(2) Light diesel oil
For a start-up, stop and maintenance.
The viscosity of Diesel oil shall be of 2.0 ~ 14 cSt at Engine inlet under the power
plant operating conditions.
1.4 Lubricating oil for engine
The lubrication oil of diesel should be selected from the recommended lubrication oil
list to be of HD (heavy type) Grade API-CD and SAE 40.
1.5 Cooling Water
The normal fresh water with inclusion of preservative is designed and employed for
design of cooling water system to prevent the rustiness and corrosion.
The water quality should conform to the following requirements:
Circulating Water of Engine

Click here to view the Drawings of 30MW HFO Container Type power plant in Indonesia 25/11 2013
We have some questions :
1. What is estimate cost for O & M ? ( US$ / KWH )
2. Delivery time 12-14 Moths is CIF Pontianak condition or COD? ( Commisioning & Delivery )
3. Estimate Weight including Countainer?
Here is the reply to your questions:
1. The rough O&M cost is about 2cent/kWh (to 8000 operation hours per year), which including labor and spare parts, not including fuel and lube oil. If less than 8000 hours per, then cost will be increased per kwh.
2. Our C& F delivery time is about 12-14 months, after the contract effectuated, we do not know the takeover time which affected by a lot of factors on site.
3. Payment : advance payment by T/T against bank guarantee, balance by L/C or T/T, if by deferred L/C then we can negotiate for more details such as confirmation bank, L/C issuing bank
4. Unit weight for containerized hfo gensets is about 48tons.
