MHN-Process Platform & Living Quarter project of ONGC with L&T Ltd
Location: Offshore
Value of the Project: USD 1 Billion
MHN process complex consists of existing MNW process platform, NA well cum process platform and proposed MNP process platform, MLQ living quarter platform and flare tripods MNF1 & MNF2. All the processing facilities i.e. fuel gas system, separation, produced water treatment, gas compression and dehydration, gas sweetening etc is installed on this platform. In addition there are testing facilities for testing of production coming from individual platforms.
