DSME Installs First Hardened Steel LNG Fuel Tank on 24,000 TEU Newbuild

South Korea’s Daewoo Shipbuilding & Marine Engineering has loaded what it claims is the world’s first high manganese steel LNG fuel tank on a newbuild containership.

The rectangular tank was mounted inside a 24,000 TEU capacity containership under construction.

High manganese steel is known for its high impact strength and abrasion resistance. DSME says the ultra-hardened steel is advantageous for super-cooled LNG fuel tanks and cargo holds because of its strength to withstand sloshing during operation and there are also no shape limitations.

DSME says it has been developing the high manganese LNG fuel tank technology for over a decade through a joint research and development with South Korean steel-making company POSCO.

DMSE did not reveal the identity of the ship.

We’ll note that in December 2020, Hapag-Lloyd ordered six dual fuel LNG containerships with 23,500 capacity at DSME with deliveries planned in 2023. Hapag-Lloyd followed up with a second identical order in June 2021 with deliveries planned in 2024.
