All dredged materials will be placed into designated Beneficial Use of Dredged Material (BUDM) areas for marshlands restoration, providing ecological benefit and storm surge protection for the surrounding area. Dredging operations are expected to commence early 2026.

The Galveston Entrance Channel and Houston Ship Channel from Bolivar to Redfish maintenance project, which was awarded in the second quarter of 2025, involves dredging to maintain operating depths for the channel area.

Work is expected to start in the third quarter of 2025 with estimated completion in the fourth quarter of 2025.

The Mississippi River Hopper Dredge Contract No. 3, which was won and awarded in the second quarter of 2025, involves rental of a trailing suction hopper dredge for maintenance dredging on the Mississippi River from Baton Rouge to Gulf of Mexico Southwest Pass. The client on this project is the U.S. Army Corps of Engineers, New Orleans District and is federally funded. Work started in May of 2025.

Lasse Petterson, President and Chief Executive Officer commented, “These projects enable Great Lakes to play a vital role in enhancing the resilience and sustainability of the nation’s environment, coastlines, and critical infrastructure. We have also strengthened our presence in the LNG and broader energy sector with our award of Woodside Louisiana LNG. These initiatives are essential to advancing U.S. energy infrastructure, supporting increased export capacity, and aligning with national energy security priorities. These four awards contribute to the growth of our 2025 dredging backlog, further solidifying our revenue visibility for the remainder of the year and into 2026.”
