Bulwarks fitted on weather decks are provided as protection for personnel and are not intended as a major structural feature. They are therefore of light scantlings, and their connections to the adjacent structures are of some importance if high stresses in the bulkwarks are to be avoided.
Freeing ports are cut in bulwarks forming wells on decks in order that water may quickly drain away. The required area of freeing ports is in accordance with the Load Line Rules 1968.
Note :
CONSTRUCTION OF BULWARKS
Bulwarks should be at least 1m high on the exposed freeboard and superstructure decks, but a reduced height may be permitted if this interferes with the working of the ship.
