It involves three parts-the overall design part, structure design part, summary and discussion design part. Firstly, the design of the overall part: analysis the mission statement and the information of the parent ship, and using parent type transformation method to decide the main dimensions designed ship and the offsets table, then drawing ship lines plan and the general arrangement plan of the new ship. Secondly, the design of the structure part: according to the “Rules for classfication of sea-going steel ships(2006)”, carry out the structure design and select the structural materials reasonably, calculate and verify the longitudinal strength, then analysis the results of the design, lastly, draw the basic structure plan and typical cross section plan. Thirdly, the summary and discussion part: summarizing the experience and analyzing the deficie
