MOL AND DSME DEMONSTRATE SYSTEM TO HALVE FSRU CO2 EMISSIONS

MOL AND DSME DEMONSTRATE SYSTEM TO HALVE FSRU CO2 EMISSIONS

Tuesday, August 17, 2021 

Mitsui OSK Lines (MOL) and Daewoo Shipbuilding & Marine Engineering (DSME) have successfully carried out a demonstration of the Cryo-Powered Regas system for FSRU (Floating Storage and Regasification Units) at DSME's Okpo shipyard in Korea.

The role of an FSRU is to regasify -160°C liquified natural gas (LNG) through heat exchange. In the past, LNG's cold energy had not been utilised in FSRUs and was released. By installing the Cryo-Powered Regas (CPR) 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.

A small-scale version of the system was built in DSME's R&D premises. The turbine generator used in this system was designed and constructed by Mitsubishi Heavy Industries Marine Machinery & Equipment Co specifically for the CPR System. Through this test, MOL and DSME verified that the system could successfully generate electricity up to its rated capacity. The result of this demonstration test confirms that through the utilisation of the CPR 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.

Introducing fuel efficient FSRUs with lower CO2 emission rates to the market is one of the initiatives that MOL is pursuing towards the achievement of MOL Group's Environmental Vision 2.1. The CPR System is said to be ready for implementation in actual FSRU projects. MOL is already in discussions with potential users and is confident in further promoting this system.
