Hyundai Heavy develops Digital Health Management system

A Digital Health Management System (DHM) for the protection and operational efficiency of IMO Type-B LNG fuel tanks has been developed by Hyundai Heavy Industries (HHI).


This new industry-first system has achieved Principal Approval (AIP) for its "Digital Twin READY" Type-B LNG fuel tanks.

Via collaboration with the Liberian Registry (LISCR) as Flag State, and Lloyds Register (LR) as Class Society through JDP, this AIP was achieved. The aim of this new system is to ensure that the Type-B LNG fuel tanks are structurally secure and to improve the ship's operational performance.

Based on Hyundai Heavy Industries Group's Integrated Smart Ship Solution (ISS) and experience in the design of cryogenic liquefied gas fuel tanks, the AIP was awarded after a technical documentary analysis of the concept design for the structural DHM of the tanks was conducted and the basis of the verification, validation and investigation process was developed.

“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," stated Thomas Klenum, Senior Vice President of Maritime Operations of the Liberian International Ship and Corporate Registry (LISCR).

The AIP award secured a basis for the application of the digital twin system and provided an opportunity for the efficient repair and control of fuel tanks, thus meeting the requirements of the classification society and the flag state. Through the implementation of advanced technology, these new developments will lead to efficiencies that will support the vessels on which they are mounted.
