API RP 2A-LRFD (2019), whose full title is Planning, Designing, and Constructing Fixed Offshore Platforms—Load and Resistance Factor Design , is the second edition of this recommended practice. It is the Load and Resistance Factor Design (LRFD) counterpart to the more traditional API RP 2A-WSD (Working Stress Design).
The combined environmental and operational loads, multiplied by their specific factors, exceeded the factored resistance of the soft soil by 14%. The Valiant would not stand for 100 years. It might not stand for five. A resonance in the soft clay would amplify the wave loads, turning the jacket into a slow, twisting metal disaster.

While the foundational LRFD framework was established in the 1993 first edition, subsequent updates, including revisions aligned with ISO 19902 standards and updated API releases, introduced critical enhancements:
Resistance formulas for axial tension, compression, bending, shear, and combined stresses in cylindrical members. The Valiant would not stand for 100 years
: The strength of material elements (yield strength, buckling capacity) is reduced by resistance factors (
(Load Factor): Multipliers usually greater than 1.0 that account for the variability and uncertainty of specific load types. Qicap Q sub i
