is a technical standard published by the American Petroleum Institute (API) that provides structural engineers and safety professionals with a structured approach to managing accidental loads.
Hence, the industry cried out for a edition. That new edition arrived as the 2nd Edition, released in Q4 2019 / Updated 2021 . (Always check the latest revision date – as of 2025, the most current is still the 2nd Edition, with minor corrections).
It is important to address a common misconception: The document is a copyrighted publication of the API, and accessing it legally requires purchase from authorized distributors. api rp 2fb pdf new
API RP 2FB is primarily directed at the new design of offshore structures against fire and blast, but it is also widely used to verify the safety of existing structures. The document’s scope is broad, covering both fixed and floating structures used as offshore oil and gas production systems, including semi-submersible vessels, ship-shaped vessels, Tension Leg Platforms (TLPs), and Spars.

The standard guides engineers in calculating the heat flux ($kW/m^2$) applied to the steelwork. The key parameter is the Heat Release Rate (HRR) , which determines the severity of the thermal environment.
