Diving Ops



Today we had a tour of the dive facilities on board the Alucia. The Alucia is very well equipped for scuba diving.

She has a decompression chamber, which is used in case of a diver gets the bends. This is a condition in which dissolved gas comes out as bubbles inside the body and the diver must be recompressed and then slowly decompressed as treatment. The chamber looks like a giant tick-tack with port holes in it.


Surprisingly it has a capacity for 3 people: the patient, the nurse, and a third diver.  Before entering, you must be completely washed, re-clothed in natural non-flammable fiber clothing and stripped of all jewelry. The reason for this is that you will be breathing oxygen and O2 feeds fire.  The whole procedure takes several hours, but it has a little exchange window by which they can pass you a blanket or a snack without de-pressurizing the entire system.  


None of this sounds like fun, so I will be diving very conservatively, and drinking lots of water and sleeping well in order to dive safely.  

To our good fortune, the Alucia also has mixed-gas dive support, which will allows us to dive with air that has 32% oxygen instead of the normal 21% oxygen.  Using this oxygen enriched air with a conservative dive plan decreases the possibility of getting the bends.  

The mixed-air support, plus the chamber make the Alucia an excellent dive platform for a month-long expedition to remote islands.
