The U.S. Army Corps of Engineers (USACE) continues working to restore the deficient reaches of the Mississippi River Ship Channel (MRSC) 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 hopper dredge STUYVESANT will start dredging in SWP next week.
The hopper dredge BAYPORT (Manson Construction) is now expected to arrive in SWP by mid-June with approximately 30 days of dredging left to complete a Hopper Dredge Rental Contract.

GOVERNMENT HOPPER DREDGE(S) IN SOUTHWEST PASS (SWP):
WHEELER: The USACE’s hopper dredge WHEELER continues dredging on assignment at the Jetty End of SWP (Mile 18.2 BHP to Mile 19.5 BHP). The WHEELER’s usage is approved under Red Flag Emergency Callout #1-2020 for 60 days of utilization in response to not receiving any bids to Southwest Pass Hopper Dredge Rental Contract #2-2020 (February 6, 2020).

CUTTERHEAD DREDGE(S) IN SOUTHWEST PASS (SWP):
CAPTAIN FRANK: Weeks Marine’s cutterhead dredge CAPTAIN FRANK is dredging at Mile 6.34 BHP and working on assignment from Mile 4.9 BHP to Mile 6.5 BHP on the western side of the channel. The cutterhead is expected to move to the next assignment from Mile 15.8 BHP to Mile 18.0 BHP tomorrow (Wednesday, May 13, 2020). The cutterhead commenced dredging in Southwest Pass on January 24, 2020 under Southwest Pass Cutterhead Dredge Rental Contract #3-2019.
CUTTERHEAD DREDGE(S) IN THE HOPPER DREDGE DISPOSAL AREA (HDDA):
CAPTAIN FRANK: The cutterhead dredge CAPTAIN FRANK (Weeks Marine) will resume dredging in the HDDA upon completion of their assignment in Southwest Pass. The project is to beneficially place material removed from the HDDA in the Pass A’ Loutre Wildlife Management Area (PALWMA). The cutterhead dredges have previously removed and beneficially utilized approximately 13.10 million cubic yards (mcy) of material from the HDDA and restored roughly 1,048 acres. Supplemental funding allowed the MVN to increase the amount of material to be removed from the HDDA to a total of 15.075 mcy. When this project is completed later this year, approximately 1,200 acres will have been restored in the PALWMA.
