The deck cargo is cargo shipments loaded on deck instead of directly in the ship. According to the legislation of several types of cargo must be carried out on the deck, while other types of cargo do this for convenience or to resolve the problem of space when loaded on the ship. The cargo must be kept with care to prevent loss and reduce the risk of injury to the crew, as they will be directly affected by the cargo deck while working on the ship.
