FUJI Vegetable Oil Project
Microtunneling
Huxted Trenchless installed 660 LF of 72-inch OD Permalok steel casing by microtunneling between two 36-foot-deep shafts. The completed tunnel serves as a protective casing for multiple carrier pipes supplying the FUJI Vegetable Oil facility.
The alignment passed beneath 14 active railroad tracks owned by Union Pacific (UPRR) and BNSF, as well as a Louisiana DOTD right-of-way, in Avondale, Louisiana, adjacent to the Mississippi River. The crew advanced the bore through challenging ground: a high groundwater table and weak soil strata with high organic content and buried wood debris.
