Why Choose SDC Verifier for API Compliance

open benchmarks to verify design

Dual Method Support

Run both LRFD (1993) and WSD (2007) checks — fully integrated and up to date.

Joint & Member Verification

Automate axial, bending, and weld strength checks for tubular joints and beams.

Real Offshore Logic

Account for load transfer, overlapping braces, resistance coefficients, and joint types (K, TY, X).

Clear Geometric Recognition

Joint Finder auto-detects brace and chord configurations, even with edge-case geometry.

Combine with AISC

Use AISC for non-tubular shapes and API for tubular members in a single workflow.

Audit-Ready Reports

Export all calculations with criteria plots, formulas, and cross-referenced IDs in one click.

About Standard

he American Petroleum Institute (API) sets globally recognized standards for the oil and gas industry, with a strong focus on offshore structural integrity and safety.

API RP 2A-LRFD (1993) This Load and Resistance Factor Design standard defines structural requirements for steel cylindrical elements and joints used in fixed offshore platforms. SDC Verifier implements Sections D (Cylindrical Members) and E (Connections), supporting joint classification (K, TY, X), load transfer, and overlap checks.

API RP 2A-WSD (2007) This Working Stress Design standard offers an alternative method for planning and constructing fixed offshore structures. SDC Verifier supports member and joint checks with Stress Increase Factors for different design conditions (Normal, Survival, Accidental).

Both standards are tailored for circular tube calculations and can be used with AISC standards to cover non-tubular elements. API checks are fully automated inside SDC Verifier and support complex geometries, brace interactions, and resistance calibration for safe offshore design.

Automate API Checks with SDC Verifier

Run LRFD and WSD checks for offshore tubular structures directly inside your FEA model.
Classify joints, verify beam members, and generate reports — no spreadsheets needed.
