Common Challenges in P&ID Creation

As it is mentioned earlier that drafting the piping and instrumentation diagrams for the project is not bereft of roadblocks. One can face these challenges during Plant Design Engineering. Here are the details of the challenges.

Challenge 1: Inconsistencies in Process Data

One of the biggest challenges the engineers face during the Piping and Instrumentation Diagrams drafting is the presence of inconsistencies and irregularities in data. These diagrams serve as the blueprints for the plants. Given its importance, any inaccuracy in the data can have a dangerous impact on the viability of P&ID. There can be multiple sources of irregularities. The manual handling of data can also obstruct the process of drafting. In the same manner, inconsistent use of symbols & tags, and mislabeling of equipment further complicate the data. Moreover, the absence of standard data formats can also give rise to errors and hamper the progress of the design process.

Solution

So, before initiating the drafting process, engineers must invest some time in gathering detailed and error-free process information to avoid any kind of discrepancy throughout the procedure. In this regard, AutoCAD 3D Toolset can be handy to address these issues. It comes with libraries of industry-proven symbols for piping, instrumentation, and equipment. Moreover, it allows you to understand the rules to check the accuracy of P&IDs.. Through tagging and annotation, you can also standardize the tags, thereby eliminating the risk of errors. These annotations are often linked to data so they can reflect the correct information.

Challenge 2: Complex and Time-Consuming Drafting

Another challenge that hampers the creation of P&IDs is the complexity of design and time-consuming drafting based on the components. We acknowledge that these diagrams represent complex systems with precise detail for equipment, piping, and instrumentation. For better accuracy, these diagrams must precisely show the connections between different components, such as pipes, valves, sensors, and control devices based on the diagrams. Managing these complex details without any significant and advanced tools can lead to errors, making it impossible to ensure the correct representation of all the related components.

Solution

AutoCAD Plant 3D offers specialized tools designed to manage complex diagrams easily. Its intuitive and seamless interface allows users to create and modify P&IDs with precision. The software delivers a comprehensive library of industry-standard symbols and components, ensuring that all elements are accurately represented without any confusion. Additionally, through specification-driven design, you can explain the pipe specifications by adhering to the industry standards. The software also facilitates automatic connection of pipes and intelligent routing based on the well-defined paths. This property can reduce the manual efforts in drafting and make the creation easy and without any difficulty.

Challenge 3: Data Management as a Daunting Task

When it comes to Industrial projects, it is hard to ignore interconnected components. While understanding its specifications, data management becomes a difficult task due to outdated software. In this regard, clearly showing their relationships without cluttering and damaging the essence of the diagram is a common challenge that experts face while dealing with large-scale projects. Moreover, inability to keep up with the technologies and frequent changes can further exacerbate the challenge.

Solutions

In the AutoCAD Plant 3D Toolset, data can be properly managed by storing it in a SQL database. Any updates to one part of the P&ID ( tag number, specification) are reflected across all relevant components and documentation. By managing the data effectively and layering and labeling it correctly, one can avoid this challenge smartly.

Challenge 4: Balancing Standardization with Customization

During the design process, one must ensure that P&IDs comply with industry standards and regulations for better safety measures and efficiency. Any kind of non-compliance can cause financial losses and costly rework, indefinite project delays, and even increase safety issues. Different industries and regions have specific standards for P&IDs, such as ISA and ISO. Therefore, based on unique project requirements, it becomes difficult to balance the customized options with standard protocols, limiting flexibility or missing client-specific requirements.

Solution

AutoCAD Plant 3D also the process of balancing the standardization with personalization by supporting a wide range of proven industry standards, and allows users to create P&IDs that live up to the expectations of regulatory approvals.  The software offers CAD Customization templates and the latest symbol libraries that adhere to various compliant standards and codes, ensuring the diagrams fulfill the required specifications. AutoCAD also allows users to customize these templates tailored to organizational standards. Furthermore, AutoCAD Plant 3D allows the enforcement of P&ID templates to reduce the chances of mishap.

Challenge 5: Tangible Disconnection between P&ID and Plant 3D Model

Another common challenge in P&ID drafting is the tangible disconnect between the 2D P&ID drawings and the 3D plant model. 2D drawings show 3D objects on a flat plane. This natural limitation makes it highly challenging to understand the plan layout. Engineers can make mistakes when they translate 2D drawings into a 3D reality, leading to errors that are often not discovered until late in the design process.

Solution

This toolset has the potential to address this issue by offering an integrated workflow between the P&ID and 3D plant model. Instead of drawing 2D symbols, the 3D toolset allows users to utilize intelligent 3D models of equipment and piping. When a P&ID is developed in the Plant 3D tool, the components are automatically generated in the 3D form based on P&ID data. This smooth integration not only generates the components but also allows for the automatic generation of reports and documents such as equipment lists, piping specifications, and valve schedules. This eliminates the disconnection and delivers accurate pictures based on data.

Challenge 6: Keeping Up with Frequent Changes in the Design Process

During the design phase, frequent changes occur throughout the process. These changes range from style modification, design upgrades, pipe size, pipe design, and changes in the layout of the process. Inability to keep up with the frequent changes can cause severe challenges.

Solution

Here is the solution. During the design process, the effective use of digital tools such as AutoCAD Plant 3D and SmartPlant can reduce the chance of excessive modifications. The advanced software enables the engineers to monitor document revisions and manage these upgrades at an early stage.

Challenge 7: Limited Reporting and Documentation

Comprehensive documentation and reporting are essential for project management and operational efficiency. Generating detailed reports and maintaining comprehensive documentation manually can be tiring. By reporting the process manually, not only damage the credibility but also derails the process.

Solution

By using AutoCAD Plant 3D, the users can streamline documentation and reporting and reduce the chances of limited reports. The software can generate a wide range of reports, including equipment lists, line lists, and instrument indexes, accurately based on the data of P&ID.
