The U.S. Army Corps of Engineers (USACE) continues working to restore the deficient reaches of the Mississippi River Ship Channel with two industry hopper dredges, a government hopper dredge and one industry cutterhead dredge. The industry hopper dredges GLENN EDWARDS and NEWPORT, the government hopper dredge WHEELER and the cutterhead dredge CAPTAIN FRANK are all working in the area of Southwest Pass.
The MVN received an awardable bid from the Dutra Group to the bid opening for Southwest Pass Hopper Dredge Rental Contract No. #5-2020 today. Dutra’s hopper dredge STUYVESANT will be under contract to arrive in Southwest Pass by May 20, 2020. The MVN continues to review the four bids received on April 21, 2020 to the advertisement of Southwest Pass Hopper Dredge Rental Contract No. #3-2020. This advertisement was for a large hopper dredge to arrive in January 2021. The bids received remain under review, based on the reporting time this process may take longer than usual to resolve.
