This main aim of this work is to develop a “design for safety” based risk assessment technique for the offshore platforms in order to facilitate decision making. This is achieved through detailed examination of related risks, and review of relevant literatures and traditional safety assessment methods leading to the development of a new knowledge-based risk assessment method (KBRAM) through the research methodology process. The methodology involves detailed definition of the research aim and objectives, further literature review on risk analysis and the related topics of safety assessment and safety management systems. This process laid the foundation for the establishment of a framework for the integration of design for safety and fuzzy reasoning approach to model the risk assessment procedure for offshore platforms. The research procedure requires collection of data which was obtained from the industry in this instance. The collection methods involve surveys visit interviews and questionnaires which together constitute vital information required for test running the model and conduct preliminary validation studies with regard to offshore platform risk assessment to enable provision reaching some conclusions. The results obtained through testing of KBRAM using data collected from the industry show the determination of risk level classification has been improved compared to the one obtained using same data on the traditional fuzzy two-input parameter risk assessment method (TPRAM) due to the addition of a third parameter in the KBRAM. In conclusion, the above result satisfy the research aim of facilitating decision-making process based on reduced cost of safety due to more efficient risk evaluations.
