Where should the hull number be located on a barge?

The hull number of a barge is typically located on the main beam inside a cargo hatch. This positioning ensures that the hull number is securely displayed in a location that is accessible for inspection and not easily worn or damaged. The main beam is a structural part of the barge that is integral to its design, providing strength and support, while the cargo hatch represents an operational area frequently accessed for loading and unloading.

Placing the hull number in this area also standardizes where it can be found, making it easier for port state control inspectors to verify the vessel's identity and compliance with regulations. This visibility is crucial during inspections as it helps in maintaining safety and regulatory compliance by allowing for proper documentation and identification of the vessel.
