Design, Operation and Regulation for Safety
The main idea at the root of the Safedor project is the so-called 'design for safety' concept, which describes the integration of safety as a design objective in the design process to minimise risk, alongside traditional design objectives such as minimising power requirements and maximising cargo carrying capacity. Integration of risk and reliability analysis methods into the design process for ships therefore leads to 'risk-based ship design', the subject of Safedor. It was decided early in the development of Safedor to focus only on four ship types having significant economic value for Europe: cruise ships, RoRo/RoPax, gas tankers and container vessels. Safedor later also included oil tankers. These vessels are the most knowledge intensive and safety critical which underlines the strategic importance of Safedor to the European maritime industry. It is expected that these ships will be favoured by the new risk-based approach and that the future removing of regulatory constraints will open the route to innovative ship designs and, thus, to improved competitiveness for the companies involved. Safedor aims to attain this objective by answering two fundamental needs: - risk-based ship design and approval will satisfy the European maritime industries' need to deliver ever more innovative transport solutions to their customers. - risk-based ship design and approval will also satisfy the European society's need to have increasingly safer transport. Safedor research activities address - and provide solutions to - both aspects and, thus, deliver important building blocks for Europe to sustain world-leadership in safety-critical and knowledge-intensive ships, maritime services, products, equipment and related software. Increasing safety and security of maritime transport cost-effectively is achieved by treating safety as a design objective and not as a constraint, as in current ship design. Increasing the competitiveness of European industry is achieved by systematic innovation in design and operations encouraged by modernising the maritime regulatory system towards a risk-based framework. The Safedor project has produced a mid-term report highlighting the key achievements obtained two years into the project. New tools and significant enhancements of existing ones were developed, addressing transient flooding, structural integrity, dynamic intact stability, collision and grounding, and fire. The main objective was to provide computational tools to predict failure probabilities which can be used as input for a risk model and -at the same time- respond to changes in design parameters likely used as risk control options. Following the development of a high- level approval process for risk-based ships and related risk acceptance criteria in year 1, developments in year 2 focused on the approval process and risk acceptance criteria for risk-based ship systems and functions. A major achievement of year 2 has been the implementation and application of the Safedor approach to the design process of eight novel ship designs. This design activity addressed two cruise ships, three ropax, one gas tanker, one oil tanker and one container vessel designs. From the eight completed novel ship and system designs, the two best have been selected by a formed peer evaluation panel, considering economic, environmental, safety impact, feasibility and rule challenge criteria. These two designs will continue into year 3 and 4 with the detailed design and are expected to eventually commercialize their ideas by the end of the Safedor project.
