Backbone of plant data
Equinor ASA, formerly Statoil, is one of the world's largest offshore operators, and also maintains refineries and wind farms. The company is undergoing a transformation process whereby the traditional document-oriented lifecycle information on the plants is becoming highly digital, centrally managed data. It is much easier to keep up-to-date, and maintenance is greatly facilitated. Therefore, the Norwegian offshore expert decided to digitize and maintain his plants with the data-centred, cooperative platform Engineering Base (EB).
"We're very proud that Engineering Base provides the backbone for the data relating to Equinor's plants and their maintenance. It was probably not entirely by chance that they named the EB project 'Spine'," said Uwe Vogt, Executive Officer at Aucotec. “The fact that Equinor is also one of the major new clients that we were able to impress with this is an outstanding endorsement of our team," stressed Vogt. The system covers all core disciplines of process engineering from FEED via basic and detailed engineering, DCS configuration and cause & effect support to maintenance.
Maintenance made efficient
Equinor is starting to work with EB on the new Johan Sverdrup oil rig project, which began oil production in January 2020. It opens a huge oil field approximately 160 km outside Stavanger, whose capacity is expected to last for about 50 years. The plant, consisting of several drilling platforms, will also have to work as efficiently as possible for a correspondingly long period of time and will always have to have up-to-date documentation.
"Equinor expects a significant simplification and thus an acceleration of maintenance work. Changes and collaboration with many subcontractors, whether in the design area or in operation, are much easier to implement and are more consistent with this unique master engineering database," explained the Aucotec Executive Officer Vogt. For this purpose, more than 350,000 Johan Sverdrup documents are being migrated to EB and digitally processed there.
The complete digital twin
Since all disciplines are covered by EB's object-oriented plant model, changes have only to be centrally entered once. Each representation of the modified object is automatically updated. "This is how EB contains the complete digital twin with all its logic, and not just a sub-discipline," said Vogt. "Not only EB, but also the whole Aucotec team won them over," he added.
