Great Lakes awarded dredge and disposal contract for Port Arthur LNG


US dredging services provider Great Lakes Dredge & Dock Corporation has been awarded the marine dredging and disposal contract for Sempra’s Port Arthur LNG Phase 1 project.

Located in southeast Texas, with direct access to the Gulf of Mexico, the Phase 1 proposed project will include two natural gas liquefaction trains with a capacity of up to approximately 13 million tonnes per annum and new natural gas pipelines to deliver natural gas to the terminal.

Expected commercial operation dates for Port Arthur LNG Phase 1 Train 1 and Train 2 are 2027 and 2028, respectively. Sempra Infrastructure is also evaluating potential carbon capture and/or hydrogen facilities at the site.

For Great Lakes, the scope of the work on the project is to dredge the berthing pocket on the Port Arthur ship canal. The berthing pocket and turning basin will connect to the Port Arthur ship canal and will allow LNG vessels to berth, load, and depart safely.
