Case Study: 183 BESS Units. China to Bulgaria. 30 Days.
When time, regulatory compliance, and cargo sensitivity intersect, logistics becomes a strategic decision. Here is how we executed the project.
The Challenge
183 Battery Energy Storage Systems
Heavy containers (35–45 tons)
DG cargo classification
Strict deadline
Limited carrier acceptance
Risk of storage penalties
Commissioning timeline was critical.
The Solution
Chartered a dedicated vessel
Routed via Suez
Coordinated origin & DG documentation
Managed port handling in Varna
Executed inland ADR transport to final site
Risk of storage penalties
Result: Delivered on time. No storage costs. Full operational control.
Which BESS Scenario Are You In?
Every BESS project is different. Your logistics strategy should be too.
Charter Vessel Strategy
Full capacity control. Fastest routing. Best for commissioning-critical projects.
Why BESS logistics is different?
Battery energy cargo is not standard freight. It requires:
UN 3480 / 3481 / 3536 compliance
DG + project cargo integration
Carrier-specific approvals
State-of-charge documentation
Strict commissioning alignment
