Abstract
Oil sands projects have unique features due to process conditions and environmental factors. Process safety risks such as fire hazards are typically mitigated through application of Passive Fire Protection (PFP). Cementitious and intumescent PFP types are commonly used to protect plant structures. Cladding type or flexible jackets are more common for fire protection of piping systems and safety critical components including equipment, valves and instrumentation systems. Due to weather conditions, application of PFP products at plant site or modular construction requiring transportation over long distances may pose risks for major projects. This study aims to share lessons learnt and recommendations for selection of PFP types for oil sands projects and facilities with similar environmental and process conditions. Critical considerations for selection of PFP type in the oil sands fields are discussed in this study with respect to abrasion resistance, short- and long- term integrity, and corrosion under insulation risks. This study provides case studies and recommendations for PFP selection and application at cold regions where the facility has high momentum jet fire risks similar to those at oil sands facilities. Also, methods to optimize PFP application are discussed so that required coating quantities can be minimized and potential integrity issues can be mitigated. This approach is expected to be beneficial for reducing coating related Capital Expenses (CAPEX) and Operational Expenses (OPEX) at oil sands and other process plants where there are fire risks.
