Ship repair projects are short in time with high complexity and uncertainty. These characteristics means that your project could derail easily and when you realize that there is or there are several issues, perhaps it is too late. Over the course of history, it has been known that some shipbuilding and ship repair projects have been completed with cost overruns and delays - highlighting the need for tools to control projects and make timely informed decisions.
There is often a deep disconnect between the project team's goals and those of the organization. Senior management wants "profitable" projects, but is only able to quantify its wishes in terms of the traditional project management elements: schedule and cost. To operate smoothly, the entire organization must be driven by the single goal of project
Marine Traffic facilitates much of the world's trade; the marine traffic sector is influenced by many factors that affect its operations, development and direction.That factors such as shipbuilders, classifications societies, ship owners, ship management, ship chandlers, ship suppliers, ship operators, port & port facilities, ship agency and ship repair yards.The ship repair activities are considered the heart & the focus interest of any ship yard which are affected on marine traffic sectors as I had mentioned above.The main purpose of this guide book is to make available to all ship repair yard managements and their ship repair managers (SRM) a ready reference, Ship repair yard management should be considered the role of the ship repair managers as very important to keeping in his mind that he is the yard representative towards ship owner in the project he is handling.To assist all new ship repair managers in performing their daily activities, I have written this guide book based on my own practical work experiences, in order to guide them for a proper way of the project management in marine traffic sectors.

This book highlights the main features of shipbuilding management which lead to successful completion of shipbuilding projects. A brief review of the market context for the industry, its historical development are given to explain how shipbuilding arrived at its current structure. First pre-production including design, planning, cost estimating, procurement of materials and sub-contracting. Then, the production sequence outlines part preparation, hull assembly and construction, outfitting and painting, testing and completion. The importance of human resources and management organisation are explained. Building a ship is a complex project, so the principles of project management are described, first in general terms and then with specific reference to their application in shipbuilding. Finally managing the progress of a shipbuilding project and achieving completion are emphasised.
Many smaller shipyards are currently struggling to survive in the marketplace. Most shipyard managers recognize that improving the productivity of the production labor force is sorely needed. Direct attempts at improvement are often frustrated, or produce only short-lived advantages. Use of a larger whip usually antagonizes the situation and makes improvement even less likely in the long run. Clearly, a different focus may be the key to success. Production workers receive considerable support from other segments of the shipyard. They are furnished with plans, work packages, facilities, tools, work places, material, and similar items indispensable to accomplishing the work. If these items of support are missing, or confusing to the worker, or arrive - late, or are in unusable condition, or otherwise do not provide the vital support needed, then there is little that the production worker can do about it other than gird himself for an onslaught of criticism about his productivity.
This book addresses various aspects of ship construction, from ship types and construction materials, to welding technologies and accuracy control. The contents of the book are logically organized and divided into twenty-one chapters. 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. along with structural subassemblies like floors, bulkheads, inner bottom, decks and shells. It presents in detail double bottom construction, wing tanks & duct keels, fore & aft end structures, etc., together with necessary illustrations. The midship sections of various ship types are introduced, together with structural continuity and alignment in ship structures. With regard to construction materials, the book discusses steel, aluminum alloys and fiber reinforced composites. Various methods of steel material preparation are discussed, and plate cutting and forming of plates and sections are explained. 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 fusion welding methods, MMAW, GMAW, SAW, Electroslag welding and Electrogas welding and single side welding are explained in detail. Friction stir welding as one of the key methods of solid state welding as applied to aluminum alloys is also addressed. 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. Further, the basic principles of distortion prevention, in-process distortion control and mitigation techniques like heat sinking, thermo-mechanical tensioning etc. are dealt with in detail. 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. The nondestructive testing methods that are most relevant to ship construction are explained. 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.
