The boats are transported, on trolleys or cradles, to or from construction and maintenance berths and buildings. This zone can be built in a single or double level, each with its specific design for the rail system. Special attention should be paid to the rail transition areas between the shiplift, carriages and the dry berths.
Single Level Transfer: The normal single level system is where rails are installed at ground level with cross overs to provide system that allows the transfer of carriages from sea to land. and then at 90 degrees. This means the vessels can be moved around the yard with maximum flexibility use.
Dual Level Transfer: In some yards the transfer is carried out at two levels, where the vessels are transferred to specific dry berths. These could be washdown, painting or welding areas.
