re: Pumps in NOLA flood protection system corroded in 5 years, supposed to last 35 years

The project was built per army corps specifications. Apparently they were too stupid to consider the possibility of salt water coming in contact with the pumps. They probably copied the specification from a job they designed in kanas.

Also, a lot of people like to shite on ACOE but I got to give them props. They have successfully forced the river to go hard left past BR and NO for over a hundred years when it wants to go straight to the gulf, but all that success will be forgotten the day it fails.
The USACE used to be a well respected organization and viewed as premier problem solvers. Since Katrina, rightly or wrongly, especially in NO, they're viewed as incompetent bureaucrats.
When my grandmother worked for them in the olden days (50s/60s) the USACE was generally viewed as competent and dependable. That's all changed. Now it seems like a much more adversarial relationship between the Corps and the general public. I wouldn't want to work there now.

Well, it isn't on them. It is Corps equipment. Upkeep is on the Corps. The article has a good bit of info, if anyone wanted to read.
The Corps is never in charge of O&M for flood control projects. It’s SWB

Pretty simple. You attach some copper here and there just like in the hull of an offshore vessel. Current flows there and corrodes it first. Change them out every five years instead of the entire hull , or in this case the pump. Saltwater/brackish water construction 101.

Give them some credit.
At least the pumps were actually installed this time.
Years ago there were pumps bought and paid for and were supposed to be installed and ready to run.
There was heavy rain and flooding afterwards and come to find out the pumps were never installed and the pumps were found in the weeds somewhere still in the shipping crates.
A few heads rolled from what I remember.

Bright you by the same people that hid backup generators in deep holes to “hide” them from the water.

I disagree. I see this as a design, specification, and implementation issue. Granted, I am not privy to certain details, but an issue after 15% of the estimated lifetime points to an issue pre-handover.

It`s hard to believe that all the parts of the pumps were suppose to last 35 years, like it sounds in the article.
It would be typical to have to change out and repair bearings, some moving parts and bolting etc. that would be found damaged during the planned inspection intervals.
Future inspection intervals and planned maintenance on each pump should be determined by the extent of damage found on this first inspection, to insure the pumps will not fail during needed operation.
If the extent of damage finds the pumps to be too costly to maintain and not dependable they may need to limp along until new redesigned pumps can be installed.

It’s all good, 1/2 the turbines don’t work anyway.

NOLA got cheap Chinese Pumps. Obama officials embeded in the Corp of Engineers pocketed the difference.
Yawn.
Yawn.

What in the hell were the inspectors and maintenance guys doing to let the pumps get heavily corroded?
If anything besides the pump casing is corroded then they specified the wrong materials. We put pumps in more severe seawater service all the time and they don’t corrode.
Of course the crooks in the city probably bid this to companies who knew how to bribe them instead of to companies who knew how to build it.

quote:idk what incident you are talking about but when you close tainer gates velocity increases and usually cleans out the chanel. I've seen shoals wash out and logs get split when sector gates close.
If I remember correctly sediment made it difficult to close the gates and it threatened to blow the whole structure out.

Try reading the thread and think about what you just posted.

So when they start corroding because said client didn't listen to what you said, is it your fault?
I disagree. I see this as a design, specification, and implementation issue. Granted, I am not privy to certain details, but an issue after 15% of the estimated lifetime points to an issue pre-handover.
In most of the infrastructure USACE builds, the ownership, operation, and maintenance is turned over to local entities. USACE does do periodic inspections every 5 years of these structures to confirm everything is being done...well seems this periodic inspection showed the local entity wasn't properly maintaining.
The Corp also gets a lot of shite pre Katrina but most of that blame should be focused toward the individual levee districts what fought more than the NOLA Catholic schools. It's actually amazing the New Orleans District was able to coordinate an 18 billion dollar system, designed and build within 5-6 years. It's an amazing feat.
