Digital Twin in Pre-Engineering, Optimizing CapEx Feasibility

12 December 2025By

CapEx investments in the Energy and Oil & Gas sectors are high-risk, and the Feasibility Study is the phase that determines 70% of the lifecycle costs. To transform uncertainty into certainty, ST2 Srl integrates the Digital Twin in Pre-Engineering.

We are not just talking about 3D modeling, but a sophisticated behavioral and operational simulation that allows us to virtually “test” the plant. In this way, we address engineering criticalities when the cost of modification is virtually zero.

The ST2 Methodology: Testing the Impossible

Our multidisciplinary methodology creates a dynamic model (Digital Twin) that simulates real-time interactions between systems. This allows us to apply predictive analysis in the most critical areas:

  • Electrical Loads: Optimizing the sizing of transformers and cables, avoiding over-specification, and testing grid stability under extreme conditions.
  • Process Flows: Simulating complex operational scenarios and identifying hydraulic or thermodynamic bottlenecks that would delay commissioning.
  • Ergonomics and Maintenance: Validating layouts for access, safety, and operability—essential for reducing future operating costs (TCO).

Strategic and Financial Benefits

Adopting a Digital Twin in Pre-Engineering translates into direct financial benefits for our clients:

  1. Reduced Redesign Risk: We identify and resolve inconsistencies between disciplines (electrical, instrumental, process) before they become costly errors on the construction site.
  2. Increased CapEx Accuracy: We provide more reliable and detailed cost estimates thanks to precise equipment sizing.
  3. TCO (Total Cost of Ownership) Optimization: A plant optimized from the start operates with higher energy efficiency and requires less complex maintenance over time.

Choose ST2 for Digital Twin in Pre-Engineering

In a market that admits no waste, choosing predictive simulation is a strategic decision. ST2 Srl transforms your project idea into a virtual, tested operational model. Choose the Digital Twin in Pre-Engineering for lasting success and a TCO under control from the very beginning.

Total Cost of Ownership (TCO): The Key to Winning Industrial Tenders

10 October 2025By

In the Oil & Gas and Energy industries, the era when tenders were won solely by offering the lowest list price is over. Today, clients seek partners who do not just deliver a plant, but who guarantee the efficiency and sustainability of operations throughout the entire asset lifecycle. The metric that has revolutionized this paradigm is the Total Cost of Ownership (TCO).

Understanding and demonstrating the ability to reduce the Total Cost of Ownership (TCO) is the secret weapon for securing strategic contracts. It is no longer just about how much it costs to build, but how much it will cost to manage the plant over the next 20 years.

Beyond the Initial Price: Defining Industrial TCO

The Total Cost of Ownership (TCO) is the sum of all costs incurred for an asset, from purchase to decommissioning. For an electrical and instrumental plant, TCO consists of four main components:

  1. Initial Cost (CapEx): Engineering, procurement, and installation.
  2. Operating Costs (OpEx): Energy consumption and personnel.
  3. Maintenance Costs: Repairs, spare parts, and downtime.
  4. Risk Costs: Accidents and regulatory non-compliance.

In the Energy and Oil & Gas sectors, the real economic impact lies in the long term: one hour of plant downtime can cost hundreds of thousands of dollars. Therefore, a design aimed at minimizing TCO is a superior value proposition compared to a simple saving on component purchases.

Strategic Engineering Reduces TCO from the Design Phase

ST2’s expertise lies in making electrical and instrumental design an active driver in reducing the Total Cost of Ownership (TCO).

1. Electrical Optimization for Energy Efficiency

Technical choices made during the study phase have repercussions on energy consumption. Through multidisciplinary engineering, we select high-efficiency components, such as Variable Frequency Drives (VFDs) and premium efficiency motors, which significantly reduce long-term operating costs. These interventions, while potentially increasing the initial cost slightly, guarantee a rapid ROI and a significantly lower TCO.

2. Instrumentation for Reliability

Instrumentation is the backbone of process control. We choose only robust, long-lasting measuring instruments (pressure, temperature, flow sensors) that require less frequent calibration and maintenance. Fewer interventions = lower maintenance costs and, above all, less risk of failure and unexpected interruptions.

Automation and Predictivity: The Heart of Optimized TCO

The real revolution in reducing Total Cost of Ownership (TCO) comes from the integration of advanced automation systems:

  • Predictive Maintenance: Integrating smart sensors and SCADA/PLC systems from the design phase enables predictive maintenance. This eliminates costly surprise breakdowns—the number one enemy of TCO—transforming emergency repairs into planned, cost-effective interventions.
  • Risk Mitigation: Control systems and instrumentation designed for maximum safety reduce operational risks and the insurance costs associated with potential accidents.

By presenting a bid that not only lists material costs but also quantifies expected savings in terms of energy and maintenance through these automation solutions, we provide the client with a complete and winning financial perspective.

Conclusion

Today, Total Cost of Ownership (TCO) is the language of excellence. Companies that, like ST2, can translate their engineering and automation expertise into lower operational risk and higher long-term efficiency are destined not only to win tenders but to become strategic partners for the future of energy.
