Advantages o

Minimum land requirement of about 20 acres for offshore facilities. Foundation is not required for main plant hence reduced construction time.

Black start facility for plant start up is available.

Main plant systems supplied by reputed OEM’s like GE and ABB.

OTSG has dry running capability up to 560 Deg C which is suitable to operate in a simple-cycle mode.

Once Through Steam Generator is quick to adjust during sudden fluctuation in load.
