DNV GL’s guideline moves to trash excess subsea paperwork

Offshore and maritime classification society DNV GL has launched a guideline which “trashes unnecessary subsea documentation.”

According to DNV GL, customer-case shows potential for a 40% reduction in engineering hours on subsea paperwork, and up to 80% less documentation.

The guideline “Technical documentation for subsea projects” details a required minimum set of documentation transferred between E&P companies, operators and contractors for the construction, procurement and operation of a field. The outcome will reduce the volume and variety of documentation exchanged between the parties in a project thereby making project execution more cost effective, DNV GL says..

According to a contractor in the JIP, subsea documentation increased by a factor of four between 2012 and 20151. Previously, a contractor in a typical subsea project would deliver around 10,000 documents with each one averaging three revisions, resulting in up to 30,000 transactions between two actors. Today, projects can deliver 40,000 documents with three revisions resulting in 120,000 transactions. Handling time has also doubled per revision. A big project may require a contractor to have 25 people just on document control, DNV GL reveals.

“We like solid documentation in DNV GL, but this massive explosion in paper hasn’t tangibly improved performance, safety or environmental impact – it’s just escalated costs without adding value,” says Bente Helén Leinum, Project Manager, DNV GL – Oil & Gas.

“A benchmarking exercise by one JIP participant showed that adoption of the RP could deliver a 42% potential reduction in engineering hours. The savings comes from reduced reviews by reusing documents, having more standardized documents and avoiding unnecessary reviews of non-critical documents. Another supplier estimates that the potential cut in documentation can be as high as 75-80% through increased use of standardized documents,” continues Leinum.

Jan Ragnvald Torsvik, lead engineer of Life Cycle Information at Statoil and co-chairman of the project, said“All JIP partners have invested considerable time and the outcome is a fantastic achievement that will dramatically cut waste in handling technical information in projects. We have already learned that this standard’s approach in utilizing package specific requirements has a positive impact on standardization, efficiency and quality. We are already seeing the benefits of implementing a draft version of the RP in Statoil’s Johan Sverdrup project last year.”

“The RP encourages more reuse of subsea documentation and will deliver more predictability throughout the value chain. It provides clear expectations for all parties involved, and duplications, misunderstandings and unnecessary work can be avoided,” says Tommy Lien, Senior LCI Process Coordinator, Aker Solutions.

JIP partners were Aker Solutions, Brightport, Centrica Energi, DEA Norge, Det norske oljeselskap, DNV GL, ENI Norge, GCE Subsea, FMC Technologies, GDF SUEZ E&P Norge, Kongsberg Oil & Gas Technologies, Lundin Norway, Oceaneering, OneSubsea, , Statoil , Subsea 7, Subsea Valley and SUNCOR Energy Norge.
