Highly complex plants are a characteristic feature of the oil and gas industry. Extraction plants, refineries and petrochemical plants demand reliability and safety of the highest standard. This makes high-quality data all the more important – both for the entire planning process and throughout the plant's life. Engineering Base was created for the express purpose of developing a complete and consistent digital twin of a plant through interdisciplinary cooperation. It always shows the current status of all assets – for the development team, the project manager, the operator and the service specialists.
