What can be used to support the accommodation ladder over the side when outriggers are not available?

The J-bar davit is a suitable option to support the accommodation ladder over the side when outriggers are not available. This equipment is designed specifically to hoist and support various loads, including ladders and small boats, making it versatile for different marine operations. The structure of the J-bar davit allows for a secure attachment and operation, which is crucial for safety and functionality when personnel or equipment need to access the vessel from the side. This type of davit is often found in shipboard operations and is specifically constructed for making the task of lowering or raising items easier, whether it involves personnel boarding or equipment transfers.

Using a crane for this purpose would complicate the operation, as cranes are typically employed for heavier lifts and might not provide the necessary stability for a ladder that is expected to support people. A hoisting block, while useful for lifting, does not provide the necessary support structure to hold the ladder securely in place. A support frame could potentially work, but it is not specifically designed for this purpose in the way that a J-bar davit is. The J-bar davit's intended function ensures that it is the most reliable and appropriate choice for this scenario.
