contained 38 pipe classes and around 8000 isometrics. The asset owner separately commissioned a full plant wide 3D laser scan which could be overlaid on the converted E3D design to instantly and accurately capture all as building and enhancements that had occurred over 16 years. Benefitting from the intelligent data and tag conversion from the original PDS design, designers can now easily search and relate all visual 3D data to P&ID’s and other plant drawings and documents with millimetre accuracy.
3) Onshore PDS designed MEG plant sub-area which was part of a larger refining complex which had generally been designed in PDMS 12.1 over many years by many design contractors. The MEG plant had around 57 pipe classes and 6000 isometrics converted from PDS to PDMS 12.1 within 4 weeks. A second sub-area of the plant only had a PDMS design review model (RVM file) available to the client after original design/construction and we used this review model to convert back to intelligently tagged EQUI PDMS 12.1 parametric shapes and polyhedron objects with a hierarchy replicating the design review data. This enabled the asset owner to have their complete plant in a single PDMS 12.1 3D design tool and be able to search for any tags in the plant such as equipment, instruments, process line numbers, special piping items, pipe supports, cable runs, electrical junction boxes, etc.
4) Onshore Gas to Liquid Plant which was only available to the client as an Intergraph PDS Design Review (Microstation DGN/PRP and DRV) file set. This was converted to a PDMS 12.1 intelligently tagged model in one week which could be efficiently viewed and searched in PDMS and accurately represented the hand over design review model. While no isometrics can be run (as the pipe classes/catalogue and PIPE isometrics are not available) the designer can still select piping as an EQUI item which represents the isometric number and SUBE sub-elements represent the fittings and piping making up the isometric components with part number and descriptions available. This enables a designer to generate an MTO if required or tie-in new design with the converted design review model accurately in PDMS. In these conversions all structural steel is converted to catalogue and steel spec SPREFs which can continue to be used for new steel work design. Any intelligently tagged information available in the PDS Design Review (DRV) files can be converted into PDMS (or E3D) UDA data to enhance the conversion to customer requirements.
5) Onshore LNG plant producing 8.9 Mtpa plus domestic gas was designed using SP3D in 2014 and the client preferred all 3D assets be available in PDMS 12.1 to work cohesively with their other 3D assets including existing maintenance, operations and documentation software. We worked with the client to convert all 49500 isometrics using 77 pipe classes to PDMS 12.1 as well as all other civil, structural, mechanical, electrical and instrument disciplines with system number, work pack, tagging and descriptive data so all future design could be progressed in PDMS 12.1 (or E3D in the future). This conversion process was achieved over four months, matching the clients original schedule and budget scope.
6) Onshore refinery originally designed in PDS during a major cracker upgrade in 1997 and then maintained in PDS by the client themselves for over 23 years to incorporate all areas of the plant in their 3D model. The client has since made the decision to shut down and demolish the refinery and maintain only a tank farm for fuel storage and blending on site. The client wanted to maintain the valuable 3D model but no longer wanted the expense of PDS as it is slowly becoming redundant so we converted only tank farm relevant PDS models selected by the client to E3D, taking only four weeks. The conversion included all relevant equipment, structural, civil, electrical and instrument models including 2500 piping isometrics, 18 pipe classes and associated pipe supports.
These are just a few examples – many more conversions to come…….
How can you leverage off your historical 3D model archives and design review models for future design, operations and maintenance benefits in PDMS/E3D?
