Laney completed a record 10,971 ft horizontally directional drilled pipeline crossing that parallels the FM 1960 bridge crossing Lake Houston in northeast Harris County, Texas. The HDD crossing originally started as a design-build project and included a six-inch-diameter steel gas pipeline with a 0.432 wall thickness, fusion-bonded epoxy coating and an abrasion-resistant overlay. Besides the record-setting length, the Lake Houston HDD crossing had logistical challenges at both the entry and exit locations. On the entry side, Laney had to set up its rig between two existing, in-service pipelines. The dead man and LDD-750 rig on the exit side also had to be modified to fit in the space available, and Laney even had to move a section of old pipeline at the site to fit the drilling equipment. Laney's team effort helped make this a successful project.
