 Deep Water Dredging

Dredging To New Depths

One of our clients was working on a tension leg platform (TLP) drilling rig 150 miles offshore in the Gulf of Mexico and came to Javeler looking for a dredging system to remove mud inside of 7' diameter anchor piles in 4700 feet of water.

We modified a standard Toyo hydraulic submersible agitator pump with the addition of accumulators filled with oil for pressure equalization. Javeler designed and fabricated an independent support structure that was positioned on top of the pile. A hydraulic winch on the structure lowered the pump down 20' inside the pile and excavated the sediment. The slurry was discharged just outside the pile. A hydraulic jet pump, also on the structure, provided flow to the jet ring on the Toyo dredge pump to assist in cleaning the inside of the pile. All equipment was run hydraulically from a ROV.

Uncovering buried jack up legs

A large salvage company hired Javeler to uncover stuck jack up legs that were covered and damaged from a hurricane.  Javeler excavated 50 feet of mud that was burying the jack up legs. The maximum depth achieved for this project was 350 feet deep.  The project was a success.
