You realise that is just to run them on the mains when parked?
So they don't burn in excess of 10Te a day when sat there doing nothing but lights on, dishwashers and the like? Its is not to make then 'Electric ships
If they are so busy and active in the territories and doing the bits and bobs you mention, they wont be in Rotterdam that much surely.....?

All just IMHO obvs. smile
Really ??
They burn the equivalent of 5.000 diesel powered cars a year just sitting there "running the dishwashers".

And you can probably work out the emissions the entire port emits on a yearly basis. There's a reason why the average age in places like Pernis and Maassluis is sig. lower than the national average.

All in all, the last thing any ship owner wants is for the vessel to be either without freight / cargo on board, or in port.
It is not earning money.
But yet overheads (at a guess I would estimate £20k a day for Thialf, £45k a day for the Sleipnar) continue, ships mortgages, crew, maintenance, fuel etc continue regardless.

Hence : Expensive day. - Outgoings, no incomings.
Which is very obvious as well.

But you have a point, the results of Heerma these past years haven't been great:

'Lots?
Can you share with me which actually will be?
No, of course not, as I very clearly pointed out I'm no expert. But like you explained as well many sources claim the upcoming decommissioning wave.

Concerning the "old nasty engines" bit; Sleipnir is brand new and runs on LNG:

It 'can' burn LNG yes. it also and most likely burns MGO day to day due to availability of LNG. (cough Green Wash)
If you look to the Thialf, I think you will see it runs on a significantly different spread of powerplant, same for the others of that era.
50Te of fuel a day suit you ?...
And the rest of the industry (incl. oil tankers and container ships) run on composted flowers and angel farts ?
I believe the largest cointainer ships burn through 350.000 litres a day.

Sleipnir does seem to run on LNG from time to time.

I was being slightly churlish I admit on the 'dishwashers, but yes in principle - an idle ship with a minimum personnel on board.
one of our latest vessels on the design board and for 60PAX fully fitted with all the latest low power gear / LED throughout etc has a 'hotel load' of 400KW.
An older tub, significantly larger like the HLV's and with accom to 200-250, lights etc will be a lot more.
If they are in 'warm layup' - which unlikely just yet - they may be down to the minimum burn on the MGO, but I recall how we were under warnings not to use the Cranes for anything pithy, and even bring in a shoreside telescopic if viable.
I don't personally know the power set up on her, but assume an array of multi Gens either side of the bus board of large or small, (because DP) and ship can sit there with one large one small running. The Running of the cranes requires likely additional gensets firing up. And consumption.

I know the likes of the Swires WTIV's or Jan du Nul jack ups burn about 8Te a day doing nothing in port. more jacked as per the systems required etc.

There was a very strong rumour circling earlier this year that they were going under / Chapter 11.

The highlighted makes my point though - although I have no idea on the number you give. That is a vessel 'burning through' tramping on the seas, earning its corn so to speak, so semi justified.
The image that has led to this rabbit hole we are down is the opposite. Idle ships. No Income. Big overheads. 'expensive days'. Only one part of that is the Fuel burn sat doing nothing.

Shipping does have a problem. What is 'the next fuel' ?

LOHC is getting a lot of noise, as is LNG or even Ammonia.
Each have their inherent problem, not just 'on board', but infrastructure to support it. Furthermore in the conventional world of shipping, the cost of the fuel burning is intrinsic to the success of the vessel commercially in its operations.
Hence why so many relatively young vessels are being scrapped - like cars or trucks - they become uneconomical in the whole sense.
This goes beyond just the details of the fuel - for example : MGO can be burnt in cheap (Capex) High speed engines, but in less efficiency - vs. the Higher Capex medium speed or Variable speed DC grid engine set ups, and leaner fuel burn.
What does the customer want (or its corporate ethics demand?). Low Costs overall ? Low emmissions ?
Also to factor in the difference between Container / Deep Sea fleet vs. Construction stuff. The Container / Deep Sea fleet pay their own fuel - hence the mention in the other thread of the slow steaming, vs. the Construction stuff / ERRV / O&G - almost certainly to the customers account.


Very much also a case of which fuel will still be with us in this race in 5 or 10 years time ? the Betamax Fuel or the VHS ? (see also Laserdisc, DVD, etc)

Pics ? Not CGI biggrin


ETA: paperbag

Googlefu says they are not 'propulsion' and require electricity to get going, only creating 7-10% fuel savings..... when working I assume. At other times the windage must also be a nusance.

I'm pretty sure a flettner rotor stab is/was marketed.

Not a stab, definitely a real thing.

Your last was either an aircraft carrier, a Maersk B class or the QM2?

It carried very few containers and the accommodation was decidedly 3rd class.

That should narrow it down!

I wonder how the contract works for that.

Presumably the buyer has some long term fuel saving measure written in and so some of the risk sits with the seller.
