Braced and free-standing caissons, jackets, towers, and monotowers.
For decades, the offshore oil and gas industry relied heavily on Working Stress Design (WSD), also known as Allowable Stress Design (ASD). API RP 2A-WSD applies a single safety factor to the ultimate strength of materials to ensure structural integrity. While straightforward, WSD does not explicitly account for the distinct variability of different load types, such as the predictability of dead loads versus the extreme uncertainty of environmental loads like waves and earthquakes.
Uses separate partial safety factors for loads (uncertainty in environmental and gravity forces) and resistance (uncertainty in material strength and fabrication). Reliability:

This article explains what API RP 2A-LRFD is, why the 2019 edition matters, the key technical changes from previous versions, how to legally obtain the PDF, and how to apply its principles to real-world offshore projects.
Detailed guidance on designing structural members, joints, connections, and piles.

“You’re looking for the 2019 LRFD?” she said, yawning. “Check your spam folder. I sent the whole class a link last year.”
If you are looking for the "paper" to understand the updates, the 2019 Errata focused on:
The American Petroleum Institute (API) publishes the industry's most authoritative guidelines for offshore structural engineering. For engineers and project managers working on fixed offshore platforms, is an essential document. This guide will walk you through everything you need to know about this critical standard—from its technical scope to how to obtain an official copy. The edition listed is API RP 2A-LRFD:2019(R2024)
Enter the (Recommended Practice for Planning, Designing, and Constructing Fixed Offshore Platforms—Load and Resistance Factor Design). As the cornerstone of offshore structural engineering, the standard ensures that fixed steel platforms—whether they are oil rigs or offshore wind turbine foundations—are designed to withstand both operational and extreme environmental loads. Understanding the LRFD Methodology
If you are looking to purchase, remember to check for the API RP 2A-LRFD:2019 (R2024) reaffirmation to ensure you are using the most current revision.
: The standard covers everything from initial design and fabrication to transportation, installation, and eventual removal.
