Provides minimum requirements and guidance for the design and installation of new piping systems on production platforms located offshore for the petroleum and natural gas industries. It covers piping systems up to 69000 kPa (gas) maximum, within temperature range limits for the materials meeting the requirements of ASME B31.3.
