You can start reading the specifications and datasheet that AFB and compare it against technical data submitted by vendors. You will stumble upon unfamiliar things and that's when your Internet will become handy. Google up for things in the specifications and datasheet that you don't know. This will leads to one thing to another. While you are at it, get familiar with PTS and DEP (which indirectly related to IEC, BS and etc.). If you can't find the information that you wish to get, walk-up to your lead and ask.

Also, you can always ask your vendor for better explanation.

If you have a chance to go to yard whether during construction or commissioning, by all means make yourself available. You'll get better picture.

I think that is the only way for you to pick-up the technical knowledge.
