The most used and recognized offshore pipeline standard in the world has been updated to reflect the latest pipeline research and developments by DNV GL, and other leading industry players. The standard, previously called DNV-OS-F101 is now renamed DNVGL-ST-F101.
The new revision reflects the conclusions of joint industry projects (JIPs) by DNV GL and other leading industry players such as DNV GL’s JIP providing guidance for installation of rigid and flexible pipes, umbilicals and power cables.
DNVGL-ST-F101 now also incorporates input from a JIP on pipe-in-pipe (PiP) systems, which explored challenges related to existing PiP systems and shortcomings of current design standards related to PiP systems.
A number of requirements related to linepipe fabrication, welding and NDT have been updated to reflect advanced technologies, based on hands-on experience from DNV GL’s 14 laboratories and numerous field inspectors.
DNV GL’s JIP on subsea repair (DNVGL-RP-F113), which aimed to reduce the time and cost spent on the design and execution of pipeline repairs and a JIP on pre-commissioning of submarine pipelines (DNVGL-RP-F115) are also referred and partially implemented to ensure consistency.
