At the start of any large capital project, ensuring the design team and stakeholders work together is crucial. Collaboration is key when it comes to working with many different groups, partners, subcontractors and inter-departmental personnel, as they work with multiple data sources, numerous design changes and reviews. Failure in any of these work processes can result in costly errors or mistakes as the project moves into construction - and even more so as it moves into operations. Lengthy project delays and subsequent operational downtime is expensive. This scenario, which had been typical among engineering firms, is one that NOV Inc. wished to avoid.

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

NOV Inc., a global company headquartered in Houston delivers technology-driven solutions to the global energy industry, including solutions supporting digital and smart oilfield initiatives. The NOV Wellstream Processing division supplies equipment and solutions for all the activities NOV performs when separating and treating oil and gas as part of an upstream production facility.

The collaboration challenge

One of the main challenges for NOV was being able to bring the many discipline-specific models and files together to enable the design team to share information with all stakeholders around a single plant model and resolve issues. 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. Furthermore, sharing files can lead to security lapses since other parties could potentially extract information from them.

NOV overcame these challenges by switching to PlantSight, as the models for the project can be securely shared with partners and are always 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 digitalization

As NOV were already familiar with Bentley applications; PlantSight came at a relatively low cost and did not incur any additional training costs. With PlantSight, the company could build on its know-how and the transition caused minimal disruption. NOV had scanned the market and did not find any other tools with the same level of openness as PlantSight. The capability to integrate the digital twin service with many other tools increased NOV's confidence in the software. Already a user of Bentley's OpenPlant design application, NOV could seamlessly integrate its design review work processes between OpenPlant and PlantSight to take advantage of real-time change management, issue resolution and clash detection features.

Convincing management to switch to PlantSight was challenging, as they were not involved with projects on a day-to-day basis. However, they realized and understood 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 was convinced of the digital twin solution due to the transformation they saw with the potential for savings and the significant benefits of real-time reviews.

When the COVID-19 pandemic struck just after the start of the project, the case became even more compelling, as PlantSight could help all project team members collaborate from home while working simultaneously on shared design information.

Implementation

NOV was an early adopter of PlantSight, as they used it before it was officially released in 2019. 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 its 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. Previously, the piping designers had to enter a lot of information manually to start their work. Now, they could easily reference the existing layout information.

Going digital

The company went live with PlantSight, moving from server-based to cloud-based software and removing the limitations of specific design files on local servers used by different disciplines working independently. Inconsistencies and rework were eliminated. With PlantSight, personnel can now work simultaneously on a single, large design and are immediately notified when clashes are detected, and other issues are noted. Since PlantSight is cloud-based, personnel can access files remotely, where space, security and scalability are never a problem.

With the PlantSight digital twin service, NOV keeps information in one place, controls it in a single environment and keeps it consistently up to date. Different data sources are accessible within PlantSight. For example, 3D design information, the attributes of piping specifications and installation notes for the piping are visible and manageable from a web browser.

Previously, if a piping manager wanted a piping layout report, they had to involve a piping designer. Now, the piping manager can use self-service dashboards and reports directly. As well as being able to work faster, collaborate more effectively and make design changes wherever they are, NOV 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 need much assistance or support.

Outlook

The overall transition from NavisWorks to PlantSight was very smooth. After receiving a two-hour training course and participating in hands-on exercises, they began working on their projects faster with PlantSight. Moving forward, the digital twins in PlantSight are inspiring new ideas for products and processes. NOV can modify designs to include remote equipment operation, and operations can be monitored by feeding live data to the models.

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 has 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.
