Saturation Diving: Life at 600 feet down. Good pay but the toilets can kill you.

Using the toilet can kill you… at least if you're living for weeks inside a saturation chamber. In this Pod Diver TV episode, Joe Cocozza sits down in Lisbon, Portugal with former Portuguese Marine and commercial saturation diver João Rainho to unpack what life is really like as a sat diver. João walks us through his path from spearfishing Marine to IMCA-certified commercial diver, North Sea contractor and finally saturation diver working worldwide. He explains how sat systems work, why divers spend 28+ days pressurized instead of bounce diving, and how an entire vessel—from cooks to life-support techs—exists to keep a handful of divers alive around the clock. João breaks down the pay and danger myths around saturation diving: which sectors actually pay well (North Sea, Norwegian, Dutch, UK), where safety slides (Gulf of Mexico, Persian Gulf, parts of Africa), and why some new divers quit after a single sat. He talks candidly about long hitches away from family, the psychological strain of living in a steel tube, and the strange realities of everyday life under pressure—including how flushing the toilet the wrong way can be fatal. We also hear about his dream expedition: crossing the Atlantic from Lisbon to New York underwater in saturation mode. If you're curious about commercial diving, offshore oil and windfarm work, deep decompression, or what sat life is really like beyond the movies, this interview is for you. To watch video goto:
