DNV GL Releases New Guidelines for Submarine Pipelines

DNV GL has released the DNVGL-RP-F114, which provides holistic guidance and recommendations within a geotechnical framework for pipe-soil interaction assessments.

“Geotechnical competence is required to understand the complex soil behaviour close to the pipe during installation and operational conditions, in addition to managing the inevitable uncertainties related to limited soil data and to simplifications in the engineering models,” Jens Bergan-Haavik, Senior Geotechnical Engineer, DNV GL – Oil & Gas, said. “The pipe-soil RP highlights the value of geotechnical input in projects to ensure robust pipeline design solutions. The RP also provides recommendations on how to safely avoid over-conservatism through specification of state-of-the-art laboratory tests.”

DNVGL-RP-F114 replaces the company’s following pipe-soil interaction recommended practices:

  • DNVGL-RP-F105 Free spanning pipelines
  • DNVGL-RP-F107 Risk assessment of pipeline protection
  • DNVGL-RP-F109 On-bottom stability design of submarine pipelines
  • DNVGL-RP-F110 Global buckling of submarine pipelines
  • DNVGL-RP-F111 Interference between trawl gear and pipelines
  • DNVGL-RP-F113 Pipeline subsea repair.

“27% of senior players in the sector believe there will be a significant global increase in the approval of new offshore oil and gas pipeline projects globally over the three years,” Cathrine Torp, Communication Director, DNV GL – Oil & Gas, said. “As increased knowledge is the best cure for managing uncertainties, this new RP will support pipeline projects with the insights they need for safe and efficient installations and operations.”
