This design is mainly to the 2000m3 sand carrier structure and strength calculation analysis for the design, reference to the design plan requirements of the Vessel, and the ship's main dimensions, general arrangement and sheer, accordance with the "Steel Ships Classification and Construction canon"(2006) calculated on the hull structure. This design is divided into two parts, Part 1: according to the "Steel Ships Classification and Construction canon"(2006) and relevant regulations, calculate the size of the various components and plate, according to the calculation result of selecting the required plate and section bar, finally, list summarizes the size of main structure. Part 2: according to the first part the calculations made to calculate of the size of the bottom, deck and various parts of the superstructure components, according to designing the requirement for the task, map out the ship's basic structure and transverse section, reflect the size of the design of the ship's bottom and main deck, side, the cabin area and superstructure components and the main components. Part 3, according to the size of component calculated and the transverse section had draw to check the ship strength, in order to achieve the required strength. The vessel length 83.52m, design draft 3.3m, the design displ
