The end of cruise ships, as we know them?

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"!

Yep, she was a legend around those parts .Back in the early 80's. A few characters in Derby then. A few rough types as well. One of the local lads didn't like his girlfriend dancing with one of our sailors, and pulled a knife, tried to stab him. Not his lucky day, he picked on the only black belt Karate member of the Patrol boat Squadron, they cleaned the blood up, mopped the dance floor and carried on dancing. Tough boy spent the night in the cells. Some Patrol boats used to secure to the wharf and go on shore water at low tide. I'm assuming it was shore fire main, but we found the hole about 1/2 km from the wharf, and sat in it. Had to have a stoker constantly cleaning generator cooling water strainers. My memory of the wharf was the largest mud crab I've ever seen caught by a local there. Oh, and the nurses. [smilebigeye]

I reckon those blokes driving those ancient Leylands were the tough ones.

Depends on how the in port generator is set up. In later years I was on the rig tenders and we had a self contained "deck set". But then we did not need a great deal of power.

No in port generators, Two 371 series 40KW GM diesel generators. Not much more than a glorified fishing boat with guns, really. But did the job.

Marine Engineering notes for a general cargo ship. What should be remembered about Warships is they must have the ability to shut down to Condition Zulu Alpha, in the event of a biological or chemical attack.

Types of air conditioning systems -Ship service systems

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.

But it is possible to kill a Virus with UV.


Reading on about this as one does, & it appears likely an Electrostatic Filter Rack (EAC)(s) in the main RA Ducts combined with Ultra Violet Lamps in there as well may do an excellent job but even without the EAC & just UV treatment of the passing air, could be just what is needed to stop further infection recirculation on board Ships.

Of course the best time to do this is in the construction phase of the Vessel but could be a Field Add On if required & of course it will cost a motza but it is going to cost them that now anyway.

UV will kill Virus. I

I'm sure better engineering brains than mine will have thought of this. Won't they?[bighmmm]




Right, where did I put the Phone No of Princess Lines? [bigrolf]

If you go to the link below and scroll down to the Air Filtration section it says there is no air recirculation and all accommodation spaces are supplied with conditioned air drawn in under a 'total loss' system and then expelled to the outside.
Passengers are confined to cabins and public areas closed.
No C-19 cases reported so far.
The virus is not normally airborne, but lands on surfaces, which people touch. That's why masks aren't much protection as people don't normally breathe in the virus, but pick it up on their hands from touching surfaces.

Chatting to a fellow veteran at our exercise morning this morning, he told me he and his wife were booked on a cruise on the QE11 in Feb/March this year, got to Fishermans Island, and all passengers were lined up before boarding and asked to present their passports. Any who had been to Asia recently were not allowed to board. Everyone had their temperature taken, then those who were left were given the option of boarding for the cruise, or money back. I'm not sure how much information was provided about the virus, but he and his wife boarded. Off Cairns Border Force came aboard and interviewed every one, and took their temperature. [ that would have been a popular gig with Border Force, took a couple of days, apparently] They finished the cruise, no problems. Some time after when QE11 had arrived in her home port , they were sent an update from QE11 on the coronavirus, saying there were nil infections among passengers or crew.

The equipment (Machinery) would be sized accordingly & it would have it's own dedicated machinery space then & they are not concerned about grid electrical power to run the gear which a Land based system would be.

There is a lesson here for other Passenger ship operators.

Personally we have never tried to buy masks after reading about the problems that were had earlier. ie. being saturated with condensation, fit etc

I'm not sure what ships you are talking about 4bee but but I spent nearly 2 months on the Vasco da Gama late last year and the airconditioning system pumped vast amounts of air out of the ship to atmosphere via a quite large vent on the upper deck.

We went through a fair bit of hot weather for a few weeks and of course people were complaining that the air conditioning on board wasn't cooling their cabins enough.

I met the senior air conditioning engineer by chance and caught up with him on a couple of occasions. The biggest problem was balancing the system , he said 2 cabins side by side, one would say it's too hot and the other would say it's too cold.

Passengers would constantly adjust the thermostats never giving their cabin a real chance to stabilise.

But there was definitely no stale air on that ship.

I would say it is the same with all the cruise ships.
