Abstract Compared with other ship types, bulk carriers have the advantages of relatively easy process and mature technology. And as one of the main ship types in the design and manufacture of our country, there is a huge market demand. This design of the ship is 79600DWT bulk cargo ship, as its technical characteristics, accordance with the 《steel seagoing vessel rules for the classification and construction》(2006) to the calculation and the required strength.This article is focused on the calculation of the cargo area and the area of bow and stern.This ship is a steel cargo ship.The cargo area and engine room are equipped with the double bottom.The cargo area is also equipped with the double hull.The cargo at the bottom and the deck use longitudinal framing. The non-cargo area use the transverse framing.

     The main contents include :

     1.Development situation and classification of cargo ship. Structure specification design overview and design problems exist.

     2.79600DWT offshore cargo ship structure specification calculations.

     3. The cross-section of the cargo area bending strength check.

     4.Mapping of the midship section, basic construction and the structure drawing of  the  bulkhead  of  the cargo hold.
