SUMMARY
IMPORTANT NOTE: Technical Note 11 has now been superseded by Technical Note 13
This Technical Note updates and expands certain aspects of the guidance on fire engineering given in the Interim Guidance Notes, FABIG Technical Notes 1 and 6 and the UKOOA guidance. The contents are as follows:
-
Section 2 covers hydrocarbon jet and pool fires, giving simplified guidance on estimating fire loads for design
-
Section 3 gives guidance on heat transfer and temperature development in steel members
-
Section 4 summarises general principles of passive fire protection (PFP), noting relevant standards
-
Section 5 gives strength and stiffness data for steel and stainless steel at high temperatures
-
Sections 6 and 7 describe the Eurocode basis of design and the process for determining the fire resistance of structural steel members in accordance with Eurocode 3
-
Appendix A describes a probabilistic approach for determining offshore fire loads
-
Appendices B and C give properties of carbon and stainless steel at high temperatures
-
Appendices D and E give further information on the structural Eurocodes and two design examples of fire resistant design to Eurocode 3.
The scope of this document is limited to hydrocarbon fires and the response of steel members in the types of structures typically encountered in the oil and gas industry.
