Atchafalaya River Bar Channel Agitation Dredge

Collaborating with USACE, Brice designed, built, and now operates an innovative, first-of-its-kind agitation dredge to pump colloidal shoaling in a cost-efficient way. The Arulaq (Yup’ik word for agitate or stir) operates 24/7, exceeds 5 million cubic yards of dredge material per month, and operates at one-third of standard dredging cost. The jet nozzles on the drag arms agitate the river bottom to suspend dredge material for discharge while deflecting turtles away from the vessel. This dredging activity reopened the channel to deep-draft navigation.

Due to our success on this contract, we were awarded another 4-year contract to continue dredging operations.
