HHI receives certification for digital twin fuel tank safety

This new and advanced system, an industry first, has achieved Approval in Principal (AIP) of its “Digital Twin READY” Type-B LNG fuel Tanks.

This AIP was achieved through close cooperation with the Liberian Registry (LISCR) as Flag State, and Lloyds Register (LR) as Class Society through JDP.

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.

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. These new developments by applying advanced technologies will lead to efficiencies that will benefit vessels on which they are fitted.

“This AIP was achieved after very close cooperation between HHI, LR and the Liberian Registry. 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 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,” said Thomas Klenum, Senior Vice President of Maritime Operations of the Liberian International Ship and Corporate Registry (LISCR)

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.
