The deck is an important component of the hull. It is a plane structure above the inner bottom of the ship structure, used to cover the inner space of the ship and divide it horizontally into layers. The deck is the steel plate on the ship beam, which separates the hull into upper, middle and lower layers.
The long deck at the bow and stern of the uppermost deck is called the upper deck. If all openings on this deck can be sealed and ensure watertightness, this deck can also be called the main deck, which is also called the tonnage deck during measurement. A small number of ocean-going ships also have an upper deck that penetrates the bow and stern on the main deck. Since the openings cannot guarantee watertightness, they can only be called shelter decks. The long decks below the main deck are called the second deck, the third deck and so on from top to bottom. Above the main deck are short decks, which are customarily named according to the name or purpose of the cabin on that deck. Such as bridge deck, life-boat deck and so on. The middle deck of the wooden deck barge is also called the deck, which is generally movable.
