Fire safety assessment and optimal design o passive fire protection for offshore structures

摘要

The article presents a unified probabilistic approach to fire safety assessment and optimal design of passive fire protection on offshore topside structure. The methodology was developed by integrating quantitative risk analysis (QRA) techniques with the modern methods of structural system reliability analysis (SRA) and reliability based design optimisation (RBDO). Reliability analysis methodologies are presented of both plated (e.g. fire and blast walls) and skeletal structures (deck framing), which take into account uncertainties in fire and blast loading, thermal mechanical properties of the steel and insulation.
