McDermott, Daewoo Shipbuilding & Marine Engineering to study large liquid hydrogen carrier

US contractor McDermott’s storage business line CB&I and South Korea’s Daewoo Shipbuilding & Marine Engineering plan to carry out a feasibility study for a large liquid hydrogen (LH2) carrier, including an LH2 storage tank design.

CB&I will evaluate its LH2 storage tank design for ocean-going ships while Daewoo will investigate and develop the vessel’s general design to install the LH2 storage tank.

The feasibility study work is expected to contribute to the future design of a large-scale LH2 carrier.

The US contractor’s spheres can store LH2 at temperatures of minus 252.8 minus degrees Celsius, and the company is nearing completion of the world’s largest LH2 sphere in Cape Canaveral, Florida.

McDermott said that the ability to transport large quantities of hydrogen across oceans is becoming increasingly necessary to help countries such as South Korea to achieve carbon reduction goals in a hydrogen economy.

“The development of LH2 storage for ocean-bound vessels is essential to South Korea’s focus on a carbon-neutral environment,” said CB&I senior vice president Cesar Canals.

“Our expertise in designing and building field-erected pressure spheres for LH2 storage is a perfect combination with (Daewoo’s) technical excellence.”
