Javeler strives to
offer a reasonably priced, efficient and environmentally responsible
service in dredging, mitigation and restoration. We are committed
to superior environmental practices and the utilization of best
available technologies to implement them.
Javeler has a long history in
moving the earth. From the dragline as its main tool to the
submersible dredge pump. Javeler understands the environmental
consequences of dredging and makes it a priority to
offset, minimize, eliminate and compensate environmental
degradation. The dredge pumps utilized by Javeler contribute
very little to suspended solids and turbidity when
compared to other forms of dredging. Our submersible dredge
pump uses less energy, is less invasive, easier to control; and
the option for electric pumps eliminates opportunities for
hydraulic oil spills.

Dredging Contaminated Sediment
"Along the bank of the Hylebos Waterway in Tacoma,
Washington 32,000 cubic yards of contaminated sediment is being removed and
treated, including some of the most dangerous chemicals in the Commencement
Bay.
Javeler was selected as the preferred contractor due to our 20+ years of
experience dredging with the Toyo submersible dredge pumps. The Toyo
submersible dredge pump was specified as the preferred method of dredging
due to the limited turbidity created when dredging as well as the high
solids content when submerged in material. The treatment costs are
considerable, so the focus is dredging at the highest solids content
possible. Material is being pumped 2,000 feet to a treatment/dewatering
process. The sediment is then trucked to a disposal site.
Javeler is using a Manson derrick where a Toyo 8 inch submersible agitator
dredge pump is hung from a crane. A Trimble GPS system is
mounted on the end of the crane to control the dredge pump location.
A Trimble depth sensor provides accurate depth measurement. A magnetic
flow meter/density meter provides percent solids and production numbers.
An electronic tide gauge corrects for tides. All info is sent to the
laptop computer in the operators cab. A Trimble dredge software
package takes all the data and displays live readouts/contours/3D
visualization of what we are doing under water. Progress
surveys are completed on a regular basis with multibeam dual frequency GPS
equipment to confirm dredging results. "

Wetland Restoration
This project was for marsh restoration near the mouth of the Neches
River. A spoil disposal area was created from the dredging of a canal,
a cooling water supply source for the power plant, was excavated down to
natural marsh levels to create “coastal prairie” . The excavated spoils
were hauled to a centrally located pit, mixed with water from the canal
to form slurry and pumped into the dead marsh area to form islands and
higher elevations to promote growth of vegetation.
The goals were accomplished with great success.
Burying
a 36' live gas pipeline
A large oil company came to Javeler for
assistance in burying a 36 inch live gas pipeline in shallow water in
the Gulf of Mexico. Javeler designed and fabricated a twin dredge pump
system to straddle and bury 7,000 feet of pipe - still under pressure.
The job was successfully completed in 2.5 weeks. A ROV sweep revealed
no damage to the pipeline coating.
Filling Geotubes
Javeler was involved with
a beach stabilization project for NASA. 4,600 feet of 34’ circumference
tubes filled up to 6’ in height with a medium grained sand. Excavators
fed the sand to Javeler's hydraulic drive 75 hp submersible agitator
pump which was placed in a 30' x 20' x 5' deep pit. The sand slurry was
pumped through 2,300 feet of 8 inch HDPE pipe to fill the geotubes.
