    bob10....and here was a matriarch from Derby, sitting up finishing off a bottle of something or other, with all the boat's officers flaked out around her at the table. I declined her offer of a drink, noting that yes indeed, these Navy boys were pikers, and organised a boat ashore for her, with her departing words being something like "come up and visit me sometime" ringing in my ears.
    Geez, is she still alive!!!! I guess that you are talking about a few years ago! I worked for a couple of years on the old State Shipping Service up and down the WA coast in another life. There were a few ports where such things happened, just friends like! In Derby we used to sit the ship on the bottom along side the jetty and go on to tank circulation for generator engine cooling. Broome also before the deep water jetty was built.

    The first old ship that I sailed on did not have air conditioning, just "punka" fans. It was also all DC. The super that first allocated me to it said: "no air con, but that is much better, as with air con you just breathe other buggers farts"!

    If you have ever noticed small louvre panels in say, Office doors down low, well, that is where the air returns to the main system albeit it may pass through other open plan areas, say a General Office, to reach the Return Air Grille/Duct.

    It doesn't matter if the door is closed the grille can still relieve the pressure in a room & if it was a sealed door then it would tend to pressurise & in turn restrict air flow to that room.

    Sometimes with bad design a gap may be left beneath a door instead of a grille but that is very hit & miss & air needs to be recycled back to the main unit & that is where Ruby Princess & Mick's ship comes into it.

    You finish up with all people's 'goozys' floating through the air.

    Sorry missed that question somewhere.?? Opening the Port Hole buggers up the design conditions for that space & not just for that space, the whole system.

    Most people wouldn't give a flying **** so long as they have air but getting the quantities right means maximum comfort.

    The end of cruise ships, as we know them?

In other words, that 90% could contain coronavirus if it came from an area where someone had the virus.

    Thats not miles away from a land based system.
    From memory,a classroom needs 5l/sec per person in the room.
    But its a while since i have done a lot of AC design.

    So there is a 99% chance the staff on the Spirit of Tassie were telling porkies.
    They said “each section” - not each cabin The end of cruise ships, as we know them?

    The bottom line is, if the air can't relieve,it won't be coming in.So you will end up with one hot and stuffy cabin.

    These days i bet there is also some sort of Toilet exhaust system as well,which will take some of the conditioned supply air out.

    Section or whatever,it still won't be drawing all its air from outside.So it still comes from other sections or areas,or cabins,or wherever,,not full fresh air,which is what they implied.

    Sheesh. Yes, I would board a cruise ship if I was that way inclined ( I never have been, in case you ask ). Yes, I will get on an airplane. Yes, I will go to a shopping centre. Yes, I would go to my son's party.

    Are you now going to live your life based on some pathetic beat up? This virus is real, sure. Have you actually looked at its mortality rate compared to the usual flu? I'll bet not. The rates are incomparable, the flu is far worse, and the flu kills kids, but you are scared of something that kills the elderly or weak? I'm approaching elderly, and I am certainly weak compared to my younger self, and am I scared? No, I am not, and neither should you be.

    I can't believe the ignorance shown on this forum about this virus. It is a virus. They happen. People die due to viral infection. This happens every day. I'm sure you all know this. The thing that astounds me is that you don't grasp that this Covid is now here for ever. It is not something that has just popped up and will go away, it is now here for ever. Like every other virus. We won't beat it. We will adapt.

    This media driven panic will be repeated ad infinitum unless we learn that it's not the virus that's the enemy, it's us.

    Absolutely, and I was just about to post about it. Cruise ships tend to have a bathroom attached to each cabin, so with 2 or 3 thousand cabins that is a lot of air that has to be extracted. Good filtration of cooled air is also very important, but it is not possible to filter out a virus. Another problem with cruise ships in the number and size of public areas. Galleys and laundries also need separate ventilation in addition to air con, so that adds to the load of make up air needed.
