Currently, in SDC Verifier, it is possible to perform plate buckling check according to ABS Buckling and Ultimate Strength Assessment for Offshore Structures (April 2004) and ABS Floating Production Installations (July 2014), ABS Requirements for Buckling and Ultimate Strength Assessment for Offshore Structures (2022), and ABS Rules for Building and Classing Floating Production Installations (2024).

ABS 2004 Guide for Buckling and Ultimate Strength assessment for offshore structures, published April 2004 (updated February 2012)
Section 3 Plates, Stiffened Panels and Corrugated Panels are implemented in SDC Verifier.
An important aspect in the design of an offshore steel structure is the buckling and ultimate strength behavior of its fundamental structural components. Calculations according to ABS Plate Buckling (2004) standard are performed for each element with converted stresses (into plate direction) or Plate Average Stresses and using Plate dimensions.
The standard deals with ensuring high technical quality plate buckling check. Plate Buckling Check is calculated on Sections.
With the help of Panel Finder it is possible to automatically recognize Section and Plates with their dimensions. Check is passed if Ultimate Strength Limit ≤1 and Buckling State Limit ≤1.

ABS 2014 Guide for Building and Classing – Floating Production Installations, published July 2014
Part 5A Ship-Type Installations are implemented in SDC Verifier.
To ensure high technical quality plate buckling check according to ABS 2014 Guide for building and Classing – Floating Production Installations, published July 2014.
For individual loads and loads sets, plate buckling is calculating based on formulas using stresses from the load.
For Load Group plate buckling is calculated as an envelope. Load Group items are calculated using formulas and then min/max/abs is found. Load Group contains the worst values for each parameter and gives a possibility to check the highest Ultimate Strength and Buckling State Limits for all items at once.
Ultimate Strength Limit and Buckling State Limit depend on plate results (stresses) and the plate dimensions (length, width, and thickness).

ABS Requirements for Buckling and Ultimate Strength Assessment for Offshore Structures, published July 2022
This standard is implemented based on the following part of the standard: Subsection 3/3 Plate Panels.
The specific Rules and Guides that these Standard supplements are the latest editions of the Rules for Building and Classing Offshore Installations [for steel structure only], Rules for Building and Classing Mobile Offshore Units (MOUs), Rules for Building and Classing Single Point Moorings (SPMs), Rules for Building and Classing Floating Production Installations (FPIs) [for non-ship-type hulls].

ABS Rules for Building and Classing Floating Production Installations, published January 2024
This standard is implemented based on the following parts of the standard: Subsection 5A-3-4/5.3 – Plate Panels, Subsection 5A-3-4/7.3 – Rectangular Plates (Part 5A – Ship-Type Installations, Chapter 3 – Structural Design Requirements, Section 4 – Total Strength Assessment.
The requirements contained in these Rules are for design, construction, and survey after construction of the floating installation (including hull structure, equipment, and marine machinery), the position mooring system, and the hydrocarbon production facilities.
Floating installations of the ship-type, column-stabilized-type, tension leg platforms, and spar installations are included, as well as existing vessels converted to FPIs.
The requirements for optional notations for disconnectable floating installations, dynamic positioning systems, and import/export systems are also provided.

Info on ABS Standards
ABS Rules & Guides were developed by the American Bureau of Shipping (ABS) – an American maritime classification society established in 1862.
ABS was first chartered in New York in 1862 as the American Shipmasters’ Association (ASA) to certify qualified ship captains, or shipmasters, for safe ship operations during the Civil War.
ABS Rules & Guides form the basis for assessing the design and construction of new vessels and the integrity of existing vessels and marine structures.
The primary responsibility of ABS as a classification society is to verify that ABS-classed ships and marine structures comply with the established ABS Rules for design, construction, and periodic survey.
ABS also develops standards for the design, construction, and operational maintenance of offshore drilling and production units and for gas carriers of all types.
These standards cover mobile offshore drilling units (such as jack-up rigs, semisubmersible rigs, and drillships), floating offshore production installations (spars, tension leg platforms, semisubmersibles, and FPSOs/FSOs), fixed offshore structures, pipelines, risers, and single point moorings.
ABS was responsible for classing the first mobile offshore drilling unit, the first production spar, the first semisubmersible offshore wind turbine, and the first offshore support vessel in the Gulf of Mexico to use hybrid power.
