Schematic cross-section through an open ship with a large degree of deck opening
In shipbuilding, the degree of deck opening describes the ratio of the hatch size to the existing deck area above the hold of a cargo ship. A large degree of deck opening results in little under- stowage (the part of the hold that is outside the hatch area under the fixed deck ), while a low degree of deck opening leads to a large under-stowage and thus to a longer stowage path in which the cargo parts are transported during loading and unloading Stowage process moved in the horizontal direction, so be stowed under. In the case of open ships , the degree of deck opening is so great that only very little or almost no underwater storage remains, which leads to faster handling times. If the degree of opening of the deck is increased, the remaining deck area and its substructure must be designed with a stronger structure in terms of shipbuilding in order to be able to absorb all bending and torsional forces occurring during ship operation.
