Water Injection Dredging (WID)

Category:

Dredge Plant

Description:

Water injection dredging (WID) has been used in Europe and Asia since the 1980's, and the

United States since 1992. WID dredge is owned and operated in the U.S. by Gulf Coast Trailing,

a subsidiary of T.L. James Marine Group, and partner with the Dutch firm HAM. HAM has the

worldwide patent on WID technology. WID has been primarily used along the Mississippi River

for removal of shoaled material around docks where the dredged material can be fluidized and

redirected into the river flow for deposition in deeper sections of the adjacent channel. Other

advantages of WID include:

1) An area that contains debris can be dredged successfully without effecting production.

2) Dredging can be conducted under docks and congested locations .
