What changes in Baltimore
Baltimore's cargo profile — vehicles, machinery and breakbulk — does not generate lightering demand. Ro-ro cargo cannot be transferred between vessels at sea in any practical sense, and the port's container and bulk volumes work alongside.
Transfer activity is limited to bunkering. For operators, the useful point is that a draft problem at Baltimore is solved by cargo planning or by tide, not by an offshore operation, because the service infrastructure for that does not exist here.
- The ro-ro and breakbulk cargo profile does not generate lightering demand.
- Vehicle cargo cannot practically be transferred vessel to vessel at sea.
- Transfer activity is limited to bunkering.
- Draft problems are solved by cargo planning or tide, not offshore transfer.
- No local lightering service infrastructure.

The Baltimore cluster
Baltimore is the leading US ro-ro and heavy-machinery gateway, handling more cars and construction equipment than any other American port. That specialism shapes everything: the terminals, the labour, the surveying capability and the claims profile, which is far more about cargo damage than container throughput.
- Leading US ro-ro and vehicle gateway
- Heavy machinery and breakbulk
- Coal export terminals
- Deep inland rail reach
The fundamentals
A ship-to-ship transfer moves cargo directly between two vessels moored alongside each other, either at anchor or underway, without either touching a berth. It is a routine commercial operation in the oil, chemical, gas and dry bulk trades, not an exceptional one.
Transfers happen for three distinct reasons, and confusing them causes most of the planning errors:
This is the shared explanation, common to every market. The full treatment is in Ship-to-Ship Transfer: How STS Operations Actually Work.
Frequently asked questions
Can vehicle cargo be lightered?
Not in any practical sense. Ro-ro cargo requires ramps and a fixed relationship between vessel and shore, which is why lightering plays no part in Baltimore's operations despite its position up a long bay.
How are draft constraints managed at Baltimore?
Through cargo planning and tidal windows rather than offshore transfer. There is no local lightering service base, so a draft problem has to be solved before the vessel arrives.
