Classification society DNV GL, Kongsberg Maritime and Subsea 7 have efficiently concluded the pilot testing of Kongsberg Maritime’s (KM) DP Digital Survey (KMDS) software on board the Subsea 7 vessel Seven Kestrel. The pilot examined using a distant digital verification instrument for testing dynamic positioning (DP) methods as a part of DNV GL’s D-Class venture.
In March 2019, DNV GL rolled out the primary fleet-wide distant survey scheme for some inspections within the classification trade. This implies that for some surveys, a DNV GL surveyor isn’t required to journey to the vessel, however as a substitute, enter offered by the client and crew is used to reveal compliance. This saves journey prices, ready time, and reduces vessel downtime. The scheme has been warmly greeted by each prospects and flag states.
Testing the dynamic positioning (DP) methods on vessels in operation has additionally historically required a surveyor go to, usually alongside DP failure mode and results analyses (FMEA) consultants and gear vendor consultants, to witness verification trials. Coordinating and conducting these exams with a number of companions can lead to a vessel being taken out of operation for a number of days.
“The digital survey is a chance to ship on our DP verification focus areas by capturing information from what are at the moment seen as routine occasions, enabling us to make use of these recordings as verification of our asset efficiency. This expertise additionally offers us the next information high quality than we at the moment obtain by handbook trials and offers us a everlasting tamper proof recording of the occasion. The check methodology used inside the software additionally empowers the crew to take possession of the system and provides them larger confidence within the DP system setup onboard their vessel. This will present us with a extra sturdy survey and we see this as a lead into larger security by familiarization inside our fleet,” stated Bryce Heslop, Marine Technical Manager at Subsea 7.
To attempt to scale back the burden of verifying DP methods on its prospects, by enhancing effectivity whereas sustaining effectiveness and security requirements, DNV GL launched the Data Smart Classification or D-Class Project in 2017. It is designed to judge and work towards the acceptance of latest strategies and expertise for the verification of DP methods.
As a part of the D-Class venture, DNV GL initiated a pilot to look at the opportunity of utilizing Kongsberg Maritime’s DP Digital Survey instrument in annual verification trials. The pilot used the instrument on board Subsea 7’s diving assist vessel Seven Kestrel and lined each class survey necessities and normal worldwide trade exams. The instrument takes information instantly from a vessel’s management methods and transmits this to a safe cloud, the place it’s out there for evaluation by skilled verifiers, class, and distributors.
“The KM-DPDS software provides our prospects a instrument that may doubtlessly scale back their OPEX for every DP vessel and enhance the vessel’s uptime, as the person DP trial exams might be executed throughout non-productive time. The competence of DP key personnel is enhanced as properly,” stated Eivind Alling, V.P. of digital efficiency at Kongsberg Maritime. “The collaboration with DNV GL and Subsea 7 has been of paramount significance to develop standards for the digitalization of the Annual DP trial program, based mostly on IMO MSC/Circ.1580, the DNV GL DP class notation and IMCA M 190 steerage doc. The profitable completion of the pilot paves the best way for an software of a DNV GL Approval in Principal for the KM-DPDS answer.”
“With this pilot, we now have proof-of-concept for utilizing the KMDS software for verification of DP methods. This expertise has the potential to supply safe and tamper-proof assortment of system-generated information, which can be utilized as proof for performing goal distant workplace evaluation by class. The information collected can even kind a considerably improved physique of proof for documenting check outcomes, which can assist to extend…
