The Liberian International Ship and Corporate Registry (LISCR) on Monday (2 November) said Hyundai Heavy Industries (HHI) has developed a Digital Health Management system (DHM) for safety and operational efficiency of IMO Type-B liquified natural gas (LNG) fuel tanks.
The new and advanced system, an industry first, has achieved an Approval in Principle (AIP) for its “Digital Twin READY” from Class Society Lloyds Register (LR).
The purpose of this new system is to ensure the structural safety of the Type-B LNG fuel tanks, and to increase the operational efficiency of the ship.
“This AIP was achieved after very close cooperation between HHI, LR and the Liberian Registry,” said Thomas Klenum, Senior Vice President of Maritime Operations of LISCR.
“We were honored 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 allow real-time condition monitoring and assessment of the gas containment tank is a groundbreaking approach to enhance the effectiveness of maintenance and compliance with the classification and statutory requirements. HHI and LR were fantastic partners.”
LISCR noted that the AIP was awarded after a technical documentary review of the concept design for the structural DHM of the tanks was performed, and the basis of Verification, Validation, and Investigation Process was established, based on Hyundai Heavy Industries Group’s Integrated Smart Ship Solution (ISS) and experience of design cryogenic liquefied gas fuel tanks.
The award of AIP secured the basis for the application of the digital twin system, and presented the possibility of operating and maintaining fuel tanks in an efficient manner, while complying with the requirements of the classification society and flag State.
