COMMITTEE V.3 MATERIALS AND FABRICATION TECHNOLOGY

Due to the past crises, the shipbuilding and offshore industry has realised that new innovative designs and design and production methods are necessary to decrease operational costs, production costs and emissions, while meeting the changing rules and regulations. This ISSC-V.3 report is discussing recent development in materials and fabrication technology applied to ship and offshore structures. Chapter 2 focuses on worldwide trends in materials and fabrication methods. Developments in metallic and non-metallic structural materials are dealt in Chapter 3. Advances in fabrication and joining technologies such as welding are increasing. Some main areas of applications and research in those areas are described in Chapter 4. Innovative development about corrosion protection systems are presented in Chapter 5 while Chapter 6 give an overview about the application of production simulation and virtual reality to improve the production management of ship and offshore structures. The ISSC-V.3 technical committee has performed a benchmark to define a Best Practice Guideline to use Computational Welding Mechanics tools (CWM) in shipbuilding and offshore industry. To achieve this objective various experimental welding tests have been performed in order to give a reference point. Both the residual welding distortions and residual stresses have been compared between numerical simulations and welding experiments for a common “T” welded assembly used in the shipbuilding industry. However, it has been decided to publish the results of this study in a separate document. Nevertheless, Chapter 7 of this report presents the state of the art as well as the experimental test case that has been analysed.
