So, what’s going on here? Well, this is our BSAC expedition grant mentor, the First Class JD dealing with Naomi and Mike.
They were silly enough to ask what a triple expansion engine was. They probably were expecting a one-line answer, rather than a full schematic diagram, scribbled on the back of a dive log, together with an explanation of the key bits to look out for on the dive. If anyone from BSAC HQ is here, you’re looking at a sure fire winner on next year’s National Instructor exam…
This morning, we tested out our new found knowledge on the wreck of the Tonis Chandris in very good visibility. A lovely dive, with all the bits of that triple expansion engine nicely on display. We had to beg JD not to upload his diagram.
We want JDs diagram…just to be sure

Um, I already knew how a triple expansion engine works… does that make me a first-class diver?
