Key details of the plant:

  • Year of built – The barge was originally commissioned in the year 2001 in Mangalore.
  • Maker – Gas Turbine (GE-USA) , Steam Turbine (Alstom)
  • Type – LM6000 PC sprint aero derivative gas turbine. Gas turbine Generator is open air-cooled, synchronous type and totally enclosed
  • It is a combined cycle plant
  • Alternator Description - two pole  air cooled generator with brushless excitation
  • Running hours / RPM/ Volt/ Hz – [~35,000 hours. Maintenance as per OEM schedule is adhered to. Power plant generates at 11kV and power is evacuated at 220kV @ 50Hz]
  • Plant is under preservation since April 2013. The barge was last started in Aug 2015
  • Keel laying was done in 2000. Initially it was run on Naphtha; Later it was modified to run on Natural gas.
  • The GTs have run an average of about 33000 Hrs. (28000 to 35,000 Hours). Major Overhaul is not for another 18000-15000 hours. (The routine maintenance as per OEM recommendation is done under LTSA)
  • Running hours after any modifications done - About 55000 hours.
  • Marine Survey Report on the Barge - The barge is under certification of ABS. Hence there is o separate survey done by us. However, few potential buyers have carried out the surveys on their own and were satisfied. We encourage the buyers to carry out the marine survey on their own.

 We are expecting a price of 102 Million USD, though the priority for us is a genuine and credible buyer.

We are open to discussions on price.

Benefits of Barge Mounted Power
Plant (1/2)

Capacity addition in one go

Single time mobilization &  vastly
reduced land requirement as compared to land based frame machines.

Can meet immediate power needs

Can Be modified to operate
on Liquid Fuel till such time gas is made available

The plant can be set up and commissioned in SC mode in 8 M and CC mode in 12 M

Benefits of Barge Mounted Power
Plant (2/2)

• Dry running capability of the OTSG with
Incoalloy tubes provides
• Open cycle operation
• Quick ramp up to 140 MW in about 45 minutes.
• Best suited for marine environment
• Compact quality power plant that will provide higher reliability and cheaper power.
• The choice and configuration of equipment especially the gas turbine on the barge ensure that
- The efficiency of the power plant will remain
close to its maximum efficiency
while operating over a wide range of
loads and can operate between
25 % to 100 % loads efficiently
- The lowest minimum safe and
sustained level of operation compared
to any land based configuration

- Plant can function as black start
facility in case of grid/system failure
the ramp up rates and shut
down rates for this facility are faster
than  most land based facilities

 - 1 no 53 MW rated output steam turbine and generator.

 7. Minimum onshore facilities with following major systems:

 - Switchyard for Power Evacuation, 415V MCC for DM Plant etc.

 - Fuel treatment and forwarding

 - Water Treatment Plant and DM plant

 - Fire Fighting System.

 · 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.
