Incorporating the RISFIM approach for passive fire protection in a safety strategy framework: Evaluating the temperature ball model for passive fire protection of pipe supports in offshore brownfield projects

Abstract

This thesis investigates the effectiveness and applicability of the Risk-based Simplified Fire Models and Methods (RISFIM), particularly the temperature model, in assessing the necessity of passive fire protection on pipe supports in offshore brownfield projects. The study addresses the industry’s need for simplified, cost-effective analytical methods to determine structural fire integrity and minimize the resources currently expended on detailed analyses. The research includes the development of RISFIM-based workflow tailored specifically for offshore modifications, an evaluation of the temperature ball model’s practical effectiveness using real data from ongoing projects, and recommendations for integrating these simplified methods into Aker Solutions’ existing project execution models. Additionally, the thesis identifies competencies required for implementing RISFIM and highlights existing gaps within industry practice. The findings demonstrate the potential of RISFIM methodologies to streamline passive fire protection decision-making processes, ensuring safety while reducing complexity and costs in modification projects. The research concludes with suggestions for standardization with engineering practices and highlights areas for further investigation to continuously improve fire safety engineering.
