I'm pretty happy with most of the material now but.. some very simple questions that I am struggling to find answers to because I've never actually physically seen the items in question. (I'm transferring from Royal Navy - Submarine, so very different.) Never got time off work to do an oral prep either unfortunately.
1. With respect to the 2-Stroke Diesel, will I be expected to know about Dual Fuel Diesels and their cycles?
2. I'm confused about the Scavenge Belt - what actually is it? 
The Scavenge auxiliary blowers - are they constantly running? Are they simply motors turning fans in the scavenge inlet?
When the Scavenge fire procedure mentions firing a portable fire fighting appliance into the Scavenge Belt? (Or use the fixed one)
3. Why do you have to increase lubricating oil into the cylinder in the event of a Scavenge Fire?
I'm guessing it's because you have to take it to it's slowest running speed and lub oil pump driven from crankshaft? I just don't get why that particular cylinder needs it because you're only isolating the fuel? (Sorry if it's a basic question but would appreciate clarification)
4. Do the large two stroke engines have a turbo fitted to each cyclinder exhaust? Or a common exhaust with one turbo?
5. What temperature do the double bottomed storage tanks keep HFO? Are these still steam coils?
6. Does the boiler fuel come from the same settling tank as the Diesel or are they seperate tanks?
7. How often is the fuel transferred from the storage tanks to settling tanks? I understand the service tanks/day tanks hold 24 hours worth of fuel? are there float switches that automatically transfer the fuel between tanks or is it done daily?

I think these questions are so simple that's why I can't find the answers!I hope someone can help me out and I appreciate any help.

Please help

I didn't find the right solution from the internet.
