Sep 2004 - Aug 2006
• Worked as acting Operation Manager and officiated as Plant manager. • Annual Operations budgeting and complete water and fuel Management of site. • Biggest challenge at this site is raw water quality – there is intrusion of seawater in river stream between December and March. This caused condenser tube failure in year 2003-04. This year we could able to manage to maintain water salinity to a minimum level by taking water in predetermined time using tide chart. Started using new chemical to cover this high stressed water condition. • Changed most of the chemicals and finalized Nalco contract for complete water treatment. Also reduced treatment chemical cost by 30% in a year. • Chemicals were changed for safe handling and new chemical SMS are documented. • Documented SOPs and qualification book for BOP – including WTP, Fuel handling, air compressor, etc. • To solve the water salinity problem specified above proposed for variable frequency drive SWRO at the upstream to present RO and going to install it by next year. • Actively involved in safety and environmental related matters. • Additionally taking part in redesigning GT inlet air filters and involved in day to day operational activities record monitoring, record logging, helped in making software for e-recording, etc. • Made excel base site specific software for chemical reporting, water and fuel consumption and inventory control for bulk chemicals. And with the help of software specialist trying to develop it in VISUAL-BASIC program for elogging and reporting. • Fuel procurement and fuel management and looking for adding up LNG facility. • Fuel inventory management based on fuel price forecast to reduce losses.
