DNV GL announces new recommended practice for subsea forgings


Steel forgings are essential building blocks for subsea components, but tailor-made solutions to meet end-users’ specific requirements have caused long delivery times. A joint industry project (JIP), led by DNV GL, has now taken the next step in subsea standardization by harmonizing requirements for quality management of forgings. The recommended practice (RP) ‘Steel forgings for subsea applications – quality management requirements,' DNVGL-RP-B202, will enable delivery of high quality forgings at reduced delivery times and cost.

Complementing the RP ’Steel forgings for subsea applications’ (DNVGL-RP-0034), which harmonizes the technical requirements, the new guideline DNVGL-RP-B202 provides a unified approach to the qualification of manufacturers and the manufacturing procedure, and to perform production oversight.

According to DNV GL’s seventh annual benchmark study, Short-term agility, long-term resilience, subsea technology is highest ranked area globally for conducting R&D among emerging technologies in 2017. Also, standardization efforts are on the rise to remove complexities: Two thirds of respondents say their organization will seek greater standardization of tools and processes in 2017.

The following companies have been part of developing the RP in phase two of the JIP: Aker Solutions, BP International Limited, Brück, Celsa, Chevron, ConocoPhillips, Det Norske, Dril-Quip, Ellwood Group, Eni, Exxon Mobil, Franchini Acciai, Frisa, GE, OneSubsea, Petrobras, Ringmill, Scana Subsea, Statoil, TechnipFMC and Total.
