The end of cruise ships, as we know them?

Nah, I don't drink vodka, gin or Scotch, so no loss. [emoji6]

I doubt if we will be returning to Tassie any time soon. The Navigator was most unimpressed when Premier Gutwin rudely said visitors were no longer welcome and should 'get out'. She mentioned it again only this morning, actually, when I told her about the ferries moving to Geelong.

The Port of Melbourne setup was poor with no-where for vehicles and caravans to marshall, so they backed up and clogged local streets, with cops hanging around looking to fine people. The Devonport end has a proper marshalling area and so will Geelong, so the move is a plus for ferry travellers.

It should also be noted that the Tassie ferry stays in the one area,so a specific system could be engineered for the climate in that region.

I was describing the Gucci hotel / ship / super yacht maximum comfort solution.

A lot of ferries and commercial charter boats have domestic reverse cycle split system units on the roof behind a cowling running down into the passenger area. These units are made for outdoor installation at your house so hold up very well.

Even if you throw away the external unit every 5 years you are in front. In this case you are working on cabin doors regularly opening to deliver doses of fresh air.

You need to allow for the condensate to drain away without flooding the local area.

Don't know about Australia, but Carrier used to make condensing units out of sheet stainless steel. No idea how much more they cost, but they certainty made servicing a lot easier.

That is an understatement of the year. Ok if one is cruising Freshwater, but if the vessel lives or operates within 2 km of salt water you can kiss the outdoor coil goodbye quite soon. Ally fins disappear just by looking at them. Alice Springs is ok.[bigrolf]

In my time, no manufacturer manufactured an Outdoor Unit with fins suitable for the saltwater environment &/or a house A/C on the Esplanade & good heat transfer, sure, there are coatings these days but apparently at great cost to apply, so it isn't done.
It is, as you would be aware, not just the salt water spray but the salt laden air as well so they need to be hosed off regularly with Fresh water on a regular basis probably at the Marina.
Never saw a unit base made from Stainless but that component could be easily be made to last from SS the way as SS prices seem to be dropping or were. Fan Blades could be pressed from SS as well. Then there are the Fan motors which need proper sealing of bearings & windings & proofing of their housings usually Die cast **** metal &/or ally. . Control panels can be remotely located but of course some components can't be & we all know the electrical conductivity of salt on relays etc etc
I doubt anyone would make a Compressor,Sealed or belt driven from SS.

Was that you you bastid? WW girls told me some codger calls in on a regular basis & blows snot all over their brand new screens. Next time I'll be able to say "I know him".[bigrolf]

OF, do you mean the cabinets &/ or condenser tubing & fins. I think they specialised in gear for rigs & seagoing vessels. Or did.? That would have been the USA & European side of the business.
Today they are a far cry from the Carrier of days of yore. I was a Carrier Dealer for many years but only used their gear for Commercial & Residential applications but did see the odd "Carrier Family" Publications. Even they, with all their Tech knowledge experienced some balls ups as they farmed out other makes with just their badges on those. A bit sad really as they were once a company that did great things in this field. As you know, it was Willis H Carrier . that invented the Mechanically Refrigerated Air cond systems.
in 1908 from memory. "Christ 4bee, how did you recall that but not 'er indoor's birthday? CAC brainwashed I suspect."[bigrolf]

Yes, it would have been equipment from the USA. I cannot recall just what the fins were, but the tubing was copper. Not much point in having a stainless steel cabinet without some better quality tubing and fins. On smaller American jack up type of oil rigs it was general practice to use air cooled condensing units. Most usually 10 ton split units, a couple on each accommodation deck. POS! Except the 06 compressors that rarely failed.

Big drillships had better marine type central systems with water cooled condensers. On rigs with SCR drive systems(most), the main switchboard, MCC and most importantly, the SCR panels were air conditioned spaces.

Nope I’m not joking that’s how Austal ferries and most do the pax seating cabin spaces. These are big boats though and they are behind a coaming and not directly exposed to the weather but definitely in the salty sea air. Any house or hotel on the seaside would cop a similar beating.

Same for outdoor bar fridge or freezer units on a boat. You can buy a super marinised unit for a zillion dollars or just a domestic unit for a few hundred and replace it slightly more often

Just had a Wiki wottsit on AUSTAL Ferries. A big crowd what? Ships don't look conventional ships anymore it seems. I guess it is Speed, MPG(?) & on some, RADAR "un-detection". Patrol Boats look like Starwars Props but they ALL would be very efficient at what they do.
