DEATH By Pressurized Diving Chamber, IRAN

Six Indians - all dead, were part of a team installing an underwater oil pipeline and were inside a pressurized diving chamber when their Koosha-1 ship sank in the Persian Gulf, about 15 miles (25 kilometers) off Iran’s coast.
The diving chamber was on board the ship when it sank, and the divers were already inside to avoid having to pressurize and depressurize for their dives.

The Iran-flagged Koosha-1 left from offshore oil rigs near the underwater South Pars gas field, the largest in the world, shared by both Iran and Qatar.

Reports show that they died because they ran out of oxygen and due to carbon dioxide poisoning.

Six Indian divers were enclosed in a saturation chamber on the boat to depressurise after a diving expedition when the boat ran into bad weather. After the boat capsized, others onboard managed to jump into the sea, but the divers remained trapped in the chamber.

The saturation chamber was equipped to keep the divers alive for 18 to 20 hours (other sources say 72 hours).  The boat sank in just four minutes and went 70 meters down before it hit the seabed.
