Shipbuilding industry has a very specific character as compared to that of any other manufacturing industry. It naturally implies that the structure will be able to sustain all the service loads and also at the same time the hull form should be hydrodynamically efficient. And needless to say, should ensure safe transportation of the cargo. The internal structural arrangement should be such that it will facilitate loading, stowage and unloading of the cargo. the hull form may not be very different, but the internal structural arrangement will be very much dependent on the type of cargo the vessel needs to carry. These vessels, their outward features, i.e. Passenger ships and inter island ferries also play a very important role in transportation as well as tourism.

This trade will naturally involve very high volume of transportation of all kinds of items starting from bulk grain, ore, coal to crude, automobiles and various other kinds of farm and engineering products. Over the years as international trade increased and also bulk transportation of goods became more and more necessary, various types of ships came into being depending on the type of cargo that needs to be carried. Lastly, a chapter on accuracy control based on statistical principles is included, addressing the need for a suitable mechanism to gauge the ranges of variations so that one can quantitatively target the end product accuracy. The nondestructive testing methods that are most relevant to ship construction are explained. In its final section, the book describes in detail various types of weld defects that are likely to occur, together with their causes and remedial measures. Further, the basic principles of distortion prevention, in-process distortion control and mitigation techniques like heat sinking, thermo-mechanical tensioning etc. The mechanisms of residual stress formation and distortion are explained in connection with stiffened panel fabrication, with an emphasis on weld induced buckling of thin panels. Friction stir welding as one of the key methods of solid state welding as applied to aluminum alloys is also addressed. Various fusion welding methods, MMAW, GMAW, SAW, Electroslag welding and Electrogas welding and single side welding are explained in detail. The concept of line heating for plate bending is introduced.Welding power source characteristics, metal transfer mechanisms, welding parameters and their effects on the fusion zone, weld deposit, and weld bead profile are discussed in detail. Various methods of steel material preparation are discussed, and plate cutting and forming of plates and sections are explained. With regard to construction materials, the book discusses steel, aluminum alloys and fiber reinforced composites. The midship sections of various ship types are introduced, together with structural continuity and alignment in ship structures.

It presents in detail double bottom construction, wing tanks & duct keels, fore & aft end structures, etc., together with necessary illustrations. along with structural subassemblies like floors, bulkheads, inner bottom, decks and shells. The book covers structural arrangement with longitudinal and transverse framing systems based on the service load, and explains basic structural elements like hatch side girders, hatch end beams, stringers, etc. The contents of the book are logically organized and divided into twenty-one chapters. This book addresses various aspects of ship construction, from ship types and construction materials, to welding technologies and accuracy control.
