CoLoCa - Container Loading Calculator

Floods & Severe Weather: CoLoCa in Logistics Crises

Natural disasters such as floods and severe weather force freight forwarders, logisticians, and exporters to make short-term, often existential decisions. Blocked roads, damaged warehouses, and closed ports require immediate replanning — not only of the route but also of the use of the right containers. In such situations, flexibility combined with precise container planning is crucial.

Typical problems in crisis logistics

• Blocked routes or partial road failures prevent planned tours.
• Warehouse areas become unusable due to water or storm damage; goods must be reloaded or shipped immediately.
• Time-critical deliveries risk being delayed, resulting in contractual penalties and loss of customers.
• Lack of transparency about volume and utilization prevents quick decisions.

Crisis logistics means acting quickly and data-driven: route optimization, finding new transshipment points, and optimally loading containers.

How CoLoCa supports concretely

CoLoCa is a container loading calculator that offers freight forwarders and logistics professionals concrete advantages in such situations:

• Immediate volume calculation: Whether entering dimensions (mm, cm, m, inch, ft) or direct volume input (m³/ft³) — CoLoCa calculates in real time and shows exact results with 3 decimal places.
• Container utilization for standard container types: 20ft, 40ft, 45ft (Standard and High Cube) including internal dimensions and volume (e.g. 40ft Standard: 67.69 m³; 45ft High Cube: 84.16 m³).
• Color-coded load indicator (Green 0–70%, Yellow 70–90%, Red 90–100%, Black >100%) for a quick assessment of whether a container still has reserve capacity or would be overloaded.
• Unlimited positions: Many packages or pallets can be entered, changed, or deleted individually — ideal when shipments must be newly consolidated.
• Sharing calculations: Generated plans can be shared via link — practical for communication with drivers, handling facilities, and customers.

These features enable quick decisions: Which container fits? Is one 40ft High Cube enough instead of two 20ft? Where is there still reserve?

Case study: Freight forwarder reroutes 5 containers in 2 hours

Situation: After severe flooding, the planned route to the destination port is blocked. A freight forwarder must reroute 5 containers at short notice and bring them to an alternative transshipment point.

Procedure with CoLoCa:

1. Inventory: Material quantities and dimensions of the cargo were recorded (pallets, oversized cargo, individual pieces).
2. Quick calculation: Volumes and utilization for different container combinations were calculated in CoLoCa (e.g. 3×40ft HC + 2×20ft Standard vs. 5×45ft Standard).
3. Selection: 5×40ft High Cube proved to be the most efficient option (volume reserve and better stacking options).
4. Communication: Share links with the calculations were sent to the handling facility and driver — direct confirmation possible.

Result: Recalculation, decision, and transshipment coordination were achieved in 2 hours. Delays were minimized and the shipments could be transported with optimal container choice.

Practical tips for quick emergency planning

1. Documentation: Keep dimensions and quantities available digitally (ideally as a template). This saves valuable time during short-term recalculation.
2. Prioritization: Mark time-critical shipments. Not everything needs to be shipped immediately — prioritizing reduces costs and risk.
3. Flexibility with container types: High Cube containers (e.g. 40ft HC, 45ft HC) often offer more volume at similar freight costs and are often the better choice for tall goods.
4. Plan reserve capacities: The target is a utilization in the yellow range (70–90%) — this leaves room for re-stows.
5. Alternative transshipment points: Have a list of preferred alternative ports and warehouses that are reachable at short notice.
6. Communication via share link: Use shareable calculations to avoid misunderstandings and make quick decisions.

Checklist for your emergency planning (immediately applicable)

• [ ] Current inventory list with dimensions available
• [ ] Standard container types already assessed (20ft/40ft/45ft, Standard/High Cube)
• [ ] Predefined priorities for shipments
• [ ] List of alternative routes and transshipment points
• [ ] Contact channels to drivers and handling facilities active
• [ ] Pre-made calculation templates (pallets, number of pallets, oversized cargo)
• [ ] Persons responsible for quick decisions named

Route optimization in combination with container planning

Route optimization and container planning belong together: If a road fails, the new route must not only be passable but also provide the appropriate capacity at transshipment points and the suitable containers. Consider:

• Restrictions at intermediate stops (e.g. weight limits, access times)
• Available stacking capacity in alternative warehouses
• Intermodal options (rail/ferry) for blocked routes

CoLoCa helps make the container decision quickly — leaving more time for the actual route optimization.

Conclusion

In floods and severe weather, fast, well-founded decisions about container choice and transshipment are essential. CoLoCa offers precise volume calculation, clear utilization indicators, and shareable plans that enable freight forwarders to act during crisis situations. With clear priorities, prepared templates, and the right container choice, supply chains can be stabilized even in uncertain times.
