Freeport LNG Terminal
The Freeport Liquid Natural Gas (LNG) terminal is located on the eastern end of Quintana Island, adjacent to the intersection of the Freeport Ship Channel and the Gulf Intracoastal Waterway. To accommodate the newest class of LNG carriers, the entrance and jetty channels need to be widened from 400 to 600 feet, and the depth increased from 45 to 47 feet. We performed engineering and regulatory permitting services to widen the ship channels.
Our work included bathymetric and seismic surveying, as well as a geotechnical investigation that included analysis of jetty stability for the widened channel. We also analyzed dredged material fate to determine possible offshore placement of 2.9 million cubic yards of material; 300,000 cubic yards of dredged material will be used as beach nourishment approximately two miles south of the channel. Multiple measures will be taken to protect sea turtles during dredging and beach nourishment activities.
Navigation safety and potential impacts on other traffic were major considerations. We conducted extensive analysis and vessel maneuvering simulation studies to determine the optimal arrangement for the berthing area. Our team also assisted in site selection, project planning, environmental impact evaluations, marine terminal design and regulatory phases.
