Loads considered in the study are still water bending moments, vertical wave bending moments and whipping bending moments, while structural capacity is represented by the hull girder ultimate strength. Load combination between wave and whipping bending moments is considered. The probability of failure is calculated using a first-order reliability method. Sensitivity study is performed in order to investigate influence of the pertinent random variables. The uncertainty model of the basic random variables involved is consistent with the recent proposal by the International Maritime Organization, thus enabling direct comparison of the obtained results with reliability levels proposed by International Maritime Organization.

Main objectives of this research was to develop an integrated multiple criteria decision making environment by using the advanced design synthesis and analysis techniques at the earliest stage of the design process, which innovatively considers structure, production, operational aspects, performance, and safety criteria on a concurrent basis. Such support can be used to make more informed decisions, which in turn will contribute to reducing the life-cycle costs and improving the performance of those ships. The work has been realized through EU FP6 project IMPROVE and tested in through design of three ship of new generations. The product types focused are new generations and innovative concepts of LNG gas carrier, a large Ro-Pax vessel and chemical tanker.

There are however clear signs of recovery in the last year. The shipbuilding industry has realised that, due to the crisis, new innovative designs and design and production methods are necessary to decrease operational costs, production costs and emissions, whilst meeting the changing rules and regulations. In this report ISSC committee V.3 discusses recent development in materials and fabrication technology. Chapter 2 focusses on worldwide trends in materials and fabrication methods. Developments in fabrication technologies, such as welding and corrosion protection are dealt with in Chapter 3. Applications of composite materials are increasing. Some main areas of applications and research in those areas are described in Chapter 4. A comparison of current worldwide standards is made in Chapter 5. Chapter 6 gives an overview of current developments in the linking of design and production in co...
