[QUOTE=PaddyWest2012;98742]You should read the comments in the online news articles about this thing. I could only stomach a few of them before I had to close the page. The biggest common theme in them are all the laypeople yammering on about how flabbergasted they are that in 2013 a ship in the gulf of mexico cannot transfer 4000 people to another ship underway and then be towed back to port empty. I really want to slap these people and then attempt to calmly explain what death-party an underway transfer of 4000 individuals would be.[/QUOTE]
Yes, the harebrained ideas they have are entertaining. One comment I read the guy was adamant about bringing in crew change helos to carry people out- now just where did he think they would land that Sikorsky S-70?? On the miniature golf course?
[QUOTE=PaddyWest2012;98725]I was trying to get at a common thread like this about these incidents in an earlier post. Is Carnival installing a problematic power system in all of their ships over and over again? Was it the same system in both ships? Or is this a common operational error on Carnival ships regardless of their power systems? Obviously any conversation is only speculation until we know more but there is certainly the potential for interesting connections to be drawn.[/QUOTE]
How in the name of God does such a ship only have one HV switchboard or if it has two or more, why they aren’t isolated from each other? Anyone know anything about how the busses are arranged and what buss tie breakers would be installed?
Why are people pissing on the carpet? Why not piss overboard? Too much free time, or maybe I am having relapses to 6 year old bathroom talk but for Christs sakes, what a bunch of savages for not being able to maintain some level of order. That’s where some leadership could come in handy.

It would not surprise me one bit if there are punks roaming the vessel intent on trashing everything they can. Carnivore cruiseships attract those kind of bottom feeder humanoids. Of course, with a breakdown in leadership, things will spiral out of control in very little time indeed and something makes me believe that the master has not done one fucking thing to try to make things better on there for anybody but himself. I really am wondering how bad the stories are going to prove to be?
I just feel terrible for the old people and the kids to be suffering such an abominable insult to living.

If you ask me I’d say they’re damn lucky this happened in the second week of February instead of the first or second week of March. The spring-break crowd hasn’t arrived yet! Just imagine what a difference a couple of weeks would have made! There would have been drunken frat-boys roaming all over the place smearing every available surface, both inanimate and alive alike, with all manner of bodily fluids. I’m sure we would have seen a good many more brawls and perhaps even sexual assaults as well. CARNIVAL indeed…
[QUOTE=Kingrobby;98732]I don’t have the time to look it up as I’m heading out the door, but I swear they used the same Wartsila engines on both ships. Maybe someone can look it up and report back with definitive information.[/QUOTE]
As catherder posted, Carnival Triumph has six Wärtsilä-Sulzer ZA40S series engines, two 12- and four 16-cylinder units in V-configuration. However, since it’s a diesel-electric ship built according to the power plant principle, there are no separate main and auxiliary engines.
As for Carnival Splendor, she has six Wärtsilä 12V46C’s. I don’t think the ZA40 and Wärtsilä 46 have much in common, other than the fact that in this case both were probably manufactured locally in Wärtsilä’s Trieste plant.
[QUOTE=c.captain;99547]This still doesn’t explain how entire HV switchboards were rendered unusable? THIS IS ONE HUGE STINKY AND I DON’T MEAN THE EFFING RED BAGS EITHER![/QUOTE]
They made sure to say in that article that how an engine room fire for one generator shut down the rest of the ship is an “on going” investigation, but at least we know what caused the original fire. They also said answers could be up to 6 months away. Gotta love bureaucracy.
The fact that these vessels have single engine rooms is yet another reason I will not ever take a fucking cruise. No emergency generators located elsewhere? And a couple thousand passengers aboard! Am I the only one who thinks this is freaking ridiculous?
They have three spaces for generators. Two in lower hull engine rooms and one separate emergency generator space. All three separated. That’s what makes these incidents so strange.
[QUOTE=Traitor Yankee;99773]To borrow from c.captain “then how the bloody fucking shitcakes” do they end up with now power?[/QUOTE]
Well that is certainly the question of the hour. The whole thing seems to hinge on that one technical difficulty. I would say that that is the question that the feds are trying to investigate right now, but being feds who knows if they’ve even gone as far as to think of that question? Maybe you should call them. Actually, on second thought, we all should, let’s get a tele-thon going! I know from watching PBS that those things can solve ANY problem under the sun.

Yeah, but if they run all the cables into the same cableway…and that gets damaged…it won’t matter how many working generators you have if you can’t feed the main or e switchboards.
And there lies the problem with this design. Seems as though several of Carnival’s ship classes have this same design flaw. Most of their ships are if the same basic design with only different dimensions and engines powering the system.
Why wasn’t that section of fuel line shielded or below the deck plates. The cruise ship I was on had sheet metal covering the entire fuel line above the deck plates and the rest of the line ran below the deck. The flex connections to the engine were below the deck plate. Any leak should have just caused a mess in the bilge.
Fuel leak fires are an age old problem that should have been solved year ago with sheet metal, lagging, and sensors. However it seems like we never hear about a high pressure fuel leak fire being averted by these measures.

When they say return line it was probably not a fuel line returning to the day tank. Assuming this is not a common rail engine each cylinder will have a high pressure fuel pump that times the fuel injection event and boosts pressure high enough to fire the injector, maybe 5000+ psi for an engine this size. Each bank of cylinders will have a supply and return rail and each jerk pump is connected to each rail with a flexible hose. Now the problem I have seen is that when the spill port in the fuel pump opens a 5000 psi shock wave travels through the spill port and into the return line hose. Over time this will fatigue and fail the hose. Such failures are surprisingly common and are not usually spotted immediately. You can push a lot of fuel through a 3/4 inch hose at 65 psi. It would only take a few minutes to have a really big mess on your hands, throw in a hot turbo or an exhaust manifold and you’ve got yourself a very significant engine room fire. Even with a manned engine room the watch spends most of the time in the control room and cannot be in all engine rooms at once on a vessel with multiple control rooms. Such a leak could persist for an hour before anybody does a round and even notices.
Take a look at this video, it documents two cruise ship engine room fires and has CCTV images of one fire developing.

The technical bulletin mentioned early in the film was issued by Wartsila and emphasized using the correct fasteners at the proper torque with periodic checks every x number of hours, as well as an addition of shielding in way of the exhaust manifold etc
I will need to look and see if the Wartsila engines were the same model found on Triumph…
