Thread: The end of cruise ships, as we know them?

That's impossible Trout . The passengers caused the spread themselves . I'm genuinely sorry for the loss of life , but it could have been prevented by good personal cleanliness and hygiene.

And now it seems over the last few days, also by better Air Conditioning design, use & maintenance.


I did raise this way back but the response was that it should be impossible.

Lets face it, you cannot recirculate Virus Aerosol laden air & hope to get away with it. So much should & must be learnt from this C-19 business.

It was interesting that when we left Tassie on the Spirit of Tasmania they assured us that the aircon for each section of the vessel drew its air from outside and not from other parts of the vessel. AFAIK there have been no cases of the virus on the Spirit. So apparently it can be done.

A full fresh air system,i doubt it,particularly when in a salt laden humid environment.

At the least, the system would be drawing return air from other cabins,with a small % of outside air.

Yeah, that is the normal setup for a normal land based system & I can think of no reason to alter that design. Mick, it is a Pressurised setup because of the intake of outside air. Maybe Old Farang might have a view on it?

No just the tourist run in the big speed boat there .

I have not worked on cruise ships, only big offshore drillings rigs with around 120 crew. All of them that I have worked on recirculate. A bit out of it now, but I believe the design criteria calls for something like the following:

The current standard for inside and outside air in cruise ships requires they have 10 liters per second per passenger of outside air in a cabin, he said. The air inside a cabin that is returned, or carried, to other areas could be up to 90% of the total air in other spaces. In other words, that 90% could contain coronavirus if it came from an area where someone had the virus.

That just gives the flow rate, does not mention the makeup ratio.

Does that really mean just shut the stateroom door and open the the window (portholes are only good for the LHS)?
