HD Hyundai Heavy Industries succeeded in building ammonia propulsion lines for the first time in the world.

HD Hyundai Heavy Industries held a naming ceremony for two medium-sized gas carriers equipped with dual fuel (DF) engines at its Ulsan shipyard on the 9th.

More than 70 officials and executives attended the event, including President Joo Won-ho, the head of HD Hyundai Heavy Industries' ship and heavy ship business, Chairman Nicholas Saberis Xmar, and Belgian Ambassador to Korea Bruno Jans.

Two ships were named 'Ant-Verpen' and 'Arlong', respectively, after the Belgian city. HD Hyundai Heavy Industries will be delivered to the shipowner in May and late July, respectively, after completion, on lines 1 and 2 of the four ammonia-powered medium-sized gas carriers won by Xmar LPG France, a subsidiary of the Belgian shipping company Xmar in 2023 and 2024.

With specifications of 190m long, 30.4m wide and 18.8m high, these ships are equipped with three cargo windows designed and manufactured by HD Hyundai Heavy Industries with their own technology to stably transport liquefied gas cargo such as ammonia and liquefied petroleum gas (LPG).

These ships are equipped with a shaft generator that generates power using the rotating shaft of the propulsion engine and a selective catalytic reduction device to further enhance eco-friendliness.

In particular, it has secured the highest level of safety by applying unique disaster prevention technologies and systems such as the Ammonia Gas Detector and the Ammonia Purge Recovery Unit that can check ammonia leakage in real time.

Ammonia (NH3), an eco-friendly carbon-free fuel, can be stored in a pressure tank (about 8 bar) or a low-temperature tank (-33°C) without cryogenic technology, and is 1.7 times more storage density than liquefied hydrogen (-253°C) in the same volume when liquefied, so it is considered suitable for large-scale long-distance transportation and storage of hydrogen.

"We will build the world's first ammonia propulsion ship and further solidify our leadership in the global eco-friendly ship market through continuous technological innovation in the future," said an HD Hyundai official who spoke to this newspaper by phone.
