With the buoyancy control measures in place and the 32-in. Once placed on rollers, the pipeline was ready for installation. pipeline in one continuous piece over two sand dunes and three valleys. pipeline installation.ĭuring the reaming phase, the Bolinter construction crew had strung, welded, coated and tested the 32-in. The hole was finally swabbed with a 42-in. This step was followed by a reamer pass that measured 36-in., followed by a 48-in. Once the down-hole assembly was removed, crews attached the reamer on the project’s pipe side of the crossing and pulled back towards the drill rig. steel pipeline installed by horizontal directional drilling in one single pull. Upon completion, the as-built pilot hole reached a depth of 84 ft and a world record length of 6,575 ft. The pipe string torque remained low enough during the drilling activity that the on-site steel casing was not needed. However, a couple of the days were described as long. The jetted nine-inch pilot hole was completed in only four single-shift days. The silt, sand and clay soil conditions encountered along the drill path were ideal for a crossing planned for over 6,500 ft. Once at the project site, crews were able to complete rigging-up in two days and start work on the pilot hole. ![]() The rig was a Laney built 800,000-lb rack and pinion horizontal directional drilling rig. LDD Rig 14 was mobilized to the first crossing at the Rio Grande site. Trucking the drilling equipment overland took an additional 15 days. Three weeks later the cargo was cleared through local customs in the port of Arica, Chili. Logistics of shipping two complete drilling rigs to Bolivia with all possible spare parts.Īfter creating the larger pieces of equipment in Houston and loading the smaller items into nine containers for ocean shipment to Bolivia, the 42 loads were prepared for transporting and placed on a ship.The Rio Grande and the Parapati Rivers posed several challenges for the Laney-Bolinter team. ![]() The coating was fusion bonded expoy (FBE). Design specifications called for the lines to be built with X-70 pipe, with a wall thickness (wt) of 0.688. The directionally drilled portion of this section of the South American natural gas pipeline project consisted of the design, engineering and construction of two 32-in. provided the pipe fabrication and local support capabilities. Humble, Texas-based Laney Directional Drilling, Inc., provided the drilling experience and Bolinter Construcciones Petroleras S.A. Transierra, a partnership composed of Petrobras, TFE and Andina, selected the Laney-Bolinter joint venture after a thorough search for a horizontal directional drilling contractor with the experience and capability of meeting the challenges of the long installations. The Laney-Bolinter crews established the record on the Rio Grande project. Combined, the crossings of the Rio Grande and Parapeti River’s measured 11,989 ft with the Rio Grande crossing extending 6,575 ft and the Parapeti extending 5,414 ft. section of the owner company’s GASYRD natural gas pipeline project. The two river crossings were part of a 138-mi, 32-in. Laney-Bolinter, a joint venture company, set a world’s record for directionally drilling a long-distance river crossing with large-diameter pipe when it successfully installed two river crossings in southern Bolivia for Transierra Pipeline S.A.
