Full title and description

Planning, Designing, and Constructing Fixed Offshore Platforms — Working Stress Design (API RP 2A‑WSD). 22nd Edition, originally published November 1, 2014; the 22nd edition was reaffirmed (R20) in 2020.

Abstract

This Recommended Practice provides guidance, criteria and procedures for the planning, design, fabrication, installation and inspection of fixed steel offshore platforms used for drilling, development, production and storage of hydrocarbons. It addresses structural design (tubular and non‑tubular members), joints, fatigue, foundations, material and welding requirements, fabrication and installation topics, and ancillary considerations required for safe platform construction and operation.

General information

• Status: Reaffirmed (R20) — 2020; maintained as the 22nd edition (status listed as current/reaffirmed by standards distributors).
• Publication date: November 1, 2014 (22nd edition).
• Publisher: American Petroleum Institute (API).
• ICS / categories: Offshore and petroleum industry — structural design, fixed offshore platforms, engineering practice.
• Edition / version: 22nd Edition (R20 — reaffirmed 2020).
• Number of pages: 324 pages.

Scope

Governs the recommended practice for planning, designing and constructing new fixed offshore platforms and for relocation of existing platforms in offshore hydrocarbon production areas. The document is intended to be used together with related API recommended practices for seismic, metocean, soil/foundation and integrity management where those subjects are handled by separate API documents.

Key topics and requirements

• Overall planning and design philosophy for fixed offshore platforms (WSD approach).
• Design criteria and procedures for structural systems, including load descriptions and combinations.
• Structural steel design for members and tubular joint strength provisions.
• Fatigue assessment methods and detail design to control fatigue damage.
• Foundation and soil interaction guidance for fixed platforms.
• Material, welding, fabrication, and installation requirements and quality control.
• Inspection, testing, accidental loading and provisions for reuse or relocation.
• Informative annexes and commentary to aid application and cross‑reference changes from previous editions.

Typical use and users

Used by offshore structural engineers, platform designers, fabrication yards, construction/installation contractors, project managers, asset owners/operators, technical consultants and regulators involved in fixed platform projects and assessments. Practitioners use the RP for new design, relocation projects and as a baseline for structural reviews and inspections.

Related standards

Closely associated API documents and other standards include API RP 2A‑LRFD (load and resistance factor design alternative for fixed platforms), API 2SIM (structural integrity management / fitness‑for‑purpose), API RP 2EQ (seismic design procedures), API 2MET and API 2GEO (metocean and geotechnical guidance), and ISO 19902 where applicable; the RP historically references AISC provisions for non‑tubular members.
