Report On How Water Aboard Two US Aircraft Carriers Was Contaminated Is Released

A photo from social media of water from USS Nimitz (CVN-68) in September.  

USNI News: Procedural Problems, Maintenance Lapses Led to Water Contamination Aboard Carriers USS Nimitz, USS Abraham Lincoln 

Water contaminated with jet fuel accidentally pumped throughout aircraft carrier USS Nimitz‘s (CVN-68) potable water system and resulted in widespread contamination that made 11 sailors sick in September, according to an investigation the Navy released on Monday.

One week later, dirty bilge water contaminated the potable water supply aboard USS Abraham Lincoln (CVN-72) after entering the system through a hole in the piping, according to a separate investigation also released on Monday.

WNU Editor: Looking at the picture above. Yup. There is definitely a problem.

of course they will blame the crew and not the officers in charge. some things never change...

Yeah, looks fine, sir. just discard the petro-layer and filter particulate through a coffee filter

It was this way in the 1980's and 90's as well. At least some things never change.

I do not understand. Pipes, end caps and valve handles(wheels) are color coded and also stenciled.

The voids are something the crew could do, but there is mention of yard workers. There is the faint whiff of Admiral Kutzenov problems. The yard workers are or were not incompetent. they might be ornery, intractable, blue collar Democrats, but not incompetent. Money is not going into the right buckets.

@$$ Fockers are still sending money to the Taliban. For that Taliban money, you could paint every void on every carrier and still have money leftover for other paint jobs.

Reading the USNI article, one of the root causes was incomplete documentation going back to

the last Westpac. I hate a single root cause assumption.

For a ship there are

Refresher training for Damage Control
Light ex for boiler main propulsion ops
Carrier Qualifications
and many others.

So the paper work of what fluid went into what void did not get properly documented. I would be more than happy to keel haul somebody, but looking at the op temp and Operation and Maintenance, Navy (OMN), you have to ask yourself "Who could have kept up?".

I had no idea they used voids for more than one fluid. For ships trim/stability? Operational need for flight ops?

Dov Sar or Goldstein might know.

Never saw a piping schematic for this ship type, but obviously certain systems are connected for whatever reason.

You can't fire the Commander, Reactor Officer, without firing the previous CDR whose staff did not keep records up to date. I don't think they will receive a letter. Not sure that it would be fair.

I generically blame congress. They did look into steroids in baseball. That was important.
