A pivotal concept introduced in API RP 2FB is the acceptance of plastic deformation. In a

An Overview of API RP 2FB: Recommended Practice for Design, Fabrication, and Testing of Fixed Offshore Oil and Gas Platforms

For the absolute latest “new” version – check the API website (api.org) for any 2025+ addenda or a potential Second Edition. If a revised PDF has been released after 2023, focus on changes to polyester creep factors and digital twin acceptance, as those are the two most active research areas in mooring engineering.

: Bridges the gap between safety management (RP 75) and structural design.

You cannot simply take a chain catalog and apply a safety factor. You must compute environmental contours, run dynamic simulations, and apply load factors ranging from 1.10 to 1.50 depending on consequence category (L1, L2, L3 for low, normal, high consequence).
