The Salt Ditch & Intracoastal Waterway (connecting Sempra LNG's new Cameron LNG receipt terminal to existing interstate pipelines to the north of the LNG facility) crossing required the installation of 16 horizontal directional drills ranging in length from 1,300 feet to 5,000 feet. In May 2008 Laney mobilized equipment and supplies to the drill site on the east side of the waterway. This included one of the largest HDD rigs in the world, capable of 1.7 million pounds of pullback. Drilling the 9 5/8-inch pilot bore took 14 days. The initial 6,669 foot drilling operation was precisely on target. Our crew made several reaming passes, swabbed with barrel reamer to ensure the bore path was clean and ready to accept the pipe section. Pullback began on July 10 and was completed just four days later and ahead of schedule. The entire project took just 56 days to complete and set a new distance record for a large diameter HDD crossing, surpassing the old record by approximately 570 feet.
