Virtuoso®/ES is composed of a simulation engine capable of performing transient modelling of integrated subsea, topsides and onshore facilities and controls, along with a customizable graphical user interface (GUI). This basic package can be used for engineering studies from front-end engineering through the operating phase of a project. Typical uses include building and validating startup, shutdown, and other operating procedures, validation of control schemes, controller tuning, and performing offline what-if analysis.

The simulation engine includes a comprehensive set of transient models of upstream production and processing equipment including wells, production trees, manifolds, multiphase pipelines, separators, compressors, tanks, and pumps.

Virtuoso/ES has the ability to replicate complete control programming including subsea control (MCS), process control (PCS), and specialized control applications (i.e. anti-surge, load sharing, etc).

The user interface for Virtuoso/ES provides user-friendly, integrated, drag-and-drop trending, user-savable plot collections, scenario and condition save and reload functionalities, and a host of other features tailor-made for engineering analysis.
