This work is concerned with the design of floating objects, particularly with changes that have taken place over the last years in this field. The principal aim of the author was to sum up and generalize the results of his studies on the whole range of problems in floating objects designing, based on his extensive experience in ship design including research development activities concerning new types of objects and their systems. The work presents an outline of a modernized and rational design methodology applied to floating objects (including cargo vessels), as well as tools of its implementation. Above outline has been based on conclusions from critical analyses of current ship design methodology, actual trends in the development of floating objects, evolution of methods actually used for production and their impact on the design processes. The results are presented in the following chapters. Chapter 1 is devoted to an analysis of the current state of ship design. The influence of shipbuilding processes on shipyard competitive ability, as well as the impact of shipyard production processes rationalization and of new trends in the construction of modern floating objects on the design methodology are considered throughout the chapter. The scope of necessary modifications of design methodology is referred. Chapter 2 deals with theoretical foundations of the design process. Starting from the general design theory of Yoshikawa, extended by Tomiyama, an attempt was made to define a design model that would suitably reflect the real design process for floating objects. For this aim, several existing design models were studied in aspect of their efficiency to create design solutions. A need for detailed analysis of design decomposition as the principal early design tool was observed in the case of models selected for further analysis. This topic is further discussed in Chapter 3 which introduces three types of design decomposition applied by the author to the design process: (1) systems decomposition, (2) geometric decomposition and (3) decomposition of design process. Information generated by system decomposition can be used for design synthesis. Geometric decomposition has been created as a method of spatial modelling of a floating object and is useful for 3-D model forming. Decomposition of design process is understood as a sharing of the design process into primary, secondary and ancillary design problems, which in fact are the basic factors that organize the design process. Chapter 3 lays down the theoretical base and lists initial assumptions for a modernized design methodology which is presented in Chapter 4 as an original contribution of the author. The methodology detailed in Chapter 4 applies to the preliminary stages of design. Preliminary stages of design are understood as the stages before signing of the contract to build the vessel and the basic design stage in some extent, both of which constitute the most intense period of design creativity and play a decisive role as to technical solutions adopted and costs as well. This Chapter defines the model of real design process of a floating object and the principal scheme of the design process. The consecutive steps of design process are presented in this chapter i.e. pre-design estimations and analysis, space-function creation stage, hull structure design (modelling) and modelling of systems. The design process is shown in the form of design information workflow charts where each design activity is presented by input data, output (results of activity), control (design limitations) and mechanism supporting the activity (man, software, machine). Attention is devoted to analytical work and computations which play the role of control factors over the design process. The processes of the vessel's mass and costs estimating as well as planning activities are also considered. An outline definition of multi-dimensional modelling of floating object is given in Chapter 5. The result of such modelling includes not only 3-D imaging of properties of the object and its systems but also the rendering of all attributes necessary for the design and production, starting from its immaterial functional structure, through logistics and mass data, results of computations, and ending with information on planning activities and building strategy. A description of the floating object model shown in Chapter 5 serves as an example of the proposed methodology integration with new tools currently developed for the design of floating objects. Chapter 6 includes final remarks and conclusions, as well as a discussion on performed research practical applicabillity.
