Aged pipes in hydrocarbon and industrial gas transportation systems represent one of the greatest technical challenges in the global energy industry. Thousands of kilometers of pipelines operate beyond their original design life, facing phenomena such as corrosion, mechanical fatigue, and changes in operating conditions.
However, this challenge also opens a strategic opportunity: extending the useful life of these assets through advanced integrity approaches. The energy transition does not necessarily mean replacing all existing Aged pipes infrastructure, but rather adapting it for new uses, such as the transport of hydrogen (H₂) or carbon dioxide (CO₂).
In this context, integrity management becomes a key enabler. Companies like TEAM Inc. have developed comprehensive solutions that allow evaluating, monitoring, and prolonging the safe operation of critical assets, combining advanced inspection, data analysis, and predictive maintenance.
Multidisciplinary engineering in renewable energy
Engineering in renewable energy projects has evolved towards a deeply multidisciplinary approach. It is no longer just about designing a solar or wind farm, but about integrating multiple systems into a complex energy ecosystem.
This approach includes coordination among civil (foundations, structures), mechanical (rotating equipment, thermal systems), electrical (generation, transformation), control (automation), environmental (impact and permits), and grid connection engineering. Each discipline contributes critical variables that must be aligned from the early stages of the project.
The true complexity lies in the interaction between these disciplines. A change in the electrical design can affect the civil layout; a modification in the control system can impact the overall efficiency of the system. Therefore, disciplinary integration is not optional: it is the core of project success.
What does multidisciplinary engineering mean?
Speaking of multidisciplinary engineering in renewables means designing systems, not isolated components. It is a paradigm shift where the focus is no longer sequential but becomes simultaneous and interdependent.
In practical terms, this implies that from the conceptual phase (pre-FEED), all disciplines work on shared models, generally supported by digital tools such as digital twins and BIM platforms. This allows anticipating conflicts before they materialize on-site.
Furthermore, this approach facilitates the overall optimization of the system. For example, in a hybrid solar + storage + grid connection system, optimal sizing does not depend solely on generation, but on the dynamic interaction between all subsystems.
Interface Management: Determining factor in avoiding cost overruns
One of the greatest risks in complex energy projects is poor interface management. Every interaction point between disciplines or contractors represents a potential source of error, delay, or cost overrun.
Interface management seeks to identify, document, and control these interactions. This ranges from physical connections (piping, wiring) to functional integrations (control systems, SCADA).
Effective interface management can significantly reduce rework. In EPC and EPCm projects, where multiple contractors are involved, this discipline is critical to maintaining the technical and contractual coherence of the project.
FEED and EPCm: Decisive moments in the project cycle
A renewable energy project requires different levels of definition throughout its life cycle. The FEED (Front-End Engineering Design) phase is where the technical, economic, and risk foundation of the project is established.
During FEED, key specifications are defined, technologies are selected, and costs are estimated with greater precision. It is the moment where multidisciplinary engineering has the greatest impact, as the decisions made here condition the entire project.
The EPCm (Engineering, Procurement and Construction Management) model, on the other hand, allows for greater flexibility in execution. Instead of a single contractor, the owner maintains greater control, which is especially useful in hybrid projects or those with high technological uncertainty.
Hybrid systems: Redefining design methodology
The integration of hybrid systems—such as solar + wind + storage + hydrogen—is transforming the way energy projects are designed.
These systems require a systemic vision, where the goal is not to maximize the production of one component, but to optimize overall performance. This implies modeling operational scenarios, analyzing demand profiles, and considering grid constraints.
Furthermore, hybrid systems introduce new control and operational challenges. Coordination between multiple energy sources and storage systems requires advanced algorithms and dynamic dispatch strategies.
Grid interconnection: Operational constraints
As the penetration of renewable energies increases, grid interconnection has become one of the main technical and regulatory challenges.
Interconnection studies must evaluate grid capacity, system stability, and the impact of new intermittent sources. This requires close collaboration between electrical engineers, power system specialists, and grid operators.
Moreover, interconnection is no longer a static process. In hybrid systems, export capacity can vary dynamically, demanding more sophisticated and flexible models.
Asset integrity in the energy transition
The transition towards cleaner energy does not eliminate the need for existing infrastructure; it transforms it. Pipelines, for example, are being evaluated to transport new fluids such as hydrogen or CO₂.
This poses new integrity challenges. Hydrogen, for example, can cause embrittlement in certain materials, while CO₂ in supercritical conditions requires specific design and operational considerations.
This is where expertise in asset integrity becomes critical. Companies like TEAM Inc. offer services ranging from advanced inspection to Fitness-for-Service evaluation, enabling a safe and efficient transition.
The role of systems engineering in renewables
Systems engineering provides the methodological framework for managing the complexity of multidisciplinary projects. Its approach is based on defining requirements, managing interfaces, and validating the performance of the system as a whole.
In renewable projects, this translates into better decision traceability, greater risk control, and comprehensive design optimization. The systems engineer acts as the common thread that integrates all disciplines.
Furthermore, it facilitates data-driven decision-making, allowing the evaluation of multiple scenarios and the selection of the best option from a technical and economic perspective.
Decisive event: Pipeline Technology Conference 2026
The debate on pipeline integrity and the energy transition will have a meeting point at the Pipeline Technology Conference 2026, to be held from April 20 to 23 in Berlin, Germany.
This event, recognized as “The Lighthouse of the Pipeline Industry,” will address critical topics such as asset management, anomaly assessment, and hard-to-inspect pipelines. In addition, emerging applications such as hydrogen and CO₂ transport will be discussed.
The conference represents a key platform for sharing best practices, technological innovations, and strategies to extend the useful life of existing infrastructure in the context of the energy transition.
What disciplines define a viable project?
A viable renewable energy project does not depend on a single discipline, but on the effective integration of several:
- Electrical engineering: generation, transformation, and interconnection
- Mechanical engineering: equipment and thermal systems
- Civil engineering: structures and civil works
- Control engineering: automation and operation
- Environmental engineering: permits and impact
- Systems engineering: integration and optimization
The absence or weak integration of any of these disciplines can compromise the project’s viability.
Integration as a competitive advantage
The convergence between asset integrity and multidisciplinary engineering is redefining the energy future. The ability to extend the useful life of existing infrastructure, while integrating new renewable technologies, represents a key competitive advantage.
In this scenario, coordination between disciplines, interface management, and the systemic approach are not just good practices: they are fundamental requirements for success.
The future of energy will not be defined by isolated technologies, but by integrated, resilient, and optimized systems. And in that future, multidisciplinary engineering will be the common language that connects every component of the system.
Conclusions
Aged pipes represent both a challenge and a strategic opportunity in the energy industry, as proper integrity management enables the safe extension of their service life, avoiding costly replacements and maximizing the use of existing infrastructure.
The adaptation of aged pipes for new applications, such as hydrogen or CO₂ transport, requires a multidisciplinary approach that integrates engineering, materials analysis, and risk assessment to ensure reliable performance under more demanding operating conditions.
The integration of advanced technologies, such as smart monitoring, data analytics, and systems engineering methodologies, positions the management of aged pipes as a key factor for an efficient, safe, and sustainable energy transition.
