Automation in port terminals is no longer limited to greenfield developments; it has become a strategic objective to improve productivity, safety, predictability and advance decarbonisation. However, most terminals worldwide operate as brownfield environments shaped by decades of incremental investments, legacy systems and operational inertia. This makes automation a challenge that must be addressed without interrupting operations or assuming excessive risk.
In these environments, the perception persists that automation requires “all‑or‑nothing” redesigns—a significant barrier when operational continuity is critical. The challenge does not lie in technological availability —the solutions exist— but in having an architecture capable of incorporating new capabilities without compromising system stability.
In this context, the Terminal Industry Committee 4.0 (TIC4.0), which brings together operators, manufacturers and technology providers, addresses this challenge by defining common digital standards. Its premise is clear: without a shared language between equipment, systems and applications, brownfield automation will remain complex and costly. The frameworks and definitions developed by TIC4.0 provide the technical foundations upon which new digital capabilities can be introduced.
Building on these foundations, the article proposes a pathway based on established industrial frameworks such as IEC 62264, which structure automation into layers—planning, execution and control—while remaining compatible with legacy systems. This approach enables modular evolution, orderly incorporation of interoperability, and the progressive adoption of AI, reducing risk and accelerating time‑to‑value without compromising operational continuity.
“Standards are not an alternative to artificial intelligence, but a prerequisite for deploying it effectively within brownfield automation strategies.”
The main inputs and contributions are:
- Brownfield automation is conditioned by decades of technological and operational decisions, with TOS platforms expanded over time, custom integrations, siloed data structures and a corporate culture tied to manual or semi‑manual decision‑making. For this reason, automation cannot be introduced abruptly.
- Terminals achieving the greatest operational and productivity improvements are those that first establish common data models, standardised interfaces and the application of these principles to operational reality—before deploying large‑scale advanced automation or AI‑based optimisation.
- The implicit cultural recipe is to shift to a step‑by‑step logic: adding capabilities layer by layer without disrupting operations, enabling the organisation to absorb the change in its day‑to‑day activities and reducing internal resistance.
- Many “theoretical” operational processes do not match day‑to‑day reality, making automation difficult without first standardising semantics, events and states. This gap is one of the least visible yet most relevant inefficiencies in brownfields.
- The TIC4.0 framework provides a functional decomposition based on IEC 62264, separating planning, execution and control layers. This avoids functional dependencies and supports modular automation.
- TIC4.0 proposes digital semantic standardisation that defines a common language for events, equipment states, work orders and operational conditions, reducing ambiguities that currently hinder the adoption of AI, optimisers or advanced supervision systems.
- The benefits of standardisation include reduced risk, modular scalability, shorter time‑to‑value, gradual cultural transition and the creation of a shared foundation.
- AI’s role as an incremental capability—useful for prediction, optimisation or supervision—depends entirely on interface stability, semantic clarity and data consistency.
- Automation must evolve progressively, never disruptively, avoiding the introduction of new capabilities that could compromise operational continuity.
“The key issue for brownfield terminals is how to move step by step towards higher levels of automation while preserving operational continuity and controlling cost, time and risk.”
