At Gastech 2022, DNV awarded an Approval in Principle (AiP) to HHI Group for their innovative Hyundai Intelligent Digital Twin Ship (HiDTS) system.
he AiP confirms the software system HiDTS, which was developed specifically for 174,000 CBM LNG carriers, meets the requirements of DNV’s Data-Driven Verification (DDV) class notation of Power Management System (PMS) with the Digital Twin (DT) qualifier.
The HiDTS used in the DDV process was assured by DNV-RP-0513. With the DDV class notation, the testing of the PMS system can be performed via a digital twin more conveniently and extensively without a surveyor having to attend physically. Also, using a digital twin enables test run activities and automatically harvests secure and reliable data on the PMS’s behaviour. The surveyor can then verify this data using a digital playback application.
The DDV class notation sets the requirements for gathering, treating, and delivering collected data to ensure data quality in a class assessment. This means that for the specified systems, the verified data can be used in the certification and classification of those systems in maritime and offshore vessels.
The notation enables the crew to perform secure and tamper-free data harvesting. Compared to traditional paper-based test reports, the body of evidence represents accurate and detailed documentation of test activities, which can be revisited for as long as the data is stored. In addition, the notation covers several verification methods, including digital survey appliances and self-verifying systems.
