Crew Named For 'Project Poseidon'

Saturation diving is a standard method of working in the commercial diving world. Divers live in a pressurised environment or 'SAT system' for many weeks. Once their work duty has finished the divers are decompressed to surface pressure over a period of hours or days.

Tech and Training

Today SAT time is limited in many countries. In Norway the maximum bottom time is 14 days and the diver needs to be offshore no more than 21 days. Meanwhile in the British North Sea the time in SAT (including decompression) is limited to 28 days. However there is no limit on statutory offshore time, hence the diver can remain offshore for a number of days before being transported back to the mainland.

Technically Speaking

Simon Pridmore's aim in writing this book was to examine and record where technical diving came from, how it developed, how it expanded across the world, who the important movers were and how the efforts of a few determined people changed our little field of human endeavour forever.
