Black Smoke not White

[deborahjo]

Has anyone else seen the black smoke coming out of the Liberty this morning? The only other time I have seen this was when were on the Splendor and it as pouring out oil which explained the black smoke.

 

Usually the smoke is white from the smoke stakes. Just wondering.

We just got off her and didn't hear about anything going on. Not sure what's up.

I was just wondering. I know she cannot break because I have 120 days.

All diesel ships produce black smoke. it may have been carbon buildup in the exhaust unless it was while the ship is at sea and pushes the speed. Several different engine, motors, pumps and generator systems are vented through the stacks.

Despite what some may say, black smoke from a diesel engine is not a normal emission and may be caused by a variety of things. They are not intentionally burning off anything when this occurs, and it is severely frowned upon when it occurs in port.

 

Here's a couple of articles to read:

Not saying anything is wrong with the ship, but...:confused:

Hi :)

 

I see this so often on many cruise lines. Your 2nd link is a very good

read and extremely informative.

As soon as you see white smoke it will mean a new Pope has been chosen.:D

Maybe they switched over to coal power.

On our April 12th-19th cruise on her, the we're a few alarming announcements and they cleared people out of a few floors on the aft part of the ship. They later announced that some generator below deck was smoking. And it smelled for a little on decks. Captain was on the pa about 4 times. Heard alarms in the background. Then within 30 mins, all was clear

Generators can certainly be responsible for such emissions, as evidenced with the HAL ship in Alaska (my first link).

I thought the switch to white smoke signified that a new Captain had taken the helm? ;)

Was it sustained, or just momentary, or a minute or two?

 

Several causes of black smoke.

 

1. Starting up another generator. All diesels will smoke to some extent when started. As the ship comes up to sea speed, they will start more engines as needed. This will generally last only 10-20 seconds or so.

 

2. Boiler soot blowing. Normally done at night, to reduce the comments from passengers about the black smoke and soot particles. This may last a minute, and be repeated for 2-3 times in a 15 minute span. This is a normal, daily occurrence, when not in port. Could also be from starting a boiler, but this gives a short puff like the engine start.

 

3. A stuck fuel pump on an engine. This causes one cylinder of the engine to put too much fuel into the engine, and the incomplete combustion will cause a large billow of black smoke. This can last until the engineers see the smoke on the "stack" cameras (most ships these days have cameras looking at the exhaust for just this reason), so maybe 3-5 minutes. This is a relatively simple repair, and happens maybe once or twice a year on any given ship, the repair can be done in about 3-5 hours, and shouldn't affect the cruise or any future cruises in any way.

OMG -I was thinking the same thing - especially because of the title of the post. Too funny!

Nothing is allowed to happen to the Liberty since we'll be on her next year. :):rolleyes:

 

Better now than then!
