Hyundai Heavy Industries (HHI) has developed a Digital Health Management system (DHM) for IMO Type-B LNG fuel tanks, which has been granted Approval in Principal (AIP) by Lloyds Register (LR) as being ‘Digital Twin READY’.
This AIP was achieved through a cooperative joint development project involving HHI, LR and the Liberian Registry (LISCR) as flag state. The purpose of the new system is to ensure the structural safety of LNG fuel tanks, and to increase the operational efficiency of ships.
The award of the AIP forms the basis for the application of the digital twin system, opening up the possibility of operating and maintaining fuel tanks based on digital data while complying with the requirements of the classification society and flag state.
“We were honoured to be able to participate as flag state, and HHI’s innovative concept with digital twin to support a Digital Health Management system providing fault detection and diagnostics of an LNG Type B tank and allowing real-time condition monitoring and assessment of the gas containment tank is a ground-breaking approach to enhance the effectiveness of maintenance and compliance with classification and statutory requirements,” said Thomas Klenum, Senior Vice President of Maritime Operations at the Liberian International Ship and Corporate Registry (LISCR).
