Drawings?

[Lewis]

So am off to sea for my second sea phase and I was looking over my companies feedback on my TRB/workbook. The feed back was positive the only thing it pulled me up on was having to many photocopies and photos and not enough drawings. What exactly should I be drawing?

Pipelines, diagrams, situational stuff (insert proper deckie phrase here)

(small hint: You should have a complete knowledge and some rather gucci drawings of all the pipelines that you deal with on your ship and you should get that from following them, not just pulling pipelines manual out. That includes ballast, fire, anti-heeling, cargo, steam, deck air, etc...)

Isn't that more an engineer thing?

Nope, you should have a complete knowledge of whatever system or valves that you could or should be able to operate.

Indeed! I have fond memories of tracing and drawing all the cargo and fire lines on a VLCC!

A small tip- if you are on a small vessel at the moment do the tracing and drawings of the lines on that ship and don't put it off!

Try a chemical carrier. We have 54 cargo tanks aboard, at least another 10 ballasting tanks, fire pumps, emergency fire pumps, valves, isolators. I assume a simplified drawing would be acceptable? Otherwise I could spend the entire trip trying to map out my vessels pipelines (and every cargo tank is much like the other with regards to the piping/manifold system).

Do each system separately, the most important one is the fire system, for cargo a simplified version would be fine I think, no need to repeat all 54 tanks, as long as you can demonstrate that you understand the setup and what valves each tank has for two or three.

In theory, as an OOW you should know where each valve is, what they operate, where the pipes go, etc so get out there and get drawing.

It only took me two days to map out a Suezmax size crude carriers Engine room and deck pipework....

Now your question is, why on earth would I do that, whats the point? If I never sail on this ship again, why should I need a drawing of the pipelines?

The answer to that is about understanding and that fundementally the systems on most ships are fairly similar. You need to understand how the fireline is sectioned, why it's designed in a particular way and how it interacts with the multiple pumps.
You need to learn to the ballast systems to understand why and how it is setup in a particular way.

In the early days, the ship seems incredibly complex, with pipelines, frames and wiring everywhere. Eventually it all becomes a lot simpler, and when you step on a new ship, you can easily trace the lines (normally).

Familiarity with a ship is important, and by drawing various diagrams, you have to genuinely test that knowledge and prove to everyone else that you've taken the time to at least think about what how the ship is designed. The assessor can discuss the diagrams with you to test your understanding.

Thanks for the advice. I've never been that artistic how do I represent 3D pipe work on a piece of paper. A series of plan drawings of each deck? Or a more abstract like London tube map style? does anyone have an old one of theirs they can upload so I can get an idea?

Just a line diagram of how it all comes together is enough. Go and speak to the Engineers on board and ask them to show how to do it. However, don't let them give you the pipelines plan as that's just cheating and you won't learn!

[Lewis]

still waiting on a ship that's why I thought I'd ask you fine people :P

London tube version is acceptable, BUT maybe a dashed line around certain sections to denote where they live....so purifiers and heaters surrounded but a dashed line stating Purifier Room and pumps maybe Bottom Plates etc etc, Then main thing is what is fitted to the system what each bit is for and safety items fitted etc
