Here's a question for those of you that have had the pleasure of maintaining an oil record book.
We have two tanks that are recorded as sludge tanks and are therefore recorded in the oil record book when any transfers are made, such as to an incinerator or from another tank registered as holding sludge to one of these sludge tanks. However, my question is about something in the guidance that is in my opinion not overly clear.
One of the tanks has all of the engine room drains leading to it, so we are talking settling/service tank water drains and various oil drains round the engine room. Now, since the oil record book states that I only need to log waste oil collections that are PUMPED (they have this word in bold in the guidance) to the tank rather than drained to it, would I need to include these in the book? My rationing also is that I don't need to include every bowl discharge from the purifiers to the sludge tank, so why should I have to do it with oil drains? The paragraph I am referring to is this one:
Operator initiated manual collection where oil residue (sludge) is transferred (transfer with a pump) into the oil residue (sludge) tank(s).
The page I am referring to is this one http://www.imo.org/blast/blastDataHelpe ... me=736.pdf
The reason I ask is because I inherited this book from the previous engineer, and before the weekly declaration of tank quantities on the same day he would always put x amount collected from fuel oil drains to make up for the increase between last weeks numbers and this weeks, since the tank had increased without any transfers to it. Which also doesn't make a lot of sense because if you were to take that statement at face value it means you have managed to drain say 2 tonnes of oil in a single day rather than over the whole week.
So, any thoughts? Any input is as always appreciated.
