Mitsui OSK Lines (MOL) and Daewoo Shipbuilding & Marine Engineering (DSME) have carried out a demonstration test of an FSRU cryo-powered regas (CPR) system.
This test was carried out at DSME's Okpo shipyard.
FSRUs regasify -160 deg C LNG through heat exchange.
Previously, LNG's cold energy had not been utilised in FSRUs and was released. By installing a CPR system, cold energy will be transferred to another heating medium, and the generated steam will be sent to a turbine to generate electricity. As a result, the FSRU's fuel consumption and CO2 emissions will be reduced.
A small-scale version of the system was assembled in DSME's R&D premises. The turbine generator used in this system was designed and constructed by Mitsubishi Heavy Industries Marine Machinery & Equipment specifically for the system.
Through this test, MOL and DSME verified that the system could successfully generate electricity up to its rated capacity. The results confirmed that through the use of a CPR, 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 CPR is now ready for implementation in FSRU projects and MOL said that it was already in discussions with multiple potential users.
