1st Visual Inspection dive in the GOM

Here's my friend first inspection dive in the Gulf of Mexico. He's mainly a construction diver/tender so the dive supervisor explained many parts of the platform inspection to him. Above is the plateform that was inspected, everything changes though once you go below the water...The videos are a good reference for visual inspection dives in the GOM. It's a night dive so the water is black, and yes he's from Australia.

Here he's traveling to the platform via the downline, it's the last dive of the inspection so he's also cutting the downline away from the platform.

The diver is walking to a node in the members, supervisor discribes to the diver what he is seeing.

This is the visual inspection of a zinc anode on the platform, the supervisor explains it all.

After a 40 foot inspection the diver leaves bottom, to the boat deck.....

Hand Jetting








The top picture is of the Jet nozzle. This is held by the diver to dig into the ocean floor to either help to expose pipe or to make the hole the pipe will be buried in. The pipes can be buried anywhere from 3 foot to 20 foot below the oceans floor. Burying pipes helps to protect them from the seas during hurricanes or other rough weather. The next picture is of the trash pump that helps bring suction of the sea to the actual jet pump, when working on a platform or semi submersible vessel this is needed to help provide extra suction of sea water from higher elevations. Next is the actual Jet Pump, it runs off a diesel engine that powers the pump. You can see the suction hose is hooked up and tied off to the actual jet pump, it's the pink hose with yellow rope tying it off for whip back safety. It's referred to as "the donkey dick" in the field and is heavier than hell once flooded with water. The jet pump can produce 400 psi to the jet nozzle, which is what fire fighting hoses are pressured to annually. The video is what it looks like on the surface while jetting is happening on the oceans surface. If you want to see what it looks like in the water, turn out the lights in your room put on a blind fold and think about handling a rubber fire hose pushing out 400psi....
