7th day of Refloating Vessel Operation

(continuation)

On the seventh day we were at the actual location where the ship sank. We have to find the sunken ship using an old sonar and we spent less than 2 hours to find it. We found the sunken ship and anchor down to fix our position. According to the sonars information, it is 210 feet below because of the tide but it should be 190 feet according the captain and the crews of the ship. I know it's part of the of our scuba diving service to risk our lives but that doesn't mean we can just ignore the dangers. We told them that should the reason why the other team have casualties. The ship is too deep, meaning whenever they dive that deep they have to decompress because their live is at stake. The problem is they do not have a supervisor that can take note of the depth for decompressions. As i wrote before, these divers did not have any formal training which a commercial diver should have. They only acquired experience in scuba diving from extracting mussels from rock beneath the ocean or cyanide fishing and they dont even know what is decompression or wether they need it. So five of them died without knowing what realy happened to their comrades. They didn't have diving log book or anything that could track down their dives according to the crews. All of the former crews of the operation suffered bends.

We have our decompression book manual from the US Navy for decompression guide. We use slate and a pencil attached to a rope to tally our depth and decompression time and tie it to our body. Our scuba tank is equiped with depth gauge so we removed the depth gauge and tie it as well to our body. Instead of using scuba tank we use their air compressor. Their air compressor is up and running but they only use ordinary hose and nothing else, they just tie the hose to their hips and bite the end of the hose to breath. To improvise the compressor we attached the second stage regulator at the end of the hose and used adjustable clamp to secure it. At first there is a small bubbles coming out so we fixed it and test it again. Now we are good to go.
