Ship double banking is a term used to describe a situation where two vessels are moored or anchored together in close proximity. This can occur for various reasons, such as congestion in a port or limited available berths. I have personally witnessed and been involved in double banking operations during my time working in the maritime industry.
One type of double banking operation occurs when a port authority orders a vessel to double bank due to congestion in the port. This typically happens when there are more vessels waiting to be unloaded or loaded than there are available berths. In this situation, one vessel is already docked at the berth, and another vessel is directed to anchor alongside it. This allows both vessels to share the same berth space, effectively doubling the capacity of the port.
During my experience in a busy port, I have seen firsthand how double banking can help alleviate congestion and ensure the efficient flow of cargo. It is an impressive sight to witness two large vessels side by side, their towering hulls creating a temporary but effective solution to the limited berth availability.
It is important to note that in double banking operations, the cargo from both vessels is typically discharged ashore. This means that the cargo is unloaded from the vessels onto the port facilities, rather than being transferred directly between the vessels. This is different from other types of ship-to-ship transfers, where cargo is transferred directly from one vessel to another.
Double banking requires careful coordination and communication between the vessels, port authorities, and other stakeholders involved. The vessels must be securely moored together to ensure stability and safety. Tugboats and other assisting vessels may be used to help maneuver and position the vessels during the double banking operation.
In some cases, double banking may also involve the transfer of personnel and supplies between the vessels. This can include crew changes, provision deliveries, or equipment transfers. Ensuring the smooth transfer of people and goods between the vessels requires thorough planning and coordination to minimize disruptions and ensure the safety of all involved.
Ship double banking is a temporary solution to address port congestion and limited berth availability. It allows for the efficient use of existing port infrastructure and helps keep the flow of cargo moving. While it may require additional coordination and resources, double banking operations can be an effective way to manage the challenges of a busy port environment.
