Currently, in SDC Verifier, it is possible to perform code checking according to API RP 2A-LRFD (1st, 1993) – Planning, Designing, and Constructing Fixed Offshore Platforms – Load and Resistance Factor Design and API RP 2A-WSD (21st, 2007) – Planning, Designing, and Constructing Fixed Offshore Platforms — Working Stress Design.

You can perform Joint Checks and Beam Member Check according to API RP 2A-LRFD and API RP 2A-WSD in SDC Verifier. Standards support calculations for circular tubes only.

Recommended Practice for Planning, Designing, and Constructing Fixed Offshore Platforms – Load and Resistance Factor Design (API RP 2A-LRFD (1st, July 1993))

This “Recommended Practice for Planning, Designing, and Constructing Fixed Offshore Platforms — Load and Resistance Factor Design” (LRFD) includes the engineering design principles and good practices that have been the basis of the API RP2A working strength design (WSD) recommended practice, now in its 20th Edition. Using reliability-based calibration, the LRFD requirements were created from the WSD provisions.

This recommended practice is supported by solid engineering principles, extensive testing, and real-world application knowledge. No particular advice is made that cannot be carried out using the methods and tools that are currently in use. In every situation, the protection of the workforce, adherence to current laws, and pollution control are taken into account.

This standard is applied to the cylindrical members with the Thickness ≥ 6mm, ratio D / t < 300 and Yield < 414 MPa.

Two sections of this recommended practice implemented in SDC Verifier: Section D. Cylindrical Member Design (D.2 Cylindrical Members Under Tension, Compression, Bending, Shear or Hydrostatic Pressure, D.3 Cylindrical Members Under Combined Loads) and Section E. Connections (E.1 Connection of Tension and Compression Members, E.2 Tubular Joints). Read the help article on implementation of API RP 2A-LRFD in SDC Verifier.

Recommended Practice for Planning, Designing and Constructing Fixed Offshore Platforms-Working Stress Design API RP 2A-WSD (21st, 2007)

This Recommended Practice for Planning, Designing, and Constructing Fixed Offshore Platforms contains engineering design principles and good practices that have evolved during the development of offshore oil resources. Since excellent engineering is the foundation of good practice, this suggested practice consists mostly of solid engineering advice. No particular advice is made that cannot be carried out using the methods and tools that are currently in use. In every situation, the protection of the workforce, adherence to rules already in place, and prevention of water body pollution are taken into account.

Info on API Standards

API standards are developed under API’s (American Petroleum Institute) American National Standards Institute (ANSI) accredited process. API is the worldwide leading standards setting body for the oil and natural gas industry. Since 1919 API has issued nearly 700 consensus standards governing all segments of the oil and gas industry. These include standards, guidelines, and recommended practices regarding safety, equipment, operations, effective water management, spill prevention and environmental protection. Many API standards and practices are incorporated into both federal and state oil and natural gas regulations, and they are the most widely cited petroleum industry standards by international regulators.
