API History
  • 1919 API founded as non-profit national trade
    association, New York City
  • 1980s API relocates to Washington, DC
  • 1995 API Dallas Standards Office relocates to
    Washington, DC
  • 2007 Opened first of 3 planned international
    offices in Beijing, China
  • 2011 Singapore and Dubai, UAE offices opened

Background on API Standards Program
  • The API Standardization Department was formed in
    1923, with the first API standard published the
    following year on drilling threads.
  • All industry segments now active in
  • Exploration and Production
  • Pipeline Transportation
  • Refining
  • Marketing

API Standards
  • API now publishes more than 600 technical
    standards covering all aspects of the oil and
    natural gas industry
  • Foundation of Self Supporting Programs
  • Basis for Worldwide Operations
  • Core of Institutes Technical Authority

Standards Development Process
  • The API Standards program is accredited by the
    American National Standards Institute (ANSI)
    the program was reaccredited by ANSI in Oct. 2011
    following a 2010 audit. - Openness, Balance,
    Consensus, Due Process - Regular program audits
    (conducted by ANSI)
  • Transparent process (anyone can comment on any
    document in process) - All comments must be

Standards Development Process
  • Developed by consensus (does not mean unanimity)
  • Committee balance between users/owner operators,
    manufacturers and contractors/consultants
  • Standards developed using ANSI approved API
    Standards Development Procedures (available
    on-line at www.api.org)
  • API corporate membership is not a requirement for
    participation on API standardization committees.
  • Support from your management to participate is.

Use of API Standards
  • De facto international standards
  • Adoption by reference common by State and Federal
    agencies BSEE, USCG, DOT, OSHA and EPA
  • API does not promote adoption - prefer voluntary
  • Written for flexibility as performance based

API Standards Committee Structure
Committee on Standardization of Oilfield
Equipment Materials
Committee on Petroleum Measurement
Committee on Refinery Equipment
  • Marketing/Aviation
  • Pipeline Transportation
  • Safety Fire Protection

To support the Standards there are Certification
programs API Monogram Program, Individual
Certification Programs and others, www.api.org
- Certification Programs
AST Standards
  • API publishes over 70 standards, recommended
    practices, and bulletins covering various aspects
    of tank operations
  • Design Construction
  • Inspection
  • Measurement and emissions
  • Safety Fire Protection - Safe Entry, Overfill
  • Environmental - Leak detection, Release
    Prevention, Emissions
  • For committee access
  • mycommittees.api.org/standards/cre/scast/default.a
  • Next Standards meeting April 22 25, 2013
  • www.api.org/events-and-training/calendar-of-events

AST Standards - History
  • From 653 - Annex A Background on Past Editions
    of API Welded Storage Tank Standards
  • API published a specification for welded steel
    storage tanks in July 1936 entitled API Standard
    12C, All-Welded Oil Storage Tanks. Fifteen
    editions and seven supplements to API 12C were
    published between 1936 and 1958.
  • API 12C was replaced by API Standard 650, Welded
    Tanks for Oil Storage in December 1961 11
    editions and 22 supplements, revisions or addenda
    to API 650 have been issued since.
