TechnipFMC Receives First DNV DDV Notation


In a sign of increasing digitalisation in the offshore sector, DNV has awarded TechnipFMC its first class notation for Data Driven Verification (DDV) of dynamic positioning (DP) systems, reports Riviera.

Under the new DDV notation, the class society also awarded an approval in principle to Kongsberg Maritime’s dynamic positioning digital survey. This software system was used in the data-driven verification process for the DP systems that have been tested on board TechnipFMC’s 2014-built construction support and pipelay vessel Deep Star.

Offshore support vessels use DP systems for accurate manoeuvring, maintaining a fixed position or for track keeping (pipe and cable laying). These systems are subject to class verification, which normally requires a surveyor to be physically on board the vessel to witness the DP system testing and collect the relevant data for assessment by the classification society.

With the DDV class notation, the DP system can now be tested on board more conveniently with the support of the crew and without the need for a surveyor to physically attend. The use of a digital system enables the crew to run test activities and automatically harvest secure and reliable data on the vessel’s behaviour. This data can then be verified by the surveyor using a digital playback application.

Official statement

“We are proud to be the first company in the world to have been awarded the DDV Class notation for dynamic positioning systems,” said TechnipFMC OneFleet vice president David Jousset. “With this notation, the TechnipFMC vessel Deep Star can perform annual DP trials remotely with increased flexibility in planning, improved consistency, and increased transparent data sharing. This is a significant step in leveraging new capabilities in the digital space and bringing added value to our clients through greater efficiency and improved fleet utilisation.”

TechnipFMC is looking to scale this approach to its entire fleet

Kongsberg Maritime digital applications product manager Erik Korssjøen said, “This is a big step towards transforming the industry in a digitalised way.”

DNV Maritime special ships segment director Arnstein Eknes added, “Innovative digital systems are propelling the industry forward, enabling more efficient processes and deeper insights. The lessons we learn from developing and using these new systems are making class processes smoother, giving greater flexibility to owners, operators and most importantly crews. While at the same time, we are building data sets that are reliable and unlock value across the industry.”   

The DDV notation enables secure and tamper-free data harvesting to be performed by the crew without surveyors being present on board. Compared with traditional paper-based test reports, the body of evidence represents an accurate and detailed documentation of test activities, which can be revisited for as long as the data is stored. The notation covers several different verification methods, including self-verifying systems and digital twins.
