DNV greenlights MISC and SHI’s floating CCS concept

DNV has approved in principle a prototype of a floating carbon storage injection unit developed by Malaysia's MISC and South Korea's Samsung Heavy Industries (SHI).

MISC explained that the floating facility will temporarily store captured carbon dioxide (CO2) onboard, then transport and inject it into depleted oil and gas fields offshore to permanently store it.

It will have a CO2 storage capacity of up to 100,000 cbm (187,000 mt) and a CO2 injection capacity of around 5 million mt/year, according to MISC.

SHI and MISC are also working on adding a CO2 liquefaction facility to the unit to improve its "utility and practicality."

The technology will be a viable alternative to the traditional pipeline method and its "scalability and storage capabilities" will enable it to be used for maritime CCS projects, MISC noted.

Meanwhile, GJ Yoon, SHI’s head of engineering management, said that SHI is working on multiple concepts to address the “era of low carbon.” This includes CO2 carriers, he confirmed.

“Whereas [liquefied CO2] LCO2 Carriers focus on transportation, FCSU can act as Offshore Terminal and [is] capable of injecting CO2 into subsea wells with Topside facility,” Yoon added.
