How does automated yard planning software account for hazardous cargo segregation?

Automated yard planning software accounts for hazardous cargo segregation by integrating regulatory frameworks, applying rule-based algorithms, and performing real-time constraint checking during container slot allocation. These systems incorporate IMDG segregation tables to enforce distance and separation requirements between incompatible dangerous goods classes, automatically flagging violations before they occur. This ensures terminals maintain regulatory compliance whilst optimising operational efficiency across thousands of container movements.

What is hazardous cargo segregation and why does it matter at terminals?

Hazardous cargo segregation is the practice of separating dangerous goods according to their chemical properties and incompatibility classes. The International Maritime Dangerous Goods Code establishes classification systems that identify which cargo types must be kept apart to prevent chemical reactions, fires, or explosions. Terminal operators managing thousands of containers must ensure these segregation requirements are met continuously across all yard operations.

The regulatory framework mandates specific separation distances between incompatible classes. Common segregation requirements include:

Cargo Type Must Be Separated From Risk If Combined
Flammable liquids Oxidising agents Fire or explosion
Toxic substances Foodstuffs Contamination
Corrosives Flammable materials Chemical reaction

Improper segregation creates serious safety risks, including uncontrolled chemical reactions that can lead to catastrophic incidents affecting personnel, infrastructure, and surrounding communities.

This requirement adds substantial operational complexity to terminal planning. Operators must consider segregation constraints alongside other priorities such as vessel loading sequences, equipment utilisation, and gate throughput. Manual management of these competing demands becomes increasingly difficult as terminal volumes grow, making automated solutions necessary for maintaining both safety compliance and operational performance.

How does automated yard planning software actually handle segregation requirements?

Automated systems enforce segregation rules through integrated IMDG segregation tables that define compatibility relationships between all dangerous goods classes. When processing hazardous cargo declarations, the software assigns compatibility scores to each container based on its UN number and class designation. These scores determine which storage locations satisfy both regulatory separation requirements and operational objectives.

The software applies distance and separation rules during slot allocation by calculating spatial relationships between containers. Rule-based algorithms evaluate:

  • Horizontal separation distances between incompatible cargo classes
  • Vertical stacking restrictions for dangerous goods
  • Special requirements for specific cargo types (refrigeration, ventilation, isolation)
  • Proximity limitations to terminal boundaries and populated areas

The system automatically flags potential violations before containers are positioned, preventing non-compliant configurations from occurring.

Real-time constraint checking ensures segregation compliance throughout all yard movements. As containers arrive, depart, or are relocated, the system continuously validates that all existing and planned positions meet segregation standards. This dynamic assessment allows terminals to maintain compliance even as yard configurations change constantly throughout operational shifts.

These systems balance segregation requirements with other operational priorities through weighted optimisation algorithms. Whilst safety compliance remains non-negotiable, the software seeks solutions that also support efficient vessel loading sequences, minimise equipment travel distances, and maintain target throughput levels. This multi-objective approach ensures container terminal automation delivers both regulatory adherence and operational performance.

What challenges do terminals face when automating hazardous cargo planning?

Data quality represents the most significant challenge in automated segregation systems. Incomplete or incorrect cargo declarations prevent software from accurately assessing compatibility and applying appropriate separation rules. When shippers provide inaccurate UN numbers or omit hazardous classifications entirely, automated systems cannot enforce proper segregation, requiring manual intervention that undermines automation benefits.

The complexity of multi-level segregation rules creates implementation difficulties. Key complexity factors include:

Challenge Area Complexity Factor Impact on Automation
Rule configuration Multiple simultaneous requirements (horizontal, vertical, distance-based) Requires sophisticated algorithm design
Cargo combinations Different treatment for different class pairings Increases system configuration complexity
Regulatory exceptions Numerous special cases and exemptions Demands flexible rule engine architecture

Integration with existing terminal operating systems poses technical challenges. Hazardous cargo information must flow seamlessly between cargo documentation systems, yard management platforms, and equipment control systems. Poor integration creates information gaps that force operators to maintain parallel manual processes, reducing the reliability and efficiency gains that terminal automation should deliver.

Training personnel to trust and verify automated decisions requires careful change management. Operations teams must understand how automated systems make segregation decisions whilst maintaining the ability to identify and handle exceptions appropriately. Balancing safety compliance with operational throughput demands ongoing attention, as overly conservative segregation rules can reduce yard capacity whilst insufficient separation creates unacceptable risks. These industry challenges require comprehensive solutions that address both technical and operational dimensions.

How we help terminals implement safe automated yard planning

Portwise Consultancy supports terminals in implementing automated yard planning systems that properly handle hazardous cargo segregation through a structured approach addressing both technical configuration and operational readiness. Our methodology ensures segregation requirements are met without compromising the operational performance that makes automation worthwhile.

Our implementation services include:

  • Segregation rule configuration and validation – We configure IMDG segregation tables within your terminal operating system, validating that all compatibility rules, distance requirements, and stacking restrictions are correctly implemented for your specific operational context.
  • Simulation testing of segregation scenarios – Using advanced simulation models, we test segregation compliance under realistic operational conditions before go-live, identifying potential issues and optimising rule sets to balance safety with throughput requirements.
  • Integration with cargo documentation systems – We establish reliable data flows between shipping line documentation, customs systems, and yard planning platforms, ensuring hazardous cargo information reaches automated systems accurately and in time for planning decisions.
  • Training programmes for operations teams – We develop practical training that helps planners and supervisors understand how automated segregation works, when to trust system decisions, and how to identify situations requiring manual review.
  • Ongoing optimisation support – We provide continued analysis of segregation compliance and operational performance, identifying opportunities to refine rule configurations and improve the balance between safety requirements and yard utilisation.

This approach addresses the practical realities terminals face when implementing automated hazardous cargo planning, ensuring systems deliver both regulatory compliance and operational efficiency from day one.
