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....
