PDMS is a 3D piping design software used for designing oil/gas platforms, refineries, chemical plants, and nuclear power plants. It allows seeing an actual 3D model of the design. Using PDMS can reduce project costs by 10-30% through time and material savings. It contains modules for piping, equipment, structures, HVAC, and other design elements. Companies use PDMS for its accuracy, clash detection capabilities, and ability to generate reports and drawings from the model.
Pdms overview
- 1. Overview of PDMS Raghunathan Janarthanan| Piping Designer
- 2. 3D piping designing software plant design management system (PDMS), overview of PDMS, its uses, its commands.This is one of the best software for designing the big plants with more accuracy.There are different modules in the pdms for designing of the plants. Overview of PDMS These day lots of 3D piping designing software are available in the market. Every software has own limitations and uses.The engineering designing consultancy companies are selecting this software as per their business model, as per requirement of the project and the client demands for particular software in which they want the project. Right now 3D piping designs software are available in the market are Plant design management system (PDMS), Plant Design System (PDS), Cad Pipe, Cad works, and spid3D etc. In these software's I shall you let you know regarding plant design management system (PDMS).
- 3. Plant design management system (PDMS) is used for 3D designing of the oil and gas offshore platforms, refineries, chemical plants and nuclear power plants.The purpose of using that software is that we can see the actual model of offshore platform, refineries etc which is going to build actually in the site. With the use of the 3D software companies can reduce overall costing of the project from 10% to 30% in the form of time saving of the project, material saving of the object. Big engineering procurement and construction companies likeTechnip, Flou, Pertofac, Sumsung heavy industry, Worley person, Aker solutions many more company are using these 3D software like pdms and pds.These software are used globally in their business operations. Now every MNC company has their offices in different part of the world. So while designing of these platforms, refineries, and chemical plants every office has to contribute their role on that project as per their specialty. In PDMS work can we done globally. It means if design office at London did some work on that project.The other employees of Mumbai office can see that work in the model online and work accordingly. PDMS software is produce by Aviva industries. PMDS is best 3D designing software.We can design the entire plant in the PDMS.To use the PDMS software by any company they have to buy the numbers of license as per their requirements.
- 4. PDMS contains 9 modules on which designing can be done in the model Piping modeling Equipment modeling Structure module HVAC Design Hanger and supports or MDS Cabling System Cable trays Design temples Room design
- 5. Advantages of PDMS 1. To see the actual model of the plant in the software with exact dimensions. 2.To reduce the material from 10% to 30% from the manual calculations of the material of the project. 3.We can save time while designing the project in pdms. Designing project in 2d likeAutoCAD taking much more time as compared to pdms. 4. In pdms we check the piping clashes of the piping, equipment and other inter disciplines. 5. Designing is of piping is more accurate. Because we can see all space around the plant.
- 6. 6.Very less chance of rework, if the designing is done on the pdms.This helps us to save fabrication time on the yard. 7.The accuracy is more in pdms as compared to other 2D software 8. Pdms can generate the material take off report of each every component in the pdms, which is not possible in 2d software. From the material take off report we can get exact quantities of material which are going to use in the plant for fabrication purpose.We can order that material as the material take off reports. 9. From pdms we can run isometric drawing of the piping for fabrication purpose automatically. In AutoCAD isometric drawings are taking too much time.
- 7. 10. Modification of any pipe, equipment or structure can be done easy as compared to other software. 11. Pdms is user friendly with other software like Ceaser II for stress calculations andWith AutoCAD to import the data from pdms to these seawares. 12.We can design supports for piping in the hanger and supports module. Pdms is commands based software.While operating the software we required some command to use the software.

- 9. These are the few commands which are using in the PDMS piping design module Axes at CE= to check the axes of component like North, South, East, West direction Q axes at ph= to check the head of the branch of the pipe. Q axes at pt= to check the tail of the branch of the pipe. Q Hstu= to show the branch head tube attribute Q Lstu= to show the branch tail tube attribute Q Hbore= to check the arrive bore or diameter of the component QTbore= to check the leave bore or diameter of the component Q Spre= to check the specification of the particular component Q pspec= to check material class of the pipe.
- 10. New elbow choo all= to create new elbow through command line New tee choo all= to create new tee through command line New gasket choo all= to create new gasket through command line New flange choo all= to create new flange through command line New olet choo all= to create new olet through command line Unclaim all= to remove claim the by user so other user can work in that pipe, equipment, member,structure. Getwork= to refresh the design model. After get work all the change done any user will show in the model. Axes at hpos=To check the branch head axes Axes at tpos=To check the branch tail axes
- 11. Q ltle= to check the length of the spool between the two component Conn ph to fir member= to connect the branch head to first member of the next branch by common line Conn pt to fir member= to connect the branch tail to last member of the next branch by common line Q ori = to check the orientation of the component Dist= to give the distance between two component Clea= to give the spool length between the two component Conn= connect to the member Fconn= to component forcefully Q styp= to check the component selection type Q dtxr= to check the detail text description of the component
- 12. Dir tow next= to connect the next member by direction Q ref= to check the reference Add all the pipe within vol ce 500= all pipes to added in the area 500 around the selected component. Incl= to include the component from one branch to other branch Ori and p3 is up= to orientate the point 3 of the tee in up direction Own= navigate the owner of component Q angle= to check the angle of the component Q atle= to check the length of the first tube of the branch Attype ccnn= comment attachment without dimensions Attype cccc= comment attachment with dimensions Attype xxxx= to set the attachment for isometric break up Ch ce= to check the data inconsistency Dir tow next elb= to align the elbow with next elbow
- 13. Dir tow id@= to align the elbow by using mouse click on the component Q hcon= to check head connection attached with which branch Q tcon= to check tail connection attached with which branch Q ispec= to check the insulation of pipe Ispec nulref= to remove the insulation of the pipe Mtoc dotd= to appear the component in doted in the isometric Mtoc off= to remove the material off the component.With this command material of the component will not appear in isometric Nex conn= connect to next component Nex thro ce= align the next component in same direction Q p3 = to check the p3 point of the component
- 14. Q pa= to check arrive point Q pl= to check the leave point Attype flow= to create the flow direction attachment These are the few commands which are using in the PDMS equipment design module.
