Lower Mississippi River to be dredged to 50 feet. (not a river pilot thread)

I know pilot salaries are the hot topic of the day, but that represents a very small portion of the costs to ship goods. as ships continue to be built bigger, deepwater access is the real issue that determines the lower Mississippi's competitiveness, as a port, with other gulf coast and even east coast ports.
ever since the new Panama Canal locks were opened, there has been a race to 50 feet among gulf coast and east coast ports including the lower mississippi (Port Nola, Port of Baton Rouge, Port of South Louisiana) Houston, Mobile, etc.
For those that do not know, ships are built to maximum size to fit through the Panama and Suez canals. With the new panama canal locks opened, that has resulted in a new class of ship, Neopanamax, and now it is up to the ports to accomodate these larger vessels.
these are different sizes for tankers, but bulk carriers, general cargo, and containerships are all built in similar size categories.

Today, Gov. John Bel Edwards and other top Louisiana officials signed a formal agreement with the U.S. Army Corps of Engineers to begin construction on the deepening of the Lower Mississippi River to 50 feet from 45 feet. This project will provide deep draft access to the ports at Baton Rouge, New Orleans, South Louisiana, St. Bernard and Plaquemines.

“When completed, this project will allow larger vessels that can currently use the widened Panama Canal to reach Louisiana ports as far north as Baton Rouge. It will also allow for some vessels to carry heavier loads

Good. We have no topography, we need to dredge every river in the state.

I just hope one of those big bastards doesn’t hit the levee during flood stage.

Good news. Amazing what a difference a couple feet makes.

I’m gonna need several, multi-year studies on environmental impacts before they move forward with this.

I thought this wasn’t a river pilot thread?

Seems like a small change. I feel like the river bottom could frequently vary that much due to silt. But I'm not a river scientist.

It's not. But I'm sure it'll turn into one anyway. Fact of the matter is, it can cost $800,000+ in tariff fees just to get a neopanamax thru the canal so pilot fees are not the biggest concern for these shipping companies

The USACE already has constant dredging operations underway to maintain 45 feet. This will just result in expanded dredging operations

Thanks.
Why is it a new project? Couldn't they just start going deeper during their routine operations?

What kind of mileage of river are we talking? That sounds like a huge undertaking.
Posted on 8/1/20 at 12:21 pm to Captain Crackysack
Pretty interesting!

More being sarcastic, but yeah.

The USACE currently maintains a "navigable channel" of 45ft depth and 750ft width. There are sections that are less than 45 ft deep but as long as there is a 750ft wide section that is 45 then it is not dredged.
There are also large sections of the river that are already much deeper than 45 feet. This project won't result in the entire 250ish miles from SW Pass to BR being dredged, just the sections necessary to provide a minimum depth of 50 ft along the entire route

Where are they dumping the sediment? Hopefully in the swamps.

And more opportunities to use that silt to build land and restore marsh. If they will do that, as opposed to dumping it in the damn ocean.

Panama Canal Max: Panamax (old)
New Panama Canal Max: Panamax (new)
Suez Canal Max: Suezmax
Straight of Malacca Max: Very Large Crude Carrier (VLCC)
This amuses me

The sediment from the first 30 mile section of river will be used for wetlands restoration. The rest of it will probably just be released into the water column and let the river take it away
Posted on 8/1/20 at 12:33 pm to Captain Crackysack
They should load the silt from this project onto barges and start another project for coastal restoration
