I am looking for information on the 12V26A engine other then what is in the Wartsilla website.
Also if anyone could recomend any good books on HFO operation etc.
Thanks for the help once again!

Please advise if you are changing to HFO operation ? Or if you are already running HFO and want more information with regards to HFO maintenance intervals ?

I have taken a position on a vessel that is running both MGO and IFO, and am looking for any information to assist me in getting up to speed on the fuel change over and the engine.

I fell over this short pdf from 2006 that give a brief introduction..

Please be advised that a lot of the interest is going in a other direction. How to comply with light fuels in specific areas and then return to HFO operation when not in SECA areas. We experience a lot of seized plunger and barrels from changes. A solution have been to carry 01 set HFO elements and 01 set MDO elements and simply change completely. But again - very dependent of area of operation
