Plant owners need easy access to accurate, up to date, engineering information and they need tools that make it simple to keep that engineering data up-to-date over the lifecycle of the plant, reflecting changes due to routine maintenance, turnaround, or large-scale revamp projects. It takes too much time and effort to gather and verify the information they need to make decisions effectively, and for older plants that do not have 3-D models, there is simply no visual way to verify and check information easily.
