Ship Design III
Structural midship section design, classification society rule compliance, quasi-static hull girder loads, transverse bulkheads, and finite element analysis.
The preliminary design of the containership is concluded from the previous semester in Ship Design II. Classification rules are revisited with focus on understanding the terminology and the relevant structural requirements applicable to the project. Hull girder longitudinal strength requirements are evaluated based on classification society rules and quasi-static loading analysis using a longitudinal weight distribution method and general hydrostatics software. Using two representative ship operating condition and the calculated loads, the students are asked to design the midship section of a ship and verify that the longitudinal structure meets classification society requirements. Design of transverse structural members such as bulkheads and/or deep web frames is carried out, with verification that they meet classification society requirements. Structural performance of the hull girder is then analyzed. Finite element analysis (FEA) software is used in the structural design. Material selection, structural weight, producibility, and access for inspection and maintenance will be emphasized during the design.
