DNV Awards First Class Rating and AiP for DDV of DP
DNV has awarded the ship’s owner, TechnipFMC, its First Class Rating for Data Driven Verification (DDV) of Dynamic Positioning (DP) Systems. Additionally, Kongsberg Maritime’s Dynamic Positioning Digital Survey (DPDS) received an Approval in Principle (AiP) under the DDV rating and was the software system used in the data-driven verification process for the DP systems that were tested. aboard Deep Star.
Dynamic positioning systems are used by offshore vessels for precise maneuvering, maintaining a fixed position or for tracking (laying pipes/cables). These systems require classification which is normally carried out via onboard inspections where the surveyor witnesses the testing of the DP system and collects the relevant data for evaluation by the classification society.
“We are proud to be the first company in the world to receive the DDV Class rating for Dynamic Positioning Systems,” said David Jousset, Vice President OneFleet at TechnipFMC. “With this rating, the TechnipFMC Deep Star vessel can conduct annual DP trials remotely with increased scheduling flexibility, improved consistency, and increased transparent data sharing. This is an important step in harnessing new capabilities in the digital space and adding value to our customers through greater efficiency and better fleet utilization. TechnipFMC plans to extend this approach to its entire fleet in the coming months.
“It has been a long journey to get to this stage of the DPDS deployment, and we are pleased to have such a forward-thinking shipowner and class association with us on the process,” said Erik Korssjøen, Director of produces Digital Applications at Kongsberg Maritime. “It is certainly a big step towards transforming the industry in a truly digitized way. We are delighted that ship owners are reaping the tremendous benefits of using DPDS.
With DDV class rating, DP system testing can now be done on board more easily with crew support and without a surveyor needing to be physically present. The use of a digital system allows the crew to carry out test activities and automatically collect secure and reliable data on the behavior of the vessel. This data can then be verified by the surveyor using a digital reader application.
“Innovative digital systems are driving the industry forward, enabling more efficient processes and deeper insights,” says Arnstein Eknes, Segment Manager – Special Vessels, DNV Maritime. “At DNV, we are very pleased to partner with TechnipFMC and Kongsberg Maritime to show the industry how we can begin to realize these gains. The lessons we learn from the development and use of these new systems make class processes smoother, providing greater flexibility for owners, operators and, most importantly, crews. At the same time, we are building trusted datasets and unlocking value across the industry. »
The DDV Class Notation defines requirements for the collection, processing and delivery of collected data to ensure the quality of that data for use in a class assessment. This means that for the systems specified, the verified data can be used in the certification and classification of these systems in maritime and offshore vessels.
The notation allows the crew to perform secure and tamper-proof data collection without surveyors being present on board. Compared to traditional paper-based test reports, the evidence set represents an accurate and detailed documentation of test activities, which can be revisited as long as the data is stored. The scoring covers several different verification methods, including self-verification systems and digital twins.
An Approval in Principle (AiP) is an independent assessment of a concept within an agreed framework, confirming that the design is feasible and no significant impediments exist to prevent the concept from being realized.
