MOL, DSME test cryo-powered regas system for FSRU

Japan’s Mitsui OSK Lines (MOL) and Korea’s Daewoo Shipbuilding & Marine Engineering (DSME) have successfully carried out the demonstration test of the cryo-powered regasification system for floating storage and regasification unit (FSRU) at latter’s Okpo shipyard, the companies said on August 17.

“In the past, LNG's cold energy had not been utilised in FSRUs and was released. By installing the cryo-powered regas system, such cold energy will be transferred to another heating medium, and the generated steam will be sent to a turbine to generate electricity, which results in reducing FSRU's fuel consumption and CO₂ emissions,” the companies said.

A small-scale version of the regas system was built by DSME. The turbine generator used in this system was designed and constructed by Mitsubishi Heavy Industries Marine Machinery & Equipment Co.

“Through this test, MOL and DSME verified that the system could successfully generate electricity up to its rated capacity,” the companies said. “The result of this demonstration test confirms that through the utilisation of the cryo-powered regas system, fuel consumption and CO₂ emissions of new generation FSRUs can be reduced by 50% at maximum rated regas flow rate compared to conventional existing FSRUs.”

The cryo-powered regas system is ready for implementation in actual FSRU projects. MOL is already in discussions with multiple potential users, the companies said.
