How one organisation optimised digital twins in upstream design processes

Bently ORME twinIn a whitepaper by the ARC Advisory Group, in collaboration with Bentley Systems, Valentijn de Leeuw, vice-president, March 2021, ARC Advisory Group, has described how one organisation optimised digital twins in upstream design processes

Ensuring the design team and stakeholders work together is crucial at the start on any large capital project. Collaboration is essential when it comes to working with many different groups, partners, subcontractors, and inter-departmental personnel, as they work with multiple information sources and make numerous design changes as part of the review process. Failure in any of these work processes can result in costly mistakes once handover is complete as the project moves into construction - and even more so as it moves into operations. 

This scenario, which had been typical among engineering firms, is one that NOV Inc wished to avoid. 

NOV Inc, a global company headquartered in Houston, Texas, delivers technology-driven solutions to the global energy industry, including solutions supporting digital and smart oilfield initiatives. 

This article examines how NOV overcame the problem of remote collaboration by having a unified view of their federated data from multiple sources provided by PlantSight, the digital twin cloud-based service developed by Bentley Systems and Siemens to support distributed/remote collaborative processes and engineering 3D design and operations.

Solving the problem of remote collaboration  

Previously, NOV used Navisworks to share designs with fabricators or subcontractors, since it was a widely used review application in the oil and gas sector and could accept multiple file formats. One of the main disadvantages of the platform was the inability to track changes and versions across the disciplines. Therefore, identifying which model was the main ‘source of truth’ proved difficult when there was more than one file being used. In addition, NavisWorks uses snapshots of the design files, and keeping this information up to date is impossible. 

NOV overcame these problems by switching to PlantSight, as the models for the project can be securely shared in the cloud with partners and are always kept up to date. PlantSight pulls the latest information in real time from the design tools, and changes are instantly fed back to the originating system, showing a complete audit trail of when a change was made, why, and by whom. Models are protected, and it is possible to control which parts of the project a partner or client can see. 

Solution selection and digitalisation

NOV had scanned the market and did not find any other tools with the same level of openness and flexibility as PlantSight. The capability to integrate the digital twin solution with many other tools increased NOV’s confidence in the software. Already a user of Bentley’s OpenPlant design application, NOV could seamlessly integrate their design review work processes between OpenPlant and PlantSight to take advantage of real-time change management, issue resolution, and clash detection features. 

One additional hurdle was convincing management to switch to PlantSight, as they were not involved with projects on a day-to-day basis. However, they realised and understood that it would be inefficient to create a digital twin using the old method of pulling together a review model on a single system with everyone, then commenting on the overall design during a review meeting. Management were convinced of the digital twin solution due to the transformation they saw with the potential for savings and the significant benefits of remote collaboration and reviews in real time. This proved advantageous when the COVID-19 pandemic struck just after the start of the project, as PlantSight could help all project team members collaborate from home while working simultaneously on shared design information. 

Keeping the project on track 

Working alongside Bentley, NOV’s CAD manager and some key personnel worked on testing iterated versions of the solution to achieve acceptable new digital work processes. The project was able to remain close to the original schedule plan of about six months for preparation and acceptance of the new ways of working for their teams. 

While thinking big about digital transformation and digital twins, NOV decided it was best to first prove small. In controlled phases, NOV started their PlantSight implementation with a small group from the 3D layout department and associated personnel making the transition easier to control. Process design and schematics was the next phase, which created further ease of use for piping designers as more information from the upstream design process was made available to them. 

Cloud-based accessibility and security

When NOV went live with PlantSight, they moved from server-based to cloud-based software. The transition removed the limitations of specific design files on local servers used by different disciplines working independently, while also eliminating any inconsistencies and rework. With PlantSight, personnel can now work simultaneously on a single, large design, and are immediately notified when clashes are detected and other issues are highlighted. Since PlantSight is cloud based, personnel can access files remotely, where space, security and scalability is never a problem. 

With the PlantSight digital twin service, NOV keeps information in one place, controls it in a single environment, keeps it consistently up to date, and makes all data sources accessible. For example, 3D design information, the attributes of piping specifications, and installation notes for the piping are all visible and manageable from a web browser. As well as being able to work faster, collaborate more effectively, and make design changes wherever they are, NOV personnel improved productivity by reducing interruptions and shortening project waiting times. With two dedicated resource personnel, NOV supports 100 engineers on projects that typically have 20 contributors who don’t require much assistance or support.

The future outlook

Cloud-based digital twins can quickly demonstrate the benefits of combining engineering, design, build, construction, operations and maintenance data, including 3D representations and quality-related data. NOV have already gained the benefits of remote and collaborative design reviews and qualification, overcoming common pitfalls such as unreliable information, manual processes, and an unclear line of sight across the design team. They have been able to improve their designs and resolve any issues and potential clashes early in the design phase, so they don’t become expensive problems in the construction or operational phase.

Moving forward, the digital twins in PlantSight are inspiring new ideas for products and processes within NOV. They can modify designs to include remote equipment, and operations can be monitored by feeding live data directly to the models for a complete picture of performance.
